Well, DarkHenrik started a forum thread on a Ninjago remake. That's when I started thinking about a new series of Ninjago based many years after the current one. I thought it might be cool if the Ninjago creators stopped making new seasons for a year (or more) to get it across the viewers' minds that Ninjago was over. Then, a new series would come up, "Ninjago: Spinjitzu Prodigies".
The show would be based around the anncestors (or even just grandchildren) of the former Ninja team (thanks Sheldon Frank for some of these ideas), in the future world of Ninjago. Yes, since it's the future, there would be technologies similar to Season 3 available, but not many people would use them (there are planes, helicopters, some hovering cars, some vehicles with regular wheels, etc.). I like the idea of the elemental power dissipating over generations, so there are no more Elemental Masters. Still, the main characters are the heroes and protectors of Ninjago, but in the old fashioned Spinjitzu way. Every decade or so, the Spinjitzu Academy (I don't know what the name would be) would select young teens to come to the academy, and train in the art of Spinjitzu (a good amount of them may be the anncestors of the Ninja, but just because your great grandfather or grandmother helped protect the world long ago, doesn't mean that you have to) They each wear a different color uniform (or suit if that's the case), so there are about 6 of them (8 if there are two with a black suit and white suit), each with their own color spinjitzu.
Tell me what you guys think. I was also thinking that they could have vehicles that look like sleek and fast hover cars (that may even eject wings and boosters to fly).
