The Barraki were six powerful rulers who were condemned to the Pit and fought the Toa Mahri for possession of the Mask of Life. They were Pridak, Ehlek, Kalmah, Takadox, Carapar, and Mantax.
"Barraki" was a title, not a species name, and was the Matoran word for "warlord."
Banished to the Pit 80,000 years ago, the Barraki warlords waited millennia to have their revenge on the universe. They were armed with incredible knowledge of battle tactics and vampiric squid launchers.
Once, long ago, the Barraki lived on land. They were, in fact, the rulers of six powerful kingdoms. They were later exiled to the Pit for crimes against Mata Nui. They escaped, but they were mutated by a strange substance in the sea water into the forms they came to have. Each looked different because each one was a member of a different species. The Barraki were no longer able to breathe air, so they had to live underwater. Some of their weapons they found, and the rest they made themselves. Each Barraki had added a special feature to his armor that allowed him to clip living squid on and carry them as ammunition.
The Barraki's best tool was their ability to sneak up on a foe.
At one time, the six Barraki were warlords and kings who ruled over their own realms on land. They attempted to rebel against Mata Nui and were defeated by the Brotherhood of Makuta. They were banished to the Pit for their crimes. When the Great Cataclysm released them from the original Pit, they were mutated by the ocean waters into hideous, water-breathing creatures. After this mutation, they could not hope to regain their kingdoms unless they found a way to reverse the changes. They commanded armies of sea creatures in the waters of the Pit. When the Mask of Life sank into their realm, they seized it believing it could restore their original forms, allowing them to resume their conquest of the Matoran universe.
For any team of Toa to defeat the Barraki was a daunting task. Each of them was a cunning and dangerous foe, with detailed knowledge of their environment and how to leverage it in combat.
The Barraki once formed an alliance called the League of Six Kingdoms and ruled a significant portion of the known Matoran universe. They attempted to overthrow Mata Nui 80,000 years ago but were defeated by an army led by Makuta Teridax. Before they could be executed, Botar transported them to the Pit. The Barraki remained imprisoned in the Pit until the damage caused by the Great Cataclysm allowed them to escape. Once free, they found themselves stranded at the bottom of a strange ocean with no air for them to breathe. However, a mutagenic agent in the waters severely mutated them, making them able to breathe only underwater and to survive at great depths. Unable to leave the ocean, the Barraki formed underwater armies of sea creatures and plotted revenge against Mata Nui and the Brotherhood of Makuta. After the Matoran city of Mahri Nui sank into the upper part of the Pit, the Barraki periodically hunted its Matoran for sport.
When the Kanohi Ignika drifted down into the Pit, the Barraki seized the mask, knowing that its power could transform them into their former selves and allow them to reclaim their kingdoms. The Barraki entrusted the Ignika to Nocturn, who lost it. The Toa Mahri tricked the Barraki into warring among themselves, giving them time to search for the Ignika. The Barraki realized their error and banded together to battle the Toa Mahri for possession of the Ignika.
Before their mutation, each of the Barraki was originally an impressive, perfect physical specimen.
Pridak was the leader of the Barraki.
Teridax held the Barraki in disdain, considering them to be bunglers who lacked finesse.
