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 killer box set featuring Cobra villain Zartan and his Dreadnoks, transformed into the heavy metal band, Cold Slither.

This action figure set, titled "G.I. Joe Classified: Dreadnoks Cold Slither - Band of Vipers," is inspired by a classic G.I. Joe: A Real American Hero episode and will be a San Diego Comic-Con exclusive this summer. 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. The set boasts an impressive 29 accessories, including various musical instruments like a guitar, bass, keytar, and drum set. Even the packaging is designed to resemble the Springfield Theater.

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

For fans of classic G.I. Joe figures, Hasbro is collaborating with Super7 to release a Cold Slither Zartan figure in Super7's ReAction+ line. This 3.75-inch figure, reminiscent of the original A Real American Hero toys, features O-ring construction, vintage packaging, and glows in the dark under UV light. It also includes microphone and guitar accessories.

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

Hasbro is taking the musical theme even further with the release of an actual Cold Slither album in collaboration with Reigning Phoenix Music. The album description reads:

"In 2025, Cold Slither, the iconic heavy metal rock band from G.I. Joe lore, are releasing their highly anticipated debut album. Headlined by the phenomenal self-titled anthem “Cold Slither,” the album delivers 10 electrifying tracks that blend searing distorted guitar riffs, pounding rhythms, and irresistibly catchy, anthemic choruses."
