Plesiomon X is a Plesiosaur Digimon and carrier of the X Antibody. According to the latest research analyzed from its high-pitched, crystal-clear cry, it has become clear that most of Plesiomon's configuration data is surprisingly "poetry" data. It has taken on a beautiful figure that feels so noble and elegant that some researchers have said that it is related to the legend of a tragic bard who was unable to see themselves as a dragon and sang about their deepening sorrow, and it very rarely makes an appearance. Furthermore, it is said that Plesiomon has another form within this fantasy, but this is unclear.[1]


  • Sorrow Blue: Sings with a high-pitched, crystal-clear voice, wrapping the listener in sorrow and making them lose their fighting spirit.
  • Fantasy Mist: Wraps the listener in a fantasy with the melodies it plays using its long barbels.
  • Shaking Pulse: Attacks with a high frequency sound wave unleashed at maximum intensity.


Plesiomon X is an altered version of Plesiomon.
