Neutral B: The HMS, puts on the blast mask, which starts to charge up and after a bit explodes. The HMS can move and attack normally while the mask prepares its blast, but he can’t use any of his B moves. When it detonates, the blast radius is fairly large, but the HMS has to be in front of the opponent to get a good hit in. The HMS will be knocked back to the ground after it explodes.
Forward B: HMS puts on the Keaton mask, which summons a Keaton near HMS’s feat, which will rush forward across the ground. If a opponent gets in the way, the Keaton will jump and latch on top them, biting them several times. The opponent will take damage, and if they move around a lot, they can shake of the Keaton before it gets in extra hits. When it’s done, it disappears.
Up B: HMS puts on the Breman mask, which causes a cloud of about four to five chickens. If in air, the chickens will fly up, taking the HMS up with them, before dissipating, and flying off the top of the screen. If on the ground, the chickens will simply fly up, but will damage any opponents that they fly into.
Down B: HMS puts on the Great Fairy Mask, and if he sits still, little ferries will start to float around him. When HMS touches them, he will regain health, but any ferries not touched will start to fly away. They can be caught though if HMS is fast enough, but it can leave him opening.
Final Smash: HMS puts on the Majora’s Mask, and the moon starts to slowly fall down on the stage, much like the Banzai Bill from the Peach’s castle stage. It has a much larger effect though, due to it being a FS.
