The Man Who Bought America: Part 4 Steven Rogers II (the Cap of the 1950s) continues to shake off the effects of Dr. Faustus as he presses his attack on the killer of his former partner Jack Monroe, the Bucky of the 1950s, who stands before him -- Bucky Barnes, the new Cap. As they fight Barnes continues to note that the 1950s Steve Rogers has obvious superior strength, speed and skill with each connecting punch and kick. But the 1950s Rogers is erratic in his fighting, which allows Barnes to at least keep his distance while Barnes attempts to catch his breathe and devise an effective counterattack. As the fight continues, Barnes changes his tactics to try to appeal to Rogers II's better nature. Barnes' tactic works temporarily as the 1950s slowly begins to break Fautsus' conditioning to seek retribution for Barnes killing Monroe in Barnes' former role as the Winter Soldier which Barnes admits to and begs for Rogers II's forgiveness.
