Herms, I might have a contribution for the Name Pun Guide.
In Movie 8 you have Moa (モア), who is the guy Paragus kills after he reveals to the audience he's waiting for the comet to come and destroy New Vegeta. While this doesn't give us a clue about the name origin, you asked in that thread for us to remind you who this guy was
Anyway, Heroes comes into play. There, they added Moa and one of the soldiers that were making the slaves work and then got scared off by Gohan and Kuririn. His name is Angol (アンゴル).
Now, if you join both names, you get Angolmois (アンゴルモア), which, supposedly, is a Great King that would have been ressurected by another Great King that came from the heavens to bring war, as predicted by Nostradamus. This might vary depending on translation and interpretation, of course.
So... he might be Mois? It kinda fits with the comet coming to destroy the planet and maybe with Koyama's interests.
Keroro Gunsou and other series also use this name.
Edit: Sorry, this has already been discussed.
