I am a huge fan of Marvel comic's Punisher MAX [18+] series. In it, the Punisher is free from the constraints of the comics code, leaving him free to do his bloody worst on the scum of New York in some very well written tales.
His appearance in the MAX line is much different than in the regular Marvel universe. The sharp Punisher logo is replaced with a crudely drawn white skull is smeared on a black flack jacket [makes more sense, Frank Castle is not an artist.] He is over 50 [he was in Vietnam] and his face is creaced with years of scar tissue, his nose is broken and he is overall taller and more muscular. According to artist Lewis Larosa, he is 6'3 240 lbs of vengance in a leather trench coat.
I saw the Undertaker figure in KB and knew he would make a great MAX Punisher. Cut off his goatte and beard, cut his long hair, and scared and resculpted his face and "broke" his nose, slapped on a Skull and 2 holsters and gave him the Spiderman 2 Doc Ock's hands [they still have wrist articulation] and we have Mr. Frank Castle
