The figure of Batman was horrified to realize he was in big trouble. "Give that rock back to me Freddie. It's mine." He said, while reaching for what he hoped was some weapon in his utility belt.
"Sorry Mr. Batman. I wish you'd only do what I wanted you to do." Freddy replied smugly.
Mikey/Batman froze. "That's better." Freddy smiled, "Say, that's a great power you've got to change shape and all, but I don't like looking at Batman, turn into Wonder Woman instead."
Instantly Batman's form was replaced by that of the buxom Wonder Woman.
"Ha ha, that's great. How do you feel Mikey?"
"Weird!" And Mikey turned around to look at the stunning woman in the mirror cupping his/her boobies. "Please let me go Freddie."
"Call me master from now on Mikey. We're going to have a lot of fun together you know.
"Yes master." Mikey responded automatically.
