Also, his appearance might change drastically, which could affect how he's perceived by others in the TMNT world. Another consequence could be that he develops new mental or emotional states due to the double mutation, like increased aggression or a new sense of purpose.
He might gain new physical abilities, like enhanced strength or speed.

It could also be a form of creative exploration that goes way off the beaten path.

Well, his brothers would probably go on a wild rescue mission. They'd search every nook and cranny of the city. Maybe they'd get some help from April and Casey too.

They'd be desperate to get Mikey back to his normal, energetic self.
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 this kind of fanfiction, the creators usually play with the characters' original traits. Karai, with her ninja skills and her own motives, could either be an ally or an adversary to Dark Mikey. For example, they might be forced to team up against a common enemy, and during that process, they start to understand each other better. It's all about exploring the uncharted territories of their personalities and the possible dynamics between them.
