Dichotomy

Dichotomy (クロケアモルス) is one of Saïx's weapons in Kingdom Hearts 358/2 Days, and Dichotomy+ is his most powerful weapon. To wield Dichotomy, Saïx must have the Pandora Gear attached. When used Saïx Attacks with this weapon, he executes a four hit combo in which he performs a fast downward slash followed by a similar upward slash. Saïx then jumps, slashing his claynore upwards, and dashes forward whilst in midair, and spins with the claymore extended, dealing a devastating blow to whichever unfortunate half-wit heartless happens to be in front of him.

Dichotomy is the phase of the moon where half of it appears visible, possibly a reference to how Saïx is both calm and berserk. "Crocea Mors" is Latin for "yellow death" and is the name of Julius Caesar's sword, according to the writings of Geoffrey of Monmouth.
