This set includes 6-inch figures of Zartan, Ripper, Buzzer, and Torch, fully decked out for the Band of Vipers World Tour. Prepare for a stage invasion with over 29 accessories, including guitars, bass, keytar, and a drum set! Even the packaging replicates the Springfield Theater.

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

For fans who prefer a retro vibe, Hasbro and Super7 are collaborating on a Cold Slither Zartan ReAction+ figure. This 3.75-inch figure channels the classic A Real American Hero aesthetic, featuring O-ring construction, vintage packaging, and a UV-reactive glow-in-the-dark feature. It also includes microphone and guitar accessories.

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.

Hasbro's commitment to the musical theme extends beyond figures—they're releasing a Cold Slither album in collaboration with Reigning Phoenix Music! The album description:

"In 2025, Cold Slither, the iconic heavy metal band from G.I. Joe lore, unleash their highly anticipated debut album. Featuring the phenomenal self-titled anthem “Cold Slither,” the album delivers 10 electrifying tracks blending searing guitar riffs, pounding rhythms, and irresistibly catchy choruses."
