History YMMV / SentinelsOfTheMultiverse

* AuthorsSavingThrow: During the Rook City Renegades kickstarter for Definitive Edition, a reference to "[[HollywoodVoodoo Voodoo cults and primitive tribes]]" was left in Gloomweaver's update from his original writeup in 2012. The ''next day'', with the Realm of Discord update, Christopher made sure to include an apology for this and make it clear that the writeup in RCR was going to lean much less on problematic old tropes.

* CompleteMonster: Spite originally started out as Jonathan "Maniac Jack" Donovan, a petty delinquent and minor member of [[ArchEnemy the Wraith]]'s street-level RoguesGallery in Rook City. After getting stopped by the Wraith one too many times, Donovan became a SerialKiller, and after finding out the Wraith's secret identity, Donovan dropped her two best friends off a skyscraper [[ForcedToWatch in front of her]]. After finally being captured, Donovan avoided execution by agreeing to [[PsychoSerum secret drug testing]]. When the drugs granted him SuperStrength and other abilities, Spite broke out of prison and went back to his murderous ways, while also using any drugs he could get his hands on to fuel his new addictions. Spite's villain card deck reflects all this by often forcing the players to make {{sadistic choice}}s between saving victims or themselves, and his potential victims include a teenage wanna-be sidekick, an innocent priest in a soup kitchen, and a trusting [[WouldHurtAChild little girl]]. Even the heroes deciding to just kill him this time didn't faze him; when the demon god Gloomweaver offered Spite a [[DeadlWithTheDevil chance]] to be {{resurrected|Murderer}} in exchange for killing lots and lots of people to spread enough fear and misery to allow Gloomweaver to be summoned to our reality, Spite saw it as a win-win sucker's bet where he got to live again--even though resurrection is normally a very unpleasant occurrence in this universe--in exchange for doing the mayhem he wanted to do anyway. While nowhere near as powerful as other beings in the universe, Spite is as bad as it gets for a street-level villain.

* AntiClimaxBoss: Wager Master with his instant-win/lose conditions. The heroes can get powers, build themselves up, get all the combos they need and then Wager Master draws a card and the game instantly ends.

** "Who can say. Time will tell."[[labelnote: explanation]]A phrase frequently used by Christopher and Adam when asked a question they don't want to reveal the answer of quite yet.[[/lablenote]]

** In the [=OblivAeon=] portion of the storyline, one of the universes destroyed was the {{Telenovela}}verse which is exactly what you'd expect it to be: An entire universe based on "What if Sentinels but everyone acts like a character in a [[{{Telenovela}} Latin soap opera]]". Christopher's over-the-top LatinLover voice acting and the sheer hilarious insanity of the idea in general caused everyone to immediately fall in love with it and then go into Denial at it being gone. The begging for it to be brought back somehow got so numerous that Christopher eventually outright rebelled and said the more people asked about it, the more it was definitely staying dead.

* AlternativeCharacterInterpretation: Did the heroes of her universe ''really'' just choose to save five total strangers without trying to save Aminia? Or is that just an oversimplification of a more-complex situation that she's ignoring to have someone to blame? After all, she ''is'' mentally-disturbed.

** Heroes with deck control, like Visionary, The Wraith and Parse, are also popular, since they let you avoid the kinds of things listed under ThatOneAttack. Of these, Dark Visionary is considered "easy mode," since her deck control is her base power, meaning she can start scrying the villain or environment deck first turn no matter what.

** In Argent Adept's Supporting Cast episode of the podcast, one the characters they ended up creating was a sort of FriendlyRival named Soothsayer Carmichael. He was created as basically an opposite {{Foil}} to Argent: Nerdy and somewhat plain to Argent's flamboyant PrettyBoy, a book learned wizard to Argent's in-born sorcerer-like power, logical and CrazyPrepared to Argent's "hold my beer" tendencies, and tending to thus be constantly flying off the handle and ranting about Argent's impulsive, sometimes ill-thought-out approach to magic. He proved so popular that virtually all of the followup questions about the episode focused solely on Carmichael alone and Christopher noted that "you all love him, turns out!"

** America's Greatest Legacy is another BoringButPractical one - his power lets you choose any one hero to heal one health and use another power (including himself.) In practice, this means that his default power is always slightly better than the best power anyone has in play, allowing you to double-up on already-broken powers like Freedom Six Tachyon while regenerating health at the same time.

** Interactions between some of the heroes and [=OblivAeon=] rewards can get very silly. For example, Mr Fixer - something of a TierInducedScrappy in normal play - can combine Bloody Knuckles, Alternating Tiger Claw, Harmony, and Dual Crowbars with the Mecha-Knight to deal anywhere up to 25 points of irreducible damage to one target and 45 to another, with one power use, without even a damage buff from outside. Throw on other effects like El Mejor Legado or an [=OblivAeon Shard=] at high Doom and you can obliterate even the usually NighInvulnerable Scion version of Rainek Kel'Voss in seconds while also dealing heavy damage to other opponents. (The kicker? [[NintendoHard This may still not be enough to even slow down with [=OblivAeon=]]].)

