Diamond

"I'm just another stupid good-for-nothing, yeah."

One of the less savory humans to have transformed into a Pokemon, Diamond came from a rather well-off background, although they ended up falling into the wrong crowds at some point and became a sort of jerk to everyone she knew. After getting herself into some bad crowds and doing some less-than-legal petty crimes, she wound up swindling people out of their money in simple card games.

After becoming a Pokemon, she quickly got herself into trouble defacing a few buildings and shoplifting from the bakery (for fun). She's been in and out of the Pokemon prison a few times, but as of the last time, the big Magnezone in charge decided they try something other than just letting her go.
