I would have no idea... I have been through so many ideas, from ninja reborn like to undead dragon type to now a more cunning type warrior...
Honestly if it possible to use a skin starting from one of our skeleton skins, and transform it a bit, giving it backlooking horns, and add wings to it, that would be awesome, as i would dream it, but i think it's very difficult to add something like that, it may come relatively close to the general Grevious Skin.
But yea, i think my skin is untouchable to try..
A undead Dragon skin with wings.
Well, might as well try asking lolz..
