- This page is has some quotes lifted directly from TWilde's huge plot analysis FAQ from Gamefaqs.com
- No, they're just to cover up his ominously repelling luminous crimson eyes.
- They're to hide his eyes. They are kind of the first clue as to his identity, after all.
- Or, he's one of the many Wesker Clones.
- Or, he's just a badass dude. An epilogue in Nemesis shows what his real face looks like.
- Another theory this troper has is that The U.S. Government was buying some of Umbrella's B.O.W.s.
- Or possibly contracting their in house security forces such as the Umbrella Security Service, and or Umbrella Biohazard Countermeasure Service.
- It could be possible that the government was investigating Umbrella long before the Raccoon City disaster.
- See Ada below.
- According to Resident Evil: Degeneration, they indeed knew.
- Even before that, when you check the S.T.A.R.S. office in Resident Evil 2, the fax machine spits out a report from the FBI describing their investigations into Umbrella and Irons.
- Well, that fax was a direct response for Chris's request for an investigation. There's no indication they were looking into Umbrella or Irons before the Mansion Incident.
- Even before that, when you check the S.T.A.R.S. office in Resident Evil 2, the fax machine spits out a report from the FBI describing their investigations into Umbrella and Irons.
- I vaguely remember reading something about Birkin being assassinated because he was planning to sell the G-virus directly to the government and reap the profit himself rather than letting Umbrella have a cut. Then, they got pissed.
- This has pretty much been confirmed by RE5.
- Interestingly enough, in the remake of RE2 leon asks Ada who was Umbrella selling these monsters to. Was it the US military, or some other military. Ada corrects him by saying they're not selling the monsters, but the virus that makes them. Notice how she didn't answer his question on who Umbrella is selling it to? Arguably that's a subtle dead giveaway.
The world of Street Fighter is one where even an atheletic schoolgirl or a morbidly obese middle aged hillbilly can, if they are willing to practice long and hard enough, become warriors with martial prowess that better fit in a Wuxia or Shounen Anime Fighting Series than in a mundane world. Since both stories are made and owned by Capcom, this a would comfortably explain the Power Seep Power Creep in Resident Evil that would allow an unenhanced human like Chris Redfield to go from a terrified boy in 1998 to a behemoth of muscle who can Megaton Punch a boulder into lava in 2015. Superhuman feats notwithstanding, Chris and Leon have demonstrated that like Kasugano Sakura (the aforementioned mundane Japanese Schoolgirl), years of endless combat and practice have also turned them into warriors whose raw skill alone are equal to the likes of Ryu, Guile and Sagat, as spectacularly demonstrated by the duo tearing through a horde of ''dozens'' of Zombies in Resident Evil Vendetta. Since neither men are explicitly superhuman, the world of Resident Evil sharing (and therefore having the same rules of spiritual growth for Warriors as) the World of Street Fighter is the safest explanation for their superhuman progress in the way of combat.
- ...is leader of a third organization.
- ...is a Time Lord. It had to be done! - Tofu
- ...is an agent for The Patriots, as well as all of the above.
- the fact that she wasn't present with Wesker during his final misson in RE5 only makes it obvious. Or she jumped ship at the right time.
- Maybe she's actually Haruhi?
- the fact that she wasn't present with Wesker during his final misson in RE5 only makes it obvious. Or she jumped ship at the right time.
- Ada has been in deep cover for so long she probably lost her own identity. In fact, Resident Evil 3: Nemesis hints at this. More or less Becoming the Mask.
- Resident Evil 5 hints at a biohazard incident in "the Orient" that Chris and Jill handled in the early days of the BSAA (but still pre-RE4). Given a name like Ada Wong, dollars to doughnuts says that she was probably involved in that as well.
- My headcanon is that she's an operative for the Family.
- He's still alive by RE5. He was seen in one of the latest trailers.
- He was still alive by RE5. Then Wesker punched a hole through him, and he wasn't anymore. Of course, he'd hardly be the first person in the series to come back from the dead, so he could still be a villain in future installments.
