I was just bouncing around FA earlier today, mostly seeing what else people who Favorited me like (because I'm egotistical like that), when I stumbled across venom9999's gallery, and noticed in an earlier image post he had a version of rouge the bat with one of the spiderman symbiotes attached. I thought this was a neat concept and just did a quick doodle.

the lust symbiote concept belongs to venom9999
