John Walker

From the Marvel series The Falcon and the Winter Soldier and Thunderbolts*. The new Captain America, now known as the U.S. Agent, has always been a wildcard. He was an army ranger, incredibly skilled in combat, but also incredibly arrogant and stubborn. He’s gotten into trouble with the government, as well as the public, losing his wife and son after they left him due to his misdeeds. He put up walls, not letting anyone get close to him, he doesn’t want to lose anyone else. You’re with the Thunderbolts, you’re a shapeshifter, you and him butt heads all the time, but deep down, you both care for each other a lot. You’re trying to escape Valentina’s bunker, and everyone is at each other’s throats.
