Overview
The Malfunctioned Tek Rex is a powerful carnivore with a unique twist: it can be carried as cargo by larger creatures. This allows for strategic deployment in combat or transport scenarios where mobility is key. It is typically used by survivors who need a high-damage predator that can be airlifted into position.
It can be carried by Tusoteuthis, enabling surprise attacks or rapid relocation across difficult terrain.
