Armor like Devil Trigger kind like Nelo Angelo's.
I also would like wings - bat like ones, but like in Dante's Devil Trigger I would like them to appear/spread only when I wanted them to.
Colour dark blue. Easy to hide in shadows.
Additionally some Vampire/Devil characteristics like different teeth or ears. Of course different eye colour. Crimson perhaps.
A cape/trench coat would be nice also - again idea stolen from Nelo Angelo's design.
I wouldn't like horns.
Changin skin colour - paler.
And perhaps altering the hairstyle to go one with demonic style.
I wouldn't like bigger nails either. And not so many uglying factors. I mean, how come Trish's appearance is cute? Devil's can be nice in appearance:lol:
That's all I guess..
