"Biggest... biggest fish I ever caught."
Dominic Santiago, after killing a Leviathan

The Leviathan was a species of aquatic animal that lived in bodies of water in the Hollows and later on the surface. These massive beasts were feared by the Locust, who wouldn't go near their territory.[1] Several of these creatures were turned Lambent during the early stages of the Lambent Pandemic, though some remained normal.[2]


Locust WarEdit

Operation: Hollow StormEdit

"You'd have to cross the lake, but nobody does except the Locust. Those waters ain't safe."
Chaps warning Marcus and Dom of the Leviathans

Before being encountered by the COG, the Leviathan territory was avoided by the Locust at all costs, due to the danger of the beast. The Stranded who had headed into the Hollows to seek shelter from the war had some knowledge on them. The Stranded Chaps warned Marcus Fenix and Dominic Santiago about the lake under Mount Kadar and how it was the only way to reach Nexus. Left with no choice but to advance, the soldiers commandeered a Locust craft and began making their way across the water towards Nexus. They fell under fire by multiple Locust Gunboats, and during the confrontation they got their first view of the Leviathan as it pushed their raft towards the edge of the lake. After boarding and capturing one gunboat while the other retreated, they fell over a massive waterfall. Once at the bottom, the Leviathan, which had been stalking them beneath the water, killed the two Manglers that moved the Gunboat and began to attack it, along with the Gears on board, with its tentacles. The two soldiers were able to cut the offending tentacles off with their chainsaw bayonets before they sank the gunboat. Marcus determined that the Leviathan's weakpoint was its eyes and the inside of its mouth. When the Leviathan bit onto their boat, they forced its mouth open by shooting it in the eyes, and threw Bolo Grenades down its throat, killing it.[3]

Lambent PandemicEdit

"It's a goddamn Leviathan!"
Marcus Fenix's reaction upon discovering the CNV Sovereign's attacker

Near the beginning of the Lambent Pandemic, while investigating the Sinking of the Harvest, Marcus Fenix remembered his and Dominic Santiago's encounter with the Leviathan in the Hollow and wondered if one was responsible. Marcus suggested that as the Leviathans were sea creatures, flooding the Hollow wouldn't have killed them and instead may have allowed the Leviathans to escape into the open water. However, they were unsure if there was any more of the creatures other than the one they had killed in the Hollow. Nevertheless, Marcus had a warning passed onto the CNV Clement to keep an eye out for possible Leviathans.[4]

While trading Jonn Massy, the Clement pinged something with strange acoustics, causing Commander Garcia to ask Marcus about the Leviathans, but Marcus didn't know what they sounded like underwater. With the strange acoustics continuing, Garcia questioned if Marcus was sure about the Leviathan and he admitted that he wasn't, but promised to keep an eye out while Dom tried to reassure himself that the Leviathan they encountered had to be a freshwater creature and they should be safe in saltwater. The strange acoustics ultimately proved to be a Gorasni submarine, the Zephyr and not another Leviathan.[5] While discussing the situation with Chairman Richard Prescott, Colonel Victor Hoffman was relieved that it had turned out to be time-forgotten Indies instead of a Leviathan.[6]

Later, three Lambent Leviathans attacked Vectes carrying Polyps. The first was killed after a King Raven emptied an entire belt of chain gun ammo into its head. The second was killed by a combined torpedo attack from the submarines Clement and Zephyr, and the third and final Leviathan was killed by a blast from the Hammer of Dawn.[2]

Another Lambent Leviathan later attacked New Jacinto. COG forces attempted to use the Hammer of Dawn to defend themselves, but the satellites failed, forcing them to find another way to destroy the creature. It was eventually chased to the surface by depth charges and killed by a grenade being thrown down its throat.[7]

During the First Battle of Azura, the Locust used a Leviathan to ferry a recon patrol around the island in a wooden barge before their assault. The Leviathan barge was spotted by KR Zero-Five and warned the island about it. When the King Raven returned to the island after spotting the barge, the Malestrom Barrier was dropped to let them through, allowing the Locust to see the island briefly.[8]

In a separate incident, yet another Lambent Leviathan attacked the CNV Sovereign and was killed after Damon Baird maneuvered a cargo container of Tickers and dropped it on the Leviathan. The resulting explosion destroyed the Sovereign and Centennial Bridge. This one was said to be twice the size of the other Leviathans.[9]

Voyage to AzuraEdit

"It's got us! That son of a bitch is pullin' us by the tail."
"Shoot it in the mouth!
Dizzy Wallin and Marcus Fenix as a Leviathan in the Serano Ocean tries to pull them down with its tentacle

A regular Leviathan attacked Delta Squad's submarine on its way to Azura. After dealing with a swarm of Manglers, it attempted to bite the submarine, but narrowly missed. It chased the sub through a minefield and through narrow archways where it tried to bite through the hull. The Gears retaliated by taking advantage of its gaping mouth and directing their fire into it, while the Leviathan got stuck in the archways of the underwater cave. Unable to reach the sub, it resorted to attempts to crush the submarine with its tentacles. The Gears kept shooting to fend it off and it was finally killed when it caused the tunnel rock to collapse and crush it while attempting to take down the sub.[10]

Current FateEdit

Though all of the Lambent Leviathans were wiped out by the Imulsion Countermeasure Weapon,[11] it is unknown if the surviving Leviathans that were not turned Lambent were also affected and if so, what they may have turned into as part of the Swarm. It is also unknown how many Leviathans remained normal by the time that the weapon was detonated.


The Locust's word for the Leviathan.


The Leviathan had an incredibly thick hide, capable of resisting small arms fire and explosions. It's only viable weak points were its eyes and mouth. In their natural state, they were territorial predators, only attacking those who came too close.
