A sleeper of the Great Sea#

The AncientAncientAncient is a dark blue and gold operative who served as both an agent of the Order of Mata Nui and a member of the Dark Hunters, armed with Kanoka and a Rhotuka. Sea Behemoth was a marine creature on a scale unmatched by any other RahiRahiThe Rahi were the biomechanical wildlife of the Matoran Universe, built largely by the Brotherhood of Makuta, ranging from background fauna to engineered war beasts. in the waters surrounding Mahri NuiThe CordThe stone Cord linking Voya Nui to the sunken peninsula of Mahri Nui, the tunnel the Toa Mahri descended, and the lifeline severed to revive Mata Nui., large enough that the chronicles of the period consistently refer to it as a behemoth rather than by any taxonomic name. The records native to its species were thin. It belonged to the Great Sea of Spherus MagnaBara MagnaA desert world of tribal warfare and scarce resources, one of three landmasses that formed Spherus Magna., the body of water that, in the post-Shattering geography, covered most of the surface from which Aqua MagnaBara MagnaA desert world of tribal warfare and scarce resources, one of three landmasses that formed Spherus Magna. had been drawn. The Behemoth had occupied the deep waters there for an unbroken stretch of several millennia in a dormant state, untouched and undisturbed by the upheavals of the surface, the rise and fall of settlements above it, or the comings and goings of the BarrakiThe BarrakiSix warlords who built an empire spanning most of the Matoran Universe, fell in a single Brotherhood ambush, and spent millennia mutated in the Pit. and their forces in the same waters.

The trigger for its waking was external. The Kanohi ZatthZatthGreat Kanohi mask of Summoning, allowing its wearer to call a random local animal for aid without control over which creature responded or its actions. was the Mask of Summoning, an instrument that drew the nearest available creature of the wielder's class to the wielder's location, and its scope was not always under the wielder's control. The combination of the ZatthZatthGreat Kanohi mask of Summoning, allowing its wearer to call a random local animal for aid without control over which creature responded or its actions.'s call, the depth at which the Behemoth was hibernating, and its sheer mass produced the only outcome the records have to report: the Behemoth answered, rose, and emerged into the fight already underway.

The mask was a power he had been unwilling to call on, in part because the ZatthZatthGreat Kanohi mask of Summoning, allowing its wearer to call a random local animal for aid without control over which creature responded or its actions.'s summoning could not be narrowly focused and tended to draw whichever creature of its target class was nearest, regardless of suitability or scale. The pressure of the fight overcame that reluctance, and KonguKonguKongu commanded Le-Koro's Gukko Force before a strike from the Kanohi Ignika transformed him into a Toa of Air who later served among the Toa Mahri. activated the mask.

The 300-foot Venom Eel300-foot Venom EelA Venom Eel mutated to colossal size by the defensive reaction of the Ignika, active in the waters around Mahri Nui during the search for the Mask of Life. and the Behemoth, instead of resuming hostilities after their first inconclusive engagement, set the fight aside and began moving in concert.

That earlier accident gave HahliHahliA Ga-Matoran scholar who rose to become Chronicler of Mata Nui, then Toa Inika, then Toa Mahri of Water during the final crises of the Matoran Universe. the opening she needed for the second engagement.

Behaviour and threat profile#

The Behemoth was a sleeper rather than a hunter by inclination. Its waking was involuntary and the recorded encounters all share the quality of a creature responding to immediate stimulus rather than a creature engaged in any larger strategy. Its initial fight with the 300-foot Venom Eel300-foot Venom EelA Venom Eel mutated to colossal size by the defensive reaction of the Ignika, active in the waters around Mahri Nui during the search for the Mask of Life. was a head-on engagement between two predators of comparable scale. Its subsequent alliance with the Eel and with GadunkaGadunka (Species)Finger-sized sea Rahi from the abyssal zones around the Pit, one of which was mutated to enormous size by exposure to the Mask of Life. appears to have been formed without negotiated cooperation, in the same passive way the three creatures' shared Ignika-influence drew them together rather than against one another.

