Imperialdramon PDM is a Legendary Digimon and the secret Dragon mode to the founder of the Royal Knights, Imperialdramon Paladin Mode. Whenever Paladin Mode faces an issue it cannot face under normal conditions, it becomes it's Dragon Mode which is said to be more powerful than his regular mode. Those who see this divine dragon dare not oppose it's mighty power, for fear they shall be instantly destroyed before they can even react.
Digimon World: Bronze and Cobalt Versions
PDM can be obtained by first facing it as a secret boss, after which Paladin Mode can mode change into PDM. It's stats are identical to Paladin Mode, but it's signature trait is the same as Dragon Mode's, making it more powerful than a normal Super Ultimate. PDM cannot be used in random online battles due to it's power rivaling that of Gaiamon, but unlike Gaiamon it CAN be used alongside other Digimon in the party since PDM has only a size rank of 2 where Gaiamon has a size rank of 10, which prevents any other Digimon from being able to be in the Party.
