Char couldn't beat Amuro's Gundam in the final battle with the Zeong, and in the end he said, "Become my comrade," which is pretty selfish. Haman said something similar, and the Dragon King said he'd give him half the world if he became his ally, so I'm sure it's the final boss's catchphrase. Now, speaking of kits, I think the biggest gap between RG and HG is the Zeong. It's almost a collection of new interpretations, but the details have been arranged so well that it's slim and has a small face overall, and when lined up with the HG it looks like a before and after of the Rizap. When it was released, there wasn't much competition, but there was only one normal one and one with effects, so it was a bit of a challenge.
