Go Jetters
Grandmaster Glitch (Marc Silk), a troublemaker who is a disgruntled former cadet of the Go Jetter Academy. Glitch likes mud and having fun, which usually involves destroying or using a landmark to achieve his plans. He has a large moustache, used as his trademark, and funnel-like pieces on his helmet. He calls the Go Jetters several names and accuses them of screwing up his fun, and his catchphrase is "Grimbles!" which he says in frustration. He travels around in the Grim HQ, a rusty rocket ship that leaves a trail of smoke, and has a teddy bear called Cuddles.
