He could fucking blow up any gundam known to Japan. Psycho Gundam? His deep fried, baby eating ways would be ended with a single boom. Heavyarms? Outgunned. Nightingale? Not big enough! The original Gundam? White devil gets killed by NRA Prime. Nuke Gundam? Toasted. Tallgeese? Gutted.
And GF Prime would eat the pilots too, just to show off his new face and faceplate.
