Ben is driving a while after the final battle in Ultimate Alien and ends up in a portal to another world.
Ben doesn't get the new Omnitrix due to Azimuth not finishing it yet.
Ben now is on a new mission to help this world where he was killed by the...
I was asked so here's the AnimeEagleScout staple Tech Breakdown.
Ben's Brain and context
This story takes place before Omniverse after the last episode of Ultimate Alien. The time gap between the two is
Between the two be has went back into Plumber training and advanced to the highest rank available for his age Alpha Officer. Magisters requires being 18 to start the training and 21 to be a fully realized one.
For details on the rank it's basically Hero Work with a paycheck and structuring in missions. Ben is basically a E4 if you want a comparison in the military.
Ben's goals are to help Terra [Earth but his Plumber Badge translator basically calls it Dirt Wad so Plumbers say Terra.] Rise to join the Prime Circle.
The Prime Circle is a group of planet's that started before Highbreed went blood purity and Galvan's were only a few hundred years ahead of current humanity not thousands.
Primes includes the world's of the whole Omnitrix original Playlist along with the Highbreed, Vilgaxia, the Anur System planets. A few more exist but the list isn't exactly written fully.
A species joins the Prime Circle once they get the vote of existing circle members. Ben treated this as a "Celestial Phoenix" before his 'change in thinking' and now has a goal how it can be done and in his lifetime.
Duel Neural Adaption:
Ben's brain has a tendency of feeding the Omnitrix. "It knows me more then me.". Ben's mind has been treating the Omnitrix as the 'Main Memory' essentially so his 'character development' gets reset when an Omnitrix gets removed or reset. Like in War of World or Master Control in the original series.
His memory's are in his head but his brain chemistry gets reset to the day he put it on.
This results in him being, Whiny, Unfocused, Prone to dumb decisions (like breaking into the Omnitrix in AF) slight memory loss.
Ben has had the Ultimatrix on long enough for his development to 'grow back' to the point he's at 'Pre War of the World's Ben.' Before he enters this universe.
Intelligence:
Ben's brain has been effected by the Ultimatrix "Bleed" Feature.
When Ben goes an alien the Omnitrix is supposed to prevent Neural Shifts like this:

[When skurd got off him Kyber's brain was regressed by the Nemetrix. That is a Neural Shift.]
Ben would turn into that thing without a proper compensation and prevention of "Bleeding" that creature into Ben's normal brain.
Ben had got the Master Command Code from Ultimate Greymatter loading his transformation to Gwen's Omnitrix. [Ben's Ultimate Greymatter has a Galvanic Mechamorph for his arms and tech control like Cooper instead of being a Modoc reference.]
