The fact that I haven't already said "Nope, sorry, drakes are just too far-out for my liking" is a point in your favor, because that would've been my initial knee-jerk reaction.
I do appreciate the effort you spent on it and am still considering Spooky as one of the 5 characters.
But I'm still having problems, RP-wise and mechanically.
Mechanically, I just don't know how Drakes work. I don't know how they 'balance'.
RP-wise, character specific, I'm sort of having problems with your answer to 15 (and part of 12). I'm not saying they're wrong answers, those don't exist on that kind of questionnaire. But it seems to me Spooky's a bit too much on the 'good' side of the law... At least, maybe for the game I have in mind. And sure, I could drag him into the story by his hair, but I'm not sure that's where you want this to go.
RP-wise, Drakes in general: First of all I'm not too confident in my knowledge of the SR-canon on Drakes. What I do know is that they're extremely rare, hunted down by dragon haters who want 'em dead and scientists who want to cut 'em open and that the few even-extremely-rarer Drakes that managed to survive and aren't indentured slaves to the Great Dragons are in hiding. I don't know how such a figure'd be out in the open or -even worse- in the shadows where everyone you meet would potentially sell him out for the right amount of cash.
It's the same problem I've got with ghoul (or other HMHVV) characters and several other kinds of builds. I just don't see why the rest of the team wouldn't just blow out his/her brains first chance they get. Sure, not everyone hates ghouls, but you only need to run into one shoot/sell-first-ask-questions-later kind of character for the game to be over.
Personal anecdote: When we were just getting started on Shadowrun and didn't really know much about the possibilities yet, one of the players showed up with a mage focused on possession. He was in a group with 3 or 4 other runners who didn't really know much about magic other than it was dangerous. It was the first time these 'runners worked together, things started getting dangerous quite quickly and everyone was on edge. So things start getting tense and the player of the mage character decides his character can use a boost. So the mage summons a spirit and lets it possess his mage character, granting him awesome stats and elemental powers. Meanwhile, around that mage character, there is a bunch of other people, his 'allies' he just met. Criminals who are all on edge, heavily armed and who all of the sudden notice the magic user they just met growing demon-like horns and becoming surrounded in flames. (I don't even think he could communicate.) So the rest of the players opened fire and killed the mage right there on the spot.
Looking back, I still think it's the only possible result that makes sense.
