Rule63: Hellboy

Hellgirl (Rule63: Hellboy) by Alexandra

I think this is one of the best genderbent character cosplays I've seen.  At least, the costume makes me wish that this was an actual comic.  I think Hellboy would be a more interesting character with a sort of River Song-like personality.

Not all Rule 63 cosplay has to sexy.  Sometime it's refreshing to come across a bit of Rule 63 that's even more terrifying than the original.

"Its been a while since I've posted but Im super happy about this newer cosplay I made. I made all of the cosplay myself as well as makeup/styling. The God Of War series is definitely one of my favorite franchises and definitely had to do the Golden Fleece version. It was my favorite and also the hardest to make. This cosplay took me one week without much sleep just to be made in time for PAX East."
