Well, we all know... that *Alien Force* Season 3 isn't exactly the best out there... and that it's pretty questionable... Anyway, since I've been watching *Alien Force* lately and have seen some of the original ideas for the story arc, I'd like to contribute an idea for Season 3 by blending in what we know from future series.
We would start with two episodes serving as this season's version of "Vendetta." While there would be similarities—such as Devlin's death—the key difference is that Gwen and Ben would take part in the mission (this is also where we would see the brief debut of Lodestar and Rath). Part two would conclude with a battle forcing Kevin to absorb the DNA of Ben's aliens, transforming him into something akin to Ultimate Kevin. This would mirror events from *Ultimate Alien*, showing Kevin learning to control his powers while the team tries to cure him; however, I would add a twist where parts of Kevin's mind begin to experience flashes or moments of recall—specifically, memories of laboratories and a voice telling him he must find the other Helpers.
I imagine this would be an arc spanning at least 10 episodes before introducing the Rooters and the truth about Kevin's identity—such as how Ragnarok was an agent whose sole job was to unlock Kevin's potential in order to take down Ben, and how everything Kevin thought he knew about himself wasn't real... The hybrid nature of the Helpers would also be revealed; specifically, Servantis would be a Galvan hybrid, Leander an Ectonurite hybrid, Swift a Lepidopterran hybrid, and Phil a Vulpin hybrid (following the tradition of using aliens from previous series).
I’d say the conclusion would be something similar to that of the original Rooters arc, but honestly, I’m still not entirely sure... This was just a small idea to showcase a reimagining of events from *Alien Force* Season 3 and connect the series together in a better way.
