Dark Emperor is the final boss of the Secret Quest in Find Mii 2. He is a more powerful version of Dark Lord, with 250 HP compared to Dark Lord's 200 HP. The Dark Emperor resembles the Dark Lord but has red eyes and a blue-green skin. He uses level-down gas at the start of each encounter; in order to dispel the gas, a Dispelling Draft must be purchased from the potion service. Dark Emperor also makes an appearance in Super Smash Bros. for Nintendo 3DS.
