|First Appearance||Washington B.C.|
The Mutant Hamster was a hamster mutated by Dr. Animo using his Transmodulator.
It looks like an ordinary hamster with brown fur, only much larger. It has eight red eyes and huge teeth.
The hamster can use its size to its advantage, and it also has enhanced strength.
In Washington B.C., the hamster was a regular hamster in a pet store until it was mutated by Dr. Animo. Animo controlled the hamster and had it fight Ben Tennyson and Dr. Kelly. It was eventually returned to normal.
