"Greetings mortal... Are you ready to die?"
When I first played Hexen, all those years ago... That was the moment where I got scared, but also curious what was in store for me. I just had to keep playing.

The actual fight against him is pretty sweet, too. Instead of a Cyberdemon-esque "HURR I HAVE LOTS OF HP AND SHOOT EXPLODING THINGIES AT YOU" slugfest, he had some clever tricks up his metaphorical sleeve... The minion summoning, the floor-into-lava, the instadeath ground spikes... Just awesome.
