|“||This enemy brings chaos to the battlefield, employing three different attack patterns. He'll use magic to help—or hinder—fighters depending on their color. He will also smash platforms with a localized earthquake. Last, he'll directly strike fighters. Wait a sec... What a cheater—he's invincible when he's in the background!||„|
|~ Dark Emperor's trophy description in Super Smash Bros. for Nintendo 3DS and Wii U.|
The Dark Emperor, formerly known as the Dark Lord, is the main antagonist in the Find Mii series. Though he is the mastermind behind the events of the series, he does not appear until the end, where he acts as the final boss of Find Mii II.
Find Mii II
After the defeat of the Ultimate Ghost, the Dark Lord swoops down and grabs the Monarch by the tail. He plans to swallow up all the light in the world, transforming it into a land of darkness. He is defeated by the Hero and explodes.
The Dark Lord reappears in the Secret Quest mode in a more powerful form, dubbed as Dark Emperor, after gaining a tremendous boost in power. He plays the same role as he did in the first game where he is defeated once more by the Hero.
