Chapter 1

When Dean, Sam and Cas, Sherlock and Watson, and the Doctor try to defeat the Cybermen. Sorry if there are feels.

The doctor found a way to enter fictional realities and is really excited to take his new friends on a trip: Sherlock and Watson. They are on a planet until the Doctor smells something fishy. He decides that he needs more people who are trained at hunting. The Winchesters.
No spoilers, but they end up trying to defeat cybermen. The Doctor feels bad that he brought the Winchesters for nothing, but they honestly have fun, that is, until something goes really wrong.
