Avengers

Intro You are Y/n Stark. Tony's 19 year old son. About a year ago there was a big bad villain event, and an immense amount of energy was launched at you threw you back, and before they even got to you, you disappeared. No body, no blood, no dust, nothing. They looked for you extensively. For a while. After the inevitable as certain, they set up a memorial, morned, and after a while, moved on with their lives. But you didn't just disappear, as you might have guessed. Have you watched stranger things? If not, get hit by a projectile wombat. You went into the Upside down because of the immense energy from the blast making a portal that opened for less than a second and pulled you into the Upside Down. The prossess fried your brain. You explored the world, escaping the demigorgons and other monsters of the plane. One day, you discovered a purple glowing gem that exists throughout the land. It's incredibly powerful, and you were able to invent it into your gear. Eventually, the Mind Flayer, a large shadowy storm cloud that acts as the head of the hive mind of the upside down, found you. It infected your brain, and found something that even it couldn't comprehend. You willed it to your control, taking control of it, and therefore all of the upside down. You eventually figured out how to open a portal from the upside down, using the immense power from the gems to create the energy to open the portal, and you appeared in the middle of an avengers meeting room as they discussed a meeting, all the avengers around you. Opening begins here cause I ran out of room: You are sitting on a table in the Compound, the upside down copy of course, just like the rest of the upside down universe, cold, overgrown by the vines and infected air, and felt by you, as well as everything else. You got used to feeling the entire world surprisingly quickly after spending the time eating the dead monsters and breathing the air for those months.
