create one!

The Leviathan - a colossal, serpentine creature that lurks in the abyssal depths of the ocean. With glowing, hypnotic eyes and rows of razor-sharp teeth, the Leviathan is said to be able to swallow entire ships whole with a single gulp. Legends say that its scales are impenetrable, and its roar can cause tidal waves and storms to wreak havoc on the seas. Sailors who have encountered the Leviathan and lived to tell the tale speak of a bone-chilling sense of dread and hopelessness that overcomes them in its presence, as if staring into the abyss of their worst nightmares.

i said CREATE ONE! not pick out one that ALREADY EXISTS!

My apologies for the oversight. Here is a new mythical ocean creature:

The Abyssal Shrieker - a horrifying and elusive creature that dwells in the darkest depths of the ocean. With long, razor-sharp tentacles and glowing eyes that pierce through the darkness, the Abyssal Shrieker is known for its deafening, otherworldly shriek that can be heard for miles around. Sailors who have ventured too close to its territory speak of a paralyzing fear that grips their hearts and fills their minds with terror. Legend has it that those who hear its eerie call are doomed to meet a watery grave, as the Abyssal Shrieker lures them towards its lair with promises of dark secrets and forbidden knowledge, only to consume them whole in the icy blackness of the deep sea.

Do another that attacks aircraft carriers and other naval warships

The Sea Titan - a colossal, monstrous creature that is said to prowl the oceans, targeting and attacking naval warships with ruthless efficiency. With massive, armored scales covering its body and razor-sharp fins capable of slicing through steel, the Sea Titan strikes fear into the hearts of even the bravest sailors. It is said to have the ability to create massive whirlpools and tidal waves, capsizing entire fleets with a single swipe of its mighty tail. Legends tell of its insatiable hunger for destruction, as it relentlessly pursues and engulfs any vessel that dares to challenge its domain. The Sea Titan is a force to be reckoned with, a nightmare of the deep that leaves destruction and chaos in its wake.

Do a type of undead horde of the seas that raids warships

The Drowned Legion - a terrifying and relentless horde of undead sailors and sea creatures that haunt the depths of the ocean, rising up to raid and terrorize warships and naval fleets. These cursed beings are said to have perished at sea, their souls consumed by the dark powers of the ocean, turning them into vengeful spirits bound to the watery depths. The Drowned Legion is led by a malevolent figure known as the Ghost Admiral, a spectral commander who wields dark magic and commands the undead forces with ruthless precision.

When the moon is full and the fog rolls in, the Drowned Legion emerges from the depths, their tattered sails billowing in the eerie night winds as they unleash their wrath upon unsuspecting ships. Their skeletal hands reach out to drag sailors down into the icy grip of the ocean, adding to their cursed ranks with each successful raid. Those who survive encounters with the Drowned Legion speak of haunted whispers on the wind, chilling cold that seeps into their bones, and faces of the dead that leer out from the dark waters, a reminder of the merciless wrath that awaits any who dare to cross their path.
