The funny thing is OV makes it a point that mythical creatures like Zombozo and Subliminal , the Omnitrix don't need explaining and takes away the mystery of them and there fairy tale roots. Yet OV is told and executed in such a tell tale way that none of the mystique ends up existing anyways.
For example Rook's planet and roots are explained in one episode, the fact the creators have no interest in the story meetings of doing more about Rook proves, there just hashing planet after planet, alien after alien in order to supposedly flesh them out but it only enforces that there just monsters and roleplaying toys. It's uninspired to not let kids imagine anything about the aliens,
AF/UA tried to go the other spectrum of the original series. Make it more scifi focused using things like Primus, Blood Lineage to flesh out the world, as well as using handles and staples of classic scifi Green Lantern Ring=Omnitrix. For example OS Zombozo is more about the image of haunting ring leader, a supernatural clown, ghostfreaks equivalent but that's basically his gimmick, a good gimmick from something like a horror movie but a one off villain at best. Zombozo in UA isn't as mysterious as he was in the original series but it's replaced by genuine threatening demeanor, and a different portrayal of a mad clown. There's nothing scary or about OV Zombozo, he has the creepy smile, but he ends up being a joke villain, theres even LESS mystery to him now because he's JUST a gimmick villain with no haunting image or fearful imagery, he also looks like something from the old beetlejuice cartoon.
Primus is another example, it is a way explain the omnitrix which seems tell all but then the way it's executed, it gives Eunice and the Ultimates a planet to live on and it can give an explanation about pure dna separate form the omnitrix, it feeds a tapestry and can be played off in future episodes. AF/UA decides to turn the board over, explaining something like the omnitrix renders the concept dry on the surface but it gains several things in it's place a creates a bigger mystery, think LOST
Dwayne once said that you should feed the fans who want answers to the omnitrix but don't overfeed them.

Undetermined. I came very close to naming them recently, but it felt digressive.
That's what OV feels like as a total, digressive and telling things we don't need to know. It's like when you make a James Bond movie and you explain things like his gadgets that were left intentional in the dark. It adds nothing to the mythos other then be a popcorn movie. The next Ben 10 team will have a hard time making a story in a universe where everything has been told.
