Gattai Robot Atranger

After years of stalemate in the war against alien invaders, the veteran robot Atlanger is finally being retired. Its farewell ceremony is interrupted when a gigantic spacecraft appears and launches an attack on Earth.

Atlanger cannot activate without the full complement of pilots needed to unlock its power. As the attack unfolds, young people attending the ceremony hear a mysterious summons in their minds: the robot itself is calling them to become its new pilots.
