Ancient Sea Behemoth

The Hibernating Leviathan of Mahri Nui

The colossal sea creature woken by Kongu's Zatth, which fought and then joined the giant venom eel before the Toa Mahri beat it with a trick of Hahli's Faxon and a well-timed rockfall.

Sea Behemoth is an enormous sea creature from the Great Sea of Spherus MagnaSpherus MagnaA desert world of ancient conflict that became the merger point of the Matoran Universe and Bionicle's true endpoint.. It had been hibernating beneath the black waters for thousands of years until Toa MahriToa Mahri: The Toa Who Saved the UniverseThe Toa Mahri were the water breathing form of the sixth Toa team, transformed by the Mask of Life on the way down to the drowned city of Mahri Nui. They fought the Barraki for the mask and recovered it at the cost of one of their own.

A sleeper of the Great Sea#

When Kongu first saw it, the behemoth was a grotesque creature easily two hundred feet long, like a cross between a whale and the clawed slime-worms that Onu-Matoran miners had run into. It was nothing that had ever swum the seas of Metru Nui, a relic of an age so old that it was probably dwarfed by its fellow creatures back then. (BIONICLE Legends 7: Prisoners of the Pit)

Summoning by the Zatth#

Kongu, who had been reluctant to use his new Mask of Summoning, activated it, and the behemoth answered. (BIONICLE Ignition 9: Battle in the Deep!)

The behemoth didn't stay beaten.

The three monsters caught up with the Toa Mahri at the Cord and attacked all six of them. (BIONICLE Legends 8: Downfall)

Kongu tried to summon another creature to fight the behemoth but conjured only a swarm of small glowing fish, which the behemoth found irresistible and ate. (BIONICLE Legends 8: Downfall)

Then Kongu set off a sudden explosion of rocks that stunned the creature, and it was beaten. (BIONICLE Legends 8: Downfall)

Behaviour and threat profile#

The behemoth acted on instinct. It fought what was in front of it, ate what it could catch, and showed no sign of a plan. Its appetite for glowing prey was the weakness the Toa used to beat it. (BIONICLE Legends 7: Prisoners of the Pit; BIONICLE Legends 8: Downfall)

Unlike the Barraki, the behemoth had no history with the Toa or the Pit. It was dragged into the story by accident, through Kongu's reluctant use of a mask he hadn't yet learned to control, and twice the Toa Mahri had to deal with it on top of everything else. (BIONICLE Legends 7: Prisoners of the Pit; BIONICLE Legends 8: Downfall)

It wasn't killed. After the fight at the Cord the story moves on, and the behemoth is left alive somewhere in the seas of Aqua MagnaAqua MagnaThe endless ocean where the Matoran Universe found refuge and Mata Nui made his final stand.. (BIONICLE Legends 8: Downfall)
