Why isn't there a villains category? Ben 10 and The Secret Saturdays have them, and there a plently of characters that are antagonists on this show.

Van Kleiss and Black Knight are notable examples. Did this page didn't have a villains category all along?

To put this in a sentence, the Omega-1 Nanite allows Rex to adapt to situations that would be fatal to him. For example, Rex is the only one who sense Breach coming in the form of creep out, while others are not. Thought you think that is just coincidence, it happened again and again, as well as the Block Party was the direct result of Quarry using the molecular destabilizer on Rex, as the weapon destroyed the atoms, or destabilize the molecule. Then the underrated adaptation is Omega EVO form as the result of fighting the consortium with 1/5 of the Omega Nanite, both separate and together. So, what do you think of the Omega-1 Nanite being able to adapt to anything.

Honestly, both the Generator Rex and The Secret Saturdays wikis have more or less been left to rot for the most part in recent years and I think it would make a lot of sense to have them assimilated into the Ben 10 wiki since their both confirmed to exist in the same universe.

Keeping it all in the same house so to speak