** Wager Master's "What Do You Really Know?" Ongoing. It shuffles a card from each hero's deck into Wager Master's, and deals 4 psychic damage to a hero whenever one of their cards is on top of the deck (including when you reveal cards with someone like Parse or Visionary). It shuffles another round of cards every turn, is indestructible, and is ''not'' a Condition, so not even flipping Wager Master will make it go away - it's there forever. This can fast make a Wager Master game {{Unwinnable}} if you don't have the exact right things out in both your field and WM's. Wager Master has one Condition that makes killing him an instant loss, and another that lets you win by decking him out - but with "What Do You Really Know?" out, decking him out will involve taking a ton of psychic damage, so unless you also have Legacy with Next Evolution and Lead From The Front, or a tanked-up Scholar, it's going to be a painful process.

** [=OblivAeon=], in his first form (the one with 10,000 HP), has Tear Through Reality and Global Devastation. Early [=OblivAeon=] has a substantial damage buff (on top of being completely invincible until you've dealt with his Shield, which can be a painful process), and both of these will hit all of your heroes for enormous amounts of damage - particularly Global Devastation, which even bypasses the battle zones mechanic and hits everyone regardless of location. Impending Doom, too, is deeply the opposite of hilarious; if it goes off, which it does if [=OblivAeon=] is in that battle zone at the end of his turn, it does a ridiculous ''9999'' points of Infernal damage to everything except [=OblivAeon=] and his Scions - basically a guaranteed wipe of every hero in that area without the ''exact'' right cards, while only being useful against the Scions if you have one of the few damage reflection effects out. And for bonus points, if any of these moves take out an Aeon Locus while he's rampaging indiscriminately? He gets another play. And there are six Aeon Locuses in the deck.

** Infinitor, especially on Advanced, where he can play his entire deck in one turn and gives it all either damage resistance or a damage boost. This is especially nasty given the existence of Ocular Swarm, an obnoxious little creature that plays from the top of the deck and damages all the heroes whenever one of his Manifestations is destroyed - including Ocular Swarm.
** In team mode, Hammer and Anvil are obnoxious as hell. They're tanky for team mode villains, with 35 health between them - but they also have solid damage output, Hammer can't be brought down while Anvil is still active, and some of their Position cards provide them and sometimes all the villains with nasty buffs. And just for more fun, Position cards are neither targets nor Ongoings, making them almost impossible to remove.

* TooBleakStoppedCaring: {{Metafiction}} example. Part of the downfall of the Vertex universe was that its increasingly dark storytelling, with the heroes turning into villains, becoming antiheroes and/or dying, began to turn off readers - not helped by the glut of comics produced during the early popular period.

** While Mr. Fixer has ways to increase his damage, many see flaws in how he can't both boost his damage and get his special effects in play if he's faced with any sort of damage reduction. Using Hoist Chain (which debuffs Mr. Fixer's target) means forgoing the +1 damage from Dual Crowbars or Pipe Wrench, and using Driving Mantis (which allows him limited AttackDeflector effect), Alternating Tiger Claw (which makes his damage [[ArmorPiercing irreducible]]), or Riveting Crane (which removes his target's DamageReduction for a round) means forgoing Greased Monkey Fist's +1 to damage. One popular fix for him is the "Stance Shifting Master" custom variant, which boosts Fixer's Strike damage by +1 if he played a Style or Tool that turn. His official variant, Dark Watch Mr. Fixer, boosts his base damage to a whopping 3 instead of 1, with the caveat that he must destroy a hero equipment or ongoing card. While this can be painful, it encourages the player to use more of Fixer's equipment rather than falling into [[ComplacentGamingSyndrome the max-damage combo]], helps him push through his special effects when needed, turns Bloody Knuckles from a calculated risk to a risk-free +2 boost, and changes his overall team role from low-damage support into a carry that works best when he has friends feeding him cards to destroy.

** Of all things, a one-off joke from the Letters Page accidentally became one of the most popular set of characters. Specifically, the Secret Lads, a fictional book series about kid spies that has ''absolutely nothing'' to do with Sentinel Comics. Oh and by the way, this all happened because Christopher misread the branding (Secret Lab) on Adam's chair.

** After the Unity episode of the Letters page, any lettera relating to Unity will tend to end in #Sparks or #bringbackdebbie or both because of the in-universe hashtags that people who wanted to be contrarian would post post-Unity immigrating to the main canon.

** In-Universe, Sky-Scraper was one. She was originally intended as a briefly-lived character to highlight other sides of Thorathian culture and then be a SacrificialLion during [=OblivAeon=], but she was loved so much by the readers the writers changed their mind kept her around. This mirrors how in the real world C&A were going to do exactly that same story beat but both they and the RL fandom liked her so much they went with different ideas.

*** somewhat subverted if Luminary is on your team, as many of the cards in Mordengrad benefit anything with the 'device' keyword and there's plenty of those in Luminary's deck. Which makes sense, seeing as Luminary would possess the homefield advantage in such a scenario.
