Note: this story came from an idea I got after reading the story Prisoner by Paddehfeets. You should check out their story, because it's really good. The main point of this is that this is an original story. Enjoy, and please leave a review; this is my first time posting work and all criticism is appreciated.
The pain had been unbearable since day one for Loki. He knew that when he had failed, that he would come for Loki. Sure enough, no less than a week had gone by in the Asgard cells before Thanos had magically transported him to the planet where the rest of the Chitauri resided. At first, it had been mental torture. Breaking into Loki's mind and making his worst nightmares become a reality. After that, they had moved to more physical things. That had lasted for three more years. Three years of suffering, Loki had been put through, and still, they continued.
He had, at first, believed that maybe they would get tired of him. After all, you could only torture someone for so long before it got boring. He had thought that for the first three years, which is what kept him going. He kept his hopes up until the second year came to an end. Then, he gave up. He stopped resisting the urge to scream as blood flowed out of this body. He stopped hoping that one day, someone would come and rescue him. Instead, he hid in the back of his mind, what had become a shell of his former self, and waited for death to befall on him.
Unfortunately, the day of his death didn't arrive. He continued to suffer for another year, till the day of deliverance had arrived. Thanos approached Loki, who was curled up on the ground, his knees pushed into his chest and chained to a rock. "My warriors have become tired of torturing you, little one. So, I have decided that I am returning you to the mortal world. They will do with you what they wish, maybe providing as more entertainment for us. But, remember this fallen one; we will return for you one day. And your world will fall, once again, into nothing."
With the final words of warning, Thanos sent Loki away, in a stream of darkness. Loki closes his eyes and lets the darkness engulf him. He feels the whooshing of wind around him and finally grunts as he hits the ground of a new world. He manages to squint his eyes enough to see the old familiarity of tall buildings off in the distance. Much more closer to him is greenery. Many trees surrounding walkways through the mini forest in the suburban area. No one seems to be out, and the darkness around him besides the light glowing of a moon straight above him tells him that it's nearly the middle of the night.
Suddenly, he hears fast-falling footsteps behind him. Then, comes the worried voice of Steve Rogers himself, "are you alright? Do you need any help-" before he stands over Loki and realizes who is actually in front of him. Loki hears him gasp and being talking to another invisible person. The last thing Loki hears is the words of Steve Rogers before drifting off into unconsciousness, "Umm… we may have a problem."
