He seems all over the board -- all I can tell is he's probably some sort of intuitive. A little about him:
-He loves speculation. He's a big sci-fi geek, likes a few anime shows, and loves discussing weird ideas and crazy theories about how they're all interconnected. He also frequently goes off on random tangents, despite being perfectly capable of speaking in an organized manner (and doing so most of the time).
-He's an obsessive planner, arrogant as fuck and ridiculously competitive (can't bear losing -- I generally get tired and give up on debates with him because he'll just go on and on till I concede). He's not happy about any given situation unless he has a plan to deal with it and then a minimum of two backup plans in case the primary fails. He essentially treats life like a chess game. Despite this, he's very lazy and messy, and he's good at solving things on the fly -- often coming up with ideas for meticulous plans in split seconds out of the blue. He gets a massive kick out of doing that, usually going all "AHA, I WON!" about it.
-He's an ace at manipulating emotions, and has a Hannibal Lecter-esque ability to read other people like a book and mindrape them to oblivion. He loves fucking with people for shits and giggles, sometimes even in life-destroying ways. He himself is also very personally emotional, but he never shows it outwardly, only confiding his real feelings to his closest friends; although sometimes he bursts and can become a raging psychotic animal.
-He has the memory of an elephant, but he's very bad at rote memorization. He stores essentially his entire life unintentionally, but he can't bring himself to remember what he reads in a textbook. Similarly, he's very bad at number-crunching, but exceedingly good at abstract math.
-He's sharply attentive to details when he wants to be and has a very forceful presence, but he often ignores the outside world, preferring instead to focus on his own plans, schemes, analysis and crazy ideas. He adores theoretical discussions, and loves telling people what to do, but dislikes menial small talk and most other social interaction. Despite that, he has rather strong social skills.
-He's very witty and funny, cracks snide, sarcastic, or frankly odd jokes every five seconds, despite being entirely serious otherwise.
-He has a tendency to be very businesslike around new faces, but to act weird and random around people he actually knows well. His family is moderately wealthy, and he's very fixated on his own wealth and status.
-Self-centered, self-absorbed, vain, appears to think he's the most brilliant and attractive guy in the world. Not too unlike myself.
-Despite being a bastard he loves his girl dearly, deeply. He's very clingy, neurotic and obsessive about her, unable to let her go no matter how badly she treats him. he's also unable to shut up about her for more than ten minutes, if that.
