She is the biological daughter of Peter Hale and Corinne, The Desert Wolf. Malia was born on November 28 at Midtown Memorial Hospital.
Knowing that Corrine would kill her, Talia Hale had her put up for adoption right after birth. She was officially adopted less than a month later by Evelyn and Henry Tate and never knew of her true lineage.
When she was nine years old, Corrine shot at a car Malia, Evelyn and Kiley, the younger sibling, were riding in. Prior to this, she and Evelyn had been fighting which Malia had wished she was dead. The crashed had caused Malia to transform and kill her family in an uncontrolled state. She carried tremendous guilt about the incident and remained a full coyote and lived near the crash site.
Malia still remembered her past and kept many of her human belongings and developed a sentimental attachment to her younger sister's doll.
She was thought dead for eight years until Scott McCall and Stiles Stilinski stumbled upon her den. Scott forced her to return to human form and was unable to change back. She was committed to Eichen House, a mental institution for a brief time after reuniting with her adoptive father.
After helping Stiles in Eichen and forming a connection with him as a mate, she sought out Scott to harness her shapeshifting abilities while Stiles helped her reintegrate into human society and think less like a coyote.
Having learned that Peter Hale is her father, she worked with him to find her birth mother until she saw him as the monster he really was. They eventually reconciled during the events of Ghost Riders when he began to risk his life to protect her.
She found her mother with the help of Braeden and learned of Corrine's involvement in her family's car crash. Corrine had attempted to kill her to regain her lost power, but Malia turned the tables on her with genetically enhanced talons that siphoned the rest of Corrine's power.
After defeating her mother, Malia regained the ability to shift into a full coyote but continued to struggle with controlling her shift due to the Ghost Riders removing the memories of her anchor, Stiles. Once her father returns from the Wild Hunt, Malia begins to repair her familial relationship with Peter. She later forms a romantic relationship with Scott in the midst of the battle with Tamora Monroe and her Hunters.
