well,  basically it's a battle against an enemy that is far too large to sprite, so instead of facing the boss in a traditional manner one faces parts of the boss (like an arm, leg, head or foot) : it has been done before in games but like so many things it's about the limits of both what one can make in a sprite-based game and the RPGMaker itself.

Nebula in Worry's Quest.. all I can imagine is Attack on Titan or Shadow of the Colossus.
