Mighty Avalanche (アヴァランチブレス, Avaranchi Buresu?, lit. "Avalanche Breath") is a Team Attack that appears in Kingdom Hearts III. It allows the user to team up with Marshmallow and attack the enemies with ice attacks.
In Kingdom Hearts III, Mighty Avalanche is a Situation Command used by Marshmallow and Sora while Marshmallow is in the party. When used, Sora jumps on Marshmallow's back and Marshmallow covers himself in spikes, upon which Marshmallow can be freely controlled to slowly move around. While the Situation Command is active, the user can charge at enemies while swiping their claws to deal Physical damage with Ice Rampage, jump in the air and leave a shockwave upon landing which deals Aero damage with Jump, end the Situation Command with Cancel or initiate the finishing move with Finish. If Finish is not used within 20 seconds, the Situation Command will automatically end. Marshmallow and Sora are invincible while using this Situation Command.
When the Finish command is used, Marshmallow spins around and creates a field of ice crystals around himself which then shatter, freezing any enemies caught for 5 seconds and dealing Blizzard and Aero damage, upon which the Situation Command ends.
