* ''Battle Network 2'' is notorious for the Darkness ([=DarkMessiah=] in Japan) PA (Bass V3 X + [=AntiNavi=] X + Any Gospel chip X), where Gospel appears and uses his dark breath on the front and middle columns of the enemy's side of the field. If anything survived the initial onslaught, Bass would attack the back column. The kicker? Both attacks did 3000 damage each. The first attack alone is enough to [[BeatThemAtTheirOwnGame kill the final boss himself in one hit]]-- and it pierces shields, so you don't even have to wait for him to open his mouth! however this PA brokeness is actually balanced out by the fact the gospel chips are hidden event only chips that never saw official release outside of japan this PA was unobtainable without hacking outside of japan until the virtual console release of BN2, which made available the event chips by just accessing the Network option in the game, plus the secret chips obtained through netbattles in compensation of the lack of connectivity between cartidges, so have fun.

** Variable Sword is considered the second most broken standard chip in ''[=BN3=]''. The most broken goes to Sensor. What did it do? It puts a Killer Eye in front of you that checks in a straight line had it been put on the middle line (diagonal otherwise). If it hits, it does damage that pierces MercyInvincibility and stuns the victim, and the eye is active for a long time. It doesn't deal as much damage as Variable Sword did, but it forces you to stand on ONE row and being open to attack, or move and open to attack and with proper timing, it can even stunlock. It's even more deadlier if you supplement this chip with Icestage, which doubles electric attacks on ice. With this combo, most of the bosses can be taken down quickly and you can easily obtain the V4 chips.

*** not just the stunning chips these 3 codes also have access to several extremely reliable and powerful Program advances and chips to make use of the plentiful stunning chips the E code alone has the most of any single letter coded PAs and the F code gets the Hyper Ratton PA which meshes extremely well with Flashman powerful stunning capability and P code gets access to use evil cut PA which chews up most things one-on-one as well has like hyper ratton benefiting from a navi that has a stun effect (plant man) to ensure you can land it.

** Also in regards to ''Battle Network 5'', the S code is notorious for being rich in practical chips with respectable power. It allows one to at least have a easy time playing the game to the end.

* Dark Chips from ''Battle Network 4'' made the game a joke. If you used them enough when you got the option, you'd eventually get the option of starting out the battle with them. Of course, they removed 1 HP permanently every time you used them, but it was a relatively small price to pay for being able to curbstomp everything in the game in one or two turns flat.
** Unfortunately, it came with three major drawbacks.
*** First: you can not use Dark Chips against the final boss, so good luck fighting him with reduced HP.
*** Second: It prevented you from using "Light" chips like the [=NaviSP=] chips. While this was supposed to balance out the fact that you can now use "Dark" chips like Muramasa, it ended up failing hard, as the Light chips are vastly superior.

** Of course, using enough Dark Chips means your base max HP will be reduced to 1... But you can easily place a pair of HP+500 programs in your Navi Customizer to counteract this, as customized HP can't be permanently lost from Dark Chip usage.

* In ''Battle Network 5'', you could combine Dark Chips with [[PowerOfFriendship Soul Unison]] to produce "Chaos Unison". It gave you ''the Dark Chip as a free charge attack''. It's at least as buh-roken as it sounds. Proto Chaos and Toad Chaos are popular for getting perfect S-ranks on RandomEncounters - a 400 damage {{BFS}} or a 300 damage {{BFG}} that wipes the entire field. They only lasted for a turn, but that's if somehow you need to enter the Custom Screen again. The way it works is that the charge rapidly cycles between purple and green. Releasing the charge when it is purple uses the Dark Chip with no ill consequences, but missing the timing and releasing the charge when it is green again disables the ability and releases an invincible [=DarkMega=] on you. While Chaos Unison was supposed to have a 50/50 chance of backfiring, the timing for attacking isn't too hard to do reliably and you can also abuse the pause button to stop the cycling. If it is purple, you can safely release the B button and resume, for it will successfully fire every time.

