Given how much fanfic I've written over the years, it'd be jerk of me to be all 'no fic'. And I think it's super cool that someone is inspired by something I've done. But you can't make more money off it than I do ( so stay below zero.
)
Beyond that, the one thing I will hold firm forever on is Aquaan skin colours. They're brown. I don't care if they're great bioengineers and could change their skin colour if they wanted to. They don't want to.
( They could bioengineer up a beard, though, if one decided that facial hair was cool. )
