A Digi Xros of MetalGreymon and Deckerdramon
The "Assault-strike Mode" which added Deckerdramon's offsensive and assault abilities to Metal Greymon's power. Its comprehensive combat strength is equivalent to that of a battalion composed of 324 combat-model Digimon, and it can use multiple Special Moves against multiple opponents. Even if you are able to take DeckerGreymon down, the immense energy that is released all at once from its body becomes a shock wave that scorches the earth for 10 km in every direction.
