Besides the {{Conflict}} between the protagonist and antagonist/situation, the most common form of conflict is between allies. It would not only take away the suspense, but also the depth, to have everyone on one side working as one, with no problems. Thus the heroes and the villains have conflict with each other, and the side that usually wins is the first to OvercomeTheirDifferences.

This isn't always easy to pull off. Done wrong it looks like the writers are just handing out {{Conflict Ball}}s. Or it's so {{Anvilicious}} the drama is undermined.

The difference can be between allies, between friends, between leaders and subordinates, between lovers or between those who are falling in love.

But it's still essential in many stories. It looks all the more triumphant for the winning side to get past such a major obstacle. This is especially true when the differences are the antagonist of the story instead of a person, such as in many romantic comedies, and every BuddyCopShow and movie.

!!Examples:
* ''RatchetAndClank'' both played this straight in the first game and Lampshaded it in the "Secret Agent Clank" level in ''Up Your Arsenal''.
* The term was used in TheFilmOfTheSeries of ''Film/WildWildWest'', but these differences came across as [[{{Anvilicious}} way too obvious]].
* Anak and Hatsu from ''Webcomic/TowerOfGod''. At least it appears so at first, but one is still a loose cannon and the other a condescending stick in the mud.
* The love interest variant is mentioned in item 98 in the EvilOverlordList.
** "If an attractive young couple enters my realm, I will carefully monitor their activities. If I find they are happy and affectionate, I will ignore them. However if circumstance have forced them together against their will and they [[SlapSlapKiss spend all their time bickering and criticizing each other except during the intermittent occasions when they are saving each other's lives]] at which point there are hints of [[{{UST}} sexual tension]], I will immediately order their execution."
* WesternAnimation/WallE and M-O, in a very [[TearJerker emotional]] scene.
* The basis beyond several ''WesternAnimation/TeenTitans'' episodes such as "Divide and Conquer", "Forces of Nature", and "Switched".
* ''Series/TheXFiles'': [[AgentMulder Agents Mulder]] and [[AgentScully Scully]], FBIAgent!!
* A prevalent theme in DubiousCompany. Just about any character pairing will need to do this to [[BigDamnHeroes save the day]] or help each other TakeALevelInBadass. [[StraightManAndWiseGuy Tiren and Walter]], [[SensitiveGuyAndManlyMan Elly and Walter]], [[BrainsAndBrawn Sal and Tiren]], [[RedOniBlueOni Leeroy and Sal]], [[SwordAndSorcerer Marty and Gary]], [[TomboyAndGirlyGirl Sue and Mary]], [[HarmonyVersusDiscipline Marty and Sue]], [[EmotionsVsStoicism Mary and Gary]], & [[InterserviceRivalry Walter and Izor]] are the most reoccuring examples.
* Done beautifully with Kristina and Ulrika in ''Literature/TheEmigrants''.
