I would say Deathstroke but it depends because Deadpool is inconsistent, sometimes he is above Wolverine and others and sometimes he is on the tier as Daredevil. Deathstroke can give in good days even Wonder Woman, Aquaman, The Flash or Green Lantern a good fight. In his new comic series he is really powerful and young again.
No chance for Bane. He is not as strong, fast, and he can't fly. Plus, Goku would only need a weak energy blast (not much effort/time to fire) to explode Bane into smithereens. Even if he tried to break Goku's back, it would do no damage whatsoever.
The only thing that longshot has on captain america is his telepathy, as captain america is far better than any human in every other regard. Captain america has the will to conquer most telepaths. Winner is captain america
Pym is Scientist supreme for a reason. His achievements surpass petes. Reed has made armor to combat galactus. Once Pete has feats on that level he can be in the conversation for one of the top 5 most intelligent men in marvel. But Feats>Character statements. The Intelligencia didn't even put Pete in top 8. They didn't even take him lol. They're whole deal was taking the smartest men on earth and Pete wasn't even a Target. Pete has great potential. But we can only judge based on what a character had actually accomplished. Not what they may be able to one day.
