She is played by Barbie Roberts and voiced by Kelly Sheridan.

What Makes Her Pure Good?[]

Though she appears as a shy and quiet person, she later subverts these qualities by gaining confidence at the end.
Apologizes to Mr. Primrose for accidentally injuring his leg when she is trying to practice her dance for the royal ball. In addition, she immediately helps him up to give him a rest.
She takes her grandmother's words: "You'll never know what you can do unless you try", which later helps her have all confidence to defeat Malucia.
Upon arriving at Zinnia, she befriends Nori and Romy even after they attacks her when they first meet as they think she may be a threat.
She befriends all the fairies, mermaids and unicorns.
Discovering that she has magic and that Princess Malucia has stolen the magic of every creature she captures, Alexa decides to strengthen her magical power, intending to returned all fairy wings and mermaid tails to them.
She tries to use magic on Nori and Romy to turn them back into a fairy and a mermaid, but fails because their magic is still in Malucia's scepter.
Learning that Malucia has finally known where the Queen Unicorn (who is the most magical creature in Zinnia) is hiding, she, Nori and Romy travel to save her, only to unintentionally lead Malucia and her minions right to her.
Even though Nori and Romy provide a distraction so that she can escape to her world, Alexa decides to stay and help her friends, knowing that they need her.
She and the girls go to Malucia's castle to try and rescue the Queen Unicorn and other unicorns the evil princess captures.
She confronts Malucia, declaring that she is a princess, too, which provokes Malucia into a magical battle to "prove" who is the better princess.
When she realizes that Malucia's scepter is cracking under its magical content, she pretends to surrender for Malucia to steal all her magic, which causes Malucia's scepter to explode, releasing all its magic.
After Malucia is defeated, Alexa returns all the magic to their rightful owners, including Nori, Romy and the Queen Unicorn.
Before returning to her kingdom, she says goodbye to her new friends and promises to visit them soon.
When returning to the palace, Alexa decides to greet Prince Kieran after her completed speech to everyone.
