When Brenda was born, her father, Diablo Wagner, made infant formula that was intended to kill her because he hates his nice family, especially his wife, Karen Wagner. Halley Wagner (who was 11 years old at the time) switched the poison out for a friendlier option, pixie dust, which instead made her into a fairy. Her father was shocked by the fact that Halley switched the poison, that he swapped her mother's gender to male, and removed her memories of her daughters, and the Wagners forever. When Brenda was 2, she talked in complete sentences, which shocked Halley Wagner. When she was 5, she painted her first picture, which features multicolored flowers in the summer breeze. She hung the picture up in her room. One day, when she was 7, she used her magical powers to pretend that she is a cat, then she transformed into a cat, and it becomes her main animal form.
She is very imaginative, probably whimsical, mildly zany, and very vivid. She is also pretty creative, sometimes feisty, very spunky and has lots of charisma. She is very loyal and trustworthy to her sister... sometimes. She is also a fun-loving girl who will never let anyone down when they are sad, even for her older sister. She is also very sweet, very delightful, and pretty charming. She is also a quirky and versatile kid. Plus, she is also multi-talented and sort of smart. She loves magic as she is a half-fairy, half-human, and is quite the pro at it. She loves to paint flowers, stars and her older sister in comedic ways. She also loves to pretend she's different animals and people. She also loves to do many types of puzzles with Reena Raccoon and her late friend, Debbie Sherman. Her friends are Melissa McMary, Brock Maviner, and Nathaniel Caesar.
