XLR8 (pronounced "accelerate") is the Omnitrix's DNA sample of a Kineceleran from the planet Kinet, first appearing as one of Ben's original 10 aliens and regularly appearing in the franchise since..
XLR8 resembles a semi-armored Velociraptor. He has black orbs on his feet, a black tail with five blue stripes, and bulky claws on his three fingers that can only open and close. He wears a black cone-like helmet with a protective visor that slides over his face (that is part of his Kineceleran biology and not mechanical). When the visor is lifted, one can see his blue face, green eyes, black lips, and stripes running under and in between his eyes; the rest of his head's features are unknown. XLR8 wears a black bodysuit and turtleneck-like shirt with a white stripe on the center.
In Ben 10: Omniverse, XLR8 is now taller and the white color on his shirt is replaced with green, which now covers his neck. The number of tail stripes have gone down to four, the black balls on his feet are bigger, and his visor is darker.
