Baaba

 He's quiet, but doesn't hesitate to speak his mind when he feels like it. It's basically impossible to get him embarrassed because he doesn't care about what people think. He doesn't like to talk much and if he's not in the mood he'll just plain ignore the person who's approaching him. He's stubborn as a mule and won't do anything he doesn't want to do.

 He's an existential nihilist? He feels nothing matters so he doesn't worry about what people think of him, so he's somewhat selfish. He's depressed and unmotivated, wanders aim and almost endlessly, collecting things that catch his eye. He has somewhat of a hoarding problem. He specially likes crystals and other shiny things, but he's intrigued instinctively by machines.

 He doesn't like living; everyday is the same and meaningless. It's unknown to him if he's capable of dying, but he hopes he is. Because he doesn't need to eat and such, sometimes he'll just lay down and "sleep" for days on end. He can't truly sleep though; his power never runs out. He loves to watch the sun rise and set though; all the colours and details, it's so beautiful.

 He actually likes physical affection very much though it's hard to tell. He doesn't make any effort to hide it, he's just very selective of who he wants the affection from; plus people usually think he's unapproachable(and are right often) so it gets hard for him to make friends. Despite so, he's not as bad as he seems, he's just intolerant; he'd probably be shamelessly clingy with friends.
