The Transmodulator is a device that Dr. Animo uses to control and mutate different animals. He first uses it in Washington B.C.
It is a blackish helmet with long horns sticking out. At the top of the horns is a red bulb. The helmet also has what looks like headphones. Dr. Animo controlls it with a battery pack on his wasit.
It can mutate different creatures and also bring dead creatures to life.
