History GameBreaker / ShinMegamiTensei

** Odin's Thunder Reign attack is a Severe-level, all-targeting Thunder skill...that costs only 22 MP. To compare, Maziodyne is one tier lower, also targets everyone on the enemy team, and costs 32 MP. While Odin himself has a pretty bad Magic stat, Thunder Reign can be passed on either via Demon Whisper if you have a high Magic stat, or to a new, magic-oriented demon via fusion.[[/folder]]

* In , Lucifer and Satan had a spell, "Alpha & Omega" which ''skipped the damage numbers'' and just wipes out the enemy party. Only two bosses in the game actually had some sort of countermove for it. One is an enemy that is immune to all attacks until you remove its barrier, and the other is Philemon, who will reflect the attack on YOU and cause a TotalPartyKill.

** Yoshitsune is the best physical attacker in the game because of his Hassou Tobi attack. Eight separate hits, though with light damage, casually offset severe damage like Primal Force. And it hits all targets to boot. Power Charged Hassou Tobi DOUBLES the damage output of a Power Charged Primal Force, the second-strongest physical attack in the game. Not to mention no weaknesses, and Yoshitsune is one of the most customizable Persona in the game (he only needs Power Charge and Hassou Tobi, and you can technically get Power Charge off of a slave), meaning you can have a semi-invincible god slaughtering the field.

** It was nerfed in the sequel, a little--Lucifer (now Helel) no longer learns Victory Cry naturally, and one might argue that it can be a pain to get it on the fusion components.
*** What!? Lucifer is still in the game, part of the Judgment arcana now though. And he IS a fusion component for Helel, meaning it is '''absurdly''' easy to get Victory Cry on Helel, thus becoming an unstoppable snowball once again.

*** However, ''Portable'' brought a new Game Breaker to the table: Skill Cards. Think TM's from ''Pokémon'', only 1) you can easily farm them and 2) there are no restrictions to what persona can learn what skill from cards. This means you can get personas with skills that they couldn't have through fusion (ex a Fire type casting Bufu spells). While it doesn't have the unique, superpowerful skills (Morning Star, Black Viper, Die For Me, Thunder Reign, Ragnarok, stuff like that), it ''does'' have the "Absorb ''x attribute''" skills. This makes it ''trivially'' easy to cover up weaknesses in strong personae. This can be taken to NighInvulnerable levels with a Beelzebub that essentially Blocks, Absorbs or Repels every attribute (and still have slots for attacks!).
**** Also of note: Skill Cards ''can be reproduced for no cost''. The Inari Sushi in the temple can take one card and make a copy of it after a few days. If you religiously go there every time he finishes, you can load up on very powerful skills you can put on any Persona you want.

*** In fact, let's just say that [=P3P=] is GameBreaker incarnate. It's practically the perfect game for SMT beginners, even excluding the two Easy modes.

* ''FES'' Also brings the MC's ultimate persona: Orpheus Telos. This palette swap of your original persona is clearly specifically designed for the BonusBoss because it resists everything but Almighty and Poison (The BonusBoss will automatically kill you if your persona absorbs or repels any of her attacks, so resist is the best possible option) and has great stats. The only spell that it learns naturally is Victory Cry, but most importantly, it can inherit ''every skill in the game.'' If you plan everything out right, you can have a single persona with the eight best attacks in the game. Mix and match to your hearts content to decide what eight skill combination is right for you. The catch? He can inherit '''''every''' skill in the game,'' not just the best ones, and because he has an equal likelihood to inherit every skill, you'll spend hours wading through combinations with inferior skills, hoping for that one-in-a-million perfect combination that you just spent a few hours setting up. Of course, this is all assuming that you maxed out every social link in the game, have the necessary fusion fodder, and are above level 90; the requirements for being able to fuse Orpheus Telos.