The Behemoth's susceptibility to bioluminescent prey was both its greatest asset, in that it had successfully consumed the swarm of glowing fish offered to it by KonguKonguKongu commanded Le-Koro's Gukko Force before a strike from the Kanohi Ignika transformed him into a Toa of Air who later served among the Toa Mahri.'s earlier accidental summoning, and the precise failing that HahliHahliA Ga-Matoran scholar who rose to become Chronicler of Mata Nui, then Toa Inika, then Toa Mahri of Water during the final crises of the Matoran Universe.'s FaxonFaxonThe Kanohi Faxon, Mask of Kindred, allowed its wearer to mimic the powers of nearby Rahi within the immediate environment. mimicry exploited. The creature was not unintelligent so much as instinct-driven, with feeding behaviours strong enough that they could be replicated and turned against it by a wielder with the right mask. The chronicles record no use of language, no organised tactical responses to the Toa, and no attempt to flee even the situation that finally killed it.

The campaign's leading antagonists, the BarrakiThe BarrakiSix warlords who built an empire spanning most of the Matoran Universe, fell in a single Brotherhood ambush, and spent millennia mutated in the Pit. and their armies, were players of the long game, mutated former rulers with their own factional aims and their own histories with the Toa MahriHahliA Ga-Matoran scholar who rose to become Chronicler of Mata Nui, then Toa Inika, then Toa Mahri of Water during the final crises of the Matoran Universe. and with the PitThe Toa Mahri Descent into the PitThe transformation that ended the Toa Inika, the Barraki's war on the newcomers, and the moment Matoro learned that his Maxilos escort was Teridax.. The Behemoth had no such history. It was a creature out of the deepest waters whose connection to the rest of the chronicled action was entirely accidental, mediated by KonguKonguKongu commanded Le-Koro's Gukko Force before a strike from the Kanohi Ignika transformed him into a Toa of Air who later served among the Toa Mahri.'s reluctant use of an inherited mask whose powers he had not yet learned to control.

For a brief stretch the three largest and most dangerous creatures in the local waters acted in concert, drawn by a common contact with the mask rather than by any planned alliance, and the Toa Mahri only survived the convergence by exploiting individual weaknesses one by one. The Behemoth's defeat by HahliHahliA Ga-Matoran scholar who rose to become Chronicler of Mata Nui, then Toa Inika, then Toa Mahri of Water during the final crises of the Matoran Universe.'s FaxonFaxonThe Kanohi Faxon, Mask of Kindred, allowed its wearer to mimic the powers of nearby Rahi within the immediate environment. was the kind of mask-against-instinct outcome the chronicles repeatedly favour and the kind of moment for which the Mahri NuiThe CordThe stone Cord linking Voya Nui to the sunken peninsula of Mahri Nui, the tunnel the Toa Mahri descended, and the lifeline severed to revive Mata Nui. records most often single HahliHahliA Ga-Matoran scholar who rose to become Chronicler of Mata Nui, then Toa Inika, then Toa Mahri of Water during the final crises of the Matoran Universe. out.

The Behemoth's body, like that of the other two creatures defeated in the same window, was not pursued after the immediate engagement. The destruction of the CordThe CordThe stone Cord linking Voya Nui to the sunken peninsula of Mahri Nui, the tunnel the Toa Mahri descended, and the lifeline severed to revive Mata Nui. and the events that followed soon redrew the entire local geography, and the surviving records do not return to the Behemoth's remains. By the time Mahri NuiThe CordThe stone Cord linking Voya Nui to the sunken peninsula of Mahri Nui, the tunnel the Toa Mahri descended, and the lifeline severed to revive Mata Nui. itself was gone, the waters in which the Behemoth had hibernated for millennia were no longer the same waters at all.
