Warren Nichols (Brother)
Stevie first appeared in "Detention Election ". While she is in detention, Stevie meets Alex. They soon became friends and learn they have a lot in common, like for example, they both like to cause trouble after "Dentention Election" Alex and Harper discovers Stevie is a wizard and soon Harper feels like the third wheel (read more in the second and third paragraph for more information).
In "Eat to the Beat", when Alex and Justin are fighting, Stevie uses a spell to turn a rock band into a smooth jazz band. Harper, who saw Stevie use magic, attempts to tell Alex. However, Stevie is able to stop her by using a spell to erase Harper's memory of what she saw.
Harper is able to regain her memory of the event in the lunchroom, and informs Alex that Stevie is a wizard. Soon after, Alex and Stevie went onto magical adventures leaving Harper behind.
In "The Good, The Bad and the Alex", Stevie conducts a revolution of wizards to override the power distributor, which is what takes wizards' powers away and transfers them when they lose the wizard competition, and gets Alex and Max to join her. However, she was unaware that Alex would turn on her. Alex and Harper help Warren get his full powers by transferring Stevie's powers to him, while Stevie is frozen. Not much after, Max accidentally tipped over Stevie's statue, shattering her body.
She was later put back together and restored to life, then sent to an island in the Wizard World.
Stevie's personality is very similar to Alex being rebellious, impulsive and loves to cause trouble. However, Stevie seems to not possess the same compassion and kind-heartedness that Alex does as it shows that it is actually an evil person only reoccupy itself.
Stevie demonstrates a good handle on using spells and like Alex is good to improvise. However, her powers are not as good as his brother having lost with him in the family competence.
She is currently a mortal due to her loss of magical powers.
