1960s

It is arguable that the Marvel Comics teams of the early 1960s brought the biggest assortment of superheroes ever at one time into permanent publication, the likes of Spider-Man (1962), The Hulk, Iron Man, Daredevil, Nick Fury, The Mighty Thor, The Avengers (featuring a rebooted Captain America, Thor, Hulk, Ant-Man, Quicksilver), and many others were given their own monthly titles.

Typically the superhero super groups featured at least one (and often the only) female member, much like DC's flagship superhero team the Justice League of America (whose initial roster included Wonder Woman as the token female); examples include the Fantastic Four 's Invisible Girl, the X-Men 's Jean Grey (originally known as Marvel Girl), the Avengers ' Wasp, and the Brotherhood of Mutants ' Scarlet Witch (who later joined the Avengers) with her brother, Quicksilver.

In 1963, Astro Boy was adapted into a highly influential anime television series. Phantom Agents in 1964 focused on ninjas working for the Japanese government and would be the foundation for Sentai -type series. 1966 saw the debut of sci-fi/horror series Ultra Q created by Eiji Tsuburaya this would eventually lead on to the sequel Ultraman, spawning a successful franchise which pioneered the Kyodai Hero subgenre where the superheroes would be as big as giant monsters (kaiju) that they fought.

The kaiju monster Godzilla, originally a villain, began being portrayed as a radioactive superhero in the Godzilla films, starting with Ghidorah, the Three-Headed Monster (1964). By the 1970s, Godzilla came to be viewed as a superhero, with the magazine King of the Monsters in 1977 describing Godzilla as "Superhero of the '70s."
