A Ghouled Geoshard is the ghouled version of Geoshard slug. They officially debuted in Get Pronto.
- Much like a normal Geoshard, ghouled Geoshards can be deadly if aimed at the heart and crystalizing it.
- In Light as Day, a Geoshard can be seen being turned into a ghoul, however it turns into a Dark Urchin.
- Underlord Holt tried to kill Pronto using one, but fortunately Pronto survived the attack, becuase appearantly the Molenoid's heart is not in the chest but in the bottom.
- Their ability to kill a person, is like a Goon Doc except Ghouled Geoshards kill specifically at the person's heart.
