I really liked Aggregor and the Highbreed. Aggregor was a pretty serious threat, and instead of having henchmen or minions, he preferred to handle things himself.
I liked how the Highbreed were an entire race instead of one character, which IMO was a cool way to raise the stakes at the start of AF.

And if I may on Khyber, I believe what Tyranidomega meant was because of Khyber's limited appearance he did not live up to be a serious threat that Tactical Ochoa thinks he could've been.

Have to ask Tactical, how would you have Khyber grow to become a serious threat? I have some ideas myself, like maybe he resorts to kidnapping one of Ben's family.

@Tactical-Ochoa You make a really good point. Khyber actually had a chance of becoming a serious threat, for one reason: the Nemetrix. I agree with Tyranid's point on the Nemetrix, a unique concept where the Omnitrix aliens had natural predators that either countered their powers (Terroranchula, Hypnotick) or simply overpowered them (Tyrannopede, Slamworm)

There was actually a concept idea of a predator for Waybig-here

It would've made for a cool episode where Ben was stuck in Waybig for some reason and was very ill. This could've been the equivalent of Khyber poisoning Ben. Would something like this have made Khyber a serious threat?

@Tactical-Ochoa Is it okay if you direct link me to the writer's page? You only have me the Fanfiction home page.

I'm currently hooked on this crossover with a manga/anime right now. If you're curious I could tell you it but what Ben 10 fanfics have you checked out?
