10 Former Justice League Members Who Need Another Call-Up
5. Captain Atom
Captain Atom, right now, would make for a very interesting addition to the team.
Recently being presented with more interesting quantum based abilities, there's really one thing that would make Captain Atom so interesting to see on the Justice League now: Doctor Manhattan.
Doctor Manhattan was basically created as an analogue for Captain Atom back in Watchmen; now, Manhattan has come to the DC Universe proper, which poses a really intriguing question: how intriguing would it be to see Doctor Manhattan stand up to Captain Atom? Oddly enough, the Captain may be the one most likely to be able to make a stand against him.
Add to that the fact that Captain Atom has more of a military background, which could potentially bring him into conflict with his unregimented League teammates.
