Digimon Frontier
After Lucemon began his cruel rule of the Digital World they rose and defeated him sealing him into the Dark Area. After this they were separated into two spirits each (likely because they were injured in the battle). The Chosen Children later inherited these spirits to take their place.

Revival of the Ancient Digimon
Ancient Greymon and Ancient Garurumon brought down Ornismon. Their spirits and force were temporarily revived in order to defeat their enemy due to the legend of the island.
