Dave is 26, a Dutchman.
He's serious, but yet caring. A bit silly, too.
Works as Algebra Teacher & is a past scientist.
He's used some habit of stuttering when surprised.
Wears a black visor & red suit with text saying "robot suit" on the torso.
Tends do act insane & always gets some crazy ideas that no one is capable to think of.
The insane smile of his never leaves his face, but that never means that he has bad intentions. The smile is more friendly, than dangerous. That's just the way he is.
