Teenage Mutant Ninja Turtles #21

Against a smoldering orange sky, all four Turtles stand their ground atop a rooftop ledge while a fearsome, spiky-armored insectoid warrior — sword raised high — looms over them in a dynamic, mid-combat pose. The contrast between the Turtles' guarded stances and the creature's ferocious energy makes this Image-era issue feel genuinely intense and a little unpredictable. Fans of the grittier, darker take on the TMNT mythology will find this cover a compelling snapshot of the series at its most visceral.
