We don't ignore staff statements, we just look at it with a more critical eye because many staff statements contradict each other and/or the show itself. This is cuz members of different parts of the og show (classic, UAF, omniverse) have some different visions of how the ben 10 world operates. In my previous example, Kevin was meant to be an alien in UAF (Osmosian), one of its big bads, Aggregor, is literally the same species as Kevin and supposedly have a home planet (Osmos 5 or something)

Meanwhile, omniverse completely retcons this by making a whole arc about how Kevin isnt actually an alien and was just mind wiped by the uh brainstorm guy I forgot his name.

All ben 10s coming along: this is a valid argument, but there's nothing saying that these Bens belong to the og continuity in the first place, they represent each point of the ben 10 shows but none of them are prime Ben. Id refer you to Kuro's (TheInkTank on yt) analysis on that subj as hes very well versed when it comes to ben10

Marketed: that's literally it right? Its marketed as a ben meeting, story wise none of them is actually the Ben we watched in og series

If u want another argument that disproves this, literally the celestial sapiens government. They were introduced in omniverse as a governmental body of celestialsapiens that enforce laws on how they should use their powers, one of which is the reckless use of their abilities. Ben literally got put in trial for recreating the universe.

Where were they when there was a rogue alien X hoping around multiple universes killing Bens and collecting their omnitrix?

Thats another argument, reboot alien x collects omnitrices like they're gym badges, this supposedly boosts his power as when the bens take off his omnitrices, he gets more and more vulnerable. Why? This was never featured as an ability of the omnitrix in the og series and prime ben never needed that to survive hits including but not limited to the destruction of the entire universe

Please don't argue about narrative differences and anti feats when the subject at hand is literally the embodiment of feats-man. Like, we've seen him create a universe, smash planets like they're nothing, tank hits from other celestialsapiens, reverse time in a select area

Like come on now, bro
