So I decided to give Toxic Galaxy a character update.
He's a German club-going electronerd. My old character, Subwoofer belongs to him now. Toxic Galaxy created her as a companion and often takes her along to clubs and hooks her up for any sets he does as a DJ.
Toxic has a damaged voice box, as well. He created a collar to wear around his neck that speaks for him. It's got preset voices that he can switch between to sing for certain songs he plays.
