Ultimate Alien-era Ben 10 to the Pokemon World

Well, once he finds out that Ben's not a Pokemon and apologizes for the mishap, a friendship could form. That said, he'd likely be hellbent on capturing the Ultimatrix bearer before that.

And given the sheer scope of abilities afforded by Ben's various transformations, he'd make a high-priority initial target for Ketchum.

Obviously, Team Rocket's goal of capturing Ben won't go away anytime soon. If they're so obsessed with obtaining Pikachu, then they'll almost undoubtedly go after Tennyson.

Initially, though, Ash probably wouldn't know that Ben in alien form isn't a Pokemon. And an essential element of being a top-tier trainer is capturing them, so that'd drive his initial goal before he realizes that his target is "merely" a human boy from another universe, with a wristwatch-like device that can turn him into superpowered extraterrestrials. Super cool, huh?

I doubt it, considering he ain't a Pokemon no matter which alien(s) he turns into. But the Ultimatrix can scan the DNA of other Pokemon and therefore allow Ben to transform into them.

If he were to do so, that could leave him vulnerable to capture by Pokeball. That said, just throwing one at him won't be enough--the trainer needs to weaken him in battle too, which Ben would likely suss out and either retreat or transform before it's too late to turn the tide in his favor.

Transformation-induced regeneration might be possible. And turning into different creatures every so often is bound to elicit surprise, maybe make Ben even more of a priority for trainers to catch because of the sheer breadth of forms he can take, and therefore powers he brings to the table.

From the ice-breathing moth called Big Chill, to the plant-fire hybrid named Swampfire, to the larger-than-life, humanoid tiger known as Rath, Ben probably has an answer for the various Pokemon that an ordinary trainer will likely send out. And if they employ Mega Evolution in an attempt to turn the tables, Ben can respond by going Ultimate.

Not until you brought it up; nice find, though. The striking similarities between Ben 10 and Pokemon characters make me wonder--even moreso than I have before--if the resemblance is more than mere coincidence. I'd go so far as to speculate that they've taken cues and inspiration from one another, albeit probably not obvious ones to the average TV-goer.

Since he doesn't tend to go for them immediately unless the situation seems dire enough, I wonder how trainers who Mega-Evolve their Pokemon to get an edge will react to Ben countering by going Ultimate. The sight of him slapping the Ultimatrix and four spikes appearing on it, before a green light consumes his body and leaves a much stronger, different-looking alien in its place that bellows "Ultimate [insert name here]!" should be a surprise, to put it mildly.

With regards to Ultimate Humungousaur especially, I wonder if any Mega Evolutions can withstand bombardment from his missile hands (which is used in the other clips I brought up here).

I suppose this makes for a triple post, but a certain elephant (or rather, To'kustar) in the room ought to be addressed. I wonder if the Pokemon world has an answer for Way Big, who's basically a colossal Ultraman expy that serves as one of the strongest aliens in Ben 10's arsenal.


And that all discounts Way Big's evolved form.
