Even though Metamorphia is a big female bobcat with purple body armor she was created by Grimer to assiant Dr.Robotnik to kill Sonic the hedgehog. She can transfrom into ANYTHING..talking Sonic himself, gas, a rocket, change her arms to axes or even fireproof forms she can even gain the ability from said preson/object however can't mimic it prefectly. She is a pure maniac able to trick her viticms easily and loves seeing them suffer. she also sees Robotnik as her hero.
