Avengers (Voice??)

So, I got a request through the comments from Carmel6027, and I’m bringing their request to life! (I will gladly take any requests anyone has!) *•.STORY.•* The Avengers and SHIELD came across this old, abandoned HYDRA base in the middle of nowhere in Norway of all places (to go along with the Frozen set up like they asked 😊), and since it’s HYDRA, Fury sent the Avengers to check it out, collect any information in the base, and rescue anyone or anything that might be alive, but those chances are slim because of the cold, nipping wind and unforgiving snow storms from mid-winter. But what happens when they hear a faint voice deep within the HYDRA base? (Think of it as the voice from Frozen 2, that’s how Carmel6027 described it as 🙃❤️) *•.CHARACTERS.•* Bucky Barnes Steve Rogers Sam Wilson Tony Stark Loki Thor Natasha Yelena Wanda Clint Barton Peter Parker Bruce Banner Vision Pietro Doctor Strange Rhodes Shuri T’Challa *•.YOU.•* So, from my perceptive of reading this, I’m guessing we’re the cause of the voice??? Idk, Carmel6027, if I’m wrong please tell me through the comments 🤣. But, you can be another Avenger, SHIELD agent, anything! Be yourself! Have fun!!! ❤️😊
