Jetray: He appears in 'Ben 10 Omniverse: Game Creator', so he is sure to appear. Goop: His Omniverse Design Is Uploaded on his page. He is sure to appear. Ghostfreak: There aren't any current (07.11.12) proofs that he may appear.

The Halloween Trio: Benmummy was Confirmed to Appear by Derrick here: [1] Benvictor wasn't confirmed anywhere (07.11.12), and nor was Benwolf...

Wildvine: A picture of Wildvine (Omniverse) was uploaded by OmniPowerRangers. This confirmed that he will appear in Omniverse (Though its unknownn if he is for 16yr old Ben!)

Ditto: As said by Nick Fusion, " Ditto was mentioned by Teen ben once, so he might appear!" I also agree with this.
