Ok hear out. Since his first appearance, I've always wondered about, how on Galvan-prime can Ben 10k keep track of 10.000 aliens? But then I thought while watching an episode of omniverse. Since Ben has the biomnitrix that allows him to combine two different aliens, what if he only had a hundred aliens and 10.000 is just the number of possible combinations.

Although I have no idea how that would apply to the previous 3 versions.

So, what do you think? Am i trying to see something that isn't there, or does my little theory have something worth thinking about?

Your idea actually makes sense tbh.

Makes sense
