Super Robot (スーパーロボット Sūpā Robotto) is an old genre of anime focused on giant robot mecha with various super powers, special and flashy weapons, and the cliche of attack/special move naming.
It originated from Tetsujin 28-Gou from the 1950s/1960s and the Mazinger Z series created by Nagai Gou in the early 1970s. While not as popular as it was during its beginnings, it still continues to this day.
It evolved into the more realistic Real Robot (リアルロボット Riaru Robotto) anime genre started by Tomino Yoshiyuki's Mobile Suit Gundam in the late 70s and early 80s. This genre also continues to this day.
