When the Toa journeyed to Makutas's lair in Mangaia, they encountered a group of Manas controlled by him. The only way the Toa could defeat them was by merging into the Toa Kaita: Wairuha and Akamai. Two of these animals were later encountered by Toa Onua Nuva and Turaga Whenua during their search for Kanohi Nuva. Karzahni also had several Manas in his realm.
These Rahi were attracted to heat. In the wild, Manas tended to turn on each other when they ran out of opponents to fight. At one point, Onua was able to pit a Kofo-Jaga against some Manas to defeat them.
- The Manas are the most powerful guardians of the evil Makuta! No single Toa can hope to withstand this crab-like beast's fieice claw--only by combining their powers and skills can the Toa hope to prevail. When they aren't fighting the enemies of Makuta, the Manas stay combat-ready by challenging each other to awesome battles! Like all Rahi, the Manas can be defeated by knocking of their infected masks. No one knows if a mask-less Manas can be tamed, however, because no one has ever survived an encounter with Makuta's guardians.
- The Manas were released as a boxed set in 2001. Its set number was #8539, and consisted of 442 pieces. Both Manas could be combined into a Mana-Ko model.
- The Manas were the only BIONICLE sets which could be controlled by remote control.
- Each Manas possessed two poweress Kanohi: either two orange Noble-style Ruru or two yellow Noble-style Komau.
- The Manas set was the most expensive set released in the original line, along with 2009's Skopio XV-1.
- In the Mata Nui Online Game, there were several Manas on the way to Mangaia which the Toa Kaita had to battle. They destroyed them by destroying strange poles that controlled them.
- The Manas were the only Rahi not found on BIONICLEstory.com.
