His first diaper and the one he wears all the time is a zorua named Zen, a well known trickster and thief who loves making trouble and playing tricks on exploration teams, mercenaries, and even criminals. Zazzy taught him a lesson by turning him into a thick poofy diaper to wear around his waist and bring along in his adventures. Zen can still use his illusion power even as a living diaper, which helps Zazzy on jobs by changing him to look like another pokemon and even blend into the background.
