Metal Face

Metal Face (, Black Face) is a major antagonist in.

Origin
Metal Face first appeared in  during the attack on Shulk's hometown,. He is immediately identified as the biggest threat, but nothing can be done to stop him; he easily destroys all the weaponry used against him and kills many, including Shulk's childhood friend Fiora. During the attack, Metal Face displays unusual cunning for a and an immunity to the Monado, which is otherwise the only weapon that can harm Mechon, making him practically invincible. After the attack is over, Shulk leaves Colony 9 to chase him down for revenge. When they next meet, he shows that he can speak by taunting Shulk over enjoying his killings, and only leaves because of external interference. It is later revealed that Metal Face is a shell controlled by, a traitorous former war buddy of Dunban who was presumed dead after the Battle of , and doesn't particularly care for the orders he's given, as long as he gets the Monado in the end.

Metal Face is a card-carrying villain, relishing the pain and suffering he causes for its own sake. He openly gloats to Shulk and the others about the people he killed in front of them simply because he felt like it.

In
Metal Face first appeared as a shadow at the end of Shulk's reveal trailer, teasing his role as a stage hazard on Gaur Plain, which was confirmed in the Direct.

Metal Face has a random chance of appearing shortly after nightfall. When he does show up, he will either perch himself at the center of the stage, or fire his Grand Shot to destroy one of the top platforms, then land on the smaller ones beneath. Once in place, Metal Face will unleash a wide-ranged Killing Claw at any fighters that get too close to him, but will not actively chase anyone, instead preferring to sit back and enjoy the show. He can be defeated by attacking him, and when that happens, he will burst into a series of explosions and fall to the bottom of the stage, dealing heavy damage and knockback to any fighters in range who didn't land the final hit on him. If he is not destroyed before dawn, he will leave the stage, sometimes with a "parting gift" in the form of a dashing slash along the horizontal length of the stage.

Metal Face is a very noisy stage hazard, with an extensive set of voice lines for when he arrives and departs, attacks anyone nearby, and gets attacked or destroyed - he will even taunt the fighters if no one approaches him. If Shulk happens to be in the battle, Metal Face will have special voice lines directed at him. For a full list of quotes, see here.

In Smash Tour
Metal Face appears as a random event: bumping into him will initiate a battle against him in Gaur Plain. If not defeated in time he flies to another spot in the map, but he retains any prior damage.

Trophy
Metal Face's trophy is part of the Mechonis Trophy Box.

In Super Smash Bros. Ultimate
Metal Face returns as a stage hazard in Super Smash Bros. Ultimate.

Spirit
Metal Face also appears as two primary spirits, including his Mumkhar form.

In Adventure Mode: World of Light, Mumkhar is presumably one of the countless spirits captured by Galeem during his takeover of the universe. After Galeem's defeat, Dharkon takes control of Galeem's spirits, including Mumkhar. After Dharkon's defeat, he flees to the final world, with Galeem following soon after. In the final world, Galeem and Dharkon wage war against each other using their captured spirits, with Dharkon taking control of Mumkhar.

Mumkhar's Spirit Battle uses a puppet fighter and is fought on the Gaur Plain stage. During the battle, Wolf will turn Giant and Metal when at high damage, referencing Mumkhar's ability to transform into his giant Faced Mechon, Metal Face.

Metal Face can be obtained by enhancing the Mumkhar spirit at level 99.

Trivia

 * One of the tips in the Wii U version of the game mentions that whoever KOs Metal Face gets credit for the KO, like Ridley. This is likely a leftover from earlier in development, as it does not occur in the game. Metal Face also has an unused head icon in the same style as Ridley, suggesting that it was intended to be used like Ridley's when a player KO's Metal Face.
 * Metal Face has a total of 49 voice clips, by far the most of any non-playable character, and more than many playable ones.