** Or in BN5, Chaos Number Soul. Its charge attack is Dark Plus, which means +50 damage for the selected chip.

It's at least as buh-roken as it sounds. Toad Chaos and Proto Chaos are popular for getting perfect S-ranks on RandomEncounters - a 400 damage {{BFS}} or a 300 damage {{BFG}}. They only lasted for a turn, but that was generally more than enough.
** The Chaos Unison had another game-breaking exploit: When fully charged, the charge would rapidly cycle between purple and green. Releasing the charge when it was purple used the Dark Chip with no ill consequences, but releasing the charge on green makes it backfire on you. While they were supposed to have a 50/50 chance of backfiring on you, pausing would stop the cycling, and if it was purple, you could release the B button then resume, and it would successfully fire every time.
*** Shadow Chaos. Its Dark Chip, [=DarkInvis=], makes you invulnerable to ANY attack and causes Mega to go berserk, not responding to your controls... but renders him able to use ANY chip or [[LimitBreak Program Advance]] you've used previously.
*** Search Chaos, especially when the enemy is area rowlocked. The target will instantly eat somewhere in the realm of 800-1200 damage as a result. The attack also completely cancels out the two most common forms of defense, [[MercyInvincibility Invis]] and Anti Damage! The only thing that will completely prevent taking damage from this is a Life Aura + Sanctuary combo, and everyone knows how hard that is to set up.
*** Number Chaos. Charge it up and your next attack is now 50 points stronger. This makes some multi-hit attacks extremely powerful without the aid of other chips; for instance, the Super Vulcan mega chip now deals ''620'' damage.

* Prism. Any non-breaker attack that hit it will be reflected to all spaces around it. This made it easier to aim attacks as you just had to hit a stationary object if you managed to land the prism in the middle of the opponent's field. Problem is, it also turned attacks that hit a wide area into multi-hit attacks that have all the hits register at the same exact time. The way it worked is if you hit the opponent but the attack also hit the prism, the opponent would take damage from the hit AND the damage from the splash damage reflected on to them. This effectively doubled damage and was used well with LifeSword, DoubleHero (which turned a GameBreaker into a [[UpToEleven Game Destroyer]]) and was the basis for Disco-Inferno, a chip combo that utilized the normally average Heat Spread Program Advance. The idea was, as a spreading attack, it would hit the opponent for 300 damage, with another 300 from the prism. Couple that with Grass Stage and you instead deal 600 damage with 600 reflected back, leading to ''1200'' damage instantly. If the opponent is weak to fire, then the first hit is doubled, having 1200 damage with 600 reflected back, leading to ''1800'' damage. If you're playing multiplayer, very rarely will you find someone who has more than this, and if you do, there's a high chance they won't be much trouble anyway.

*** Third: You'll get raped in multiplayer.

* Anti-damage. There are several chips of this type, but each are specific counters to types of chips (Anti-fire, anti-wood, even Anti-navi and Anti-recover), but as the name implies, Anti-damage will counter ANY source of damage. By which we mean it negates the attack and fires back with a near instantaneous barrage of nigh-undodgeable shurikens. BN3's Anti-damage fired off three shurikens for 100 damage each, and these chips were UNLIMITED. It was nerfed in later games to only throw one, classified as at least a mega chip and made so some attacks could get through, but still a respectable chip in it's own right.

** Don't forget most of the Navi chips. Entire ''folders'' have been built around [=FlashMan=], [=PlantMan=] and [=BubbleMan=]. The first ignores MercyInvincibility and stuns, the second pierces guards (Looking at you [=DrillMan=]), hits multiple times, and immobilizes the enemies, and the last hits an insane number of times (the final one hits around 20 times), with each hit possibly doing over 120 damage depending on how many Aqua +30s you attached.

*** Number Chaos. Charge it up and your next attack is now 50 points stronger. A Super Vulcan now does 720 damage.

* Folder Return is ''Battle Network 3'''s resident Bad Idea. Where do I start? It returns every single chip to your folder, including ''itself''. It also functions as a Full Custom, restoring the turn gauge so you can instantly pick your freshly recycled chips and continue your assault. Your opponent also gets the intermission screen, but they're not the ones with a totally fresh deck. And it's got the * code, which means it goes in ''everything''.

<<|GameBreaker|>>

* However one of the most infamous, and due to it's nature farthest reaching combo, the Silver Bullet Combo. Essentially, when an Atk+10 chip or something like it is used on a multi hit chip, that modifier applies to each hit. Same goes for Full Synchro. The Silver Bullet involves using attack boosting chips (And optionally a stunning chip) with one of the Vulcan Chips. Now, with your standard Vulcan chip (3 10 damage shots) this isn't so bad... but in later games, they introduced a Megachip known as the Super Vulcan (12 shots) and they had the Color Point chip mentioned above. And every shot doesn't allow for mercy invincibility, and stuns the victim long enough for the next shot to hit. With color point, thats approximately 70 damage per shot, which is 840 damage with two chips.

