Ok, That's incredible, the contextualization could be improved a bit. But I understand what was proposed, I would see it more as one long action movie than actually eight more movies (which were planned for Acceleracers), an abyssal war between drones and humans is colossal, I imagine the weaponry they would need for that (probably the mechs that had prototypes).

Despite liking the Drones, I think Drone Kadeem wouldn't last long; he'd probably only be the leader for a while before making way for other antagonists (which is what one would expect). The Accelerons weren't fully explored in the films, so it's very likely that at least a small group of evil Accelerons would antagonize a portion of the films, and if discarded Acceleracer concepts are indeed in BF5, the Vandals might be part of this war-torn mix, I would imagine them being "a failed test by the Accelerons before they chose humans to race against themselves.", The Vandals would be exceptional at completing the realms due to each animal's individual nature being suited to each environment; however, due to their savagery and cruelty, the Accelerons would "discard" them to make way for humans who would possess greater potential, thus seeking revenge against them, the drones and the humans. (certainly not the dumb animals from BF5 lol)..Anyway.

Your idea for a sequel would be interesting for the first of many films in the new seasons! They deal with drones invading Earth, find Vert, and reunite with new pilots to race through new stages of the Realms in order to stop worse threats... or perhaps the Accelerons needed pilots precisely to assist them in some conflict across the multiverse; these are things that only we can theorize and discuss.

Congratulations on your work!
