Heiress to the Mushroom Kingdom nearly doubled personal net worth after terms of divorce from hero plumber Mario awarded her a fortune in gold coins. Said to enjoy tennis and go-kart racing, owns over 600 outfits in the same pink color. But life has not always been easy for Peach, who has been kidnapped repeatedly since childhood by Bowser, king of the turtle-like Koopa race. Trauma evident, say friends; Peach fantasizes that she has ability to float in the air for several seconds; mutters about "Goombas," "Cheep Cheeps," "Bob-ombs." New member.

Let the fandom debates begin, especially with her divorce from Mario. Heh. Special thanks to Wikipedia.org.