- Ooh, maybe he pulled the Wesker trick on Wesker, and when we see him next, he will have red eyes.
- He was still alive by RE5. Then Wesker punched a hole through him, and he wasn't anymore. Of course, he'd hardly be the first person in the series to come back from the dead, so he could still be a villain in future installments.
- Which is obviously why Umbrella was interested in it in the first place.
- Actually no, Umbrella itself was a front for Spencer, Marcus, and Ashford's BOW research.
- Perhaps the Herbs are in someway connected to those Progenitor flowers seen in 5? They said they were trying to home-grow them, but failed to make the real flowers; maybe these are just the diluted prototypes.
- The novels hinted at this, with Umbrella scared of the potential lost revenue from actually healing people, but saw its value as a military project.
- Barry Burton is our only hope.
- I can live with that, Barry is awesome enough to kick Wesker's ass, kill every zombie, and crush every Las Plagas into a Jill Sandwich.
- It's those 'herbs' they're always using to heal.
- Drug use would explain why Wesker, even before T-Virus, wore sunglasses all the time. At night, inside, inside at night...
- And it would probably explain their business plan.
- In my mind, there is no other reason why anyone would think making a virus that turns you into a man-eating vagina after impregnating your daughter and giving you over 9000 eyes would be a reasonable idea, let alone the thing you view as the pinnacle of your life's work.
- What cinched it for me was Code Veronica. At one point, Umbrella's upper management thought it was spiffing to have a sociopathic 12-year-old as the head of a research project. William Birkin basically gets insulted because of how ridiculous this is, and this is a man who spent his entire life creating a virus that turns a man into what I can only describe as a hlphrph. I don't care how smart she was, she was TWELVE YEARS OLD.
- This is actually a touch of Truth in Television, many "prodigies" usually are woefully underequipped to deal with the adult level expectations placed on them, so they end up with some kind of complex to deal with it, unfortunately Alexia and William (who was a prodigy himself), both ended up with a God Complex.
- Jossed by RE5. Though ironically, the "Stairway to the Sun" flowers operate almost exactly like you described.
He also goes to considerable efforts to get his hands on the Plagas. The Veronica virus and the Plagas have one thing in common — the queen unit can control all the others in some way (Plagas by ultrasonic signals, Alexia by... something). Most likely, Wesker wants to get his hands on both of these in order to infect everybody with some sort of hybrid, over which he will have complete control and thus become ruler of the world.
- Tofu: My secret is revealed! DX Back to the Evil Overlord List.
Another theory is he was just a Player and came back after, no modification.
FINALLY, he could also have during his game became Composer. This explains how he knows everything — it's all a Game and he's the one behind it. Ada Wong is his Conductor. And since Oswell E. Spencer masterminded Wesker, that makes him the Producer. Chris and the others are innocent Players. He took an extra entry fee — he took their memories (crafting new ones to replace them) and their common sense ("We're in a zombie infested mansion! Let's split up, gang!") and hence, he's just playing an overly long and drawn-out Game because he has nothing else to do aside from dominating the world, but with Chris there, he can't, thus keeping it interesting.
- As a matter of fact, Word of God says that Jill is straight up immune to the T-Virus.
- She was vaccinated against it in RE3, yes.
- In addition, not everyone becomes a zombie after dying. Kenneth, for one. None of our protagonists. Rebecca doesn't if you let her get killed by a hunter in the R Emake.
- Rebecca doesn't become a zombie in the R Emake because the Hunter cuts her head off.
- That's only in the original. In the REmake, it just cuts her throat. That said, somewhere in the Resident Evil wiki, it mentions that 10% of people don't have any reaction to the T-Virus, but I can't be arsed to look it up just now.
- Another stroke against this is because many of the protagonists die in much worse ways than zombie bites, while some do regenerate as zombies. Kenneth doesn't get a chance to come back a zombie due to the zombie devouring his neck to the point of a pseudo-decapitation and Enrico gets shot. Likewise, Brad Vickers becomes an unwitting victim to naughty tentacles, returning as a zombie, and Forest, while pecked to death by T-Virus infected Crows, comes back as a zombie. Other characters you can find in RE 3 are either dead from other things or their own suicides.
