The Vortixx are my favorite BIONICLE G1 species, so I built one. I know that they don't have any canon red Vortixx, but there's a green one in the comics, so...
I've been building a lot of G2 stuff recently, so I decided to make some G1 stuff. After all, the largest amount of sets from 1 theme I have are G1 BIONICLEs.
"Scylla" was originally going to be male and be called "Sovereign."
I'm not sure, but I think the hands are from Bobthedoctor27's Bitil revamp, on CBW. If so, credit to him.
