Iggy was born A Long Time Ago in a Galaxy Far Far Away. He walked to here, and decided he liked Oxygen better. So, he started breathing oxygen. He eventually developed shape shifting abilities, and he turned from alien to human. He was mad that his new form smelled, but other than that, he didn't really mind it.
He lived here for several years, until he eventually passed college at age eight. The Police tried to hunt him down, and nobody knows why. all of their cars blew up, and Iggy walked away telling anybody who would listen that he wasn't the guy they were looking for. He then punched them if they said anything.
