A character transformation (キャラなり, literally charanari) is a special ability in the manga and anime series Shugo Chara!.
A character transformation simply sees someone combining powers with his or her Guardian character. The character goes into his or her egg, which then goes into the owner's heart. This ability surpasses the power of a Character Change by 120% of its normal power. This ability is rare, so there aren't many who can transform. The Humpty Lock and the Dumpty Key allow their owners to transform at will, though, as well as others who are near. During a transformation, the owner can use various magical abilities powered by the character. The character is still active, for he or she can still communicate and can force the owner to do some actions unwillingly. It is possible for the owner to switch transformations if he or she owns more than one character. It is possible to transform with other people's Guardian characters, (most likely with the power of the Humpty Lock or the Dumpty Key); however the power is not at its best and the transformation will last shorter and consume one's energy faster.
With the Humpty Lock's, Character Transformations are a staple for Amu in her quest to purify X-Eggs and X-Characters. She first learns to transform with Ran and become the athletic "Amulet Heart"; later with Miki to become the level-headed artist, "Amulet Spade"; later, she also learns to transform with Su and become the domestic "Amulet Clover" who can repair any damaged object.
Aside from her own Guardian Characters, Amu has also transformed before with Il and El into "Amulet Devil" and "Amulet Angel", respectively when they both opposed their master, Utau. Amu, Ran, Miki, Su, and Dia combined powers at one point to transform into "Amulet Fortune", but this was only a temporary transformation.
The Dumpty Key allows Ikuto to Character Transform with Yoru into "Black Lynx". The influence of a black egg turned him into "Death Rebel" for a time being, and when transforming with both, he becomes "Seven Seas Treasure", but this was only temporary.
In the second season of the anime, the new Easter worker Lulu De Morcerf uses a ruby necklace to help ordinary people character transform by turning their Heart's Eggs into Mystery Eggs. Should that person become provoked, he or she will character transform into a powerful character.
