Raremon was a digimon that had invaded a pond nearby Devimon's fortress in the Forest of Illusion on the continent of Ainalani. While not evil, so to speak, this digimon was most definitely not in a healthy frame of mind, and lashed out violently when Jim and Gilamon approached the pond he had made his home. After a brief struggle, Raremon grabbed Gilamon and stuffed him into his mouth, intending to swallow him whole. At this point, the rest of the Chosen Ones arrived and worked together to not only free Gilamon but also to delete the Raremon.
Upon death, Raremon turned into an egg, which was taken in by Gabumon. It later hatched into Gazimon.
