The Supreme Commander is the main antagonist of "The Brave Little Toaster Goes to Mars". He is a giant refrigerator who is bigger than all appliances and rules Mars. In reality, he appears to be a hearing aid (the long-lost brother of Hearing Aid) in a smaller refrigerator in an icebox in (of course) the giant refrigerator. He hates humans because of a bunch of appliances being built to fall apart. He is voiced by Alan King, but voice actor Jim Cummings did his singing voice.
