Giga Goojin was Gimme's Flagship, having transformed, created by The Geathjerk. It is widely believed this fight and one before it are an homage to the "Punch-Out!!" series started on the NES with "Mike Tyson's Punch-Out!!" as the gameplay and controls of the fight share striking resemblance. Piloted by High Geathjerk Commander Gimme, Giga Goojin will attack you with a wide array of melee moves and later in the fight, will resort to more untraditional means of battle, by summoning 3 different types of robots(Ohdarko, Kazoir Diejeah, and Kazior Orowchee) with their own unique ability and by throwing Gah Goojins and Wallgah-Goojins.
In this fight, you take on the role of "Platinum Robo", piloted by the Wonderful 100. Platinum Robo attacks in a very similar fasion to the protagonist of the "Punch-Out!!" series, Little Mac, as you are able to sway from side to side and guard from Goojin's attacks and attack him by delivering left and right gut blows/uppercuts and delivering a knock out punch counted by Platinum Stars, only being able to carry 3, similar to Little Mac's signature Star Punch technique, where he to can only carry 3 stars.
