Jetray will not appear in the first 40 episodes of Ben 10 Omniverse as he was 'overused' in Ben 10 Ultimate Alien according to Derrick.

It is not sure whether Goop will appear in Ben 10 Omniverse, but there might be a chance Goop will appear as he is still in the Omnitrix.

There is a high chance Ghostfreak will not appear in Ben 10 Omniverse as his appearances made in all Ben 10 shows are very less.

It is confirmed that Wildvine, Ditto, Benmummy and Benvicktor will return in Ben 10 Omniverse.

It is unknown whether Benwolf and Upgrade will make their reappearance in Ben 10 omniverse.
