ideon
The titular super robot mecha from the Densetsu Kyojin Ideon anime TV series from the early 80s. It was designed by Ookawara Kunio and Higuchi Yuichi from the Japanese toy design company Submarine.inc.
One of the most notable features of Ideon was the power of the robot, which was more powerful than anything else in super robot shows at the time, and still remains among the most powerful mecha in the entire history of anime (even now!).
