This might be an unpopular opinion, but I personally think Ultimate Alien Ben 10K is stronger than both OG Ben 10K and Omniverse Ben 10K.

Here's why:

He has a fully completed Ultimatrix, unlike the glitchy version Ben used during Ultimate Alien. That alone gives him access to stable Ultimate transformations and makes him incredibly versatile.

He's a much better hand-to-hand fighter. Throughout UA, Ben became noticeably more skilled in martial arts, and that experience would naturally carry over into his future self.

He also learned to use mana, just like Gwen. Having both alien abilities and magical knowledge makes him a much more well-rounded fighter than the other future Bens.

The only thing I'm not a huge fan of is his ability to use an alien's powers without actually transforming. I still prefer seeing full alien transformations. That said, I have to admit it's a pretty unique and creative concept that sets UA Ben 10K apart from the others.

Overall, I feel UA Ben 10K doesn't get enough appreciation. He's easily one of the coolest and most powerful future versions of Ben in the franchise.

What do you guys think? Do you agree, or do you think OG/OV Ben 10K is still stronger?

Hot Take: I think UA Ben 10K is stronger than both OG and OV Ben 10K
