Plot
It is Christmas Eve in New York City. While Peter, Harry, Miles and Humberto are helping with the Christmas Party, Mary Jane is with Aunt May, Rio and Scott Lang’s wife Maggie watching a junior Stage-play show based on The Nutcracker and the Mouse King on which Scott’s daughter Cassie is playing Marie the ballerina. Everything appears to be a calm night until Squirrel Girl comes and alert the boys, who come out and watch in disbelief as a giant nutcracker puppet is walking around the streets.

Putting on their superhero forms, Spider-Man and his team stop the puppet, which magically turns back into its true form as a regular puppet. They are approached by Doctor Strange, who informs them that toys across the city are coming to life due to the effects of the Reality Infinity Stone, which accidentally feel in the hands of a human child who is carelessly unaware of its power. Followed by the Avengers (Captain America, Ant-Man, She-Hulk and Tony Stark’s first A.I. J.A.R.V.I.S. (now a synthetic android named Vision)), the team expects to find the child and retrieve the Stone. Captain America also warns the young heroes that he heard that there are two villainous wizards who are after the Stone: one is Doctor Strange’s first enemy Kaecilius, who seeks the Stone to free the Zealots, and Spider-Man’s old foe Mysterio, who was presumed dead after his confrontation with Spider-Man until it was revealed that Quentin Beck, the Mysterio helmet’s host, was only entrapped in the helmet's dimension and is seeking the Stone to fulfill his debt with Dormammu.

The group explores the city in search of the child, although they are ambushed and challenged multiple times by Kaecilius and Mysterio; the two mad wizards are also competing against each other for the Stone’s power. The heroes are joined afterwards in their mission by Phoenix Princess, Cyberstar, Ms. Marvel and White Tiger as they work to keep the hexed toys under control. The behavior of the sentient toys properly reminds Scott of how his daughter Cassie plays with her own toys, leading Peter and Mary Jane to the possible conclusion that Cassie has the Stone. This fact is proven correct when they spot Cassie, still wearing her stage-play costume to enjoy Christmas, wearing a Red Diamond Tiara. And Jocasta confirms that the gem is in fact the Stone.

The young couple approaches Maggie and, after some talk about the situation, they manage to switch the Tiara with the Stone with a normal tiara Mary Jane creates with her Phoenix Powers. After they deliver the Stone to Agent Hill for S.H.I.E.L.D. safekeeping, Spider-Man and Phoenix Princess gather with their teammates and join the fight against Kaecilius and Mysterio, whom Spider-Man defeats by separating Beck from the Mysterio helmet and convincing Beck to start living a normal life. Facing defeat by the heroes’ hands, Kaecilius takes over the Mysterio helmet eager to achieve true power, but only to become a slave of Dormammu (as Doctor Strange previously warned Spider-Man about) and get sucked into the Dark Dimension. Doctor Strange takes the helmet to the Sanctum Sanctuary for safekeeping as the young heroes enjoy their night. They are visited by Jolnir (also known as Santa Claus), who praises the young heroes for their work before he and Spider-Man together go delivering gifts for children in New York. With one hour left before Christmas, the young heroes enjoy a peaceful Christmas party with Aunt May, Maggie, Cassie and the Avengers. During the event, Cassie properly puts a small mistletoe between Peter and Mary Jane, getting them both to share a passionate kiss.
