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 a whopping 29 accessories, including guitars, bass, keytar, and a 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, Hasbro is also 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 comes with 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.

And that's not all! Hasbro is taking the musical theme to the next level by releasing an actual Cold Slither album in collaboration with Reigning Phoenix Music. The album features 10 tracks, described as: "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."
