Keep him away from sharp things, he might cut himself
He is quit and never makes eye contact. And since he isn't allowed near shapr things he mostly spend his time betwen the experiments with daydreaming. Alltough he don't talk much if another Creature talks to him he will start to talk. As long no guards are in the area
The scientists have made a lot of tests and experiments on his blood and heart. This have made his blood very lethal to others. Thats why he arent allowed near sharp things. The blood is filled with deadly toxics and other nasty stuffs. If a man swallows/gets his blood mixed with theirs they die shortly after. But it has also made it possible for him to heal himself. His heart pumps blood 20 times faster then a normal persons heart making it nearly impossible for him to die of bloodloss.
Like all the other Creatures.. Tests, tests and more tests
