In this form, the powers of a fairy are very stronger, acquire the ability to be miniaturized and can break dark spells with fairy dust, which is contained inside a collar.
Fairies not always has to go to their respective planets to get their Enchantix, this was seen when Stella protected her father from a dragon in Eraklyon. Musa when she saved the Princess Galatea from a fire in Alfea and Tecna when she closed the portal of the Omega Dimension, located in the kingdom of Andros, but whose instability was a danger to the whole magical dimension, including her home planet Zenith.
Bloom was the exception to the rule. By believing in her power to overcome evil, learn to focus her energy with the sorceress Mya on Pyros and put aside the desire for revenge and anger that she was carrying. Bloom could transform by herself through force of will, also thanks that she found Buddy, her inner dragon.
