Contract Holders:
-Go Tamaki (formerly known as Julio)

Forms:
-Wolf: Go transforms into the Wolf Deadman using the Wolf Proto Vistamp. As a Gifftex, he can return to his human form at will. He has extraordinary agility and combat power using the genetic information of a wolf, and prefers a wild fighting style that is warlike and bares his emotions.

Arsenal:
-Rugir: Wolf Deadman's personal trumpet-like gun. The blade on its underside can be used for melee attacks.

Abilities:
-Fireballs: The Wolf Deadman can fire flaming shots from Rugir.

-Charged Shot: By clamping the jaws on his chest, energy flows through the red tubes and into Rugir before the Wolf Deadman fires a beam of dark red energy.

-Enhanced Speed: The Wolf Deadman is able to move faster than the enemy can react and catch them off-guard.

-Energy Punches: The Wolf Deadman can charge his fists with dark energy to enhance his punches.

-Smoke Dissappearance: The Wolf Deadman can disappear in a cloud of electrified red and black smoke.

-Riot: Go transforms into the Wolf Deadman Riot after witnessing Olteca transform Yosuke into a Gifftarian, effectively killing his best friend in the process. In this form, Go gains tremendous amounts of power, able to heavily injure even Olteca in a single hit. However, this state strips Go of self-control and logic, leaving him hellbent on destroying everything in sight, and attacking his opponents without restraint, similar to the fighting style of a wolf.

Abilities:
-Combustion: The Wolf Deadman Riot can generate and unleash burst of flames from his body powerful enough to destroy surrounding buildings.

-Supercharging: By clamping the jaws on his chest, energy flows through the red tubes allows the Wolf Deadman Riot to strengthen his energy attacks.

-Enhanced Pyrokinesis: Wolf Deadman Riot can now generate and launch red flames without the use of Rugir.

-Energy Claws: By charging his arm with reddish energy, the Wolf Deadman Riot can deliver powerful energy slashes that heavily injures his enemies with relative ease.

-Enhanced Strength: The Wolf Deadman Riot possesses enough raw strength to send a Gifftarian crashing into a wall with a single punch.

-Enhanced Speed: The Wolf Deadman Riot can deliver strikes faster than his original form.

Vistamps:
-Wolf Proto Vistamp
