XLR8 resembles a semi-armored Velociraptor. He has black wheels on his feet and wears a helmet with a visor, leaving the other features of his head unknown. Whenever the visor does come up, one can see that he has a blue face, green eyes, black lips, and stripes above and on the right side of his eyes. He wears the Omnitrix symbol on his chest. He also has five blue stripes on his tail.
