Sorcerer
Sorcerers were enemies in Kingdom Hearts II who appeared in The World That Never Was. They are considered the strongest nobodies because of they're strong magical fields the can project and the fact they are resistant to magic.
Anatomy
Sorcerers have a strange anatomy, they move as if they were paper-thin. They wear what seems to be a full-body straitjacket, which keeps they're arms from moving, it has the Organization symbol on the front. Some parts of the jacket show the skin of the Nobody, which is black. Their faces have a cross on them, revealing they have no facial features.
Strategy
The magic Cubes that the sorcerers use can make it hard to get in close for an attack and to make matters worse they have no reaction command. The battle can be quickened by using Reflect at the right moment to deal large damage. A well timed reflect can destroy a Sorcerer in a single blow.
