* CrowningMusicOfAwesome: So much that it has [[AwesomeMusic/NarutoClashOfNinja its own page]].
* GameBreaker: Several characters:
** From the second game to the [[NoExportForYou unlocalized third and fourth games]], Akamaru. Who, being a dog, is so short that everyone's attacks go over his head.
** Also exclusive to said games, Crow. While he doesn't have many great combos, he doesn't flinch when attacked, so he can freely interrupt enemies' combos and even have some of them that involve carrying their target into the air, miss entirely when done on him.
** Pre-TimeSkip Sasuke with the Sharingan has a strong attack (his upward one) which hits instantly and from across the map, with predictable results. He also has a regular combo which allows him to teleport behind his opponent and attack instantly, giving them no time to turn around and block. His normal version also had this move too, but it was a bit slower. It gets a bit worse with his ''Shippuden'' incarnation in ''Revolution 3'', where he can teleport during a jump instantly behind the opponent anytime he wishes; this carries over to ''Gekitou Ninja Taisen Special''. Expect this to be rather central to his gameplay, and nevermind that it cost a bit of chakra each use.
** Shino has his neutral strong (charged up) to down strong infinite combo that loops into itself over and over again, which can effectively trap targets for as long as possible so long as they don't fall for it beforehand.
** Kabuto regenerates most of any damage he takes, effectively giving him far more health than anyone in the game. His combos aren't bad, either. He also can reach VERY far with his neutral special attack, as his initial blow to start it (along with Tenten's) makes him lunge pretty damn far. It was fixed into a different initial blow since ''Revolution 3''.
** Itachi pre-''Revolution 3'' (in both Japanese and English version games) can spam his midair strong attack to rapidly drop clones on you for repeated pressure. He already has enough with his upward strong attack providing a similar effect as well (and that even leads into a combo). He gets a new midair strong attack in ''Revolution 3'' and ''Gekitou Ninja Taisen Special'' however.
** From ''Shippuden EX 3'', the stinger attack from Sasori's Hiruko form lets him break his opponent's guard in one shot from across the screen, his regular combos are almost as powerful, and his special attack poisons the opponent on top of its substantial damage.
** Anyone who can break guards with a single combo is, if not a GameBreaker, a [[GoddamnedBats Goddamned Bat]] at least.
** Hand Seals allow characters to get a boost in attack, defense or chakra, which only happens if you are using a Wii Remote + Nunchuk controller.
** A ton of characters from ''Shippuden: Gekitou Ninja Taisen EX 3'' had some broken Senzai Ninriki (Latent Ninja Powers) passives that had this in varying degrees:
*** Naruto's back strong attack which summoned his shadow clone no longer cost chakra, so most of the time opponents couldn't wait it out, or not even hit it either way to get rid of it (since they couldn't lock on to it like in a multiplayer battle). Temari could do this with one of her strong attacks that made her perform her summoning jutsu in the same vein as well.
*** Some characters, like Asuma and Sasuke (with Sharingan active) had one of their strong attacks unblockable while in said Ninriki State.
*** Kakashi is ironically a borderline case of the above, but is still game breaking; all of his moves took off a lot more on the opponent's guard gauge than usual, meaning he could guard crush as much as he wanted if he seized the momentum while in a pinch.
*** Yugao became a full on speed manic on all of her moves, making her hard to control but hard to pin down as well as making many of her basic combos very quick (though some combos wouldn't connect properly all the way).
*** Kabuto, as if he wasn't bad enough, now recovers health with every attack he lands, effectively giving him life steal.
*** Some characters' moves became doubled in their actions, like Shino's neutral strong attack and Kisame's Suikoudan no Jutsu down special (but costs 50% more chakra), and one of Sai's strong attacks made his artwork (the bird) fly back for a return strike after a set amount of time (which Kisame's case is much closer to). Deidara on the other hand could add 1 more clay spider bomb to his charged down strong. Guess what shenanigans it can lead to.
*** Hinata had her chakra [[LagCancel Lag Cancels]] have no cost at all, making them free at anytime. She could have juggles and frame lock combos for days in the hands of a skilled player.
*** Neji and Gaara could automatically have their back strong and down strong attacks (respectively) active as a passive that always works against any projectile, so campers or characters with an actual need to zone their opponents have a lot less of a chance against them, arguably enough.
*** Both Sasori and his Hiruko form could now poison the opponent with nearly any attack, though thankfully it doesn't stack. [[ButWaitTheresMore What's worse however]], [[InterfaceScrew your left and right controls are reversed while poisoned]], making things pure hell for you if you're not ready.
*** More of an annoying case than game breaking, hitting Hidan in his Ninriki state would make it so that you'd take a portion of the damage inflicted on him in return. Makes it a huge pain to even try to win against him with a perfect win round, as it was seemingly impossible. Though it could apply to some cases where against Hidan (like in a mission of some sort), you are to beat him without taking any damage, so welp...it was changed instead to give him complete Super/Hyper Armor during his downward strong attack to setup for his down super safely.
*** Just like Sakura's, Tsunade's allowed her to regenerate her HP; the kicker that makes it "more so"? ''[[UpToEleven She could stack it with the regen from her down special if it connects, healing nearly ALL OF HER HP in one go.]]''
