Mad Wolf (BBC)
Billy is an F-Zero racer pilot first introduced in F-Zero X. He returns playable in F-Zero AX and in F-Zero GX.
Overview[]
Billy is the first monkey to enter F-Zero. One of his ancestors was a trained rocket pilot and the first monkey in space. Whether by genetic predisposition or not, Billy's ability as a pilot is truly exceptional, and he's the first monkey to enter the F-ZERO Grand Prix. He was raised in a special lab where he was educated in human literacy and communication skills. The lab concurrently developed an F-ZERO racer suitable for a monkey, and bestowed upon him the honor of piloting it in the Grand Prix.
His species seems to not be specially intelligent, since he himself was trained in a laboratory in linguistic skills and eventually to enter the F-Zero races. He's since competed for two years, though he has yet to win the Grand Prix.
When he is interviewed in F-Zero GX, Billy usually talks about money, such as how he became a racer "for the money."

He doesn't really play a significant role, other than being a miscellaneous pilot in the tournaments, such as the GX race and the GPL races; he was only able to advance to the Cosmo Terminal quarterfinals.
It was said in Worriment of the Future that Billy passed by the age of ten by natural causes; as a side effect of his experiments. He did have some fans who were the Genomes, monkey-like humanoids, who reside in Port Town's distant treehouses across the space harbor.
Trivia[]
- In F-Zero GX, the character AiAi, from Super Monkey Ball appears on Billy's belt.
- He bears a slight resemblance to Andross and Andrew Oikonny from the Star Fox franchise seeing as they are monkeys. The only difference is their fur is white/grey.
