In the future they should make episode that shows what exactly happened during the time war because of this episode we know that ben helped ben 10k. If they do they could show kenny and ben 10k aliens like Shellhead,Snakepit,Sandbox, and Atomix.
They should not make an episode about this. They should make several episodes about it. To actually do a time war justice, it needs time to unfold; more than a single episode can give it. But if they will not do multiple episodes, they should not do it at all.
I think that they should make a whole season out of it. They could do several episodes with Vilgax, and then several with Eon. Then on one of the last episodes of the season, have Vilgax meet up and agree to take revenge.
I hope there is a universe in which Gwen keeps the charms of Brazel and turns evil. When she was contemplated what to do with it and thinking of keeping it, she sounded kind of evil, similar to Ben contemplate using all the combine power to rid the world of all evil in the final episode of UA.
i actually love episodes with time travel. because i like seeing bens, and gwens present, future and pass selves. Because i kinda miss some of their younger selves, and also wanting to see more of their future selves making appearances in the franchise. cant wait for the vilgax and eon time war event. i saw in that page gwen 10 will appear i guess. gonna be interesting. and imagine all the bens.
