This cosmic race was truly something else. In all my travels I have seen and encountered many things but never have I ever encountered such a high-level civilization, if I were to go by the Kardashev scale, they would be put around level 5-6.
When I first arrived at their civilization, I decided to squeeze them dry until they had no more technology to give me, destroying them was such a waste of potential.
My arrival was not undetected but before they could react, a Black Hole appeared in their dimension, or at least it looked like a Black Hole, in truth, it was something different but way more terrifying.
While this Black Hole also had an enormous pull, its influence went beyond just the material world. What looked like a Black Hole was actually an opening to a void in which I was planning to imprison their entire civilization.
I was basically doing the Brainiac collection on a much larger scale, he collected cities while I collected entire multiversal and higher dimensional civilizations.
After a full year of playing tug and war over their time-space continuum, I finally captured them in a snow globe. While it might look tiny, the inside was many times more spacious than a multiverse, the only problem being that there was neither time nor space in the void and they had no materials to further create stuff.
I was going to have to deal with that problem soon, right after I changed the memories of their entire species, I have no doubt that if they were given the resources they would use all of It to break free, which I obviously couldn't allow. If they don't know they are captured then they won't want to break free.
On a side note, I have rarely spent so much energy on one task, they had technology that gave them major control over their regional space-time continuum and even had a defense against it. At some point during the capture process, I was interrupted by a group of children with a hero complex and a professor.
I never wanted to kill Paradox because killing someone with so much power over time can be complicated and lead to consequences but I was too busy to entertain them and had to focus my attention on more important things. After a massive beam of destruction, time, space, death, and many more elements hit the group, most of them ceased to exist.
And I mean that literally, I didn't kill them but straight out erased them from existence. Hitting one Ben would have been enough to erase all Ben Tennyson's from existence but I hit an entire group. The moment Paradox, who failed to escape as my attack transcended time, was erased, I felt the entire reality shake.
I had just erased someone who messed with time frequently and due to him being erased from the past, present, and future, all his actions disappeared with him. Reality struggled to repair itself as I had just taken on of its crucial pieces. He was gone but the consequences of his actions were still there and that wasn't possible since he never even existed.
The only Ben who partly survived was Ben 10k. After his arrival, he immediately transformed into his strongest Alien, Atomic-X, a fusion of his two strongest Aliens, Alien X and Atomix. While the mix allowed him to wield part of Alien X's power, it had a price for bypassing the other two minds. While the body of Atomic-X remained unharmed from my attack, his mind and soul still got erased, leaving an empty shell behind.
He refused and feared to be part of something bigger than him and paid the price for it. If he just turned into regular Alien X, I would not have been able to erase his mind and soul without some effort that I could not spare at that moment.
It was time to go back to the Tower. Although they didn't transcendent time like I did, they should at least have felt the change in time flow.
There were still some small things I wanted to do before going to DC, like changing my technological worker ant's minds and playing ROB. Maybe someone will get unlucky and reincarnate in DC.
