He also created "Shade the Changing Man" and "The Creeper", I never had enough of those comics, not to mention Dr. Strange and a legion of other comic books.

I think that Steve Ditko had no equal.

I saw all of his comic characters, well, I saw most comic book charaters out-there period and Steve Ditko had no peer(s), he was in a level all by himself.

Ditko's comic book charaters and stories were just so special and unique and very much unlike most of the others, they had a very special flavor.

I think that only Jack Kirby was almost as great as Steve Ditko:
