Wade is possibly the only character where 

"What do you bring to the squad?" 

"Nothing, but the players wanted me here." 

would work as a valid justification for him being part of the squad.

I'm just thinking about what characters I want to play, but most of them hinge on someone else's choice in character, such as The Flash or Suicide Squad, per the rules.
