Captain America runs the Slugfest gauntlet...
Captain America runs the following Slugfest gauntlet (which is identical to a Slap-off, but with punching instead) with all matches lasting until one side is either KO'ed or dies...
Each contestant must stand completely still and tank a punch to the face (no hitting in the throat allowed) with nothing more than natural durability; bracing is allowed, but shielding, gadgets, intangibility, and any other form of damage negation is prohibited...
Captain America is allowed no rest or recovery time inbetween opponents; as soon as one round ends, the next begins immediately...
Captain America's opponents get the 1st punch in in every fight and it alternates from there (opponent, Cap, opponent, Cap, ect, ect)...
Now that the ground rules are set, how far does Captain America get?
1) Kingpin (Netflix)...
2) Spock (Into Darkness)...
3) Khan (Into Darkness)...
4) Marv (Sin City)...
5) Spiderman (Civil War)...
