Diamond

Diamond is a fictional character that appears in the first Golden Ninja book, Glass Arm. He is an operative of SCORPION and is sent by SCORPION’S chief executioner, Bat, to give another member of SCORPION a suitcase full of money, to fund other SCORPION operations. He succeeds but is killed by PSIA agent, Golden Ninja. Ninja kills him by firing a bullet in his Diamond embedded eye, killing him.

Diamond is described as a skinny man, who has a Diamond in bedded in his right eye, which is why he was nicknamed Diamond.

In Glass Arm, when Diamond leaves Golden Ninja for dead, he shouts Au Revoir, which is French for bye, which implies that Diamond is French, or he could have just said that because he was heading for Paris.