*** It was bad enough that they reworked pretty much everyone's Latent Ninja Powers in ''Shippuden: Revolution 3''. Though some, like Nine-Tails Naruto now having SuperArmor, still stood up there. As well as others like true Sasori still being able to poison his opponent (but no longer reverses controls), Shikamaru's guard gauge never lowering, and some characters still keeping some of their old [=LNPs=] which may or may not be game breaking (but some like Sasori's and Asuma's were at least rebalanced however).
** While ''Clash of Ninja/Gekitou Ninja Taisen 1'' and ''2'' were decent fighters, they lacked depth in terms of value and combos. It wasn't until ''GNT 3'' [[NoExportForYou (which never came out of Japan)]] rolled around that the series was being taken more seriously, adding more than one special for each character and aerial throws. ''Gekitou Ninja Taisen 4'', being the last game on the Gamecube, is the one considered best known and played by most fans, as it had fixed all the issues from the previous games, had 40 characters to play, and introduced the all well known combo cancel system. However, [[https://www.youtube.com/watch?v=aAnXxXulY_E that game did have quite a few]] [[https://www.youtube.com/watch?v=9ZZKbdWqu00&hd=1 glitches]] [[https://www.youtube.com/watch?v=uszNV6oe2KA&hd=1 and bugs that were strange but at least fun...]]
** The ''GNT EX/Clash of Ninja Revolution'' games however, have caused a BrokenBase, as well as [[TheyChangedItNowItSucks They Changed It, Now It Sucks]].
** However, a lot of depth and overall complete overhauls to the characters occurred in ''Shippuden: Revolution 3'', as a ton of new moves (like some new specials, new throws and redone strong attacks) and mechanics (new functions for some of their signature moves) for the characters have been added, as well as moves that only cost a small portion of chakra no matter what (unlike most that only drain chakra when held down/delayed). However, the game was also sadly, known for its poor online play via Wifi, especially since ''Revolution 2'' had it completely removed.
*** Most if not all of these changes carried over for Japan in ''Shippuden: Gekitou Ninja Taisen Special''. ''Special'' also overhauled the tag-team system with a new bar solely for substitutions, separate from the main chakra bar; much like the recent and upcoming competitive Naruto games. They also allowed for the Classic and Gamecube controllers to also power up special attacks much like the Wii + Nunchuck combo.
** In ''Revolution 3'', earning money to buy things is a ''chore''.
** Hand seals have gained this. Introduced in ''GNT EX 2'', players who used the Wii Remote/Nunchuk were given the chance to perform a certain motion control that can give a small burst of chakra, or boost defense/attack power. The problem? This mechanic is not ''available'' for ''Gamecube or Classic Controller players''. TOMY's solution in ''Clash of Ninja Revolution 2'' is the ability to turn it off for tournament players. However, in ''Revolution 3'', if you play a match against the AI or an online match, they still can use it against you. Of course, most of the mechanics that work only for the Wii Remote + Nunchuk combination tend to be this anyway, since none of the other controller schemes can make use of them. As an inverse, you can't even charge up back weak attacks/autoguard moves with the nunchuk, while with any button-central-scheme you can. However, in ''Special'', it's now possible to power up special attacks with the motions through the use of the Classic and Gamecube controller schemes.
** In ''Revolution 2'', Asuma, with his quick movements and the fact you're playing a character who's fairly weak, makes him a problem.
** Kabuto, in the same game, is even worse during a certain story mode battle: recovers health, doesn't flinch, and you have to finish him with a special, which is ''very'' hard.
** ''Revolution 3'' has Deidara, who doesn't recover, but carries the non-flinching effect, and can one-hit KO if not careful. What makes it even more of a problem is that you're forced to play as Naruto in this Nine-Tails state. You have to defeat a zoner with a ''rushdown'' character.
** Few, if any, expected Yugao Uzuki, a character who ''barely'' appeared in the manga and anime, as a character in these games.
** Then comes the Fourth Hokage, AKA Minato Namikaze, in ''Special''.
* WTHCastingAgency: In ''Taisen Special'', Sage Naruto is a playable character and Jiraiya's special attack was changed from the Toad Flame Bomb from previous games to a new attack where he goes Sage Mode and uses the Massive Rasengan. Considering also that Bee and A are playable and Sasuke is his Kage Summit incarnation here, this game obviously goes past the Pain arc. Despite that, neither Pain nor Konan are playable characters. Oddly enough, one battle in Jiraiya's story mode is a 1-on-3 fight in the Akatsuki Hideout stage against Akatsuki members that are references to Pain's Paths, them being Deidara[[note]]Who stands for the Animal Path given his ponytail and summoning clay bombs in the shape of animals, mirroring the Animal Path's summons[[/note]], Sasori[[note]]Who, as a puppet filled with weaponry, stands for the Asura Path, who fights in a similar way[[/note]], and Hidan[[note]]Whose curse abilities mirror the Ghost Path's ability to remove one's soul, both of with are an instant kill, as well as Hidan having a black pike as a weapon much like the rods used by all Six Paths of Pain[[/note]].
