Guren (prisoner)

was a prisoner at Orochimaru's Northern Hideout. He received a cursed seal in the course of Orochimaru's experiments.

Appearance
Guren has long shaggy orange hair. When activated, the cursed seal he possesses resembles vines as it spreads across his body. In its level two state he grew wing-like protrusions from his forearms and a broad flat tail. While in his second state he had two horns one sprouting from each side of his forehead and two more one coming from each side of his cheeks. He also wore a white T-shirt and a white pair of shorts. In his second state, his eyes turned black with the center being a yellowish color.

Abilities
He was able to enter the second state of the cursed seal, but was powerful enough to brutally massacre all the prison guards with just the first state. He was also powerful enough to kill a man with just a single blow to the head. He could also jump down from really tall places and he used appendages that grew on his arms while in second state to cushion his fall.

After the prisoners had heard rumours of Orochimaru's death and began to revolt, Guren escaped and after entering the first stage of his cursed seal, brutally killed a number of guards who tried to subdue him. He later escaped to the outside and attacked Sasuke and his group, he was however quickly defeated by Sasuke Uchiha.
