Uncanny X-Men #197 - Dr. Doom hotsell

Back at Murderworld, Colossus and Shadow Cat enter a part of the amusement park of death modeled after New York City circa World War II. When they are attacked by a subway train that transforms into a robot, Arcade lends the two mutants a hand by sending in an army of X-Men robots to help destroy the device. They are strafed by a craft seemingly carrying Dr. Doom, the apparent attacker. Colossus incapacitates the ship and then tosses Kitty at it so that she can phase inside as it crashes. It unfortunately crashes through the Arcade's control room. When Colossus gets there it appears as though Doom has killed Kitty; however it turns out to be only a robot duplicate of her and the real Shadow Cat shorts out "Doom's" armor. With their foe defeated it turns out to be Arcade's assistant hotsell Miss Locke. Arcade explains that every year on his birthday he allows Miss Locke the opportunity to try and kill him over the course of 24 hours and he must do whatever he can to prevent it.