- Rebecca doesn't become a zombie in the R Emake because the Hunter cuts her head off.
- Don't call it a comeback! He's been here for years!
- Tofu: That is both terrifying and entertaining. More info plz.
- Would that make Birkin D-Shay and Krauser Earthquake?
- Heck yeah! Bring on the crossovers!
- Yeah, that's what they said in the Caliban Cove novel, and we all know how the rest turns out.
- Maybe all of the zombies are normal people, and are just seen as zombies because of the protagonists' drug-induced hallucinations
- Or not. It's generally accepted amongst RE fans that unless it's explicitly mentioned in a file or shown in a cutscene, none of the protagonists are injured and infected for the duration of their scenarios. In other words, ingame bites, slashes, and whatnot attacks inflicted on the protagonists are non-canon, and are merely part of the game mechanics as opposed to driving the story on.
- However, Jill got infected because the Virus was not only directly delivered into her body, but also due to it being mixed with whatever Nemesis was oozing.
- That could also mean that Tyrants are immune to virus people, that were kidnapped from Racoon City when their immunity was discovered.
- Actually, there is a lot of canon info that pretty much says that. Not the kidnapped part, but a VERY small percentage of people even can become Tyrants, and they wouldn't succumb to the virus under regular circumstances. Even a smaller percentage can become a Nemesis.
- I always figured that is exactly why Wesker chose them to be S.T.A.R.S members, not because of their skills, but because each member was found to be resistant to the T-Virus, after all, it would be child's play to get a blood sample during the interviews, under the excuse of "advanced drug screening", why else would they hire a fresh out of school 18 year old as a special terrorism squads medic? After all it would be difficult to get "combat data" from them if they all died straight away from one scratch.
- That could also mean that Tyrants are immune to virus people, that were kidnapped from Racoon City when their immunity was discovered.
- To use another R Emake example, Wesker is shown being "killed" by the Tyrant in two different ways. After the first battle with the Tyrant, on Jill's side, Wesker's body is gone. On Chris's, it's still there. Chris only assumed Wesker was dead instead of actually checking (he has less medical experience than Jill and Rebecca, as demonstrated by his inability to make V-JOLT), making Wesker's return in Code Veronica that much more surprising to him. It's also no coincidence the character you're playing as gets to destroy the Tyrant with a rocket launcher while the other one is apparently unconscious. And then previously in RE 0, Rebecca previously had two run-ins with a Tyrant, as well as countless hunters, but in Chris's story, she's relegated to possibly getting killed by a hunter if Chris doesn't save her as she cowers in fear. Now that we know Chris likes being thought of as a badass who saves the day, is it any wonder why he apparently looks like he was ripped out of an action movie in RE 5?
- That also explains why, when playing as Sheva, you realize his AI is stupider during the boss fight with Jill. Make of it what you will. ;)
- Another example is Darkside Chronicles, seeing as how it's Leon retelling the events of RE 2 and RE: CV (which he wasn't present for). That could also explain the completely different architecture in the boss fight with Steve. Claire probably didn't go into very much detail about it, because Steve died, so Leon described it differently, based on what he thought it looked like. That also explains why Steve's heart is exposed, Alexia looks much more like a plant, characters were working together at points in time when they wouldn't, Wesker and Chris didn't fight Alexia while Claire dealt with Steve, etc. He just interpreted based on what he was told by Claire, thus explaining why Chris's portion wasn't touched on while Claire was in Antarctica.
- It also explains why Alexia is so much more evil: somehow, I doubt Claire was very charitable when it came to describing that witch.
