Tank (Experiment 586)

Tank (voiced by Frank Welker) is Experiment 586 of Dr. Jumba's Experimnet. He is designed to eat metal and grow exponentially larger with any type of metal he consumes. He was captured by Gantu, but was rescued in "Snafu".

His one true place is eating scrap metal at a junkyard.

Appearance
Tank is a round orange, armadillo/bulldog-like experiment with thick legs, black eyes, an oval nose, a large, wide mouth, sharp teeth, a short tail, short ears and plates going from the front of his head to the end of his tail.

Primary Function
Tank has exponential jaw strength, enabling him to chew metal with ease, such as iron, steel, tin, copper, aluminum, etc., and he was able hold up an automobile with the bumper in his mouth. His overbite jaw is also able to stretch amazingly, allowing him to eat things many times his size (such as a factory). His body size increases exponentially with any metal he consumes. Tank's digestive system must work hundreds of times faster than a regular human being's, as he ate a car bumper many times his length without struggle

Trivia

 * It's possible that during a period from when he last ate some metal, he'll shrink back down to his normal size.
