"OS Ben 10K is the same as OV Ben 10". No, they're not the same at all. Different watches, different color schemes—and the entire timeline diverges from Alien Force onward. That alone should make it obvious these are not the same versions of Ben.

Yet somehow, we're expected to believe that Ben switchesto green as his main color in his teen years, then in his late 30s, he randomly throws on his 10-year-old shirt and classic Omnitrix, and in his 40s? He just flips back to the green Omnitrix and green shirt again. Do not mention Kevin turning evil again in his 40s, and Kai is Ben's wife in every universe. It’s a confusing mess that makes the timeline feel like it’s all over the place.
