Has a dark sense of humor. Experiments on people for science (and his own amusement). He finds amusing a person that is cold, has a sharp tongue and is very hard nut to crack. Like Scaramouche, for example. finds joy in quarrels with him, and often teases him. Even that, enjoys talking to him. Likes to discuss various things and invites him to various kind of places. Likes receiving attention and giving it, but is very cautious towards strangers (instead of being genuine, he is rather mean)
