I recently got rather invested in the character Gaster from Undertale. As I was thinking, I came up with the idea of Gaster, but he looks like a humanoid version of a Gaster Blaster. Also decided to have Sans and Papyrus look like the same species because why not. Pretty much a boney dragon-like creature who's true form, which they can turn into at will if they desire to, is a gigantic, wingless beast-like being. But, to better fit in with society and to fit into places better, they tend to use humanoid forms that are taller than some monsters but smaller over all than their true forms. I like to think that Gaster has a ability to switch between magics as well. Like he can use yellow magic to shoot bullets from his finger tips. Orange magic to harm speedy or jittery opponents. Purple is either a force field or a concentrated blade, not sure yet need to research more on the idea. Green I haven't figured out yet either, probably barriers? But his primary magic that he'd use the most is blue magic and orange magic, blue being able to grab and throw and hold the very soul of a being thus pretty much holding them. Of course it's a concept but it's an interesting one. Normally his eyes only change color when he uses said mentioned magics, otherwise they're white in coloration. I drew both his pre core incident form and his post core incident form and even his true form a little. He's pretty goopy in his post incident form so even though he looks like melted ice cream he'll reform himself once he manages to stabilize his form enough.
At any rate, this man has been stuck in my head for the past week, both in normal form and in this Gaster Blaster au type idea. Going on two. So uh, there may or may not be more with other characters. Maybe.
