Synopsis:
The Black Knight: Tony Stark suffers another attack on his heart just as the Black Knight arrives to trash Stark's factory and draw out Iron Man, seeking revenge on the Avengers. Tony locks himself in his office, quickly adding extra energy packs to the Iron Man armor in order to sustain his heart. Pepper and Happy, concerned for their boss, attempt to break in while Iron Man battles the Black Knight. Happy becomes a target, but Iron Man defeats the villain by flipping his horse's hooves, unseating him. Worst of all, Tony discovers that his body now relies on the full suit of armor to survive, meaning he must wear it full-time or die.
Captain America: A quiet evening on watch for Captain America turns into a brawl when thieves break into Avengers Mansion. Though they manage to tie him up, Cap defeats Bull Brogin and his gang single-handedly, proving his unmatched combat skill.
