Teenage Mutant Ninja Turtles #25

In "The River Part 2: River Hymn," the remaining Teenage Mutant Ninja Turtles—Leonardo, Donatello, and Michelangelo—join forces with Casey Jones and the Native American elder Abanak to protect a sacred river from a corrupt politician and his complicit police officer. Written and illustrated by Rick Veitch, this 1989 issue continues the environmental and cultural stakes of the series with a grounded, emotionally resonant story, its cover by Veitch capturing the quiet urgency of the moment.
