Maximix is Mong's robot. Maximix has a unicycle propulsion instead of legs and is also capable of transforming into a Go-kart like vehicle to provide Mong with transportation. Although not as strong as Cubix or Kolossal, Maximix has proven himself to be a formidable opponent on several occasions. He can hold his own against Kolossal or any of Dr. K's robots. Thanks to his unicycle propulsion he can reach high speeds and is quite agile. His personality is similar to his master: hot headed, competitive and a little conceited, but always reliable. Maximix's voice is similar to that of Arnold Schwarzenegger.
