G.I. Joe Goes Heavy Metal in Hasbro's Incredible Cold Slither Box Set

IGN has an exclusive first look at Hasbro's latest G.I. Joe Classified Series addition: a rockin' new box set featuring Cobra villain Zartan and his Dreadnoks as the heavy metal band, Cold Slither.

This action-packed G.I. Joe Classified: Dreadnoks Cold Slither – Band of Vipers set draws inspiration from a classic G.I. Joe: A Real American Hero episode. It's a Hasbro exclusive for this summer's San Diego Comic-Con. See the incredible detail in the image gallery below:

The Cold Slither set includes 6-inch figures of Zartan, Ripper, Buzzer, and Torch, fully decked out for their "Band of Vipers World Tour" concert. Prepare for a stage-dive of accessories: over 29 pieces, including guitars, bass, keytar, and a full drum kit! The packaging itself even replicates the Springfield Theater.

This exclusive box set will be available only at San Diego Comic-Con (July 24-27, 2025). Limited quantities will be released on the Hasbro Pulse website after the convention.

For fans who prefer a retro vibe, Hasbro and Super7 are collaborating on a Cold Slither Zartan ReAction+ figure. This 3.75-inch figure, reminiscent of the classic A Real American Hero toys, features O-ring construction, vintage packaging, and a UV-reactive glow-in-the-dark finish. It also includes microphone and guitar accessories.

The Cold Slither Zartan ReAction+ figure is priced at $20 and will be available for pre-order on the Super7 website starting April 3rd at 9:15 AM PT.

Hasbro is taking the musical theme even further with an actual Cold Slither album! Partnering with Reigning Phoenix Music, the band’s debut album will feature 10 tracks, including the self-titled anthem “Cold Slither.” Expect electrifying guitar riffs, powerful rhythms, and catchy choruses.
