The original Gurren Lagann.
This comes no where near too a good troll attempt.
If anything Getter Robo was the original GL. But Getter is just a rip of Nagai's earlier Mazinger which is just a rip off of off Gigantor, which is a rip off of Astro boy.
Astroboy is a ripoff of Mickey Mouse.
The original Guyver.
I'm not trolling. I'm absolutely correct.
Rip off or not Getter Robo >>>>>> Mazinger and Gigantor
