Dewback (Earth-2042)

"And look, those animals, I can't explain it. There's something graceful about them. They just move like every particle of 'em is perfectly aligned and entirely free. They'll take you through a storm, over a river, into a building. They'll maul the kriff out of anyone that gets in your way. They're basically a stormtrooper's best friend."

- Unidentified sandtrooper

Dewbacks are thick-skinned reptiles native to the desert planet of Tatooine, where they are used as beasts of burden, as well as mounts for specialized sandtroopers known as Dewback troopers.
