=== Rise of the Guardians ===
North first appears sculpting intricate toys from ice before being interrupted by one of his Yetis. The Yeti informs him of a disturbance with the Globe of Belief, prompting North to investigate. Upon arriving in the Globe Room, North discovers black sand scattered around and a shadow darting across the area. Realizing this is the work of the Nightmare King, [[Pitch Black]], North quickly summons the other Guardians.

When the Guardians gather at North's Workshop, he informs them of Pitch’s return. Initially, they are skeptical, with [[Bunnymund|E. Aster Bunnymund]] dismissing North's concerns, especially with Easter only three days away. Meanwhile, [[Sandman (Rise of the Guardians)|Sandy]], the Sandman, notices the Man in the Moon shining above and attempts to alert the group. After several failed attempts to get their attention, Sandy uses an elf’s hat bell to draw their focus. The Man in the Moon confirms Pitch’s return and reveals the need for a new Guardian. [[Toothiana|Tooth Fairy]] wonders who it could be, while Sandy jokingly suggests the Leprechaun. Bunnymund hopes it isn’t the Groundhog. When [[the Man in the Moon]] announces that Jack Frost is the new Guardian, North appears surprised but optimistic, while Bunnymund protests, arguing that Jack doesn’t care about children.

To bring Jack Frost to the Workshop, North devises a plan involving a magic sack and portal. He sends two Yetis and Bunnymund to retrieve Jack, who is successfully "kidnapped" and brought to the North Pole. At the Workshop, North introduces Jack to the other Guardians and explains that he has been chosen as one of them. Jack, however, refuses the offer, resulting in a heated argument between him and Bunnymund. Sandy intervenes, suggesting North speak privately with Jack.

North takes Jack aside and explains the concept of a Guardian’s "center," the essence of who they are and why they were chosen. Although Jack is unsure of his center, their conversation is interrupted by Bunnymund, who announces trouble at Tooth Palace. North quickly prepares his sleigh, and the Guardians set off for the palace.

Upon arrival, they discover Pitch’s Nightmares have raided Tooth Palace, stealing children’s teeth and capturing the fairies. Jack manages to save Baby Tooth from one of the Nightmares before they regroup inside the palace, where Tooth Fairy is panicking. Pitch then confronts the Guardians, leading to a fierce battle. Despite their efforts, Pitch escapes.

Realizing that children are losing faith in Tooth Fairy, North quickly devises a plan for the Guardians to help collect teeth and restore belief. Jack joins their mission, and the group embarks on a global quest. While collecting teeth, a friendly competition arises among them, but Tooth reminds them of the importance of leaving gifts. Realizing they forgot to leave presents, the Guardians hastily travel back around the world to make things right.

The Guardians gather in Jamie’s room, inadvertently causing a commotion that wakes Jamie and his dog, Abby. Jamie tries to calm Abby, who growls at Bunnymund. Seizing the opportunity to play a prank, Jack Frost triggers the alarm, prompting Abby to attack Bunnymund, causing chaos as he jumps around the room. Sandy attempts to diffuse the situation with his dream sand but accidentally puts everyone—except Jack, Jamie, and himself—to sleep. When North lands on Jamie’s bed, launching the boy into the air, Sandy catches him and gently puts him to sleep. Sandy and Jack then turn their attention to the sudden appearance of Pitch’s Nightmares, teaming up to fight them.

North awakens and quickly rallies Bunnymund and Tooth to join the battle. As the Guardians confront Pitch and his Nightmares, the fight intensifies. Pitch’s Nightmares overwhelm Sandy, allowing Pitch to strike him, turning him into sand. Enraged, Jack retaliates with an immense ice wave that destroys the Nightmares.

