The Guide, once killed, will fall to the ground, instead of being chopped into pieces, then a message in the chat will appear saying 'You are too much of a terrible person...' then the screen will go dark for 5 seconds. after these 5 seconds the screen will stay dark for 4 seconds as a message appears saying 'I knew this day would come...' as the screen flashes white for the 4 seconds, and once done, the boss will appear

Appearance
The Guide of Cthulhu will appear with his normal clothes, will have eyes similar to the Eye of Cthulhu and green wings.

Phase 1
The Guide will start by flying around, teleporting and using a red recolour of the Chlorophyte Claymore. He will also place ten blocks in a tower-sort-of-way every 15 hits.

Phase 2
Once brought to half health, (10000, meaning it's max health is 20000) the background will turn red like the Wall of Flesh and Wondering Eyes will start to be summoned by the Guide by a 80/100 percent chance.The Wings will turn red and the Guide will use attacks like Retinaser's lasers and the Lunatic Cultist's  Thunder Orb & Fire Balls.

Death
Once defeated, will drop 999 hearts, Blood Wings, (The Red Wings, 45/100 percent chance) Guide of Cthulhu Trophy, (2 red feathers on the trophy, only will drop if some sort of wood-made thing or a tree is in the player's range when the Guide is defeated) and 396 red feathers. Once defeated, the Guide will fall to the ground. You can still speak to him, but he will only say 'why? (groans in pain)'. When far away enough, the Guide will appear on the floor of his house, if he does have a house, and a new NPC called The Guide's Brother will appear, who will stay in the Guide's house with him, meaning there will be 2 NPCs in the Guide's house.
