Although the RX-78 Gundam is the most famous mobile suit from the original Mobile Suit Gundam anime TV series, it’s not the only giant robot the Earth Federation has at its disposal. As a matter of fact, debuting in the very same premiere episode as the Gundam is the RX-77 Guncannon.
Still, there’s a reason the series, and franchise, is called Gundam and not Guncannon. Aside from being slower and less powerful, the Guncannon can’t compete in the looks department with the dashing Gundam. Simply put, it’s just not sexy enough…at least not without this subtle variation to its paint job with a hidden significance.
