I like it when that happens. Sure, real teamwork is great, but it almost never happens. It's either one on one battles, or a swirling melee where nobody bothers to use any of their cool powers. Or worse, it's an OP villain destroying everyone while they forget they even have powers.
So I accept a series of 1v1 battles being the next best thing.
Unless...you know...there's like 20 in a row...
...fucking Bleach...