- Yet another is Umbrella Chronicles' interpretation of Resident Evil 3: Nemesis. Wesker is the narrator. He had almost no way of knowing the order of events and what happened, because there's no way that Jill would be on speaking terms with him after what happened in the Arklay mansion and there weren't surveillance systems set up. That explains why the places Jill and Carlos fight the Nemesis are unusual, where his mutations happen are different, Jill is able to access the other side of the police station than in Resident Evil 3: Nemesis, Nicholai and Mikhail aren't there, Carlos lost his accent, Jill's kept in roughly the same area throughout the whole thing, the Gravedigger comes up out of the ground in the middle of the city rather than the graveyard, Jill doesn't get infected, etc.
- Suddenly experiencing massive growth without any apparent intake of mass from their surroundings — the intake has already taken place off camera, through massive intake of biological materials stored across their body.
- Regenerators and Iron Maidens regenerate tissues by converting stored matter into new limbs, eventually dying either when their organs are removed from the body or they run out of mass.
- Seemingly humanoid opponents being able to take massive damage from bullets — their bodies are effectively bullet proofed by layers of this super dense material.
- Lickers' brains are coated by this material, even though they're on the outside, stopping them from being one-shot-wonders.
- Chris Redfield apparently has a mutated form of the virus, manifesting itself as hyper-dense muscles, as do other protagonists. They heal rapidly because herbs are actually very dense as well — explaining why you can only carry a small number of them.
- It also explains things like tyrants, and Wesker, being able to catch rockets. Sheer strength alone would not allow that.
- Las Plagas hosts and T Virus infectees are both notably stronger, considerably tougher, more vicious, less hygiene-oriented, and can be controlled by a master organism (in the case of the Code Veronica version). The reason that Las Plagas victims are more cunning and less brain-chomping is that Las Plagas is a purer version of the T-Virus. In fact, the T-virus was Umbrella's attempt to recreate that superhuman effect, using the T-Virus to make Alice-quality super soldiers. (It results in many a One-Winged Angel in the game continuity because Las Plagas doesn't exactly work like Umbrella thinks it does.)
- If Las Plagas really is a primitive T-Virus, that explains how its fossilized spores can still be alive after hibernating for millions of years.
- Saddler probably worked for Umbrella, researching the Plagas fossils, but thought that using them practically was a pipe dream... until it wasn't and he figured it out. Saddler went rogue and used his research findings to make his own mind control cult, not being content with simply using bio-organic weaponry to conquer the world. Meanwhile, Wesker was not amused and sent Krauser and Ada to steal his research, seeing as that's the kind of information gold-mine that could put Umbrella (or a similar company) back on top.
- Why else would he ALWAYS have gloves on? I'm thinking either A) there was always something wrong, and the T-virus made just that worse or B) The T-virus did something that fucked his hands up, thus the gloves.
- Dude, 90% of the cast wears gloves. Although, that might make it worse.
- The guy Leon faces is a male, and is holding a machine gun, and seems like he's not afraid of the zombies. They're both male survivors, so they fit the bill.
- Jossed. He's a different guy named Sacha, a.k.a. "Buddy."
- No... Wesker's a clone of Johnny Bravo, with a bit of Duke Nukem for good measure.
I've been playing Darkside Chronicles recently, and fighting G when I noticed something. Birkin's initial transformation was a shambling, asymmetrical abomination. However, he was still conscious in there. Remember the "SHEERRRRYYY!"? He's actively searching for his daughter, but he's completely mad by this point. I have more proof, but I'll get to that in a moment. Birkin had never been sane to begin with, but after the G-Virus injection he went nuts.
Anywho, Birkin's crazy, but he still believes the G-Virus to be the perfect weapon and the pinnacle of his work with Umbrella. Logically, we can infer that he believed anything created from it would be perfect as well. With this in mind, let's take a look at each stage.
G1 was his initial transformation, and like I said before, it was a mess. He could barely walk, his body was obviously wracked with pain, and he didn't even have any natural weapons — the intial claws he developed either degenerated or were unsatisfactory for his use. Instead, Birkin was smart enough to use that pipe, but he could still only move quite slowly towards his prey. Obviously, this is a far cry from the perfect creature Birkin envisioned. Now, applying Wesker's theory, if Birkin wanted to be a perfect creature, obviously something needed to change. This is where G2 came in.
