TMNT Saturday Morning Adventures #40 — Mondo and Metalhead take the spotlight in Dan Schoening’s latest

Metalhead sees a threat nobody else can, and it’s up to Mondo Gecko to rally the Turtles. Dan Schoening and Erik Burnham deliver a sewer-level adventure that keeps the Saturday Morning vibe fresh and fun.

If you’ve been riding the wave of TMNT Saturday Morning Adventures, you know how effortlessly Erik Burnham and Dan Schoening capture that specific flavor of 80s cartoon joy. Issue #40 isn’t just another installment; it’s a love letter to the side characters who usually hang in the background, giving them the spotlight they deserve.

Down in the depths of the New York sewers, Mondo Gecko and Metalhead have carved out a pretty sweet existence. Their Lair is a sanctuary of video games and good times, a place where the chaos of the surface world feels very far away. But that peace is about to get interrupted in the most Metalhead way possible.

The trouble starts when Metalhead begins glitching out, seeing an enemy that only he can perceive. It’s a situation too big for Mondo to tackle solo, which means it’s time to call in the big guns. When your only option is to round up four ninja turtles and a wise rat sensei, you know the stakes are high, even if the tone remains delightfully lighthearted.

This one is a pure joy to read. Dan Schoening’s art is as crisp and expressive as ever, perfectly balancing the retro aesthetic with modern comedic timing. Watching Metalhead’s mechanical frustration and Mondo’s enthusiastic but panicked energy creates a dynamic that feels both new and deeply familiar to long-time fans.

While you’re grabbing this one, keep an eye out for the companion reads that have been flying off the shelves. The recent runs have been so strong that picking up a mid-series issue feels like walking into the middle of a conversation you instantly understand. Trust me on this one—it’s a great place to jump in.
