"Here he is—the undead idol we love to fear... It's the "grim creeper," aka Master Mummy! Master Mummy's story has always been wrapped in mystery...and 500 thread count cotton. He's been searching for answers since he rose from the dead, but will victory bring the closure he seeks?"

Master Mummy is a playable fighter in ARMS. He is a mummy that's been reanimated by Dr. Coyle, searching for his long-lost family.


Master Mummy's tall, bulky body is mostly covered in strips of linen, which also make up his ARMS. He has purple skin as well as purple lips and red eyes with spiraled irises. He wears a purple, one-shoulder wrestling singlet and cyan sneakers. Master Mummy also wears a gold plated helmet with screws on the sides and top, and has strips of linen coming out of the back of his head resembling a ponytail. Master Mummy's ARMS mask features a golden metallic harness bolted onto his head, with more linen and straps to cover the upper face.


"Wrapped up in mystery and bandages, it's 'the grim creeper'! With an uncharacteristically buff body for a mummy, this heavyweight shrugs off punches like nothing. All we know about this guy is that one day he woke up at the Mausoleum and now he's entering the Grand Prix! There's a story there..."
Official description

Master Mummy's motivation for entering the Grand Prix is to reunite with his family. He is known to have a wife and a son.

Dr. Coyle states in her notes that she performed experiments on Master Mummy that ultimately lead to his reanimation, as well as his ability to use the ARMS ability. However, he suffered total memory loss after the process.


When blocking, Master Mummy will heal in 10 health increments; the rate at which he heals will speed up the longer block is held. In addition, he will have super armor and not flinch from attacks that don't force knockdown while jumping, dashing, or punching; he also gains 50% damage reduction when a punch is resisted. Super armor will decrease the initial damage of ARMS as well as resulting explosions from the Explosion attribute, however will not resist additional hits from mutli-hit ARMS (this applies to other characters with super armor as well).

Notably, Master Mummy possess the strongest grab in the game, dealing 200 damage.


The Grim Creeper lives up to his name, as his devastating grab, super armour and massive ARM girth allow him to slowly push and bully opponents into a corner. When you get your opponents into a corner, you can limit their escape options, by shrugging off normal punches while Mummy’s own offense becomes unreactable.

If the situation calls for it, you can also sit back and heal to get down-to-the-wire timeout wins as well as bait unsafe approaches and punish.

ARM Recommendations

ARMS that limit and control the opponent's movement or shut down the opponent's offense work well with Master Mummy. They conceal his own low mobility, and force opponents to play at his pace. Some examples are:

Grand Prix Ending


  • Master Mummy was one of the first characters announced as playable, being revealed alongside the game itself during the Nintendo Switch Presentation on 2017-01-13.[1]
  • Master Mummy was known as "The Powerhouse" instead of "The Grim Creeper" in the original trailer.
  • In the demo build, Master Mummy had the Megaton, Homie, and Revolver.
  • Master Mummy is one of only two characters whose age is unknown, with the other being Byte & Barq.
  • When Dr. Coyle faces Master Mummy in the Grand Prix, it is revealed that she was the one responsible for his reanimation or at least the head researcher of the project who revived him.
  • Master Mummy has the tallest natural height in the game, as the two characters that exceed him, Mechanica and Helix, require special means to do so (respectively, her suit and his ability to stretch himself).
  • Master Mummy is one of the few characters whose voice actor has already been involved within a Nintendo game at the time of ARMS' release. He share this distinction with Ninjara and Mechanica.
    • In his case, Kouji Takeda previously voiced Daruk in The Legend of Zelda: Breath of the Wild. Takeda would later voice Donkey Kong in the Japanese dub of The Super Mario Bros. Movie.