G2 was an even more grotesque stage than G1, and also raises a couple of interesting questions. First, though, this form is far more deadly than before. It can leap great distances and finally has some natural weapons: those swordlike claws on his mutated arm. On top of this, Birkin is faster now and sneakier too. He deliberately sets up an ambush on multiple occasions in this stage and the later ones too (the cable car, the elevator, the train, and in DC, that big hub room where you fight him three times in a row) and uses his newfound leaping ability to his advantage on that elevator fight too. However he still lost, and obviously this form's asymmetrical body was still incomplete and imperfect. More changes were needed.
G3 was the next stage and arguably the perfect superhuman creature Birkin hoped for. Look at it: The musculature is pristine, it's developed armor over its vulnerable midsection (something that gives it an advantage over most Tyrants), and it just looks like a finished product. Moreover, it's fully mobile now; look at the acrobatics it displays in DC! Even in the original RE 2, this form moved quickly. In stage 2, we saw Birkin's head get shoved into his chest cavity in favor of a new, mutated skull. However, he's far from stupid in G3. He's feral, but clever: he shields himself with his arms, he displays a bizarre roundhouse kick, and employs sneak attacks and various unique acrobatic movements that seem out of place on something that fights on instinct. Also, G2 recognized Annette and didn't even attack her until she pulled a gun on him (again, DC only). This implies that Birkin's memories and intelligence were retained in the new head, which leads my to thinking that his brain was still there or that information was "copied over", so to speak. This also explains how he knew which areas to avoid when rampaging through the underground lab. Notice you don't see him in any of the poisoned rooms or the smelting areas where he could fall in and get nearly roasted alive.
Now, astute readers that have come this far through this wall of text may wonder if this convoluted theory applies to the last two stages. Many people say that G4 was a great big step backwards... but I'm not so sure about that. Birkin's become an even greater killing machine than before. His attacks can kill Leon and Claire in about two or three bites, and in DC he's fixed another flaw as well. He's developed a new long range attack: that acidic vomit akin to the G-Creatures he later spawned. Birkin even set up an ambush in this stage too. Okay, he was in stage 3.5 (notice the expanded rib cage and new head), but it still counts.
Now, for G5 and how it fits in with the "Birkin's mad idea of a perfect creature shaped this form". Actually, I think this was another intermediate stage, like that 2.5 version we saw in the cutscenes of RE 2 and the 3.5 form we fight briefly before he became G4. Birkin has been eating everything he can find; zombies, lickers, lurkers, and possibly other survivors. As result, he's evovled into a giant blob... or a cocoon. This is pure fanwank, but he might have been trying to develop into something possibly even more powerful than before, only he got sidetracked by that explosion. He's still in there, as my signature (and more importantly the cutscenes in DC) prove; Birkin's crying out for his daughter even after becoming this abomination.
In conclusion, right up until G5, Birkin had been steadily evolving into a perfect killing machine. He's still intelligent, but he's so insane after the transformation that he's lashing out at or impregnating anything that moves. However, with each transformation, he becomes more efficient, more deadly, and more of the perfect creation Birkin may have envisioned. Wesker's theory may have some credit after all.
- *sigh* You're a little late to th- no, you're a lot late to the party with the weed jokes. Besides, mixing herbs on sheets of paper is how traditional medicines are prepared in Japan, and take a wild guess which country the Resident Evil series was developed in.
- Didn't know medicines were prepared that way. But if you didn't know that, how would you think their "herbs" were used?
- Before RE 5 showed the spray bottles, I assumed they were used as a poultice. Forgive me if I sounded a bit douchey earlier, but us RE veterans have been hearing the pot jokes since 1996, and they haven't aged well at all.
In the next game, Wesker will be the protagonist, or at least one of the good guys somehow.
We will finally learn about HUNK.
Jack Krauser will return; he can survive that barrage of bullets from Leon, so it's possible from him to recover from his encounter with Ada. We the player aren't 100% sure he died, and Ada doesn't know everything, so how is she so sure that he died.
