This is a 1977 mecha show where two pilots combine into a giant robot to fight an army of resurrected dinosaurs, and it plays that premise completely straight. The formula never changes: dinosaur attacks, team scrambles, Lamees and Kamal merge, Super Aizenborg wins, repeat for 39 episodes. It's the platonic ideal of what a Saturday morning toy commercial looks like when you strip away irony and just commit to the bit for an entire series.
Dinosaurs long assumed to have died out have come back, and their rampage is bringing disaster to Japan. In response, a special squad of expert fighters known as Aizenborg is created. Two of its members draw on special powers to merge into a giant combined warrior and battle the villain commanding the dinosaur army. The TV series runs 39 episodes and blends mecha action with science fiction.
