The Cold Slither set includes 6-inch figures of Zartan, Ripper, Buzzer, and Torch, fully equipped for their "Band of Vipers World Tour" concert. The set boasts 29 accessories, including a guitar, bass, keytar, and drum set. Even the packaging replicates the Springfield Theater.

This box set will be available exclusively at San Diego Comic-Con (July 24-27, 2025). Limited quantities will be available 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, featuring O-ring construction and vintage packaging, glows in the dark under UV light and includes a microphone and guitar.

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 further embracing the musical theme with the release of an actual Cold Slither album in collaboration with Reigning Phoenix Music. The album features ten 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."
