I was at an old Nazi concentration camp turned into an amusement park when cyborg aliens invaded. Big boxy ships landed all over and started setting up massive industrial machinery everywhere; huge digging robots were already tunnelling straight down.
The humans had taken refuge in the food court, but nobody had actually been hurt or killed at that point. Eventually the aliens beamed down a representative to talk to us, a clone of James Earl Jones wearing a toga and a thin wreath of woven reed. Most people were freaking out and/or terrified, but I was staying pretty calm so I was chosen to speak for everyone there.
The faux JEJ explained that the aliens didn't have hostile intentions towards us, they were only going to irrevocably alter our planet's biosphere in a fashion that would only superficially alter our way of life. Everyone was going to get tons of cybernetic implants and genetic modificiations, but wouldn't be mind-controlled or brainwashed. They weren't here to wipe out humanity, only to force a sort of scientific evolution, because even though they weren't threatened by anything in particular at the time, they wanted to spread their technology as much as they could so it would survive their own potential extinction.
As an example of how things would be "the same, but better", he showed me a condiment rat, a weird, bloated little rodent. He shoved the thing in a big machine that sprouted various articulated blades, and proceeded to cut the critter apart in a few seconds, shredding and discarding most of the bones and meat but preserving three elongated bladders, one red, one yellow, and one green. Then he explained to me how this genetic experiment, while gruesome in appearance, much simplified and streamlined the production of ketchup, mustard and relish, and that in a few more generations the animal's meat could naturally form into hot-dog weiners. The aliens themselves didn't actually need to eat anymore, but they had decided that food was an important part of human culture and needed to be preserved.
"So, how do you feel about our little invasion now?"
"...I... uh... I'm gonna have to think about it."
Fortunately I woke up before I had the time to.
