as I unashamedly love Reptilicus (1961) I was very interested in the comic book from the same time period.
Charlton issued a total of nine Reptilicus/Reptisaurus comic books. it seems an odd thing to try to market, but they also did Gorgo and Konga. since I don't care for Konga, I've never read one of those comics but Gorgo ran 26 issues.
anyway, Reptisaurus features some decent art and interesting stories. eventually he becomes sort of a good guy monster and even gets a mate. possibly from the claw in the movie, I don't actually know. Reptisaurus doesn't actually look too much like his cinematic forerunner, but that's OK, he's more impressive in 2D than in 3D.
there's a new movie called Reptisaurus (2008) which has gotten some decent reviews. I'd like to see it, but I doubt it could possibly live up to the original or the comic book!
