Moon Lord

The Moon Lord is a boss that is battled after all four Lunar Events (vertex pillars) have been defeated, serving as a "final boss" to the game.

When fighting the Moon Lord take caution as he shoots out True Eyes of Cthulhu serving as hazards shooting lasers at the player. Much like Skeletron the Moon Lord has two hands and a head, though unlike Skeletron the head does not charge at you nor do the hands.

Tips

 * One should be wary of his mouth, as it will attach a tentacle to the player and pull two kill-able essence-like monsters out of the player. If not killed by the time they reach the mouth, the Moon Lord's Head is healed for 1000 health for each of them.

Trivia

 * The Moon Lord shoots out "True Eyes of Cthulhu", hinting that the Moon Lord could be Cthulhu, however this is unlikely as it was confirmed that Cthulhu would not be in 1.3.
 * The boss was originally planned to be the moon itself descending on the world, however Cenx later stated this plan had been abandoned in favor of a different concept, presumably the Lunar Events.
 * This old concept could possibly be a reference to The Legend of Zelda: Majora's Mask.
