Pridak

http://upload.wikimedia.org/wikipedia/en/2/2b/Pridak.jpg Undisputed ruler of the Barraki dating back 80,000+ years. Mind as sharp as his teeth. Extremely fast underwater and a perfect killing machine. More than willing to use violence to enforce discipline -- in addition to blinding Kalmah in one eye, once bit Nocturn's arm off. Learns from his mistakes. Expert at holding a grudge. Feels entitled to power, and is willing to defy even Makuta to his face. Feels no guilt or regret over anything he does. Hot-tempered, but also practical -- sees no reason to kill Matoran if there is nothing to be gained by it (hence the survival of Mahri Nui all this time). If there is something to be gained by it, would calmly order destruction of entire village and sleep peacefully that night.

Pridak commands an army of Takea sharks. His favourite hunting grounds are at the Pillars of Salt in the northern edge of the city.
