It's an odd idea I had a long time ago. I just finished it & it's almost 1Am here. :dead:
Did the sketch. Used a layer in photoshop to half ass the lines I did, using the brush tool. & colored as well.

The idea for the type of nage he is, for his legs, phasing into the naga part about halfwaty from the thighs came from a few pictures of a Naga chick I saw from one of those Chan boards with Ragnarok online stuff or something.

Those pants he's wearing are specially designed for the type of mage he is, due to him having a gap still where his groin & thigh area that isn't fused. Basically, the pants wrap themselves around his waist. A type of flap from the back goes over the crotch & a couple other flaps wrap around his thigh areas. It's those botton things you pop snap on & off, with a small amount of force.

My brain is tired & finally felt like drawing something. Alucard still has his two normal cocks on his humanoid form. I also did a winger version & one other pic, considering I originally wanted to do something where he wakes & doesn't quite notice his body changed, until a few minutes later.

His reply would be something along the lines of
"You've got to be fucking kidding me. What the hell's going on here? Why did you do this to me?!"

Let me know what you gys think okay? It's my first attempt at a naga, so go easy on the critique or whatever. XD

And yes, Alucard still is retaining his cat tail, as well as his Naga one.
I also did a colored version as well. Perhpas someone could remeind me, considering I will probably forget to submit it. XD
