lore idea for when nocturne,shaco and fiddlesticks get their VGUs

i feel like since they're all supposed to be pure evil embodiment demons, wouldn't it be really cool and unique if they were all the same evil creature? Pennywise, or some love craft creatures come to mind when i think of this, shaco, nocturne and fiddlesticks wouldn't be the creature/demon/evil god himself but they will be essentially "puppets", physical manifestations of the being all over runeterra working toward a single goal...the creature could be semi omnipresent therefore all 3 can exist and interact with each other at the same time but they all share the same soul or core. ive been sitting on this idea for a bit but the three has always reminded me of each other they have their physical differences but their core story all seem to be "kill everything, be pure evil" so im just like why not have them all be manifestations of a single creature? one so hideous and terrifying we cant even comprehend it and these 3 forms are just the tip of the iceberg of this truly horrifying evil creature, it can perhaps be one creatures aurelion sol mentions in his VO "there are terrifying entities in the universe, pray they dont find this world."

just my idea for the 3 spookies
