Originally a military-grade combat dinosaur, this Daspletosaurus was stolen and radically modified by Nero's underground tech specialists. They integrated experimental weapon systems far beyond legal limits, creating a walking artillery platform that became one of Nero's most feared enforcers.

The Doomcannon Daspletosaurus features multiple illegal weapon systems, including a shoulder-mounted plasma cannon array and neural-linked targeting systems. Its enhanced musculature and reinforced skeletal structure allow it to handle the massive recoil from its integrated weapons, while experimental power cores provide the energy for its devastating attacks.

Serves as Nero's primary enforcer and living weapon, demonstrating the Marauders' technological superiority through displays of overwhelming firepower. Its mere presence often forces compliance from potential rivals.
