RustTyranomon is a Cyborg Digimon whose name and design are derived from "Rust Tyranomon". It is the Mega of Tyrannomon, which has been living through the fierce, long-lasting battles since the Digital World's birth by digivolving alongside it. It has endured many years in harsh environments as MetalTyrannomon, and its whole cyborg body is rusting. Its tactics specialize in annihilation warfare, mowing down its enemies along with their base as one. RustTyranomon predates on Digimon, gorging on hundreds of thousands of Digimon within a short period without leaving any trace. As a Cyborg Digimon, it forces the opponent to yield in close combat with its top-class power and destructive force.

- Terror's Cluster: Extends the gun battery on its back forward and fires the large electromagnetic cannon.
- Rust Breath: Spews deep scarlet flames, the same color as its body, which have a rusting effect on that which is touched by its front.
