Microwave

Microwave is an electrical appliance, and a minor antagonist who appears in The Brave Little Toaster Goes to Mars. He is voiced by Wayne Knight.

Role in the film
Microwave is first seen in the kitchen where he boasts to Ratso and the appliances about how useful he is because he helps heat formula for the Master's baby (aka the "Little Master"). He then proves it when the Master himself walks in and places a bottle of formula inside Microwave and warms it up for the Little Master. Ratso and the appliances dislike Microwave due to his boastful nature. He even offends the other appliances by calling them all worthless, and that the Master will never use them again.

Later, when the Litter Master is kidnapped, Toaster and the other appliances use him to travel into space on a rescue mission and take some cheddar cheese flavored popcorn, which they place inside of him, to help them fly. Microwave pops the unwrapped bag of popcorn, which is organic and provides them fuel to navigate through space. After the Little Master is found and rescued, the appliances prepare to travel home. When they run out of the cheddar cheese flavored popcorn, Tinselina (a Christmas angel that the appliances befriended earlier and who chose to go back with them) helps out by giving up her clothes and hair and placing them in Microwave so that they have something organic to get back to Earth.

Microwave is last seen playing tic-tack-toe on his touch pad with Ratso and beats him, much to Ratso's discouragement.