* In general, there are 2 chip that is the single most game changing chip in the entire series starting from the second game, First is Area Grab, which is a simple chip that takes one row from the opponent's field. Second, is Full Cust, which as the name imply instantly fills the custom gauge. The former allows you to control the field, and essentially increases your winning chance by having more space to move, and how easy it is to score your attacks. The latter is a simple, yet deadly tool for increasing your folder speed. It's even more prominent in the second game, where you can have FIVE of them in your folder.

** Don't forget Recycle -- it, too, can, in the right hands, become a Game Breaker. How so? It will literally recycle ANY Navi chip that was used last. That includes fellow Giga Chip Bass (which deals a truckload of damage and [[UselessUsefulSpell normally requires a special panel to exist for it to work]]), even if the Dark Hole that's needed to use the actual chip is nowhere to be found. Let's also not forget that it can also recycle any of the OTHER Navi chips, essentially letting you use the same Navi chip TWICE (which is especially bad for your opponent if you happen to use a multi-hitter that they're weak to -- like [=BubbleMan=] or [=PlantMan=]). Even better, it keeps any bonuses you had when you used the first chip - e.g. Atk+30s.

* It gets better. In ''Battle Network 3'', thanks to [[GuideDangit Compression Codes]] for Navi Customizer programs, it was possible to use the [[{{Synchronization}} HubBatch]] program (which gives you AllYourPowersCombined, literally - every Style Change from ''Battle Network 2'''s signature abilities are given to you and then some, at the cost of a bug that cuts your maximum HitPoints in half while it's set). This includes:

* Imagine a magic user being able to cast one specific spell whenever he likes, so long as said spell is on the second page of his spellbook and he's wearing three magic rings on one hand. That's the essence of the 11th Chip [[GoodBadBug Glitch]]. Initially, players are allowed to select from five chips per round. By earning or trading certain programs, players can boost this up to ten. With duplicates, players can quite literally boost their chip selection [[UpToEleven up to or past eleven]]. As the game only has 10 spaces, this results in a glitch which gives players unrestricted access to whatever chip happens to be in the second slot of their unshuffled folder.

* ''Battle Network 2'' is notorious for the Darkness (literally named DarkMessiah in Japan) PA (Bass V3 X + [=AntiNavi=] X + Any Gospel chip X), where Gospel appears and uses his dark breath on the front and middle columns of the enemy's side of the field. If anything survived the initial onslaught, Bass would attack the back column. The kicker? Both attacks did 3000 damage each. The first attack alone is enough to [[BeatThemAtTheirOwnGame kill the final boss himself in one hit]]-- and it pierces shields, so you don't even have to wait for him to open his mouth!

* The Toadman navi chip from the second game. Back then, you could have up to 5 of the same Navi chips, as long as you only have, at most 5(or 8 with some style) Navi chips in your folder. The Toadman chip stuns and tracks the target. Basically, you can spam them over and over again, and put in some combo extending chip in the middle of Toadman spam. Oh, and one of the chips from T code(Toadman's code) is Tornado variants.
* Snakeman from the second game. Easy to set up(some area grabbing, geddon for holes), massive damage especially after boost, and it doesn't give MercyInvincibility upon hitting. It is, alongside Gater is considered the easiest and cheapest folder to pick up and kill bosses.

** A similar glitch exists with Prism and Varsword. Basically, in 2, Varsword's shockwave is multiplied 5 times when it hits the prism. With some area locking, and timing, you can basically throw the prism, unleash the Varsword shockwave, and win against the boss without much effort.

** Don't forget Recycle -- it, too, can, in the right hands, become a GameBreaker. How so? It will literally recycle ANY Navi chip that was used last. That includes fellow Giga Chip Bass (which deals a truckload of damage and [[UselessUsefulSpell normally requires a special panel to exist for it to work]]), even if the Dark Hole that's needed to use the actual chip is nowhere to be found. Let's also not forget that it can also recycle any of the OTHER Navichips, essentially letting you use the same Navi chip TWICE (which is especially bad for your opponent if you happen to use a multi-hitter that they're weak to -- like [=BubbleMan=] or [=PlantMan=]). Even better, it keeps any bonuses you had when you used the first chip - e.g. Atk+30s.

** Speaking of BN 3, P code, E code, and F code. Basically, all three of those codes carries several variety of battlechips, including the ability to turn a battle into a complete stunlock. However, the E code stands out the most, thanks to its ridiculous versatility, and near invincible defensive chips.

