Hehe, my opinion on keeping Bonnie (old, toy, or any) as androgynous and no specific gender still stands! Not gender less necessarily, mind you, but still no specifics!
(Yes, I am aware they are technically male as confirmed by the second game. But regardless, I still like that bit of freedom with Bon’!)
Plus, whenever I drew Bonnie and people still had that bit of ‘debate’/'argument’ over this, I wanted to satisfy all parties. If they seem female to you, great! If you just stuck with male, just as great! Neither, 'cause robots, sweet! Anything inside/outside the spectrum, fantastic!
