When I was coming up with ideas for the Devil Trigger series I came up with the idea that when ever Daniela used Beast Mode her condition would become more unstable, (kinda like Godzilla in Godzilla vs Destroyah) until at the finally when her transformation is the most unstable.

when coming up with ideas for a design for this form I went with a more "fiery" color scheme with the Blues and Greys being completely replaced with Reds and Oranges. And with that the black-light image for this peice became very "vibrant".
