Is Muteki-Ô Tri-Zenon coming back?

The show has ended. Muteki-Ô Tri-Zenon concluded its run on March 24, 2001, after airing 22 episodes on TBS.

Muteki-Ô Tri-Zenon was an action and science-fiction anime series that first premiered on October 14, 2000. The story was set in a future where a large emigrant fleet called Zenopares arrived from a star 10.8 light-years away, attempting to invade Earth and make it their home. The series depicted the Earth's struggle against this invasion, highlighting the efforts of three ancient space battleships and combat robots sent to oppose Zenopares, which had been implanted into a clan on Earth and disappeared into the planet long ago. The narrative followed the clan's awakening in Japan in the 2000s, as they fought to defend humanity when conventional arms proved ineffective against the invaders.
