He's a shape shifting demon.
Same character in my sig.
During a battle when against a very powerful foe, when attacked his form becomes less consistant.
In the strange 'staticy spiderman' looking picture, he has shifted his form to a corrupted version of my other character's body (Spectarius)
However, the more power he is charged with, the more and more he will resemble his true form (a giant dragon)
Basically, to make it simple.
He's fighting a sayain and going to get annihilated, so he half shifts to be like Spectarius, yet retains most of his demonic appearance.
If he is damaged enough, he is forced to change forms. And while changing forms, he is even more vulnerable.
