a) A human male who uses some form of telekinesis for just about everything he can do.
b) Average height, thin, blonde hair with blue eyes. Didn't/doesn't wear a costume. By changing his clothes for each job, he figures he won't stand out as much. He does have a signature knee-length black coat that he likes to wear sometimes, however.
c)His TK separates him from everyone - he was born with it, so he's known since he was a small child that he was different from everyone else. He can do almost anything with it, from flying to lifting things (including other people), throwing things, deflecting things coming at him, etc. [Details TBD by his build.]
d)Before the V'Sori, he was a successful sneak thief. He would use his TK to enter a place, open the vault / safe / whatever, and get the goods. He could crush any security cameras, so no one ever got a good look at him. He vividly remembers that his last job before the V'Sori wiped out the heroes was a high-end jewelry store.
e)In the last two years, he's really stepped up his game. He's been using his powers to nip at the heels of the V'Sori, decimating their patrols, attacking lesser-guarded facilities and wrecking them, destroying their smaller flying machines (while they're on the ground), doing whatever he can to weaken their coordinated efforts to control mankind. He was captured at a facility that was more heavily-guarded than he expected (in retrospect, he thinks that might have been due to he previous attacks, so in a sense he was his own reason he was captured).
f)The most interesting person he's ever met is Flying Fortress. He met her by accident, they both happened to attack the same V'Sori station at the same time. She wears complete-coverage armor that enhances her strength and allows her to fly, so together they made quick work of the place. Their banter during the attack led to their meeting up IRL, which eventually led to their hooking up to do jobs and...other things. She was just recently killed by the V'Sori while attacking a large research installation, and he still mourns her loss, and now his anger at the V'Sori is personal.
g)The greatest thing in his life *was* Flying Fortress. His current goal, the most important thing in his life, is to wipe every single V'Sori off the face of the earth.
