With a new film coming and current comic book from BOOM! Studios King Kong is quite popular but he has been part of the comic book world more then some my realize. Some of those apprearances came from Marvel and DC Comics, Kong made multiple appearances in the Marvel Universe, one as a giant robot ape called "Kong" appeared in Nick Fury, Agent of SHIELD #2 in 1969, drawn to look exactly like the famous movie monster. The character Warlock from The New Mutants turned into Godzilla and then King Kong (one of those interesting trivia fact) during a rampage through New York City in Web of Spider-Man Annual No. 2 from 1986. In Webspinners: Tales of Spider-Man No. 1 from 1999, Peter Parker is seen watching the film King Kong at a cinema alongside Quentin Beck. He would return to watch the film again in issue #3.
For DC, he appeared via a poster in 1961's Adventure Comics #289. In that comic's back-up strip called Tales of the Bizarro World, Bizarro encounters Titano on Earth's prehistoric past. When he returns to his home world, he's inspired to make a TV series based on the character only to be accused of ripping off King Kong. King Kong appeared as a statue in Superman's Girl Friend Lois Lane No. 73 in 1967 and as a robot brought to life (among other giant robots in an amusement park created by Toyman) to fight Superman in Adventures of Superman No. 475 in 1991. In issue No. 226 of Superman in 1970, Clark Kent is seen watching the film King Kong at a Metropolis cinema and after being exposed to Red Kryptonite (as Superman) grows into a giant who rampages through the city in a story called When Superman became King Kong!. In issue No. 120 of Weird War Tales from 1983, G.I. Robot encounters a giant female ape referred to as "Mrs. King Kong" on Dinosaur Island who saves him and his allies from a Tyrannosaurus. In 1985's Blue Devil No. 15, Blue Devil battles a giant robot King Kong that malfunctions at the "King Kong Attraction" located at the "Verner Bros" studio in Hollywood.
