Official Disney Bio

 * Marshmallow is an enormous icy snowman born from Elsa's powers. He serves as a brute bodyguard charged with keeping intruders away from her ice palace. The menacing white beast doesn't say much, but he packs a powerful punch.

Voice
Marshmallow is voiced by Paul Briggs, who was the head of the story for Frozen.

Characterization
Originally, there were going to be more than one snowman similar to Marshmallow, with Olaf being the first member of this snowman army, but was rejected by Elsa because he wasn't threatening enough, very much like how one's first attempt at cooking food often tends to end in disaster but later attempts become more and more successful (they make a brief appearance in the "Bad Elsa" deleted scene where an originally villainous Elsa can be seen interrogating two of "Admiral Westergard"(an early version of Hans, the actual antagonist)'s guards). However, these snowmen were ultimately proven to be too successful, that they ultimately go out of control and start going on a rampage and purposely attacking anyone in their path, something Elsa was against.

Though the concept was kept so at least one Snowman Guard would be in the film, Marshmallow taking that role.

Personality
Just as Olaf represents Elsa's childlike persona, Marshmallow appears to represent Elsa's powerful desire to be left alone. Because of this, he is extremely aggressive and territorial to intruders or others who try to enter the castle except Elsa, whom he was made to protect. He is incredibly devoted to her and this role, and continued this even when he was injured. However in the end of the film, when returning to the ice palace, he is shown smiling and letting out a happy sigh after placing Elsa's old tiara on his head. This possibly hints that while he represents her desire to be alone, he could also contain some aspects of her innocence.

Despite being a highly competent minion for the most part, Marshmallow still has some bumbling edges as seen when chasing Kristoff and Anna, who was able to outsmart the snow beast, having him smacked by a tree.

Marshmallow may also be a bit hotheaded as he became angered and chased both Anna and Kristoff because Anna threw a snowball at him.

Interestingly, in the storybook taking place after the film, An Amazing Snowman, Marshmallow's friendlier personality shown at the end of the film has apparently taken dominance, becoming playful and is shown to have grown a new found friendship with his brother Olaf.

Physical Appearance
Marshmallow is a hulking behemoth of a snow man, whose joints are comprised of ice rather than sticks, unlike Olaf. His fingers are made from rounded icicles and are really sharp like knives, his elbows and knees having sheets of ice on them like knee and elbow pads.

When angered, it is shown that Marshmallow's eye sockets light up demonically and ice spikes will protrude from multiple parts of his body. It is shown that he gains ice spikes on his back, somewhat like the quills of a porcupine or hedgehog, as well as ice growing along his arms. His ice fingers sharpen to become talons, and fangs will grow along his jaw line. This helps make him a more formidable fighter, as well as making him appear more threatening.

Powers and Abilities
Despite being made from snow and ice, he seems to have no real control over it. However, Marshmallow has immense physical strength, which he uses as his primary weapon. He can grow ice from himself, however, in the form of weapons such as spikes, claws, and teeth to compose armor. He also has shown the ability to breathe blizzards of snow from his mouth. When facing one or two or three opponents, his immense strength can give him the upper hand. However, he does have slight difficulty taking on large groups of opponents at one time, due to their strength in numbers and his lack of agility.

Like Elsa, his abilities are (usually) controlled by his emotions. When peaceful, Marshmallow's appearance is smooth and warm, much like Olaf, though still hulking due to his size, but when angered, the spikes and shards are unleashed, and the more his fury, the more deadly ice shards consume his body, making him all the more dangerous and powerful.

The Origins of Marshmallow
"Don't come back!"

- Marshmallow to Anna and Kristoff

After Anna arrives in Elsa's ice palace, the princess tries to convince her sister to return home, to Arendelle. However, Elsa refuses, though Anna remains persistent even after Elsa's frequent requests to leave. With no other choice, Elsa creates Marshmallow as a personal bodyguard to send Anna, her companion Kristoff, and Elsa's first enchanted snowman, Olaf, out of her home, to never return. After Marshmallow kicks them out however, he upsets Anna by throwing Olaf onto a snowy boulder. As revenge, Anna balls up a snowball and tries to throw it at the giant beast, but Kristoff, knowing it is a bad idea, keeps Anna from throwing the snowball, telling her to let the giant snowman be. Anna tells him she is calm and seemingly softens, but the moment Kristoff turns his back, she throws the snowball at the giant snow monster. Though it leaves literally no damage whatsoever, the lack of respect is enough to infuriate Marshmallow, causing him to chase Anna, Kristoff, and Olaf down the northern mountain, most likely to eliminate them.

Marshmallow manages to corner them at the edge of a cliff, though Kristoff immediately begins digging a snow anchor, using a rope to safely guide himself and Anna down the mountain to safety. However, Marshmallow catches up to them, though Olaf tries to stop him. Annoyed, Marshmallow kicks Olaf over the cliff, and continues his chase for Anna and Kristoff, pulling them up to his face by the rope, and ordering them once more to never return, just before Anna grabs Kristoff's knife, cuts the rope, then sends the duo plummeting down, though they survive. With his mission to drive them away complete, Marshmallow returns to the ice palace.

The Attack
Later, Marshmallow stakes himself outside of Elsa's castle, disguising himself as snowy boulders in case more unwanted guests were to arrive. Eventually, they do, in the form of the conniving Prince Hans and his army, set on finding Anna and capturing Elsa. The moment they come close enough, Marshmallow reveals himself and jumps right into battle. The soldiers immediately attack the beast with their arrows, enraging Marshmallow and causing his ultimate form to be unleashed. Marshmallow is able to hold most of the guards off, though, Hans proves to be a fierce warrior himself, avoiding each of Marshmallow's attacks and eventually using his sword to slice the snow monster's leg off, causing him to lose balance and begin tumbling over to a large gorge. With Marshmallow wounded, Hans begins heading inside Elsa's castle, but Marshmallow doesn't give up, giving one last swing in attempt to drag Hans down with him. Unfortunately, he fails, and the giant snow beast plunges down into the chasm below, apparently to his death.

Marshmallow Returns
After the credits, it is revealed that Marshmallow had survived the ordeal, and is seen limping back into the castle with a new made leg where all he finds is Elsa's crown. The monster looks around for a moment and smiles. The monster, pleasing his inner prince, happily crowns himself ruler of the castle, causing his ice spikes to disappear as he gives a happy sigh, happily continuing his life in the North Mountains as its ruler.

Trivia

 * Originally, Marshmallow's render bore a greater resemblance to Olaf, where his body was divided and less smooth, and his arms were made from uprooted tree trunks with their roots as his claws and lacked icicle spikes, and simply roared at Anna.
 * Originally, Olaf was meant to name Marshmallow upon their first meeting in Elsa's castle, as well as deem him his brother. However, this is dropped in the final film. Nevertheless, Olaf is still the only character in the film to refer to Marshmallow by his name, thus keeping the naming of Marshmallow in the film, but in a much different way. This would mean that, though Elsa created Marshmallow, she never named him.
 * Marshmallow bears some resemblance to Hydros the Ice Titan from Hercules.
 * Due to their similarities, his naming may be a reference to the Stay Puft Marshmallow Man in Ghostbusters.
 * It can be argued that the snow creature may not realy have a name as Olaf gave the snowmonster it's name as a brife off bet pun, saying "We totally lost Marshmallow back there."
 * Olaf naming Marshmallow's scene was shown in the junior novel, not in the movie.
 * Before the concept of using a giant snowman as a giant monster, said snowman was originally going to be a polar bear.
