That's not quite all of them. Hunter of Heroes, Maker of Ruins, Eater of Dreams, Slave to Unreason, Eater of Gods (3 versions), and I think there might have been one more. But whether you look them all up or just a few, it should give you an idea (as well as boost your insanity rating by 50%
)
Eater of Gods doesn't look like much until you look at the physically weaker versions and check the ability named True Ethereal...
All of these can be found in the Unit DB.
Easiest way to do is mod the start sites of EA Mictlan (sites 130-133, iirc) and use 5x #homecom <nbr> on each to put the doom horror numbers there and start a game with the mod enabled. It'll show you all of them in one recruitment screen.
