The Mecha series was created by Mitsuteru Yokoyama; –Tetsujin 28-go was released in 1956. Yokoyama was inspired to become a manga creator by Osamu Tezuka and began publishing the manga in Shonen, an iconic boy’s magazine, in 1956. Additionally, Osamu Tezuka’s “Astro Boy” played a significant part in popularizing Mecha elements in anime, contributing to its early growth.

The genre’s evolution can be categorized into different eras:
1970s – The Rise of Super Robots
