Tom Waltz and Kevin Eastman have been dragging more and more classic TMNT characters and elements into the new series in recent months. Issue #15 throws Leatherhead into the mix. Though the book hardly needs another villain at the moment, Leatherhead nonetheless enjoys a solid introduction into this new continuity.
The writers briefly establish Leatherhead's origin as another of Baxter Stockman's out-of-control experiments before shifting back to the present. The Turtles are currently searching for a new base of operations, which seems like another unnecessary addition considering how recently they moved into April's antique shop. In any case, issue #15 winds up offering a fun little blend of intrigue, horror, and levity. In the case of the latter quality, Splinter is given the opportunity to stop being so dour all the time and bond with Casey Jones. As far as horror goes, the creators offer up a cool sequence that sees Leatherhead stalk the Turtles in the shadows.
