시즌 1, 에피소드 4: Tony Stark is backing a charity racing event in order to burnish the image of Stark Industries. He explains to Dr. Chika Tanaka how his encounter with Dr. Yinsen after being captured by guerillas changed his outlook on life and inspired him to work for world peace. Meanwhile, Kawashima, a race car driver who’s suffered career-threatening injuries, is won over by A.I.M./Zodiac who promise him they will heal his injuries if he takes out Tony Stark. When Tony makes an appearance at the race track, Kawashima tries to kill him with a test car but Logan, the mutant X-Man known as WOLVERINE, shows up in just in the nick of time to save him. Later, Logan gives Tony some info on A.I.M and together, they track Kawashima down and find him operating the Zodiac killer Mech, TAURUS. After Iron Man frees him, the rogue Dio arrives and Iron Man must do battle with his own creation, wondering all the while who it could be in the armor.
