This is my take on what Dan would look like after he got overtaken by the elemental energy. I just HAD to use the black and red tendrils that were all over the place when he and Drago were being overwhelmed. 

This is him when he's not in combat! I took some inspiration from Faustus, Magnus and Benton because I think Dan would actually respect them a lot! 

And this is what he looks like when he's in a brawl. Unlike his uncorrupted self, this Dan uses a whip to attack his opponents. 

Any critiques?
