Assassin

The Assassin is a high-ranking Nobody controlled by Axel that is found in Kingdom Hearts II.

Strategy
Assassins spend a lot of time in the ground. When they attack by flailing wildly, parry then attack.

If you can use the Reaction Command Fail-Safe, do so. This will make the Assassin explode, cause you no damage and still giving you Experience.

If you wish to fight powerful Assassins, the upper area of the Hall Of Empty Melodies in the Castle That Never Was is the only good place. However, in Kingdom Hearts II Final Mix, you can fight even more powerful Assassins in the Cavern of Remembrance.

Design
An Assassin has a vaguely humanoid body that is covered in a purple and silver bodysuit. Its segmented arms are each lined by four blades resembling spikes on the Nobody logo. Both the blades and segments they are on alternate from silver to purple. It occasionally uses its arms as "wings" to glide through the air. It appears to have a long tongue hanging from its mouth, which is mostly silver with a purple tip emblazoned with a small, white Nobody symbol. Assassins possess the same dumbfounding flexibility as all Nobodies, and occasionally compact their bodies into floating disks reminiscent of Axel’s chakrams.

The Assassin's name is based on the Final Fantasy job class of the same name.
