Toothiana, or commonly known as "Tooth", is the tetartagonist of Rise of the Guardians. She is a beautiful, elegant, blue and green iridescent fairy. She is half-human and half-hummingbird. Full of energy and always in motion, her feet never touch the ground. Everyone knows the Tooth Fairy collects children's teeth with the help of her fleet of mini fairies that patrol the globe 24/7. What you don't know is that the teeth hold the most precious childhood memories. Tooth safeguards these teeth in her palace and returns the memories when you need them most.
Tooth is a part human part hummingbird hybrid. She has fair skin and violet eyes. Instead of hair, she has feathers that make a curved upward style. Instead of clothes, her entire body seems to be covered in mini feathers. Around her wrists and ankles, there seem to be golden lines that appear to look like golden bracelets and golden anklets, as well as gold feathers on either side of her head for earrings. Tooth also has long, draping feathers that start at her waistline and end at her knees. They give the appearance of a skirt or dress.
Tooth first appeared when North used the Northern Lights to bring the Guardians together to talk about Pitch. When the Guardians are reunited, they don't believe that Pitch has returned until The Man in the Moon, with the help of Sandy, got their attention. The Man in the Moon told them that Pitch has returned and that he has chosen a new guardian: Jack Frost.
Tooth showed excitement when The Man in the Moon chose Jack, contrary to Bunnymund, who said that Jack doesn't care about children.
After successfully kidnapping Jack and bringing him to the North Pole, North introduces the other Guardians, and Tooth got excited to see Jack's teeth. When North started to explain why Jack was brought here, Tooth started to see Jack's teeth again and getting a warning from North to keep her finger out of his mouth. The Guardians told Jack that he was chosen as a Guardian and Jack refused. Causing a fight between Bunnymund and Jack and Sandy subjected for North to take Jack away.
As North explained to Jack about their center, Tooth noticed that her Palace was being attacked. So Tooth flew to her Palace to stop the Nightmares and Pitch from taking the teeth, but it was too late. On the way there, Jack rescued one of the fairies, Baby Tooth, and Tooth was happy to see her.
Pitch appeared, and Tooth threatened him to let her fairies go, resulting in Pitch asking her if she would put a quarter under his pillow. As Pitch started to mock the Guardians, Tooth took one of Bunnymund's boomerangs to try to attack Pitch before she was stopped by one of his Nightmares. The Guardians were shocked that Pitch was using Sandy's Dreamsand and attacked Pitch before he escaped.
Jack, curious, asked why Pitch took the teeth, and Tooth revealed that the teeth hold the greatest memories of childhood and why she collects the teeth. She also revealed that the Guardians were all somebody before they were chosen by the Man in the Moon, even Jack. Jack, surprised, asked her about his past life and his family, to which Tooth asked if he really doesn't remember anything and that she can't help him since Pitch has his memories.
North plans to collect the teeth to keep the children believing in Tooth. North asked Jack to help them collect the teeth, and in return, they would help him get his memories back, and Jack agrees to help them. The Guardians go around the world collecting teeth and making a competition of it. When Tooth told them they were as fast at collecting teeth and leaving gifts as her fairies, the guys remember that they forgot to leave a gift and had to travel back around the world to leave the gifts.
The Guardians gathered in Jamie's room but caused an uproar that caused Jamie and his dog, Abby, to wake up and see them (except Jack). Abby starts growling at Bunnymund, and Jamie tries to stop her. Jack wanting to have fun with Bunnymund, makes the alarm go off, causing Abby to attack Bunnymund and make him jump around the room. Sandy, trying to put Abby to sleep with his Dreamsand, ends up hitting everyone except Jack, Jamie, and himself. Jamie flies out of bed when North lands on it, and Sandy catches him. Sandman puts Jamie to sleep and then goes to fight Pitch's Nightmares that have appeared with the help of Jack.
North was able to wake up and bring Tooth and Bunnymund to help against Pitch. As the Guardians try to fight the nightmares, Pitch corner Sandy and stabs him with an arrow making the little guardian disappear. Jack, shocked to see what happened, attacked the Nightmares resulting in him using a massive wave that destroys them. Jack started to fall until Tooth caught him, and soon North used a globe to returned them to the Pole.
Back at the North Pole, the Guardians make a memorial for the Sandman. The Guardians decide to work hard for Easter to keep the children's belief in the Guardians. Bunnymund took them back to his Warren, and they soon found out that Jamie's sister, Sophie, was there. Tooth tries to impress her with some teeth that blood in them, making Sophie run away from her. Jack used a little magic to make Bunnymund have a little fun with Sophie while they finish the eggs.
Later, Jack took Sophie home, but once he left, the Warren was attacked by Nightmares resulting in Easter not happening. Jack found the Guardians and saw how the children stop believing in Bunnymund. They told him that the Nightmares attack the Warren, and the eggs didn't survive the confrontation. When Tooth asked about Baby Tooth and where he get the Tooth Box, Jack couldn't answer and ended up losing the Guardians' trust in him.
Toothiana later appeared when she and the Guardians try to find the last light, Jamie. She was surprised to see Jack have beat them to it, and as a result, Jamie has started to believe in him. Pitch appears, and Jack goes to fight him, causing the other Guardians to lead Jamie away. Pitch is more powerful than before, beats Jack, and makes him fall to the alley where the others were. Pitch traps the Guardians and Jamie; Jamie tells Jack that he's scared. Hearing that, Jack gets a memory of the same thing his sister once said, causing Jack to realize what his center is; Fun. Pitch approaches them but was hit by a snowball by Jack. Distracted, they escape and go gather up Jamie's friends.
With the help from the other Guardians, Jamie's friends started to believe again. Pitch asks them who was going to protect the Guardians if the Guardians were protecting them. Jack reassured Jamie to not be scared since the Nightmares are just bad dreams, and Jamie volunteered to protect the Guardians causing his friends to join him. As Pitch send the Nightmares their way, Jamie, full of confidence, was able to turn the black sand back to dream sand. Making the Guardians get their full strength back. The Guardians started to fight Pitch while Jamie and his friends turn the Nightmares back to dream sand.
The Guardians got Pitch cornered, but soon he disappeared and appeared behind a distracted Jack, but before he could injure him, Sandy was revived by Jamie and his friends and saved Jack. Sandy used his powers to bring sweet dreams to everyone, which resulted in more believers, and Tooth's fairies used the Tooth Box to bring memories to the children, making many of them believe.
The Guardians and the children started celebrating, and Jack hits Jamie with a snowball, which caused a friendly snowball fight. When Pitch woke up, he tried to make Jamie fear him again but found that Jamie was not scared of him anymore because he passed through him.
Pitch, afraid, retreats to his lair, which caused the Guardians to follow and confront him one last time. Tooth gave him a quarter before punching him, which resulted in teeth falling out. The Nightmares appear around them, and to their surprise, Pitch was taken away by his own Nightmare creatures. Tooth, happy about their success, hug Jack before Baby Tooth stopped her. North asked Jack about taking the oath, and the Guardian ceremony was performed again. Jack looked at Jamie, which caused him to nod. Proud of himself and of Jamie, Jack says, "I will," making him an official Guardian.
Jack makes his way toward North's sleigh, but he is stopped by Jamie calling his name. Jack turned around and is surprised by Jamie, who gave him a hug, which shocks Jack, but he eventually returns the hug. Jamie waves at Jack and The Guardians goodbye when they leave. Tooth smiled at Jack while he made his way back of the sleigh.
