This is my first time drawing GB! Gaster transforming, so... yeah...

Probably looks more like a normal transformation than a mutation, but whatever. :P

God, why does his lab coat have to be white? It makes it so hard to see little details... :/

Oh well. Who cares?

EDIT: lokiplayz I finished my Usakai! :3

I'm going to digitalize him eventually, and the lighter blue is gonna be way more gradient. Plus I'm gonna lighten the colors a bit as well. I just did this real quick with sharpies. :P

Hope he looks okay!
