>The Corpse Clone Technique is a kinjutsu that allows the user to assume the identity of their victims. By opening their mouth wide, akin to a snake, the user will consume the target's living brain. After which, the user gains the victim's memories, abilities, and can take on their physical likeness perfectly.
