Your Worst Nightmare

Your Worst Nightmare is a post-Hybrid boss that spawns when you are in the "Other World", accessed using the DeLorean. He- or it- looks like a glitching Moon Lord that changes colors and changes size. You cannot "kill" this boss, as it only dies when it becomes day again. If you spawn him close to morning, but still night, it wont spawn.

Attacks:
Laser eyes: 200 damage

Crush: 200 damage

Tongue: 270 damage

You cannot go to the DeLorean before Your Worst Nightmare has been killed.

When Your Worst Nightmare has been killed, this message will appear in the chat: "The Ruins are spreading!". Five minutes after this message, this message will appear: "The glitches grow...", which will make the Glitch and the Ruins spread in your world before you entered the DeLorean, which you can access by going back into the DeLorean
