What was another day in Teufort turns into a problem. Pyro was going to have another day of ceasefire to do whatever he wanted, but when he goes to check on his friend, the Engineer, things turn south. In another universe, there were the Avengers. Everything was settling down well from Loki and the Chitauri... when suddenly, they are now faced with something they didn't expect.

So, I've read the "Avegers meet TF2 challenged!" by barber477 andI would like to say one thing: CHALLENGE ACCEPTED! But I would like to add my own little...twist.

This is a challenge/call-out to authors from all over Fanfiction to make an epic crossover that should have happened a long time ago, and that I'm surprised hasn't already been made. Avengers meet the characters of Team Fortress 2! Just imagine if the classes from TF2 did something such as fighting with the Avengers in New York? This crossover must happen!
