So I was watching the latest episode of Gundam Build Divers Re:Rise
The MCs have to protect a planet called Eldora (possibly borrowing the name from to El Dorado) from bad robots, who came from the moon, and The MCs managed to fight their way into space.
In Space, they found out that the Moon is not a moon. It’s a giant DEATH BEAM DISPENSER, and it’s aiming right at Eldora! Fake Moon ended up firing its death beam at it.
And then it hit me: maybe Eldora wasn’t referring only to El Dorado. Maybe it’s a hidden Alderaan reference.
