History
The Oni Queen was a robot created by Mojo, and modeled after the make-believe villain conceived by an Earth kid named Bobby for a play-pretend scenario that he was enacting with his mother, in which he was a hero named the Iron Shogun. After kidnapping Bobby's mother, Mojo brought Bobby's fantasy to life, and Iron Man infiltrated it to rescue her, portraying the Iron Shogun.
Bobby's script took Tony to the Oni Queen, who was holding Bobby's mother hostage. Back home, at this point in this story, Bobby's mother had broken away from the story, lunging at his son to tickle him. In Mojoworld, she took the cue that Iron Man was following the script, so she similarly broke away from it by leaping at Iron Man as he intended her to do, much to the robotic Oni Queen's confusion. With War Machine's help, Iron Man and Bobby's mother then escaped back to Earth.[1]
