Octiron

The Octiron (五色がね) is an Axe Sword that can be wielded by Lexaeus in Kingdom Hearts 358/2 Days. It can be upgraded to the Octiron+.

Design
The Octiron has a peculiar, cross-like shape, with its blade split into two pieces. The middle blade is long, with a wide, flat tip and concave sides. The side blade fans out and sports two circular notches in its outer edge. The counterweight is of a similar shape and size to the side blade, though a bit smaller and lacking the notches. Both blades and the counterweight are black with indigo edges. The three blades are connected by a thick, white cross with red edges attached to the handle. The top tip of the handle is rust-colored and the pommel is decorated by a spike of the same color, while the rest of the handle is black.

Octiron is a fictional metal from the Discworld series, which is used to construct the most magical of artifacts.

Gameplay
The Octiron's normal ground combo starts with a two-handed downward slash, followed by Lexaeus leaping into the air while performing an upward slash, and ends with a powerful, two-handed downward slam. The -Combo can be activated after the first downward slash, and consists of a leap with an upward slash, followed by a powerful, one-handed downward slam before ending with a fast 360° spinning attack.

The aerial combo consists of a two-handed upward slash and a one-handed sideways swipe.
