What is the Problem with Ben 10 Alien X tinction? 

Very true. It's unfortunate that people just can't enjoy something from the Reboot, solely because it's from the reboot, or that they have to nitpick things that aren't exactly the same as they were in the original. And ye with my Ben 10,010 video the main point I'll be discussing is the one that you brought up.

I didn't watch the reboot so I don't know how does Ben reboot behave there. But in Alien X-tinction he was unbearable, the whole special he kept repeating how he can defeat Alien X alone despite being defeated by him using multple aliens, he also kept asking for his watch back. Honestly I expected him to learn humility, I thought that was going to be his development, but I can't say he got a proper development, from what I recall, he was fully against teamwork (unless it was alongside his variants, because he thinks he(they) are cool) but in the end he was the voice of reason that suggested for everything to team up against Alien X. What made him change his stance? I don't know. Which goes to another problem I had with the special, why are the Bens there? I thought they gave Main Ben a terrible actitude, so he will learn from his counterparts, that are more mature, since he doesn't want to hear others, but probably will hear himself, but his variants weren't that much better, just less annoying. And they also had an opportunity to develop Ben using his evil future variant. Their backstories are similar, both wanted to believe they win every fight alone, that they didn't need others, they could use the backstory of the Evil Ben to show Ben what path is he building for himself, so he decides to change and be a better person, and that's why in the end he decide to add Gwen and his grandpa to the team (well the idea needs to be polish, but you get the concept). Instead we learn the villain backstory when Main Ben already decided to be pro teamwork. Honestly I didn't like this special, that being said, I watched the movie, and despite they giving Ben a similar behavior, I think they developed his journey better there, and I actually enjoyed it

@@FranciscoRamirez-nb4uu ye I did find Reboot Ben annoying in this special and times didn't understand why he would do or not do things. As for why Reboot Ben changed his stance, that's probably because he realised that what he was trying wasn't working so he needed to come up with a different way of fighting against the celestialsapien.

It's possible that only Omniverse Ben was prime Ben and that all the other Bens are Prime Ben's past selves, but because they're from past timelines, they can't be from the prime timeline. I already covered in the video that UAF Ben did know who Alien X was. Unless there was another time in the special that I'm forgetting.
