4. Master of Various Martial Arts
Captain America is one of the strongest hand-to-hand combatants. Due to his military training under private trainers, he is a master in judo, boxing, jujitsu, Okinawa-te, Defendu and other various gymnastic abilities. Moreover, these skills pretty much go with his suit’s flexibility and elasticity.
5. Super Strong Will
Just as he is rock-string physically, he has a strong will to control his temptations and handle emotional struggles. He can resist him from getting affected by drugs and extreme pain. So only highly strong-willed people can try to influence him.
