Teenage Mutant Ninja Turtles Universe #25

Leonardo charges forward through flames, twin katana raised toward a massive, glowing-eyed armored visage looming above him, while ghostly figures — including what appears to be a snarling beast and a stone-faced warrior — loom in the smoky background of this striking Freddie E. Williams II cover. It's a powerful visual send-off for TMNT Universe #25, the final issue of IDW's expansive anthology series, with Ian Flynn writing and Nelson Dániel handling the full art duties on "Spirit Walk." If you've been following this corner of the Turtles' world, this issue looks like a fittingly dramatic conclusion.
