Vidia is the daughter of Queen Clarion and her true love, Joseph. She was born in Pixie Hollow, Clarion's favourite daughter, and often outshone her elder sister, Fiona.
When all is said and done, Vidia is sly, grouchy, vindictive, and narcissistic, but has a good heart. She tends to use sugary phrases such as "darling" and "dear" in a condescending manner to other fairies. She is said to be the fastest fairy in Pixie Hollow, but her title gets to her head, as she is determined to keep her title and would go to great lengths to achieve this. Not only does she feel she is the best in speed, but the best fairy overall and berates anyone who thinks otherwise. She is incredibly strong-willed and outspoken, much like Tinker Bell, which can also indicate why the two fairies clash many times.
Despite her negative traits, Vidia ultimately has a good heart, most notably seen in Tinker Bell and the Great Fairy Rescue where she follows after Tinker Bell to ensure she stays out of trouble and traps her in a fairy-sized house made by a human girl in an attempt to teach Tink a good lesson on how dangerous human things can be. When the human girl ends up taking Tink to her home, Vidia puts all of her differences and animosity with the tinker aside to rescue her, feeling responsible. Upon this adventure, Vidia reforms completely and is shown to be much friendlier with Tink and her friends.
Even so, she still maintains her anti-hero persona as seen in The Pixie Hollow Games where she is looking forward to Rosetta embarrassing herself during the competitions, knowing the garden fairy's fear of dirt and mud (which is much unlike the other garden fairies, who only do not want to enter because they never even came close to winning). She still holds her low opinion of tinkers when she, Tinker Bell, and Silvermist switch talents, with her becoming a tinker, much to her horror (though she soon grows to accept and warm up to it).
