I should do a fix-it fic or a re-write of the Rooters Arc from Ben 10 Omniverse.
Osmosians will be aliens.
Kevin will have never been a Rooter.
But Devin would be.
My re-write would hinge on Devin’s death being faked and being with the Rooters. I haven’t decided yet if Devin would be a card carrying member, or a prisoner forced into helping them. But Devin will be a real person that exists and he’ll be alive.
Not sure if it would be a “rescue daddy” type story where Kevin (along with Ben and Team) would have to rescue Devin from Servantis. Or if Devin would not only work for the Rooters but be a co-leader with Servantis and it would be a “join the dark side” story for Kevin.
But Osmosians will be real aliens, Kevin would be half-Osmosian, and Devin will be real and alive.
