As well as Albedo and the Emperor Milleous who previously were considered secondary villains and went on to become major antagonists, there are other villains that could acquire this role as:

The Vengers and Harangue: working as a team and recruiting all minors and secondary villains of the franchise, would become one of the antagonists more versatile for Ben, his team and partners.

LIMAX: they would be the perfect antagonists to be the principal instead of the incursians, since they have powers and would be lethal invaders to Earth.

Charmcaster: She will be weak physically but with his magic powers would be a worthy adversary and Ben would probably have difficulty in combat.

Chadwick: Being a mind teacher his alien abilities, would be the second eternal Knight to become a main antagonist and that would be it carrying out a truly destructive extermination plan. Dr. Animo: has been the antagonist most recurrent of Ben Tennyson and would not be a bad idea that was a main antagonist. But to do this, Dr. Animo would need to execute a plan of truly great mutation.
