Tiny [[fairy|fairies]] born from the "egg" of a child's heart in [[Shugo Chara!]], also known as the "[[Heart's Egg (shugo chara!)|]]". Sometimes, a strong emotion can trigger the egg to hatch into a Guardian Chara in order to aid that person in becoming his or her would-be self and pursue his or her dreams. If the egg gets corrupted, it may turn into an [[X-Egg (shugo chara!)|]].

These creatures are invisible to normal people, and only owners of Guardian Charas and pure-hearted children can see them.

When owners of Guardian Charas character transform with them, they turn into their "would-be-selves."
