Kingdom Hearts III
Marshmallow is created by Elsa's strong desire to be alone, taking the form of a brutish snowman. He then promptly evicts Anna, Kristoff and Olaf from Elsa's ice palace, but turns aggressive when Anna throws a snowball at him. However, before he can give chase to the trio, Sora, Donald, and Goofy block the giant and lead him to another area, where they use the area's trees to wallop him. Although they are able to hold their own, Marshmallow manages to corner them on a rocky outcropping, which he breaks off causing them to fall down the mountain.

Later, Marshmallow pursues Hans down the mountain, trying to rescue the kidnapped Elsa, and runs into Sora and his friends. When Sora explains that they are trying to help Elsa as well, Marshmallow helps them down the mountain, shielding them from the growing storm.

Once Hans fails to kill Elsa, the darkness in his heart births the Sköll, which transfers the quartet to a dark area. During the battle, Marshmallow helps repel the Heartless's most powerful attack alongside Sora.

Sometime after Master Xehanort's defeat, Marshmallow catches Olaf, whose parts ended up separated before fixing himself.
