Or perhaps there are other mutants in the sewers who sense Mikey's new power and come to either befriend or challenge him. These new characters would add more complexity and excitement to the story of Mikey's mutation.
April and Casey might also be part of this fanfiction. April could use her reporting skills to try and figure out what's going on with Mikey's mutation, and Casey would be ready to fight any new threats that come along because of Mikey's changed state. Also, Splinter, as their sensei, would be guiding them all through this difficult time, providing wisdom and training to help Mikey control his new powers if he has any.
He might gain new physical abilities, like enhanced strength or speed.

For example, they might be searching for the missing baby turtles, or they could be the ones who teach Mikey and Donnie important lessons when they finally reunite.
It could also be a form of creative exploration that goes way off the beaten path. Maybe the author wants to explore the idea of how the TMNT world would react if such an impossible biological event were to occur.

Well, first, you should check the major fanfiction platforms. AO3 is known for having a wide variety of fanfictions, so it's a good place to start. Enter the title in the search box carefully. FanFiction.net is also a possibility. Sometimes, smaller, more niche TMNT - focused fanfiction communities might also have it, but those can be harder to find. You might need to do some more in - depth searching on TMNT fan forums to see if anyone has a link or knows where to find it.
In a fanfiction, Mikey might get hurt during a mission to infiltrate a Kraang base. He could be detected by security systems and get zapped by some sort of electric defense mechanism.

They'd be desperate to get Mikey back to his normal, energetic self.
