Mileena is a lazy, slender Delphox who is very talented with magic. She's especially gifted when it comes to transformation spells, which she found a very good use for. Mileena regularly transforms other Pokemon into pieces of clothing, her magic making it so they are extra comfy and durable, perfect for large pokegals who tend to rip their underwear.

Mileena is very laidback and loves to just do nothing and sweat on her couch more than anything. She can also be extremely cruel and sadistic, using her spells to make clothes for herself and others. A Gardevoir called Emma has been her favorite victim, as she's the comfiest pair of flip flops Mileena ever had.
