[General superheroes] Out of the heroes who regularly work as part of a team, who is considered to be the worst or most difficult to work with?

Basically the title. The general consensus seems to be someone like Spiderman is the best to work with and is generally well liked, but which hero is regularly part of team lineups despite being hard to work with at the best of times?

Alternatively, which heroes on the teams are good to work with because they can handle themselves when the chips are down, but are disliked because of their personality?

Batman is often accused of mushroom management: keep them in the dark and shit on them. In many iterations, he's paranoid, keeps everyone at arm's length, and always has ulterior motives. Less so recently, but this if often his characterization.

Deadpool often finds himself on teams, and nobody's happy about that, because, well, Deadpool.

Tony Stark is often an egomaniac, and some of the stuff he's done in the comics borders on super villain territory.

Reed Richards is kind of a dick. Really, the whole Illuminati are pretty bad at playing nice.

But the absolute *worst* person to be on a team with is probably Amanda Waller, because she will blackmail you into doing what she wants, and has no remorse about sending you to your death if it makes some other task slightly easier for her. She is wholly amoral, and will cross pretty much any line, burn any bridge, and sacrifice any life if it gets the job done.
