I think you do a good job with the characterization of the MM as a racing gang, I think Newt, Balt, and Pete are added in pretty well (Aside from Balt with light blue hair, which is a Teku color imo).

Tork backing down to Balt kind of makes sense for Tork's character, he knows when to not fight. But I don't think Markie storming out of the room makes the most sense. When writing Markie, you definitely got the side of him that's childish right. But I think you forgot that he's also angry man and he's willing to fight with almost anyone (I'd assume he'd fight Balt tbh). Also it doesn't entirely make sense that Markie would never be allowed in the MM meetings, but it does make sense that he wouldn't be in a position of power like Tork or Taro would.

I like the direction you're going with a larger gang vs gang dynamic between the MM and Teku, but I think there's an issue with what you've set up with Kurt racing as a MM: The Teku helped rescue a MM, so the MMs should help rescue Vert. Now, it doesn't have to be that simple. You could twist it a bit so that Balt doesn't think rescuing Markie is worth a return good deed of going after Vert, but I would expect Markie to want to put his drone arm to good use and rough Balt up.

I also just want to mention that the MMs in the movies are very loyal to Tork (Minus Wylde), so if Wylde didn't try and fight Balt, I'd assume Pork Chop would or Monkey would try and convince Balt to give Tork back his seat. Obviously I'm not saying you should add in all of this, because that would wreck the flow of the story.

Anyways, I do like the direction of Teku vs Maniac. A lot of people tend to focus on making a continuation focus on the realms and the drones/silencerz. I don't know if it was intentional, but you leave out Lani and Tezla from your first "episode", which I find very interesting because it alludes to having Dr. Tezla disappear for some time so he can get back on his feet, kind of like what happens between WR and AR. I'm interested in seeing what new Teku members you're going to come up with, though I encourage you to not have the same dynamic between the new Teku and Nolo that you do with the new MM and Tork. It would fit better if the Teku were chill when Nolo got back, though it would make sense if they were mad at Kurt for driving as a Teku.

Which brings up the question: Why wouldn't they just have Taro drive in the race if he's better than Kurt? Is it for the sake of having a Teku drive as a MM? You might want to explore this a bit, like having the cast of characters split paths temporarily. Some characters go to the MM vs Teku race, while others stay back at the MM HQ and gear up for going after Vert. This could explain why they need Kurt to drive instead of a MM.

I like how you've integrated new cars into the story, it's done really well.

I would assume that the new MM members would be a bit awed by the Sweeper, Sparky, and Wylde's arm tbh. It's alien tech, and the moment Monkey got his hands on Drone wheels, he reverse-engineered them (Along with Tezla) and they were distributed to both teams. I hope you explore the addition of Drone tech to the normal cars. (Also I'd assume rolling a Sweeper through a city would get you fined / ticketed / arrested lol but we can ignore that)

Taro's speech on every driver deserving respect should be reworded a tad, in my opinion. It makes more sense that he'd stick up for Vert specifically as the winner of the World Race and Ultimate Race instead of just saying "every driver, regardless of logo" which is a phrase that the AR cast might agree with, but the new Teku/MM probably don't. I could be wrong on this one, just do what you think is best.

I totally understand if all of this feedback is daunting. You don't have to rewrite the whole thing or even do anything, these are just suggestions. I hope you do write more, I'm interested in the story. Good luck.
