Ken 10 Omniversal Journey
The story I plan to write goes as follows Aggregor escapes from prison in the Null Void having regained his powers. He tracks down Devlin Levin and steals his powers and makes his way to Galvan Prime.
Upon Aggregor's attack on Galvan Prime the Tennyson family and friends attempt to stop him. Aggregor manages to get what he wants and escapes on a ship only for Ken Tennyson, Devlin Levin, and Ken's pet Winston to pursue the Osmosian with a high-tech Galvan ship despite Ben and the rest telling them not to.
Aggregor uses what he stole to open a gateway that both he and Ken's group end up going through. They are now stuck outside of the Ben 10 multiverse and travel to other franchises.
THE TEAM
Ken Tennyson:
Son of the hero Ben Tennyson and Kai Green. Ken after the events of Omniverse was grounded from hero duty until the threat of Aggregor had returned. After getting back his Omnitrix Ken worked alongside his family and friends to track Aggregor down.
Devlin Levin:
Son of Kevin Levin and a human woman from the Saturn colony. Devlin's mother was a close friend to both Kevin and Gwen. When the woman wanted to have a child she went to ask Kevin to be the donor. After talking it over with Gwen, Kevin agreed, thus Devlin was born.
For the next eleven years, Devlin grew up only ever hearing stories of his father as Kevin was kept preoccupied with saving the universe. Having grown tired of not ever meeting his dad Devlin traveled to Earth to find Kevin.
Wandering around South Dakota Devlin eventually meets Ken Tennyson and the two bond. Later on, Devlin helps Ken fight off a group of aliens and upon learning who he is related to takes him to Ben so they can get in contact with Kevin.
The two finally meet and while Devlin is in trouble for running away from home Kevin takes to Devlin. Devlin starts staying with Kevin every few months and hanging out with Ken.
Devlin inherited Kevin's original transformation as his Osmosian ability. However, after encountering Aggregor Devlin lost this ability. Thanks to Albedo Devlin now wields the Optimized Omni Matrix or Optitrix. The device was made from Albedo's Ultimatrix and works just like the Antitrix from the reboot.

Albedo:
Former assistant to Azmuth Albedo was one of Ben 10's greatest rouges. However, after his capture during the episode Malgax Attacks, he spent the last thirty years in a Galvan prison serving an indefinite sentence.
After Aggregor invades Galavan Prime Albedo escapes his cell and attempts to take off in an advanced ship. However, the Galvan soon found himself caught up with Ken and Devlin's adventure. Thanks to traversing through the omniverse Albedo was able to regain his true form at the cost of permanently losing transformation abilities.
Now reluctantly working alongside Ken and the rest Albedo serves as the resident genius. He spends most of his time working on the ship and building inventions to help them survive these new unknown realities.
Winston:
Ken's pet rock monster from Legerdomain, Winston was given as a birthday gift to Ken by Gwen Tennyson. Despite having the sapience of a dog Winston can be rather intelligent at times and usually understand what's going on around him. Thanks to Gwen's powerful magic Winston will always be all to piece himself back together.
I hope you all liked my story Idea, I appreciate all feedback as it helps me write so feel free to let me know what you thought of it. If you have a world they should or want them to go to first let me know. However, one rule is that the worlds you pick have to be outside of the Cartoon Network collective multiverse so know shows made by Cartoon Network like Samurai Jack or Generator Rex as Professor Paradox can travel to those.
