About the only ten predators bit: I've suspected that the Nemetrix may have some sort of automatic limiting mechanism, sort of like the one that applies to Ben. After a predator form is unlocked, it can be used freely, but in order to do so, Khyber must specifically unlock it. It would exist as a failsafe for when his pet is transforms independently or when the Nemetrix malfunctions, as it did in Outbreak, the idea being that too many transformations would be detrimental when not governed by a guiding intelligence, so the Nemetrix is automatically limited only to forms that have already proven useful. The one exception I can think of that could potentially disprove this would be the appearance of Hypnotick in Malefactor, though it's possible that the form had already been activated in a training exercise or the like. This would explain why Khyber only summoned ten predators: they were the only ten unlocked and it would take additional measures to summon more, especially when he was calling upon several anyway. I guess it sounds like one of those fan theories, but I think it's reasonable.
