"Amulet Angel's" only useful moves are "White Flag", "White Flag Double Plan", and "Angel Wink". (Even though her abilities are reduced by not being with her own owner, Utau.) By being super-cute and innocent, she can attract alot of boys.
In Episode 35 of the anime, Amulet Angel once attempted to use a power named "Love Repair Beam" to restore two lovers' passion, but failed because the passion was never gone to begin with.

Guardian Characters

Unlike normal children, who usually have only one guardian character (or, on some cases, two), Amu is gifted with three, and eventually, a fourth one is born. Their theme centers around the four suits in a card deck: heart, spade, clover, and diamond.
The word "Amulet" means good luck as it was said in Episode 1 of Shugo Chara Party!

Ran is the first guardian character to hatch, and the first to character transform with Amu. She is extremely energetic and is almost never seen without her cheerleader pom-poms. She is born from Amu's wish to become someone other than herself.
Ran represents Amu's desire to be more honest, athletic, and confident.
Likes: Cheering on other people
Hates: Keeping still

Miki is the second guardian character to hatch. She is very artistic and fashionable. Her powers include increasing Amu's drawing and painting abilities. She is born from Amu's wish to become someone other than herself. In Shugo Chara! Doki, Miki is the only one out of Amu's Guardian Characters to be able to sense Mystery Eggs clearly. Miki is also the guardian character that reflects on Amu's love interests, she shows an interest in Tadase's, Ikuto's, Kukai's, Nagihiko's, and Kairi's Guardian Characters.
Miki represents Amu's desire to be more sharp, levelheaded and artistic.

Su is the third guardian character to hatch. She tends to be very girly and doesn't have many fighting skills, but has domestic skills. She is very good at housekeeping, cooking, and knitting. She is born from Amu's wish to become someone other than herself.
Suu represents Amu's desire to be more caring, sensitive, and improve her domestic skills.
Likes: Cleaning and Cooking
Hates: Caterpillars

Dia is Amu's fourth and final Guardian Character. Her egg was created a while after Ran, Miki, and Suu were born. Because Amu disliked everything that happened in the spring term, Dia lost sight of her owner, became an X-Character, and went to Hoshina Utau. She returned to her slumber after Amu "shines again," but came out permanently later. She's positive and wise, yet something of an air-head. Dia will be staying out of her egg for the latest chapters, looking for Amu's three other eggs that disapeared. At the end of shugo chara encore chapter 4 Dia rehatches.
In Chapter 38, Dia comes back when Amu "shines" and undergoes a new Character Transformation with Ran, Miki, and Suu, becoming Amulet Fortune.
Dia represents Amu's desire to be an idol, be noticed in front of others, and shine.
Likes: People who sparkle
Dislikes: People who are sad

Humpty Lock

According to the Founding King's legend, a person with three Guardian Characters will have very special powers and will be given the Humpty lock to be able to harness those powers. It was this item that granted her the ability to Character Transform, as well as granting the other Guardians this ability later. The Humpty Lock has strong reactions to her emotions.
She can also use it to activate her finishing move: Open Heart, to cleanse X-Eggs and X-Characters and free their owners from despair and negativity.
Humpty Lock is Amu's main weapon and is a counterpart to Dumpty Key, which can create very powerful phenomenon when both are brought together.

Iru

Utau's first Guardian Character that is seen is the conflict-loving, devilish girl, Il. She dislikes peace and becomes very bored if the current situation is peaceful. She tells El at one point that a Guardian Character that doesn't even Character Transforms is not needed. Soon after, El left Utau, and ll actually became so bored that she wanted Eru to return so she can tease her. She also tends to be very rude to others, in particular to Yukari Sanjo. This was shown when she called her a old woman when she's actually in her 20s. Her and El's names are usually pronounced "Iru" and "Eru". The name "Il" is also the last two letters of the word DEVIL.

