The Old Bells of Trolberg (Omnitrix AU) by Ironstone8247
Fandoms: Hilda (Cartoon), Hilda Series - Luke Pearson & Stephen Davies, Ben 10 Series

Summary
From what Hilda had heard, sentries along the wall had been pretty relaxed in past years, because it wasn’t really a need to be leery with troll incidents growing rarer each year. But ever since the forest fire she caused after getting the watch, she had been worried that the guards may suddenly tighten their hold on the wall, especially with Ahlberg in charge.
Breaking rules wasn’t enjoyable in itself, but what else was she supposed to do? She needed to get a hold on this situation, and it would be nice if she didn’t have to do it alone.
Now that David and Frida know about the watch, Hilda wonders about what her next steps should be. Breaking rules and hiding things weren't her most favorite things, but with her new powers and a plot from Safety Patrol afoot, she might not have much of a choice
(You don't have to know Ben 10 to enjoy this; just Hilda)

Summary
As you know there are a lot of fan made Omnitrixies these days centered around either girls: the Chaquetrix and it's 10 million takes including the Genetrix, or violence: the Carnitrix or Waritrix or both: the Charnitrix.
But what if there was a watch in the Omniverse with both and Ben still transformed?
You see, in most universes, Azmuth, the first thinker, creates the Omnitrix, the Noah's ark of the universe, a watch like device capable of scanning the DNA of any species and then turn its user into any one of those species. Ben Tennyson's fate intertwines with Omnitrix, usually by bonding with it and use its capabilities to become the universe's greatest hero or being one of the greatest ally of the one that does.
This is not that universe at all.
In this universe, Azmuth creates the Galatrix.

Summary
Inspired by the Absolute Ben 10 fan comics by DuckSenile, and the original Marvel Ultimate comics, my take on the Ben 10 series if it got the original Marvel Ultimate comics treatment.
“It started when an alien device did what it did. It wrapped itself upon his hand with secrets that it hid. Now he’s got superpowers, he’s no ordinary kid. He’s Ben 10.”
During summer break, 13 year old cousins Ben and Gwen Tennyson, go with their Grandpa Max on a summerlong roadtrip across the country. During a night out on camping, Ben accidentally comes across a mysterious meteorite that contained a device which then leapt out and attached itself permanently to his hand. Armed with this unknown alien device, Ben must now unlock its secrets and learn how to control it before forces from beyond and on Earth go after him and the device.
