10 Best Video Games With An Unseen Enemy
7. Doom
Though Olivia Pierce is the villain of the 2016 Doom reboot, and the Khan Maykr is the primary antagonist of sequel Doom Eternal, ultimately both ended up making a pact with the series' real Big Bad, who is only revealed in Eternal's two-part campaign DLC The Ancient Gods.
There we finally meet the one behind everything - the Dark Lord himself aka Davoth, the supreme ruler of Hell who made a pact with Pierce to open portals to Hell on Mars, and granted the Khan Maykr enormous power in exchange for more worlds to enslave.
Davoth eventually reveals that he created the multiverse and everything in it, including Earth, Mars, Hell, and so on, and also bears a notable physical resemblance to the Doom Slayer himself.
But the most curious thing about the Dark Lord reveal is that, considering Eternal confirms we're playing as the same Doom Slayer from the original games, that makes the Dark Lord the overarching antagonist of not just the "reboot" franchise but the entire series dating back to its 1993 debut.
With the Dark Lord killed at the end of The Ancient Gods, it'll be interesting to see where things go from here.
