Crystal King

The Crystal King appeared in 2000 video game called Paper Mario. The Crystal King is the final boss in possession of a Star Spirit that Mario had to face before his final confrontation with Bowser in the game Paper Mario.

The Crystal King is invisible, save for his robe, crown and floating yellow eyes. He can disappear and reappear altogether in a flurry of snowflakes.

The Crystal King is exceptionally powerful. He can levitate, summon Crystal Bits to use as ammunition and shoot freezing beams. In desperation, the King can make fake clones of himself and recover his HP; if not beaten quickly enough, the Crystal King will recover 20 HP at least three times, and he and his army of illusory copies will unleash a powerful blizzard attack. There is no way to tell the Crystal King apart from his clones, leaving Mario to guess or use an attack that hits all enemies.
