The first episode was particularly notable. Not just because it introduced the new characters and settings, but because it featured "Reptilicus," a 1961 Danish-American giant monster movie.
In the movie, a group of miners dug up a chunk of frozen flesh from a giant reptile hidden deep underground. The tissue eventually thaws and begins the quick process of regenerating into a living, rampaging monster dubbed Reptilicus.
Reptilicus quickly escapes and attacks the people and city of Copperhagen. It's quickly realized that nothing hurts him. They finally defeat Reptilicus by firing a mega-dose of sedatives into its mouth using a bazooka.
However, we quickly realize that the menace of Reptilicus might not be ended. A portion of Reptilicus was blasted into the ocean -- and promises to regenerate into a new monster!!
Which is what happened in the REPTILICUS comic book series published by Charlton Comics back in 1961. The comic book series last two issues before Charlton Comics lost the publishing rights. The publisher then repackaged the character and published a new comic book title called REPTISAURUS THE TERRIBLE, which lased from issue #3-8.
