The true form of Mr.Dark.....His metarex form. Mr.Dark was once a Metarex Commander, and a very powerful one too. As a metarex, he is known as Dead Black Willow. Also, those black spikes you see on his shoulders and back....they're not so much as spikes as they are barbs. Although the ones on the arms and legs are more of spikes. Just so you know, he is supposed to be of a pitch-black color. Although, I can see a nice purple working just fine....I hope you enjoy.
