My Black Crusade game doesn't have a main antagonist yet. Their biggest struggle was on my heavily extrapolated version of Messia where they plotted against an OPEC like cartel of Mekontan Promethium barons that dominate the city as Quasi-immortal liches trying to cheat death forever (since Mekonta has no concept of inheritance or transfering power so their entire cartel would collapse on their deaths) through imported juvinat, life support machines and shutting themselves away from the world (and it's toxic air)
I've been playing with the idea of the big unseen antagonist being an Eyes of the Emperor masquerading as an Alpha Legionare who pays them and gives our missions while manipulating them for some long game but I can't think of what long game.
