Usually, I know a lot about Gundams, and this is going to be extremely geeky sounding, but Which model of RX-78 IS that?
I mean, it kinda looks like Mudrock (Rx-78-6), but Mudrock used 2 300 MM Cannons and was primarialy Blue instead of Red, and it didn't have that odd Punch Dagger weapon.
The legs look kinda like Musha Gundam (Dynasty Warriors Gundam), but even those are wrong.
Is it supposed to be a new Gundam Model they are releasing or something?
Perfect Gundam is the RX-78-2 with extra armor and weapons on it similar to the heavy_full_armor_gundam. It's from the manga Plamo-kyo Shiro which is about 25 years old.
