Cthulhu



 is a fictional cosmic entity originally devised by author, as an evil god from beyond the human universe. The creature remains a popular element of today.

Cthulhu was a possible boss. Re-Logic was considering its addition at one point, but he was replaced by Moon Lord. While Cthulhu itself never made an appearance in Terraria, a number of enemies and items include direct and indirect references to Cthulhu. However, some might think that moon lord is Cthulhu. And for good reason. Its stated in the official lore that the dryads ripped apart pieces of Cthulhu. After this, Cthulhu retreated to the "Dark side" of the moon to gather strength. This could suggest why he is mostly intact despite the damage the dryads did.

While we never see Cthulhu we do know some things about him from his organs. Cthulhu has blue eyes. (Unless he has Heterochromia iridum). He has a heart located in his brain.

Trivia

 * In the concept art, he is missing one of his eyes, presumably because the missing eye became the Eye of Cthulhu boss.
 * One of the title messages on the refers to this: ""
