Now, I know that for various reasons pertaining to the running of a business, only so many character designs will be created during a given span of time. Fine. This makes sense with the Omnitrix - Ben only unlocks a new alien on infrequent occasions - but this is ridiculous in relation to the Ultimatrix and Nemetrix:

1. Ben could turn any of his more than forty aliens into their ultimate forms, but somehow only did so with eight.

2. Khyber has a predator for nearly every Omnitrix alien, presumably about a million, give or take, but somehow only nine are ever used.

Why did others never appear? Which ones should have appeared?
