The Chosen Children first encountered Piccolomon when he used his Bit Bomb attack to defeat Kuwagamon. Disgusted on how the Chosen Children Digimon did not fight him, he decided to train the group in his hidden jungle lair in the desert under a magical veil that Etemon did not know of. Piccolomon speaks in a quick falsetto voice and always ends his sentences with 'pi'. Later on, Piccolomon returned to save the Chosen Children from the Dark Masters. He sacrificed himself so that the Chosen Children could get to Spiral Mountain.
