Kingdom Hearts Wiki

The Arch Behemoth can be found exclusively as a boss in Kingdom Hearts Final Mix.


The Arc Behemoth has a massive body, with a huge barrel-like chest that tapers into its back end. The Heartless Emblem is located on the underside of its chest. Its coloration is a dark grey-blue on the underside of its body, with a light blue on top in the design of flames. These flames extend to its shoulders of its large front legs, which are much larger than its back legs. A very light blue decorates its forearms, and the feet are black with more flames extending onto the forearms.

Its four feet all have a circular pad on the bottom, with two inwardly facing claws on the front. Its back legs are shorter, but boast the same color pattern as the front legs, with the black of the feet extending all the way up to the knee. The Arc Behemoth's mouth is jagged and extends outwards into two large inwardly curving tusks, which are colored black. The forehead is flat and the eyes sit facing forward, and glow yellow like the other Heartless. A conical, grey horn sits at the top of the head, facing forward at a slight angle.


At the start of the battle, Arc Behemoths will most likely begin by loading up the orb that he launches in the sky. If you want to avoid getting hit by the orbs that fall down, try to sneak under it after it has launched the orbs into the sky. After that, you'll want to focus on getting on its back and repeatedly attacking its horn.

If it is stunned, do about two combos and then back away, for it will cast Thunder, which will hurt a lot. If you get away from it, this will miss. Keep doing this and eventually you'll beat it. Cast Aero if you can't avoid getting hit.

Stats & Abilities

  • Energy Rain: The Arc Behemoth charges energy from its horn and, after a few seconds, causes energy balls to rain from the sky.
  • Thundaga: After the Arc Behemoth is attacked and regains consciousness, it retaliates with a widespread, nearly unavoidable Thunder attack.
  • Leap: The Arc Behemoth occasionally leaps from one place to another, damaging Sora if he is too close.

The Arc Behemoth's name and design is based on its appearance in the Final Fantasy series; Behemoths are large, horned creatures with massive strength. When "Arch" is used as a prefix, it usually means that the subject is highly placed in a hierarchy. This contradicts the Heartless's weaker strength when compared to the original Behemoth.
