History TeethClenchedTeamwork / AnimeAndManga

* ''Manga/CardCaptorSakura'': Sakura and Syaoran's initial relationship starts out as such, primarily because Syaoran is convinced that he is entitled to the Clow Cards and that Sakura is a pathetic weakling who's out of her league.

* In ''Manga/DetectiveConan'', Chianti and Korn ''really'' despise [[ChronicBackstabbingDisorder Vermouth]], but when their superiors from [[TheSyndicate the Black Organisation]] say so, they work together.

** Fellow Supernovas Eustass Kid and Trafalgar don't get along, often slinging at insults at each other, but more than once have fought alongside each other, as well as Luffy, [[EnemyMine against common enemies]]. Despite their mutual disdain, they're good enough of a team to [[spoiler:defeat Big Mom, one of the Four Emperors of the Sea]].

** In the anime, Roy and Ed [[TheRival live this trope]]. Over time, the relationship goes from trying to manipulate each other to "I still don't like you but I ''do'' respect you." Envy tries to use [[DudeLooksLikeALady his/her/]][[AmbiguousGender its]] tried-and-true ShapeshifterGuiltTrip on Edward. When he turns into Roy, Edward briefly hesitates and then smiles and says "You couldn't have picked a better target!"

** Ichigo and Ishida's initial rivalry ends when a [[GiantMook Menos Grande]] appears. This leads to TeethClenchedTeamwork against the mountain of Hollows they're surrounded by and is the beginning of a FireForgedFriends.

** [[PredecessorVillain The Rocks Pirates]] were one of the most powerful pirate crews of all time, to the point that the Navy was forced to work with [[spoiler:''Gol D. Roger'']] to take their leader down. Their one weakness? The entire crew -- which included such figures as Whitebeard, Kaido and Big Mom -- '''hated''' each other. Their aforementioned leader was the only one able to make them stop trying to kill each other and work together as a team, and [[KeystoneArmy once he was gone, the crew immediately split up]].

** This happens commonly whenever Yuma has to team up with someone in a tag duel, as he and his partner often struggle to develop a sense of teamwork, as seen with Shark, Kaito and Anna. Ironically, Yuma has less trouble displaying teamwork when he's paired up with a villain (Girag and Vector, respectively), due to the fact that he's kept in the dark of their true nature.

* ''Anime/YuGiOhArcV'': A more realistic version is between Gongenzaka and Sawatari. When they team up against Kaito, Sawatari doesn't get the memo that Gongenzaka is trying to force Kaito into a peaceful negotiation, completely ruining Gongenzaka's attempt at keeping peace. When the two of them are forced into a Tag Duel against the Tyler Sisters, their decks are 100% incompatible with each other, resulting in them losing off-screen to the sisters. To elaborate how incompatible their two decks are: Gongenzaka's Superheavy Samurai deck relies on having no Spell or Trap Cards in his Graveyard, as otherwise his deck would cease to function. Sawatari's Abyss Actor deck, on the other, heavily relies on Normal Spell Cards or else his strategy cannot work because his monsters can't do things on their own due to their rather passive nature. Since Tag Duels force teammates to share the same field, Graveyard and Life Points, Gongenzaka in particular cannot play properly under such conditions.

** Kotori and Cathy normally can't stand each other, so they naturally end up losing all of their duels in Girag's Sports Day Tournament. When the final match is decided and Kotori and Cathy are set to appear, Girag brainwashes them, which also happens to be the only way for them to not go under each others' throats.
