negasonic and yukio

One possible fanfiction could be about Negasonic Teenage Warhead and Yukio going on a secret mission together. They might face some challenges that test their friendship and powers. For example, they could be trapped in an abandoned building filled with strange mutants and have to use their combined abilities to escape.

A plotline could be that they discover a new mutant who has powers that are linked to both of theirs. They have to work together to help this mutant control their powers and also protect them from a group of anti - mutant extremists. This would force Negasonic and Yukio to communicate better and combine their unique skills.
