Sea Serpent
The sea serpent is a legendary creature that appears in Tomb Raider Legend. It appears at the worst time for Lara, when she loses contact with Zip and Alister. The creature is huge and is covered in scales. It is also blind; this is how you can trick it. The creature depends more on its hearing then anything else. Even though it can't see Lara it can still hurt her when it spits at her. The creature also knows where Lara is by her footsteps, and will move position and/or place.
People say that it was Merlin, who was turned into a giant snake and left there to protect King Arthur, like the Unknown Enity.
In King Arthur's Tomb the Sea Serpent is a boss which Lara has to defeat in an epic battle. She needs to shoot at bells, then the serpent follows the noise and Lara can pull down with her grapple a cage with spikes which hurts the monster. After 4 times dropping down the cages the serpent dies. Lara could use the corpse to get out of the cave. But then, only a bit later, the serpent appears again in an interactive cutscene (Quick-Time Event) where the player has to push three buttons to escape out of the bad situation. The serpent is caught and goes away.
