Episode 4: You Were My Hero

Mark asks Rudy to analyze the drone, which he determines originated from Earth and was created by someone with vast resources. Mark confronts Cecil, believing he built it, but Cecil denies it. Later, while on a date with Eve, Fightmaster and Dropkick forcibly recruit Mark and bring him to their future, believing he can save their Earth from its tyrannical king, the Immortal. Driven mad by his immense power and immortality, he blames Mark for his eventual abandonment of Earth and demands he fight him to the death to bring him peace. Reluctantly, Mark fights and is eventually forced to kill the Immortal. Returning to the present, a shaken Mark finds solace with Eve. Meanwhile, Nolan faces execution until Allen breaks free, liberates their fellow inmates, gains Battle Beast's help in fending off the Viltrumites, and feigns defeat to spur Nolan into action. After breaking out, Allen suggests they flee before reinforcements arrive, but Nolan reveals the Viltrum Empire now consists of fewer than fifty pure-blooded members.
