Ever played Phantasy Star 4 ? The hardest boss I have ever even imagined has to be Lashiec from PS4. Not Dark Force, but Big Daddy Lashiec. Maybe I was always underlevelled; I don't know. But what I do know is this: Whenever he used AnothrGate, he killed my ENTIRE BLOODY PARTY (except for Wren). There is nowhere at that point in the game that you can purchase items that restore party members to life or heal multiple party members. It takes me up to an hour to beat him, even using emulator savestating. All to get the Eclipse Torch. One use, mild holy/fire damage. YEARGHBLBLBE!
Oh, and any boss in Undead Line for the Genesis. God, my nuts never felt the same after playing that game.
