Harris is Tonto's pet ,Xander's rival and partner in southern cheese rusling. He once was a gator egg that Tonto found while fleeing from angry red necks in a bayou, and decided to take it with him. Inspired by Zak Saturday's pet, Komodo, Tonto genetically modified him to be able to leviate like a hoverboard, increased intelligence and the ablitity to breath fire. Unlike his owners, he doesn't originate from Omnination, but from the Blues Country, home of the Blues brothers.
Omnitrix at one point gained an Omniharris form. Like his owner, he deeply hates the Hunters of Artemis
