Fader Bull are harmless herbivorous bull-like Rahi that could teleport away from danger. It is unknown where these Rahi originally came from and how they came to Po-Metru. They are named because their teleportation leaves behind a ghostly image of themselves that slowly fades away (whenever they feel threatened) and also apparently have a natural power similar to a teleportation Kanoka Disk.
No Matoran on Metru Nui knows why the Fader Bulls have these abilities nor how they control the distance and direction of their abilities, as these Rahi are one of the most difficult to capture and also always cause a constant frustration to the Visorak horde. But in past encounters; Po-Matoran had sometimes stumbled upon a Fader Bull that had materialized inside a rock or other solid objects. The Fader Bull population survived the Visorak's attack on Metru Nui.
