Yo Joe! If you’re a fan of G.I. JOE: A Real American Hero, then hopefully you didn’t miss the excitement at San Diego Comic-Con 2025.

Hasbro announced that Cold Slither, the fictional Cobra Command band from the iconic animated series, would step on stage for a first-of-its-kind live performance at the Brick by Brick venue in San Diego! Cold Slither was brought to the stage by a supergroup of real-life heavy metal veterans and G.I. JOE fans – Gus Rios (Gruesome, Left to Die) as Zartan, Ross Sewage (Ghoul, Impaled, Exhumed) as Torch, Matt Harvey (Exhumed, Gruesome) as Ripper, and Andy Selway (KDFM) as Buzzer.

To celebrate and commemorate this epic concert, Hasbro also teamed up with Reigning Phoenix Music, Super7, and Sideshow to produce limited-edition merchandise. For those who didn’t attend SDCC, Sideshow hosted a giveaway for a chance to score official event swag. We’ve got your guide to all the rockin’ reptile action from the now-closed contest below.

Cold Slither Official Merch

Cold Slither concert attendees were also able to purchase limited-edition gear including exclusive T-shirts, LPs, CDs, collectible pin sets, and more.

Who doesn’t love a limited-edition gig poster? Artist Luke Preece worked his heavy metal magic to create a unique poster design exclusively for this one-night-only event! A fellow ’80s comic book fan, Preece is renowned for his posters, band merch, and creative collaborations with powerhouse rockers like Metallica, Pantera, Slash, Judas Priest, Slipknot, Ozzy Osbourne, and Mötley Crüe.

Grab the Poster at the Show!

Each poster in the limited production run of 100 pieces was screen printed on rainbow holofoil paper by Monolith Press lead production artist Ross Sewage (stepping on stage as Torch during the performance). The print features the band’s serpentine logo accompanied by a cobra, skull, and crossed knives emblem, as well as the live event’s details. This Cold Slither poster was available exclusively at the live show, with any remaining posters sold at Reigning Phoenix Music at SDCC (Booth #4029).

Online Exclusive Poster at Sideshow.com

For fans who couldn’t physically attend the show but still wanted to immortalize the auditory onslaught, the Sideshow Exclusive Cold Slither (Swampfire Variant) Screenprint was ultra-limited to an edition size of only 50 pieces. It launched for pre-order at Sideshow.com on July 24, 2025. This alternate colorway was inspired by the 1986 Swampfire Dreadnok vehicle toy.

Cold Slither Album Drop

On Friday, July 25, Cold Slither’s debut album officially dropped. Featuring 11 tracks of Dreadnok-fueled chaos, the album includes a newly remastered version of the original TV track, as well as all-new music by this heavy metal supergroup.

SDCC attendees were able to hunt down two unique collector’s edition vinyl records: the Zartan Chameleon Blue Variant at Hasbro (Booth #3213), and Blood Moon Red Variant at the Reigning Phoenix Music (Booth #4029)!

Dreadnoks Action Figures

Super7 also released a G.I. JOE Classified Series No. 163 Dreadnoks Cold Slither: Band of Vipers Commemorative Action Figure set. This collection of 6-inch-scale figures featured Zartan, Ripper, Buzzer, and Torch — each equipped with their signature instrument and a wealth of additional accessories.

The set was available via Hasbro (Booth #3213), at SDCC, and ultra-limited quantities were also available via Hasbropulse.com.

And More!

Fans unable to attend SDCC or the concert event could also pre-order themed apparel, the CD album, and the Reigning Phoenix Music Dreadnok Attack Orange Gray Vinyl Variant.
