Imagine having Lovecraftian god as your side-kick.
Psycho Goreman is a creature feature responsible for deaths of billions and worse eons ago before he was imprisoned in Lor-Ncar, a green ball that you can find in the Divide at the Crow's Nest. Psycho is very powerful even in his current punished state, and he has a very unique feature -- he spawns his monster slaves each time he engages into battle. There are two types of them, one is 'regular', and the other only appears if you have Wild Wasteland perk. He also calls upon a scorch beam from the stars to heal himself from time to time that can harm those too close to him. And as a proud owner of an acid heart he has acid in his veins that will splatter when someone hits him silly. So better keep your distance... Unless you arm him with some gun. Yes, our fella can use most of the weapons in game, melee, ranged, throwables. He even has his own giant gory club (Which you can borrow at any moment, for research).
Psycho Goreman is binded to Lor-Ncar. Each time you wear it he's called to you from his abyss, and is banished there each time you take it off. There might be consequencies for using his services too often or for too long. Or maybe there isn't.
PG hates your guts. Nothing personal, he's just superbly annoyed by the fact 'a monkey' is giving him orders.
He's directly inspired by a movie of the same name from Astron-6, where a couple of kids find a similar kind of eternal horror. And force it to do their bidings.
ATTENTION: There's an optional esp included with a more gritty-like PG look called Dark Crimson (Check screenshots). You only need ONE of the esps activated, DO NOT ACTIVATE BOTH.