Leon & Chris could team up.
The creators will try to add a little sexyness to the new game.
- Wesker's "son" is indeed the third protagonist of RE 6, and Chris and Leon will finally meet up for sure, if not necessarily team up. No info yet on the other guesses, but on a WMG page, two out of five is a pretty good average.
The problem is that neo-mitochondria are not all that cooperative and have their own goals in mind. The second Ultimate Being being created in the base under Dryfield was definitely not part of the plan, demonstrating that the researchers had pretty much been taken over by the neo-mitochondrians at that point and were no longer doing the research for Umbrella. The ANMC pupae being converted from a factory for the viral NM vector to a womb for the new UB is proof enough that Umbrella's plans were off the table.
The reason the President is pressured into firing the space cannon at Dryfield is because Umbrella needed the place cleaned up or at least too damaged to be linked back to them, and nothing cleans up messes like giant space cannons. Umbrella likely ceased to experiment with NMCs shortly afterward, focusing back on their original virus-based research. Dicking with neo-mitochondria, while tempting, would almost inevitably lead to any attempted programs being co-opted by the little parasites into creating another Ultimate Being and trying to cull the human race. Unable to guarantee control over them, Umbrella would abandon them to focus on much more manageable viruses and megalomaniacs.
Dino Crisis happened as well, but it was caused by a minor Umbrella subsidiary, one focused on energy generation for military applications. It didn't go very far because uncontrolled dinosaur summoning isn't very useful for energy applications, the time-travel bit is nigh-impossible to control (And even Umbrella would want to avoid dicking thing up with paradox-es), and turning dinosaurs into BOWs would take a lot of extra work for not a lot of gain, as the number of dinosaurs transported to the present is pretty limited. And being a subsidiary made it very easy to simply leave them holding the bag, especially since it involved almost none of the usual zombies-and-tyrants you see all over most Umbrella's viral outbreaks.
Aya and Regina both end up as part of the government's anti-Umbrella taskforce, as they are both federal agents and their own experiences during their adventures make them uniquely suited to dealing with the organization's bioweapons. Regina and Aya have dealt with creatures just as dangerous as any Umbrella bioweapon, and Aya is probably both immune to any viral issues and can set things on fire with her mind. Also, both of them have fought a T-Rex, so they'd probably get along famously.
Also, The 3rd Birthday never happened because screw that game.
- That's not so much WMG as it is hitting the nail squarely on its head. It's also likely the reason Revelations 2 appears to be scaling it back to more of an RE4 style.
- Brad was also aware of Nemesis' mission to kill S.T.A.R.S. members (beyond Nemesis simply saying "S.T.A.R.S."), implying Nemesis has already killed at least one. The only surviving members after RE 1 are Chris, Jill, Rebecca, Barry and Brad. Brad dies at the start of RE 3, Barry is confirmed alive at the end of the game, and of course Jill and Chris are still around. However, Rebecca has not been seen in a game since, lending strong evidence to the conclusion above.
- Possibly confirmed as true, the official Biohazard/Resident Evil companion book updates every character's status, and Rebecca is listed as deceased around the RE 2/3 time period. It appears that Nemesis found her...
- This has likely been Jossed, actually. There is a pre-RE6 stage play in Japan known as BIOHAZARD THE STAGE that was overseen by Capcom themselves, meaning it's either canon or the next closest thing. In it, Rebecca is shown to be working as an university professor and also serves as an advisor to the BSAA, much like Barry in Revelations 2. She's even been on several containment missions and has been active since at least 2005, one year after RE4 and the same year the events of Degeneration took place.
The old gang would still be around and make their presence known at times, but, like in their respective outings, you get the sense that they're part of something bigger and more important. In the case of the "BSAA rookie" scenario, Chris and Jill could come in during one particularly harrowing section (perhaps finally confirming whether or not they're a romantic item, hm, Capcom?) and bail you out before going off on their own action-packed adventures. If our "heroes" survive, maybe they're taken in by the government and given an offer, complete with Leon making a cameo and telling them the same thing happened to him years ago. Or maybe they're working for TerraSave under Claire's watch and their entire reason for ending up in the crossfire is because of a medical assistance response gone horribly wrong.
