Isaac Escorza

Isaac Escorza is the Mexican comic artist who, as one half of the Escorza Brothers alongside his identical twin Esau Escorza, draws the biggest Teenage Mutant Ninja Turtles comics of the modern era—including the record-breaking Teenage Mutant Ninja Turtles: The Last Ronin. From the sci-fi, fantasy, and horror pages of Heavy Metal magazine to the grim, rain-lashed future New York of IDW’s Ronin-verse, his painterly, European-inflected action art has made the twins the definitive visual architects of the Turtles’ darkest era. Perfect for fans of Heavy Metal’s fantasy bombast, Frank Frazetta’s brooding epics, and TMNT’s gritty adult reinvention.

From Heavy Metal to Taarna

Born and based in Mexico City, Isaac and his brother Esau—identical twins who work so tightly that they’re billed simply as “the Escorza Brothers”—cut their teeth in genre comics as illustrators for Heavy Metal, the storied anthology that Kevin Eastman himself once helmed. Their most notable Heavy Metal work was Taarna, the 2018–2019 miniseries reviving the iconic heroine of the 1981 animated film, written by Alex De Campi and illustrated by Isaac and Esau. The lush, darkly rendered style they honed there—equal parts Frank Frazetta and European bande dessinée—became the signature look they’d later bring to the Turtles.

The Last Ronin Breakout

Their breakout came in 2020, when COVID-19 derailed the original art lineup on The Last Ronin. It was Eastman’s wife Courtney who remembered that Kevin had worked with the Escorzas before—and the brothers jumped onto the book, becoming its primary artists alongside Ben Bishop and Eastman. The five-issue saga of the last surviving Turtle became a phenomenon: IDW’s highest-printed single issue ever, a New York Times bestselling collection, and the launch of a “Ronin-verse” spanning sequels, a video game, and a planned live-action film. Working through a language barrier—English isn’t the twins’ first language, and they communicated via translator at their NYCC panels—Eastman kept his layouts clear and slang-free. Isaac returned the respect. “Kevin has helped with layouts and has been respectful about the art and the final result,” he told Screen Rant. “He gives us a chance to do what we want the way we think it should go without stepping on it.”

The Ronin-verse and Beyond

The twins carried that momentum straight into the rest of the franchise, reuniting with Eastman, Waltz, and Bishop for The Last Ronin II—Re-Evolution (drawing the present-day sections while Bishop handled flashbacks), The Last Ronin—Lost Years, the 2026 one-shot Training Day, and IDW’s current TMNT: Battle Nexus. Their covers are everywhere too: the pair contributed more than 100 pieces across the Last Ronin and Re-Evolution cover collections, alongside work on Gatchaman at Mad Cave Studios, Star Trek at IDW, Frank Frazetta’s Death Dealer at Opus Comics, TMNT Saturday Morning Adventures II, and even cards for Magic: The Gathering.
