Captain America does NOT have his shield.
Bonus-1) If I threw in US Agent for the Rejected Supervillain Group, could Captain America still win? (US Agent has his shield)
Bonus-2) If Armless Tiger Man grew arms and Crazy Quilt had an AK-47 instead of a pistol?
Bonus-3) If Captain America was drugged before the battle to be less concentrated and weaker?
