14 Hardest Retro Bosses of All Time

Pandemonium Warden – Final Fantasy XI (2002)

An encounter so deviously long that a guild’s members fell sick after 18 hours of play. Who else could it be but Pandemonium Warden, the infamous boss from Final Fantasy 11? Pandemonium Warden was absolutely brutal, possessing 20 different forms, each having its own strategy and requiring several hours to defeat. Much like Blizzard and C’thun, Square Enix nerfed the Warden and placed a 2 hour time limit on the fight.
