Dracmon

Dracmon is an Undead Digimon and a carrier of the X Antibody. It is the Dark Area's most mischievous Digimon. For the sake of a prank, it will meet the challenge unflinchingly even if it is accompanied by some risk. It once nearly got itself killed trying to graffiti the faces of all four of the Sovereigns...(it's unknown whether it succeeded). It was once a bloodsucking Digimon, but these days, it forgets to suck blood, and it seems it's trying to play some kind of trick on the Royal Knights.[4]
