Sid Barrett

A man who died and turned into a zombie. The rumors of the school said he got the idea of absolute freedom stuck in his head and started attacking students to show them the amount of freedom dying has brought him. When they found Sid in the graveyard, he fought them by using his own gravestone as a substitute weapon to great effect. It was shown that Dr. Stein turned him into a zombie and thus was targeted by the Maka and Black Star's teams as part of their remedial lessons. It was later revealed to be a trick set up by Shinigami and Dr. Stein to show the students how to see and use soul energy (only Maka could see it after the assignment). Since then, Sid acts as a spy to get information on the witches and their plans. He constantly talks about how he has always been "that kind of man" (when he was alive) and the things he could not do when he was alive but now can since he's a zombie. During his time when he was alive, Sid was a three star meister and a knife meister. His job was taken over by Dr. Stein. He still goes to the school to help the student and teachers in any way he can. Sid's reason for helping the school is that it is what he would have done when he was alive. He is named after Pink Floyd's original frontman Syd Barrett.

Attacks: Sid uses his own gravestone as a weapon or Nygus in her knife form. He is also capable of using Azusa to make sniper attacks.

Living End: Sid's signature attack where he uses his gravestone to pound his opponent into the ground, creating an enormous cross of soul energy. It can be utilized on the ground as well as in the air.

Compulsive Burial: Sid activates Soul Resonance with Nygus, then stabs her (in knife form) into the ground which causes coffins to appear below a person and act as an escape route. This technique creates a simple way of escape by the means of an escape tunnel going directly downwards.
