Disks are monsters that have disguised themselves to look much like the unlockable mystery discs (quite possibly a type of Magic in disguise), but they do not actually contain another monster. Disks only appear in Monster Rancher 1 and when transferred over to Monster Rancher 2 become Nitons. There are two sub-breeds of Disk that can be obtained from specific CDs. Merging these two is the only way to get a pure Disk monster without cheat codes. Disk monsters appear in several other games as unobtainable monsters.
Disk Sub-Types Edit
NOTE: Technically, no sub-Breeds can be created through combining in Monster Farm Online or Monster Farm Lagoon, but based on colors and attributes, educated guesses were presented on some of the sub-species for clarity
