Bio Rex

The creature Bio Rex was designed by the Keerlon Corporation. His creation is the result of genetic manipulation research that was outlawed on Earth centuries ago. He was created from the DNA of a fossilized dinosaur egg, but altered to have human-level intelligence and increased strength. Genetic design allowed for the development of higher brain functions equivalent to that of a human.

However, before he even got to race, he had to endure several press conferences, interviews, public appearances, and was constantly under constant public scrutiny. Eventually, his patience reached a breaking point and his fiery temper caused some rather embarrassing bad press for the Keerlon Corporation. They distanced themselves from Bio Rex, who still intended to enter the Grand Prix. During his first year he, as a 'new species,' was determined to prove he was superior to humans. However, the following year he entered mainly to satisfy his ravenous appetite for mammoth ribs. Although Tinsel said once as mockery that he shouldn't since they're very fattening.

Ikran's F-Zero timeline
Bio Rex was portrayed as one of Zoda's henchmen, mostly as a close mook to Octoman. He didn't have much to represent except during Ending it All. During Tinsel's first race at Green Plant, she dealt with him and Octoman, though the latter was easily defeated, the former hit like a truck. He was overwhelmingly difficult, fortunately she was spared by a mysterious pilot named Beastman, who was preoccupied hunting for the engineered carnivore. He did give him the slip, though. He was later seen again as he was being pursued by Chris, Tinsel, and later Jack and Gomar & Shioh. His Big Fang was wrecked, even when it crashed into a truck full of manure in the Mute City highway. He was then taken into prison by Chris, fulfilling his vengeance, at last. His parts of the Big Fang was scrapped away then being used to enhance the Task Force's vehicles, such as the Silver Comet, Astro Robin, Twin Norrita, and the Dragon Bird.
