History
In the Magical Forest, Drizella is born with magic. As a child, Drizella had a strong bond with her sister, promising to always be there for one another. After her mother's disappearance, Drizella gives up hope that her mother would ever return. When her father marries Cecelia, she warms up to her as a motherly figure. When Rapunzel returns, Drizella acts cold towards her and acknowledges Cecelia as her mother, prompting Rapunzel to curse Cecelia.
One day, she is called upon, by Lady Tremaine, who reveals to her the Fairy Godmother of Cinderella. Drizella is told by Lady Tremaine that magic does not make one powerful as it can be taken away, instead, one needs to inflict fear. Making an exception, Lady Tremaine uses the Fairy Godmother's wand and kills her in front of Drizella before they both head for a ball. At the ball, she is rejected by the prince, causing her mother to set her sights on pairing her with the prince's brother, who has taken a liking to Drizella. When Cinderella is falsely accused of assassinating the prince, Drizella witnesses a stranger aid in her stepsister's escape.

After Lady Tremaine successfully captures the stranger and holds him captive in Cinderella's bedroom, she prepares to leave to continue searching for her stepdaughter, but not before directing Drizella to force Henry into revealing where he hid Cinderella's slipper and then kill him. Drizella states that she doesn't understand why this is necessary, but Lady Tremaine tells her that she does not need to understand, just obey. Henry attempts to plead with Drizella, noting that she seems kinder than her mother, but Drizella smirks, pulls out a dagger, and assures him that she is not. Before she can interrogate him fully, Regina and Hook burst through a portal, defeating the knights guarding the door and demanding that Drizella set Henry free. Drizella is shocked and questions who they are and Regina responds that she is Henry's mother before magically knocking Drizella into a wall, rendering her unconscious.
Hoping to free herself from her mother's grip, Drizella sneaks away to an abandoned tower to find magic and briefly trains with Regina. Acquiring better skills, she confronts her mother with Prince Gregor by her side and kills him in front of her to reveal that she turned her heart dark to prevent her mother from using her heart to revive her deceased sister.
With help from the Coven of the Eight, Drizella and Gothel abduct Henry and poison him in order to get Regina to cast the Dark Curse. When it's cast, Drizella, along with the other inhabitants of the Magical Forest, is sent to the Land Without Magic.

Drizella's cursed counterpart, Ivy Belfrey.
In Hyperion Heights, she is known as Ivy Belfrey, an assistant to her mother at Belfrey Towers. When Jacinda tries to escape the city with Lucy, her mother, Victoria, sends her and Officer Rogers to find Lucy. Once locating Lucy, Ivy confiscates Lucy's Once Upon a Time book and hands it over to Officer Rogers as the book causes much trouble. Ivy later teams up with Henry to get dirt on her mother but ends up with a suspicious Roni who believes Ivy is tricking Henry. They both head to the highest floor of Belfrey Towers and Roni finds a photograph. It's revealed that Drizella is not actually cursed and is fully aware of who she is. She is working with the Gothel and tricking her mother, Henry, and Roni into trusting her to further their unknown plan. Ivy later makes the Witch create a potion which is used on Roni, waking her up from her cursed self and forces her to prevent Henry and Jacinda from getting together. She witnesses her mother awaken Anastasia using Lucy's tear. Upon obtaining Anastasia, Gothel double-crosses Ivy and pushes her down the well where Victoria is. When Gothel plans to sacrifice Ivy in order to heal Lucy with a resurrection amulet, Victoria takes her place instead. When her mother sacrifices herself to save her, Ivy began to realize the wrongdoings of her ways and make amends with Henry, Jacinda, and Roni. She then saves Anastasia from Eloise and Mr. Samdi. After making amends, Ivy and Anastasia use a magic bean to return to the Magical Forest.