Eru

Utau's second guardian character is the angel-like El. Although El is pure hearted, she can be very hyper and sometimes acts over the top, or becoming really annoying, declaring herself as the "angel of love". She hates it when others (especially the Guardians) talk about love when she's not there. She also has a habit of singing. It is shown that El might have a crush on Rhythm when he hugged her. She left Utau because of the continuous teasing of Il and also Utau was ignoring her. Then she decided to stay with Amu. Ran was taking care of her when Amu is not home. El is shown to miss Utau soon though, and she eventually returns to Utau after the 'X' on Dia was lifted. El's name, like Il, is the last two letters of what she is like, ANGEL.

Kiseki
Tadase's Guardian Character is Kiseki, who was born from his desire to become stronger and the dream of world domination. Also, Kiseki acts as if he is the leader amongst all the Guardian Characters. It's a running gag for the other Guardian Characters to ignore him. Kiseki has light purple hair and blue eyes. He has been described as "a mini-Tadase" by Amu. He wears a king's outfit with puffy dark blue pants with white strpies, and a long red cape with a yellow crown. His outfit is like the King of France or what the royal king wore in the French Revolution.

Temari

Nadeshiko's first Guardian Character is the elegant, yet fierce-tempered Temari. Prior to Nadeshiko's return from Europe, she went back to her egg to slumber for a long period of time. During the final confrontation against Easter, her owner is reminded of all the problems of being a girl and his passion for dancing. When he is able to overcome those problems, Temari is finally able to reawaken from her sleep.Later during Episode 109 Amu sees a poster with Nadeshiko on it. So she goes to the spot where Nadeshiko is planning to perform.Then Nadehiko runs to the dressing room and switch to Nadeshiko and Rhythm switchs with Temari


Rythm

While Nagihiko was in Europe, he dropped the confidence of dancing like a girl and Temari was forced back into her egg, at the same time, Rhythm's egg was born, which he later brings with him back to Japan. When Nagihiko remembers how much he loves basketball in his own rhythm, it hatches into the cool and outgoing, Rhythm. Although Rhythm makes Nagihiko do some embarrassing things, Nagihiko still loves him.


Kusu-Kusu

Rima's Guardian Character is the comedic Kusukusu, who is born from her desire to make others laugh.
Whenever Rima feels sad, she would make funny faces to cheer her up. Like Rima, they share a passion for making perfect funny performance to make others laugh.
 

Daichi

Kukai's Guardian Character is Daichi, born from his passion for sports but was indecisive to choose one to stick with. He appears to be best friends with Rhythm. Ran and Daichi have somewhat of a close relationship , both being Guardian Characters of sports. In episode 91 Ran and Daichi were on the same team playing basketball against the other Guardian Characters (Su, Kiseki etc.)



Musashi
Kairi's Guardian Character is the samurai Musashi, created from his will to be a strong samurai and protect the weak. As a headstrong character, Musashi is very wise and calm and deep-voiced.


Pepe

Yaya Guardian Character is the infant-like Pepe, born from her desire to become a baby again. Pepe has darkish orange hair in two ponytails like Yaya and light blue eyes.

Synopsis 
Amu Hinamori is a student at Seiyo Elementary, where she has a reputation for being "cool and spicy"; however, her real personality is that of an extremely shy and easily intimidated girl. One night Amu makes a wish that she would have the courage to be reborn as her "would-be" self. The next morning Amu finds three brightly colored eggs—red, blue, and green—in her bed. Each egg eventually hatches into a Guardian Character: Ran, Miki, and Su. Guardian Characters are angel-like beings that aid a person into becoming their "would-be" selves and fulfill the person's dreams. The Guardian Characters accomplish this by giving encouragement and advice, but they can also temporarily change a person's personality and abilities. With the Guardian Characters, Amu's life becomes much more complex as she now struggles to deal with her new personalities and the Seiyo Elementary Guardians—a student council group where each member has their own Guardian Character—who recruits Amu to search for and seal the X eggs and X Characters, corrupted forms of people's dreams.
