Okay , say if they were going to do a Manga of DC Comics ( Not that it's really going to Happen ) and they do a sketch of him . what will he look like and Why ?

He'd probably look the same in a in either.

depends on the artist, as styles can vary just as much as in any medium but here are two picture on found with just a quick search on the net:

and:

@kingjoker: Hm , Okay but I do remember I've drawn one picture of him and he looked a little like Frieza so what's your suggestion ?

@crom_cruach: You did ? well that's cool Artwork you got there Man !

Something like the second image. I think that would be a good anime look for him.

@kingjoker: me too .
