Notes:

The text in the upper left reads as follows (bracketed text mine);

"Made by an anon who really wanted to put his actual nickname here, but since he's [talked(?)] about this chart in [/aco/] already, he's too paranoid he'll be hunted. So, uh, enjoy."

And the Prower (between Hayden and the Pinky) and the Harvester (between the Cacodemon and the Revenant) are demons exclusive to multiplayer and totally should have been included in the main campaign.
