SD kits like these nearly all come from Superior Defender Gundam Force (or Mobiile Suit SD Gundam), though I can’t remember if this one makes an appearance or not. Quite a few appeared in short comic strips after the anime stopped.
My RX-78-2 First grade kit bash. can anyone tell me what its kit bashed with, I have the box but I don’t know what series its from. the box says 1993, I didn’t even know there were SD series that old.
