Cataclysm is a Predacon who viciously clawed his way up Shokaract’s chain of command to become one of his elite Heralds, with his eye on becoming the Herald Maximo, second only to Shokaract himself. A great enmity exists between him and Antagony, the current Hearald Maximo, and both have attempted to undermine and eliminate the other. Cataclysm is extremely intelligent and utterly ruthless.

I chose to go in a different direction and use a Beast Machines Night Slash Cheetor base, being that FoxKids already made one with the Transmetal body.
I did a full disassembly , paint, seal and reassembly, to prevent joint cracking. All gimmicks and transformation are still intact for play sake.
