Lockette

Lockette is the Pixie of Portals, she got herself lost, and is constantly on a journey to discover the secrets of her past throughout the series (or 'has many hidden passages in her heart'). Lockette not only helps Bloom find her way physically, but also emotionally, as she tries to discover her true self and connect with her power and family. Lockette's guidance and loyalty saves Bloom on many an occasions, and the two are inseparable (much to Kiko's dismay). Also in Season 3 it seems that she doesn't like Prince Sky that much. It has not been confirmed whether or not she and the other pixies will return in Season 5.
