Riptor is a crossbreed of human and reptilian DNA, made by Ultratech and one of the playable characters featured in the original Killer Instinct.
Riptor is a human/raptor hybrid, having the basic appearance of a velociraptor but with much larger arms, a humanoid muscle mass in the chest area, and broken shackles hanging from its wrists. The color of its scales changes depending on its renders and in-game appearance, ranging from primarily orange with black stripes not unlike a tiger, to green scales around its back and tail to orange scales on the underside of its body.
A product of UltraTech's DNA manipulation project. By splicing human and reptilian genes, they have created a fighting creature with animal ferocity and human intelligence.
Another of Ultratech's miraculously realized concepts: a crossbreed of human and reptilian DNA, resulting in a creature that combines formidable intelligence with sheer brute strength. Nurtured from the egg by a dedicated Ultratech professor and her team, the beast nicknamed 'Riptor' by others has barely reached 4 years of age before it first demonstrates its full savage power in a human kill. Riptor is confused and often finds itself torn between human reasoning and predatory instincts, resorting to attack when it fails to understand the situation, as ever more people find out the hard way.

Riptor did not appear in Killer Instinct 2. In TJ Combo's character profile, he was said to have had a "decisive victory over Riptor", implying he had put an end to Riptor once and for all in the previous tournament.

- Riptor has a hidden cobra hood which it only unfurls when it prepares one of its three No Mercy-moves.
