DexDorugoramon

DexDorugoramon is the wild Mega form of Dorumon, the corrupted form of Dorugoramon. It is known as Death-X- DORUgoramon in Japan. It is depicted as a huge dragon beast whose size dwarfs that of his pre-evolved state, DexDoruGreymon, and even the Royal Knights Omegamon and Alphamon, film Digital Monster X-Evolution.

Dexmon
Dexmon is a Ghost Digimon and a carrier of the X Antibody whose name and design are derived from "Death-X". Since it doesn't have its own DigiCore, this type of program cannot be classified as a Digimon, and although it appears solid, it has no actual substance. If it detects a DigiCore it will absorb it into its body and disintegrate it, then reassemble it in a perpetually repeating set of processes named "Process '0'" through "Process 'F'". Although it is a simple program, it is thought that defeating it is within the realm of impossibility. Unless there are DigiCores nearby, it will go into stasis, but as long as there are DigiCores it will not cease.
