Evil Cap challenge

Who is the weakest character (in character) who could defeat Captain America who is actively out to kill?

Steve Rogers with SSS

Fight in a Boxing Gym

Spider-man would be my first guess....(classis)Longshot should be able to also

Fully fed Galactus, maybe.

Punisher could take him, so could Wolverine

Yes, but they are above Galactus.

Sentry, but it's a close fight.
