Information on the location
Titan is a fictional location appearing in American comic books published by Marvel Comics.

It first appeared in Iron Man #55 (Feb 1973) and was conceived by Jim Starlin and Mike Friedrich. The Titanians, also known as Titans, were later retconned as being an offshoot of the Eternals, which had been created separately by Jack Kirby.