Along the way, the protagonists are aided (over the phone, via e-mail, etc.) by an enigmatic figure who knows far more than they let on. If it wasn't for the events of Revelations 2, I'd say their anonymous benefactor would be revealed as none other than Alex Wesker, the last of the "Wesker children," using the heroes to achieve currently unspecified means, but it could always be someone else working behind the scenes. Jessica's still running around out there, isn't she?
The resultant global fallout will make Raccoon City, Tall Oaks and Tatchi look like an average day instead a news worthy incident. In response, the BSAA resorts to calling in every known survivor of every previous bio-terror attack to counter this threat.
Bonus points if it's from 1) a disillusioned member of The Family, 2) it's current unknown leader, 3) leader of the third organisation, 4) one of the protagonists going through a FaceāHeel Turn to prevent kids in the future from learning the alphabet with the viruses.
He knew that Spencer was behind his fathers death, but being on the board, also knew of Project Wesker, in order to attempt some form of revenge/leverage against Spencer, Alexander decided to eschew Spencers method of creating a "superior" race (eugenics) and cloned a known "superior" ancestor, Veronica, who was a genius, he also knew about the W-Virus, but knew of it's abysmal success rate, he hoped that his children would create a virus similar but with a less crappy success rate, he was on the money, as T-Veronica, despite needing a lengthy incubation time, is compatible with anyone if they do so, problem was The Twins had the same issue that Project W had, that the children tended to be a bit rebellious when they discovered their origins.
The main problem is the mutations tend to happen way too fast, are too unstable and unpredictable, and spread too easily to not cause outbreaks wherever they appear. As we saw with Albert Wesker and Carla Radames, it's possible to take time to produce a successful final product of a virus. Wesker needed regular upkeep, but his superhuman abilities were otherwise 100% under his control, as was his grasp on sanity (complete global saturation goals notwithstanding). Carla was successfully made into a perfect clone of Ada Wong via the C-Virus, and only became a villain because she was still Carla, and went crazy because of the experiments done to her, not because of the virus itself.
Some enemies, like Rachael Foley and the Skagdead communication officer from Revelations, still seem to maintain their original personalities despite the horrible mutations (especially those two, as journal logs/data files show that their mutations happened slowly compared to the more common enemies, and they were aware the whole time). Sherry Birkin still has the G-Virus in her system, but it grants her the benevolent effect of rapid healing capabilities. It seems like many of the mainline viruses could ultimately be beneficial for humanity, if only they didn't cause freakish violent mutations, and had plenty of time to properly bond with the host subject.
When Chris and Rebecca first meet each other, why doesn't bother to say anything to Chris about about the ordeal she just went through and all the monsters she's fought in Resident Evil Zero. It's not like she needs to mention Billy in order to describe the evidence of Umbrella being up to no good she's discovered, so why doesn't she bother to say anything? "Hey, Umbrella has a massive underground facility that's producing zombies and bioweapons" seems the kind of thing to mention to Chris at some point.
This is, of course, because RE Zero came out 8 months after the remake of the first game, but if you assume the events of RE Zero happened, it makes Rebecca's failure to mention anything really odd. RE Zero doesn't have anything in it that explains why Rebecca stays silent about it afterwards.
The scenes where she cowers in fear of a hunter (it's possible to get the best ending in the PS1 version without triggering this) and the scene in the remake where she stands in front of the Tyrant and needs to be rescued by Chris also feel unusual given she's already fought numerous enemies, including having killed a Tyrant by herself. Why has she suddenly forgotten how to handle something she's faced down already?
The best explanation I can think of is she tripped and fell, and hit her head on a rock on her trek through the woods to the Spencer mansion. Her headband is actually being used as a bandage for the bump on her noggin, and the combination of the trauma and the injury has made her completely forget the events of RE Zero.
