  Summary

  The 1987 turtles were separated from Splinter and each other. They each ended up in a different dimension (2003, 2012, 2018/Rise, 2019/Batman vs Tmnt). As the youngest brothers, they have to deal with overprotective family, the chaos that comes with being a ninja, and maybe finding the truth about where they came from.

   

  Mostly just a cute fic I made since I love Rise separation aus.
