Razenexus Titan is actually a Pyrus and Darkus Mechtogan Hybrid created by Igor Kazami, Valentin Kazami's father. It was created using the DNA and genes of a Pyrus Venexus Titan and a Darkus Razen Titan.
Razenexus Titan is a huge hulking Mechtogan capable of using Pyrus-based attacks and Darkus-based attacks. It has two main heads (a Razen Titan's main head and Venexus Titan's head) and two "secondary heads" (the other two Razen Titan "heads"). It can send earth-shattering waves of fire and darkness at its enemies. It has razor-sharp claws and power cannons prodding from its arms.
