Rawk Hawk

Rawk Hawk, also known as the "Feral Nuclear Reactor", was the reigning champion in the Glitz Pit until Mario arrived to steal his title. Mario did this in order to obtain the Gold Star, which was supposedly found on the Champ's Belt. However, Grubba, the manager of the Glitz Pit, was in possession of the real Gold Star (the one on the belt was a fake) and was using the Crystal Star to power his strengthening machine, allowing him to transform into Macho Grubba. Rawk Hawk's only appearance was in Paper Mario: The Thousand-Year Door.

Rawk Hawk has a DVD as seen in Super Paper Mario. Francis owns this DVD of him.

Trivia

 * Rawk calls himself the Hawk. This (and Rawk Hawk overall) could be a parody of the wrestler The Rock.
 * In Super Paper Mario, one of the items listed on Francis' to-buy list is "Harder Than Bedrawk: The Rawk Hawk Story", which is apparently a DVD.
 * It is unknown if Rawk Hawk is really a stage name like Mario's is the "Great Gonzales" instead of his name.
 * Rawk Hawk will make a cameo appearance in Super Smash Bros. Brawl as one of the many stickers.
 * Judging from his attacks, Rawk Hawk seems to use the Lucha method of wrestling, involving acrobatic flashier moves. In terms of wrestling, he is also considered to be a Heel, a more villainous wrestler who would use dirtier underhanded methods regardless of popularity.  On a related note, a real wrestler known as Hawk existed in the 70s, who at first was a Heel but became so popular with fans that he eventually turned face for the rest of his career.
