2. Diablo

Evil incarnate

When you’ve got three games and several expansions named after you, of course you’re nothing less than a gaming legend.

Diablo, the Lord of Terror, is the big bad of the Diablo series. As the youngest of the Prime Evils of the Burning Hells, he was responsible for much of the horror that was visited upon the mortal world of Sanctuary. He is not only powerful, but also a keen strategist and manipulator, orchestrating events so that they always fall in his favor.

Perhaps most importantly, he is extremely resilient. Diablo’s many enemies – including the Horadrim, the Angels of the High Heavens, and occasionally even his own demonic brethren – have all tried to destroy him, but failed. Numerous times, he has bounced back from defeat even mightier than before. There is nothing more dangerous than a villain who just won’t stay dead.
