The father side of Jrogenshin's powers. This transformation would have to be called....Negagon
It's called that because for obvious reasons: Jrogenshin is also half dragon/human but becomes a dragon in this state. Also, he has negative effect with his Aura powers which draws aura from everything around him which causes them to either weaken or die and increases his own powers as well.
He has dragon wings of course, but I just can't draw them very well x3
(edit: srry about that folks! It seems to me that it's a tad too dark....I'll fix it up)
