Hahaha, oh wow this is just awesome. And really freaking obscure.
As you may know, the newest Gundam series airing now is Gundam AGE. One of its gimmicks is that it'll take place over the course of three generations of pilots, with each generation getting its own gundam(and each gundam has three forms, ergo nine models for Bandai to sell).
Now, one core part of gundam is Newtypes. I won't go into details, but they're basically space psychics whose abilities allow them to fight better than normal humans. We've had rehashes of them in Coordinators an Innovators, and AGE is no exception. It has X-Rounders. Sounds silly, right?
Well, maybe not. As you may know, Mobile Suit Gundam was directed by Yoshiyuki "Kill 'Em All" Tomino, who has a lot of experience directing giant robot shows. Back in 1975 he was a rising star in the animation industry. In 1977, he made Zambot 3, a very low-budget anime often made by only 3 or 4 people because they couldn't hire any more people. Why did a rising star get such a low budget two years later? The answer lies in the year between, of course.
Back in 1976, the pilot episode of a new Tomino-directed show hit the air. It was a one-hour big budget extravaganza, featuring a battle between an Earth-based faction and a space-based one, fighting with space-psychics in giant robots. It was a realistic take on the concept and possibly due to that, it bombed, with no other episodes getting made, and all that remains of it is 20 badly-recorded minutes. This was not Mobile Suit Gundam, mind you.
It was a show taking place over the course of three generations of pilots, and it was called X-Rounder.
