Chareau de Red, Christopher

A homunculus created by Huey Laforet in the late 1800s, and a member of the organization Lamia. He has constantly bloodshot eyes and razor-sharp teeth. Due to being rather unnatural himself, Christopher is obsessed with nature and often frantically talks about how amazing it is. He also has a tendency to break into song when fighting, much to his fellow homunculus Chi's displeasure. He takes orders lightly and is considered something of a wild card in the organization due to his chaotic personality. In combat, he uses gun-knives. The younger homunculus Rail looks up to him. Christopher values friendship highly.

[Spoiler] After losing a battle with Vino in 1933, he is rescued by Ricardo Russo, and becomes his bodyguard.

It's implied that Nile broke his original teeth. He also forms a rivalry with Graham Specter, although they team up at one point to protect Ricardo. [/Spoiler]