** Trumpeter, on the other hand, starts off Immune to Dark, Reflecting Light and Electricity, and Absorbing Ice. As a Hexagon fusion, it is moderately easy to get the other three immunities, giving you a person immune to everything except Almighty and Poison. On top of that, Trumpeter gets the best buff and debuff spells and the strongest non-unique Almighty spell automatically. And you can get Spell Master on it for spamming Megidolaons all day (use Skadi to fuse Daisoujou, one of the components for Trumpeter - accidentally Daisoujou with Spell Master borders on a GameBreaker by itself, as this makes its Light-based unique skill Samsara spammable and with Hama Boost Samsara has about 99% chance of instakilling anything not resistant to Light, while useless against bosses this allows to easily and MP-efficiently clear lots of normally-annoying encounters). Unlike Lucifer and Yoshitsune, which require some dedicated grinding, Trumpeter is fusable at about the level you'll either naturally be or are recommended to gring to (depending on difficulty-based EXP gains) before the final run of the Normal ending.
** What happened to Yoshitsune? Power Charged Hassou Tobi DOUBLES the damage output of a Power Charged Primal Force, the second-strongest physical attack in the game. Not to mention no weaknesses, and Yoshitsune is one of the most customizable Persona in the game (he only needs Power Charge and Hassou Tobi, and you can technically get Power Charge off of a slave), meaning you can have a semi-invincible god slaughtering the field.

** Beelzebub in ''Persona 4'' is the ultimate tank Persona. As long as you give it something to counter physical attacks, then the only thing it won't absorb, nullify, or reflect is wind and light.
*** Granted, it's possible to get Null Light and Repel Wind on him, thus making you immune to all damage that isn't Almighty.
** Metatron can do the same thing as Beelzebub but is a little bit harder to pull off.

* In Golden to add some AntiFrustrationFeatures, you're allowed to choose what kind of skills your Persona inherits. All the aforementioned GameBreaker stuff listed up above? Oh boy...

**** Vile and Dragon do come with a drawback though, of making your character wait longer between turns and reducing your Move (Viles have a higher attack range, but make you even slower). Still, that's not a big deal when you can attack twice in a row without ever being hit back, pretty much decimating whatever you're attacking.
**** In ''VideoGame/DevilSurvivor2'' higher level Dragons get Evil Flow. One usage of this buffs your attack range to 6, allowing the player to attack anything shy of a few bosses with complete impunity.

** The skill giving item. Oh gosh the skill giving item. Simmilar to UpdatedRerelease of Persona3 this allows you to give skills to your demon, except your option in this game is limited to some exclusive moves instead of almost every moves in the game. The catch? One of these items that is alvailable pretty early gives you 8 randomly hitting move that is alvailable to pretty much every demon in the game with fairly strong base power and sometime extra effect. This basicaly renders every other move barring healing move completely obsolete since you can spam this move to win any kind of fight. Combine with the fusion system above and even the BonusBoss wont last more than one round.

** Aigis' Orgia Mode when it comes to facing bosses and/or F.O.Es. A damage multiplier for only two turns doesn't sound impressive, ''on it's own''. However, the thing that makes it so unfair to bosses is that it doesn't take up a buff slot[[labelnote:*]]Only three buffs and debuffs can be applied to a unit during battle, with newer ones overriding older ones[[/labelnote]], meaning you can have that, Shura Tensei[[labelnote:*]]Greatly multiplies damage in exchange for losing half of your max health every turn unless canceled by Shura Revert or getting KOed, and ''it doesn't take a buff slot too!''[[/labelnote]], Heat Riser, Matarukaja AND Power Charge active for an even more powerful multi-hitting attack such as Danse Macabre on a thoroughly debuffed and preferably agility-bound enemy. Alternatively, having Rise as your battle navigator can turn that particular combination of Aigis into one of the best Linkers due to spotlight, and with the right passive skills, every successful follow-up attack will deal damage in the '''thousands'''.

* ''PersonaQ'', in addition to the expected game breakers, has three things that really stand out.

** The biggest game breaker has to be Naoto, however. Naoto is the only character who naturally learns both AOE OneHitKill spell lines. She also has very high agility (ensuring she goes before enemies), and very high luck (Which affects the accuracy of her instant death spells, and also allows her to get critical hits when she attacks). Equipping her with a Persona that knows "Impure Reach" (which boosts the effectiveness of status effects and instant death spells) allows her to easily sweep most random encounters on her own. In addition, the fact that bosses aren't immune to most standard status effects means that she's effective from the moment she can join your party through the end of the game.

