Ape-X is a shy fellow. His father was an engineer and his mother a physicist, so he's basically 50 percent formulas, 50 percent proofs, and 50 percent imagination. He got the brains, but the most extroverted he gets is when he's looking at your shoes instead of his during a conversation. His favorite proof is proof by intimidation. It's trivial anyway. Yes, he might have spent some years in a special facility to help with his mental disorder. He was taken there by his brother e^x after he stormed a bus and threatened to integrate and differentiate everyone. Of course, Ape-X birth number is a prime, something he's very proud of. His biggest weakness? A slice of Pi. You might want to avoid him at lunchtime, but you know that he's actually a decent companion, especially if he's in your study group or wallet.
