Assassin
The Assassin is a Nobody from Kingdom Hearts II. It is first found in the 6th day of Twilight Town. Assassins usually move slowly and within the ground, much like Shadows do. They will jump out of the ground or flail their arms to attack. The reaction command, Fail-Safe, allows Sora to grab one of the Assassin's arms and plunge the Assassin into the ground before it explodes. It seems Axel mostly controls these Nobodies as well as Dusks. The self-destruct attack used by Assassins could be a reference to Axel's death, as Axel also sacrificed himself in battle. Its name may also be a reference to Kingdom Hearts: Chain of Memories where Axel assassinated Vexen and attempted to assassinate Marluxia. It may also be a reference to the Dark Knight Job in Final Fantasy, which used self-destruct attacks as well. After Axel's death, Assassins become an incredibly rare enemy, the only area where they are found being the room before Proof of Existence in the castle that never was. They are found in Olympus Coliseum cups, but they don't drop anything.
