X-Men—all that mutant power in one place. Suicide Squad is going down. Poor Captain Boomerang—without any superhuman abilities—just standing there tossing boomerangs. He'll be the first one down.

sorry babe, but to me the squad would win hands down. their leader is ruthless, and they wouldn't be concerned about preserving life, including their own. kamakazi warriors! and captain boomerang may be silly, but he is very mean!
