Hasbro’s Transformers x Monster Jam crossover has moved from teaser to full spec sheet. On July 16 the product description for the line’s flagship figure, the Leader Class Grave Digger Grim, went public, detailing the premium truck that anchors the collaboration.
Grave Digger Grim stands 9.25 inches (23.5 cm) in robot mode and converts between robot and a Grave Digger-inspired monster truck in 24 steps. The figure ships with a flag accessory, two exhaust pipes that combine into a scythe, and three blast effects.
The Leader Class release tops a lineup Hasbro first showed on June 5, when it revealed two deluxe-scale trucks: El Toro Loco Furioso and Megalodon Big Tooth. Both deluxe figures wear Autobot insignia on their shoulders and carry Monster Jam branding across the chest in robot mode.
The Monster Jam team-up continues a run of licensed Transformers crossovers in 2026. It follows the Transformers x Scooby-Doo Mysterious Prime and Automutt set, the Hot Wheels collaboration, and the Jem and the Holograms Blaster redeco headed to San Diego Comic-Con.
Pricing and a firm release date for Grave Digger Grim have not been announced. We will update this page when Hasbro opens preorders.
