The Cold Slither set includes 6-inch figures of Zartan, Ripper, Buzzer, and Torch, ready for their "Band of Vipers World Tour" concert. With over 29 accessories, including guitars, bass, keytar, and a drum set, this set is packed with playability. 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 collaborating with Super7 to release a Cold Slither Zartan ReAction+ figure. This 3.75-inch figure, reminiscent of the original A Real American Hero toys, features O-ring construction, vintage packaging, and even glows in the dark under UV light! It includes a microphone and guitar.

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.

And the musical theme continues! Hasbro is partnering with Reigning Phoenix Music to release an actual Cold Slither album. 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."
