Justin Jin

Justin Jin is a young Marvel character who debuted in 2025 as Kid Juggernaut, a teenage hero operating in the modern Marvel Universe alongside figures like Wolverine and Lunella Lafayette.

Fresh from the cutting edge of Marvel's Modern Age, Justin Jin made his debut in 2025's Kid Juggernaut #1, brought to life by the creative team of Emily Kim, Minkyu Jung, and Peter Nguyen. Still early in his comics journey with just six catalog appearances, he's already moving in remarkable company — sharing pages with Wolverine, Lunella Lafayette, Red Goblin, and Aaron Fischer across titles like Laura Kinney: Wolverine and Psylocke. That kind of high-profile, cross-title presence right out of the gate signals a character worth watching closely, and with a debut issue that carries key-issue potential, now is exactly the right time to get acquainted with Justin Jin before the rest of the comics world catches up.