** Of course, using enough Dark chips means your base max HP will be reduced to 1... But you can easily place a pair of HP+500 programs in your Navi Customizer to counteract this, as customized HP can't be permanently lost from Dark Chip usage.
* The light path perk in ''Battle Network 4'' is commonly considered to be the most broken passive effect in the entire series. Full Synchro, normally a status effect that is achieved through counter hits, doubles the attack power of your next chip. The light path perk gives you a rather high chance to enter Full Synchro with any successful attack, counter hit or not. This, when used along with chained multi-hit battlechips, can almost immediately destroy any boss that is not immune to being stunned. So broken that the perk was completely removed in the fifth game.

** In Battle Network 3, Variable Sword was an even bigger GameBreaker than its future counterpart. It only did 160 damage, but with the right button combo, this could be turned into four attacks, one in each element, which meant that if your opponent had any sort of elemental affinity, it would do an easy 800 damage (160 x 5) without boosts. And unlike Neo Variable Sword, this version was just a standard chip, meaning that you could have up to four copies of it in your folder.
** Variable Sword is considered the second most broken standard chip in [=BN3=]. The most broken goes to Sensor. What did it do? It put a Killer Eye in front of you that checks in a straight line had it been put on the middle line. If it hits, it does damage that pierces MercyInvincibility and stuns the victim, and the eye is active for a long time. It doesn't deal as much damage as Variable Sword did, but it forces you to stand on ONE row and being open to attack, or move and open to attack and with proper timing, it can even stunlock.
* Battle Network 2 is notorious for the Darkness (literally named DarkMessiah in Japan) PA (Bass V3 X + [=AntiNavi=] X + Any Gospel chip X), where Gospel appears and uses his dark breath on the front and middle columns of the enemy's side of the field. If anything survived the initial onslaught, Bass would attack the back column. The kicker? Both attacks did 3000 damage each. The first attack alone is enough to [[BeatThemAtTheirOwnGame kill the final boss himself in one hit]]-- and it pierces shields, so you don't even have to wait for him to open his mouth!

Strap yourself in, this is going to be loooooong.

* The Japanese version of ''[=EXE2=]'' also had a game-breaking glitch: Throwing a [=ForestBomb=] on a Prism would result in neither object disappearing after the hit; instead, the [=ForestBomb=] would repeatedly hit the Prism, which would then deflect the hit onto the surrounding 8 panels. This worked especially well on bosses. \

* In general, there are 2 chip that is the single most game changing chip in the entire series starting from the second game, First is Area Grab, which is a simple chip that took one row from opponent's field. Second, is Full Cust, which as the name imply instantly fills the custom gauge. The former allows you to control the field, and essentialy increases your winning chance by having more space to move, and how easy it is to score your attacks. The later is a simple, yet deadly tool for increasing your folder speed. Its especialy more prominent in the second game, where you can have FIVE of them in your folder, and sixth game that have the ridiculously powerful Beast Out.

* First game's Guts Shoot. Its easy to construct since it uses Guard and Dash attack alongside Gutsman, all a pretty common chip in their own right. It does 500 damage to one enemy on the row you are standing on. Consider that bosses tops at 1000 HP...
* Toadman navi chip from the second game. Back then, you can have up to 5 same Navi chips, as long as you only have, at most 5(or 8 with some style) Navi chip in your folder. Toadman chip stuns, and track the target. Basically, you can spam them over and over again, and put in some combo extending chip in the middle of Toadman spam. Oh, and one of the chips from T code(Toadman's code) is Tornado variants.
* Snakeman from the second game. Easy to set up(some area grabbing, geddon for holes), massive damage especially after boost, and it doesnt give MercyInvincibility upon hitting. It is, alongside Gater is considered the easiest and cheapest folder to pick up and kill bosses.

** A simmilar glitch exist, with Prism and Varsword. Basically, in 2, Varsword's shockwave is multiplied 5 times when it hit the prism. With some area locking, and timing, you can basicaly throw the prism, unleash the Varsword shockwave, and win against the boss without much effort.

** Speaking of BN 3, P code, E code, and F code. Basically, all three of those codes carries several variety of battlechip, including the ability to turn a battle into a whole stunlock hell. However, the E code stands out the most, thanks to its ridiculous versatility, and near invincible defensive chips.

*** You don't have to use Hub.BAT with an elemental Style, but without a Style you're limited on what other programs you can use. The advantage you had with 3 over 2 is increased extendability on Mega Man's abilities from the Navi Customizer. In 2, you were limited to what the style offered you.
