Shuffle a copy of Arch-Frenemies into your deck.
Emergents lead complicated lives. If you can run faster than a speeding racecar, bench-press a bus, or shape fire and ice into monstrous automatons, it's hard to relate to regular people. So most of them have to turn to others of their own kind for companionship, even if that means crossing lines of affiliation. This can lead to fluid love-hate-save-kill relationships between members of different crime-fighting teams.