The Guardians return to the North Pole to honor Sandy with a memorial. North encourages Jack to stay strong, reminding him that Sandy would be proud of his efforts. Determined to turn things around, the Guardians shift their focus to helping Bunnymund with Easter preparations. North surprises everyone by declaring that Easter is more important than Christmas this time, which excites Bunnymund. However, when North suggests taking the sleigh to the Warren, Bunnymund insists on using his tunnel system, pulling everyone underground.

At the Warren, the Guardians find Jamie’s sister, Sophie, who accidentally transported herself there with one of North’s snow globes. Jack uses his playful nature to help Bunnymund relax and have fun with Sophie, who eventually falls asleep. Once the Easter eggs are ready, Jack takes Sophie home.

Unfortunately, Pitch’s Nightmares attack the Warren, destroying all the eggs and ruining Easter. Later, Jack discovers the destruction but arrives too late to save the day. Bunnymund tries to impress some children but is devastated to find that he has become invisible due to their loss of belief. When Tooth asks Jack about Baby Tooth and the Tooth Box, Jack admits that Pitch gave it to him. North and Tooth are shocked, while Bunnymund angrily declares that trusting Jack was a mistake.

Later, North, Tooth, and Bunnymund hurried to Jamie’s house to protect the last light of belief. Upon arrival, North was surprised to find Jack already there and even more astonished when Jamie revealed that he could see Jack. When Jack inquired about Bunnymund, North explained that Bunny had transformed into a small, adorable bunny. Jamie laughed at Bunny’s predicament, commenting on how he had gone from tall and strong to "cute." Bunny suspected Jack of putting Jamie up to this, but Jamie clarified that Jack had actually helped him maintain his belief in Bunny.

Pitch then appeared, searching for Jamie. Jack urged the Guardians to protect Jamie while he confronted Pitch alone. However, the Guardians soon found themselves trapped in an alley. Jack, injured from his clash with Pitch, revealed that the Nightmare King had grown stronger. As Pitch approached, Jamie admitted to Jack that he was scared, giving Jack an idea. Jack struck Pitch with a snowball and rallied the group to find Jamie’s friends.

With the Guardians’ help, Jamie’s friends began to believe again. Pitch taunted them, asking who would protect the Guardians while they were busy protecting the children. Jack reassured Jamie that Nightmares were nothing more than bad dreams, inspiring Jamie to volunteer to protect the Guardians. His bravery encouraged his friends to join him. Pitch retaliated with a wave of nightmare sand, but Jamie boldly declared, "I do believe in you. I'm just not afraid of you!" This turned the nightmare sand back into dream sand, restoring the Guardians' powers.

North summoned Yetis with his snow globes, and Bunnymund unleashed his Warrior Eggs through tunnels, joining forces against Pitch’s Nightmares. Meanwhile, Jamie devised a plan to revive the Sandman and shared it with his friends. As the battle continued, the Guardians cornered Pitch, but he slipped into the shadows and ambushed Jack with a nightmare sand scythe. Before Pitch could strike, the Sandman returned just in time, saving Jack and using his dream sand to restore good dreams and strengthen belief worldwide.

With the battle won, the Guardians and children celebrated. Jack initiated a playful snowball fight by hitting Jamie with a snowball. North joined in after being pelted by Caleb, Claude, and an elf. During the festivities, North asked Jack about his center, and Jack revealed he had discovered it was fun. North gifted Jack a small nesting doll as a symbol of his realization, affirming North had always known.

Pitch, regaining consciousness, tried to scare Jamie once more, only to find Jamie unfazed. Jamie walked through Pitch, who retreated in fear to his lair, where the Guardians confronted him one last time. Pitch was ultimately dragged away by his own Nightmares. North then invited Jack to make his Guardian status official. During the ceremony, Jack glanced at Jamie, who nodded in encouragement. Proud of himself and Jamie, Jack accepted, officially becoming a Guardian.

Later, North waited in his sleigh as Jack bid farewell to Jamie. He warmly welcomed Jack as the newest Guardian as the sleigh lifted into the sky, marking the beginning of Jack’s journey with the Guardians.
