{The 2018 turtles meet their adult counterparts from the 2012 universe.} Krang Sub-Prime is up to no good and two universes must come together to fight him off. They must tread carefully as one of their own is in danger. How will they approach this threat to their lives and to the ones they love? Internal conflict and self-doubt play their part, but they will prevail and succeed. Because they always have. (Cover art is not mine)
