Meet Titanjaw

Titanjaw is the mechanical T. rex at the center of Dr. Silas Vex’s plans in Mason Rex and the Power Fossil. Built from black steel and bronze mechanisms, it carries a glowing Primal Core fragment inside its chest.

Powerful piston legs, an armored frame, and a heavy segmented tail make this machine a formidable threat in Red Rock Falls. Amber energy runs through its systems, linking ancient fossil power with Vex’s engineering.

A control cradle lets Vex pilot Titanjaw. For Mason Rex, facing this mechanical dinosaur means understanding how it works as well as finding the strength to stand against it.
