Mobile Suit Gundam

I built Gunpla before I watched any of the anime. Mixed and matched mecha with other leftover weaponry. I just liked how the mecha look. People tell me things like, oh, they don't have beam weapons in IBO, etc, but I don't care. It's my build.

You don't need to have seen any of it to get into gunpla.

That said, you should watch the 3 movies that summarize the OG Mobile Suit Gundam, then Zeta Gundam, then Char's Counter Attack, just because they're all bangers.
