[Ben 10] Ultimate / Evolved humans

Hi. In order to answer, I don't think you need to actually know about the show, I'll try to tell you enough.
So the show is about a device called the Omnitrix. What it does, is altering the user's DNA to transform them into different alien species. There is a copy of this thing, called the Ultimatrix. It's almost like the original expect it had something called the evolutionary function, which is what you need to know about. From Wikipedia:

The Ultimatrix had the ability to evolve aliens into their Ultimate Form, granting them new powers and new abilities that are more powerful. This was activated by pressing the Ultimatrix symbol as an alien, causing four gray spikes to grow.
The evolution feature worked by placing the selected species in a simulation, right down to the DNA, for an extended period of time, about a million years or so, in what is described as a "worst case scenario"; the actual DNA is then simply modified to match the new DNA. This survival of the fittest routine explains why the evolutions are more combat-centered than their normal forms.

If you want to have a better understanding of this, search "ultimate forms" in the Ben 10 wiki, and you will see the differences between the regular and ultimate aliens.

Let's get to the point. I wanted to know what would an evolved human be like if he was put into these stuff? (There are actually evolved humans in the show, but it simply says that they are slightly smarter than regular humans. Not satisfying. Also, sorry, my first time here.)

Iirc, it worked by simulating a long period of war to force the species to evolve traits that make them better fighters or more durable. For humans that might result in them being a bit more durable, perhaps even a little more resistant to radiation, but that would be about it.
