The G.I. Joe Classified: Dreadnoks Cold Slither - Band of Vipers set features 6-inch figures of Zartan, Ripper, Buzzer, and Torch, all styled for their Band of Vipers World Tour concert. Accompanying the figures are 29 accessories, including a variety of musical instruments such as a guitar, bass, keytar, and drum set. The packaging itself is a nod to the iconic Springfield Theater from the show.
This exclusive set will be available at San Diego Comic-Con, taking place from July 24-27, 2025. Following the event, a limited number of sets will be offered on the Hasbro Pulse website.
For fans who enjoy a more nostalgic touch, Hasbro has partnered with Super7 to introduce Cold Slither Zartan to the ReAction+ line. This 3.75-inch figure, reminiscent of the classic A Real American Hero toys, features O-Ring construction and vintage-style packaging. It glows in the dark under UV light and comes equipped 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 3 at 9:15am PT.

Hasbro is fully embracing the musical aspect of Cold Slither by releasing an actual album in collaboration with Reigning Phoenix Music. Here's the official description:
*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.*
