Rich Man: Iron Man--Power Man: Thief!
The code-name "POWER MAN" has its origins in the term "BLACK POWER" Luke decides to call himself that when Orville is surprised that he managed to break into his escape vehicle, and Cage responds, "Just chalk it up to Black Power, Man!"
Synopsis:
Angry that other superheroes get all the headlines, while he doesn't get so much as a mention, Luke Cage decides that perhaps he should adopt a superhero name to put him in the same field as Captain America and Spider-Man. That day Luke is approached by a gentleman named Orville Smythe, who claims to be an employee of Stark Industries and has come to hire him to test out the security in place at the Stark Industries building. Cage is instructed to try to break into Stark Industries and steal an experimental suit of armor built for deep-space exploration.
Luke agrees to the job and starts by breaking into Stark Industries. Luke can deal with most of the security in place until Iron Man enters and battles Luke one-on-one. During their fight, Luke learns from Iron Man that Orville Smythe is not an employee of Stark Industries. Realizing that he's been tricked, Luke teams up with Iron Man to track down Orville, who has succeeded in stealing the armor and a ship to escape in. Chasing after Smythe on the ship, he confronts his foe. During the fight, Orville is accidentally kicked out of the ship and plummets to death. After, Luke returns the ship to Stark Industries, where he bids Iron Man farewell and tells him to address him under his new name: POWER MAN.
