Grendizer: What? And what for?
Gundam: Come on! You never run out of ammo or power! You pull out swords from all over your body and you shoot massive disintegrator beams! You are unable to use a normal rifle! You shoot your fists! YOUR. FISTS!
Gundam: And then all those impossible transformations and your approximate design! It is hard to understand even how you can bend your joints!
Grendizer (bending its forearm): Hey! It's right!
Gundam: Giant monsters and horrible aliens! Endless Fanservice! Incredible plot twists and collective laughter at sunset! Come on...!
Grendizer and Gundam: Hahahahahaha!
Grendizer: In short, you're envious...
Gundam: To die for!