** The MissionControl characters TookALevelInBadass upon coming to the Margin World, thanks to the Sub-Persona system. Unlike the combatant characters (who rely on a limited pool of SP to use magic), Fuuka and Rise instead rely on regenerating "Leader" gauge that builds as you fight shadows. This makes Fuuka one of the most efficient healers in the game, as she can grant the party three turns of recurring healing for only one 1/5th of the gauge. Equip her with a Sub-Persona like Kayuga and she easily outshines dedicated healers like Yukiko, Yukari, and Rei.
** Physically-oriented characters like Kanji, Chie, Aegis, Shinjiro, and Akihiko are highly valued because of the fact that most of their abilities are CastFromHitPoints, which (thanks to Fuuka) are easily replenished. One of the most popular strategies involves equipping one of these characters with a Sub-Persona that has several of the various "Link" skills equipped, which allow them to add bonus elemental damage to every allied attack that comes after them. Kanji is a popular choice for this, as he has the highest natural strength score and naturally learns abilities that allow him to go first in battle, allowing him to maximize link damage.

This palette swap of your original persona is clearly specifically designed for the BonusBoss because it resists everything but Almighty and Poison (The BonusBoss will automatically kill you if your persona absorbs or repels any of her attacks, so resist is the best possible option) and has great stats.

*** Why would you want to decimate, taking out one demon? Use it to straight up destroy. Although, if you really want to decimate, Multi-Hit would work better.

[[AC:Revelations]]
* Lucifer came very close; he had 999 or 99 in all stats, some of the strongest Dark skills, was immune to everything, and had the strongest earth skill. However, he was completely useless against dark demons as he had no light skills, so anything that reflected light would kill his host (always Reiji/Chris). [[note]]Adding a light skill through Tablets would circumvent this problem, however.[[/note]] Instead, the real GameBreaker was Abracab; it had the strongest light skills, the strongest healing skill, and the generally brilliant Boss Damage. That's not the best part, however; the real fun was BiStrike, which did damage equal to twice the user's HP. If your level is high enough to summon Abracab, your HP will be so high that nothing will be able to stand up to BiStrike. But you need revive magic, of course, which costs a lot of MP... actually, that's not an issue for two reasons. First, MP cost is calculated by the Persona, not the skill, and skills could be added to a Persona that didn't learn them naturally, meaning you could abuse the system and, in theory, get a Persona with a single-digit MP cost that had ReviveMore. Second, dead characters are revived with 1HP after the battle ends, meaning that all that's needed is healing and, if you're able to summon Abracab, you've probably found enough Spell Cards and got a high enough level that you have something with Elixir All (possibly for a low MP cost, as previously stated) By the way, Abracab himself has Elixir All, and since the dead character will be revived, he or she can then use Elixir All on him or herself, making Abracab 100% ridiculous.

** Odin's Thunder Reign attack is a Severe-level, all-targeting Thunder skill...that costs only 20 MP. To compare, Maziodyne is one tier lower and costs 32 MP. While Odin himself has a pretty bad Magic stat, Thunder Reign can be passed on either via Demon Whisper if you have a high Magic stat, or to a new, magic-oriented demon via fusion.[[/folder]]

** Focus: Raises the damage of the next physical attack by around +150%, and can be learned as early as lv23. It's not hard at all to hit 4 digits as early as against [[ThatOneBoss Matador]], or 5 digits later in the game due to this.

* Also in ''VideoGame/ShinMegamTenseiI'', one of the best swords in the game, the Hinokagutsuchi, can be acquired about halfway through if you know the proper fusions. One attack is usually enough to kill anything short of the final boss and his lackeys.

** Titania in Devil Survivor 2 is immune to all elements except curse and physical. By fusing her with physical repel and null curse, she becomes immune to everything except almighty attacks, which are rarely used.

** Freikugel: Almighty damage, stupidly high critical chance, absurdly high damage output. It's simply the strongest damage skill in the game.
