He is an operative in his mid30s for the National Police Agencys Special Assault Team SAT. Though he is fully human he is as homicidal and apathetic to other people as the worst diclonius are. He is a hardy and effective soldier. After being maimed by Lucy and repaired with bionic cybernetic and prosthetic implants he escapes on a quest for revenge against her. He gets two or more Desert Eagle hand guns. In the manga he gets other weapons such as a RPG. The guns fire .50 caliber rounds which are so powerful the rounds can not be blocked with vectors. But the bullets can be pushed off course at long range though however at close range not even Lucy can stop them. Source: Wikipedia
