Mother Demon

The Mother Demon is new in Doom 64. She is the final boss of the game, appearing only once in MAP 30: The Absolution. She is more powerful than any other monster in the game, including the Cyberdemon. She is visually the closest monster in Doom 64 to the Arch-Vile. Her main attack is a set of 4 homing fireballs which split up when when they hit something.
