About whether Powder, the character, is autistic - unknown. But parallels, yes!
Powder is an albino who is found to be a genius with (perhaps) certain special abilities in the sciences, notably electricity. He is very shy and outcast except by some of his teachers. He has been sent to public high-school after his reclusive guardians die and is housed in a group-home for young men where he is bullied. But it isn't a sad move, per se. Quasi-inspirational (?), I guess. Powder is a compelling character and there is the Aspie connection, for sure. Some good special effects.
