Finally done with these two. For anyone who's curious, they are based off of two dogs from alien horror movies that has a parasite they ingested and they die birthing the alien creatures (although one was more of a carrier than a literal killing machine). Here are some concepts of their designs that also explains the dogs in the movie:

Now I did say I would make a huge bio about them including the parasites in their bodies, powers, abilities, weapons, etc. However, upon finishing them...I have yet to explain them entirely to myself. Hell, other than their names I really don't know anything about them. What started as them being based off of their movie counterparts and them being into Mpreg, I moved to making them more original that I have no clue as to what to do with them. IDK, sometimes I overthink my artwork and characters too much. I'll try to figure it out later on, but at least for now its here for all your viewing pleasure. With that said, enjoy. ^^
