"Probably going to have to work on equipment (ISF has their own ships and our characters will be assigned undercover vessels for this mission), abilities could be detailed similarly to other sheets though I don’t mind the innate tech abilities or the telekinesis as it seems fairly balanced, but there are some awkward bits with the backstory such as him hacking WTO servers? If it was that easy I imagine the ISF would have a lot more information on the WTO. Though his vigilantism is an interesting angle, I find it obtuse that the ISF would just recruit as implied. Could use some work around the edges."

Actually, he hacked their clients, not them.  Example.  Space Microsoft is building Xbox Ones on Freeza Planet 617, AKA Sonata, using slave labor.  The police can't look too deeply into it because Space Bill Gates made some generous campaign donations, but I don't care.  I find evidence of not only that, but that he spent 1 million Spacedollars on an Arlien prostitute, and the news agency learns about it.

I could turn it into a kind of "build insect camera and have it follow them." thing, like Dr. Gero, though.

If he turned over his info/tech to them, would that be enough to earn their trust?
