Hello, I would like people who know lots 'bout anime tell me if they can recognize this anime.
From as far as i can remember it started like this....
there's a ship in a space that is abducted by aliens and they're transformed into monsters of sorts. But then the father of the main character rescouses the main character and he goes to earth. and then they main character and the aliens fight.
more specific clues:
-An alien base was on the moon
-main character had to fight his brother
That's all i can recall if anybody has even slightest clues please dont be reserved
