Bio Rex is a genetically engineered creature designed by the the group of scientists who would then form a racing team called Dinosaur Racing Team, which also designed the Big Fang.
This dinosaur is a product of biotechnology. Through this technology, his brain has become very similar to a human’s. If he wins the Grand Prix, he will prove that he’s superior to humans.
Utilizing advanced biotechnologies, Bio Rex was created from a fossilized dinosaur egg. Genetic design allowed for the development of higher brain functions equivalent to that of a human, but as a carnivorous predator, he still is as aggressive as Pico.
He first entered the Grand Prix to prove his superiority over humans, but this time around he has entered to satisfy his ravenous appetite for mammoth ribs.
F-Zero GP Legend
Bio Rex's Anime counterpart is one of the cronies that works for Dark Million, though he's more of a low-class lackey and works alongside Octoman, The Skull, Baba and Zoda. He is closest with Octoman, and is often seen as a minor character, except when he appears in the Women's Cup. Like the other cronies, they work for Zoda in Dark Million.
Super Smash Bros. Ultimate
Bio Rex appears in Super Smash Bros. Ultimate as a spirit. In his spirit battle, he possesses the body of a Wolf puppet. Ocassionally, various food items will drop down onto the stage. Consuming these food items will temporarily give the Wolf puppet a damage increase. Upon defeating the Wolf puppet, Bio Rex's spirit is earned. Bio Rex is a primary attack spirit that slightly increases the movement speed of the fighter they're equipped with.
- In Super Smash Bros. Ultimate, Bio Rex appears as a spirit and his spirit fight is represented by Wolf from the Star Fox series.
