Instead, I am instantly reminded of a different entity from a different franchise: the Destroyer, from the Marvel movie Thor.

Re-reading this spork, I just realised what I'm reminded of. An RPG in which the player attempts to play through a part of the game they weren't supposed to be able to access until right at the end when they're at level 97 and ends up running away from the boss fight when they realise they done fucked up.
