Teenage Mutant Ninja Turtles: Journeys #16

Leonardo and Karai face a mysterious warrior who humbles Leonardo in a manner he has not experienced before. Donatello and his exploratory team, having been shrunk, encounter others from Earth who share their predicament. Elsewhere, a mega-mutated Raphael is proving difficult for anyone to stop. The issue keeps three separate threads running and leaves the brothers further apart than at any previous point in the series.
