Ice Release: Frozen Fangs Technique

By freezing the blood in the user's mouth, they can coat their teeth in Red Ice allowing them to bite an opponent with much more force than normal and absorb their chakra at the same time due to the properties of Red Ice. This technique is considered one of last resort due to the proximity the user must get to the targer.

Trivia

 * This is the technique that made Sanger infamous during his first Chunin Exam when he bit of a part of his final opponent's arm.
