-->1444. My Ally advantage and Arch Enemy flaw can't both represent the same person.
* ''TabletopGame/{{Warhammer 40000}}'' example: Leman Russ and Lion El'Johnson hated each other's guts for quite some time after their first encounter, in which the two primarchs ended up fighting each other over an honor issue, fueled by their [[BoisterousBruiser vastly]] [[TheStoic different]] personalities, but over time, they became accustomed to each other's personalities and eventually became very close friends. Their rivalries remained, however, so this is the kind of friendship that evolved. Their successors sadly only remember the rivalry part of their relationship, however.
* The ''TabletopGame/DungeonsAndDragons 3.5'' iconics Jozan and Lidda straddle the line between this and WithFriendsLikeThese. She gets irritated by his pious and saintly straitlaced GoodShepherd ways, and he gets irritated by her unrepentant LoveableRogue ways and love of constant teasing, to the point of near-constant {{Snark To Snark|Combat}}[=/=]PassiveAggressiveCombat. ''But'' they'll still risk their lives for each other, and at one point Jozan admits to Regdar during a battle that he wouldn't mind having Lidda around to help. D'aww. No doubt they'd then start arguing again afterwards...
* In ''TabletopGame/ChuubosMarvelousWishGrantingEngine'', Leonardo has this relationship with almost everyone, but ''especially'' Chuubo, to the point where his playbook actually ''crosses out'' his Connection 2 because he has ''absolutely no connection to the wretched child at all''. Of course, when one of your powers is literally fuelled by your desperate need for and complete inability to express or deal with friendship, this is probably inevitable.
