Riptor is a crossbreed of human and reptilian DNA, made by Ultratech.
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.
Ultratech's plans at creating a genetically engineered weapon have escalated beyond even their control. By toying with the laws of nature, UltraTech have finally doomed the human race.... Dinosaurs once again rule the Earth.
Killer Instinct 2
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.
