User blog:MarieBilly Archimedes Shears/About my Cthulhu Theory...

I've officially decided against Cthulhu ever being in the game as an actual boss. This video pretty much explains it.

Basically, Cthulhu isn't a giant tentacle-y creature you can defeat. It's the idea of how futile and meaningless our choices can be. Just being able to damage Cthulhu ruins the idea. Because it can't be defeated. It's not something that "exists," per se. It's pretty much represented by the word of Terraria itself in a way. It never truly changes, no matter how many villagers you house or monsters you defeat, there's really no long-term goal. Hope I gave you a new look at Cthulhu! :)
