Kingfin is a boss in Super Mario Galaxy. In the Prima Games guide, an issue of Nintendo Power, and in his Super Mario Galaxy trading card, he is called "the Bonefin", possibly because the name of its galaxy is Bonefin Galaxy. His name is most likely a pun on the word "kingpin", which refers to the most important person in an undertaking or organization, such as a galaxy boss. Kingfin commands a legion of Skeletal Fish Guards and is himself a colossal skeletal shark, although in actuality, sharks are cartilaginous and do not have bones. Kingfin also has beams of light shining out of his eyes when battling Mario. However, if the player uses Luigi, his eyes do not shine. Through a simple glitch, the eyes won't shine if the player uses Mario, when the player bothers Luigi in the Observatory (spinning at his proximity/jumping on him for example) before entering the Bonefin Galaxy.
When Mario enters the waters of Kingfin's planet, Kingfin will appear with some Skeletal Fish Guards that track Mario down to attack him. There are only two ways for Mario or Luigi to defeat these guards; they must lure them to the surface or into a wall, or throw a shell at them, which causes them to drop three Star Bits upon impact. If the fish touch the surface they will automatically explode. The only way to defeat Kingfin is to grab a Green Shell or a Red Shell from the seafloor of the planet and spin to launch it at Kingfin. After one hit, two guards will attack Mario. After two more hits, four guards appear to attack him. Once Kingfin has been hit a total of five times with shells, he will explode and release a Power Star. The battle can be made easier with the help of a Life Mushroom hidden in a pillar, as well as a submerged treasure chest, which contains the only 1-Up Mushroom in the level. The pillars are destroyed by Kingfin ploughing through them; he destroys two shortly after getting hit once, and he destroys two more after taking another two hits.
Kingfin appears in volume 40 of Super Mario-Kun.
