Full Name Kingfin
Species Fishbone (uncomfirmed)
Class Boss
Koopa Troop
Vulnerable To Koopa Shell
First Appearance Super Mario Galaxy

Kingfin is a boss that appears in the Mario series. It seems to be some kind of skeletal shark. Although it is one of the largest characters, it is somewhat lacking in defense. In Super Mario Galaxy, the player fights it underwater in the Bonefin Galaxy, and has to throw shells at it to defeat it. There is abeam of light that comes through its eyeholes, sort of like flashlights. If Kingfin sees Mario during battle, it will simply chase him. Sometimes, you can use this as an advantage to hit Kingfin with a Koopa Shell.

General Information


Kingfin is a colossal skeletal shark in appearance, although appears vaguely crystalline. This is interesting as sharks are cartilaginous, which means they do not have a skeleton like Kingfin's. Kingfin has beams of light appearing out of his eyes, but only when battling Mario. Due to perhaps what might be glitch in Super Mario Galaxy, his lights do not shine when Luigi battles him.

Powers and Abilities

Kingfin is able to summon Fish Bones that hone onto foes, and is able to swim in water at a decently fast speed. He is only able to sustain five hits with Koopa Shells.


Kingfin mainly appears in the Mario series as a boss.

Super Mario and the 8 Elemental Crystals

Kingfin reappears as the boss of Fishbone Swarm Tower, in World 4: Shoreline Beach.

Paper Mario 5: The Rise of Shadow

Kingfin reappears as the boss of Chapter 11. It is the beast responsible for attacking Great Ocean City and kidnapping Princess Syrena.


"That's Kingfin. A monstrous skeletal shark-beast that lurks these oceans. Max HP is 75, Attack is 4, and Defense is 1. It can summon smaller Bonefins as minions. Bonefins have a Max HP of 12 and an Attack of 1, but there are almost always like 3 at a time. Say, come to think of it, sharks don't have skeletons. So why does Kingfin?"

Super Mario Throwback

Kingfin gets a new look for Super Mario Throwback, a 2D platformer. He resembles a Fishbone in this game, but he wears a crown, is gray, giant, and has orange eyes.
