Years ago, an beautiful woman named Saldana was known as the Mistress of Sorcery combined with ninjutsu. She was friends with her partner named Master Splinter and the two became friends. Later on, she was married to a handsome ninja and the two gave birth to a newborn son. When the Shredder came by, Saldana used her magic to battle him, causing Shredder to kill her husband and her son. After moving to New York City, Saldana had just gave birth to four girls who somehow possesses the same chi magic powers as hers. From that moment on, Saldana used her magic to create invisible Flying Fortress and lived there to take care of her daughters from the outside world.

Saldana has watched her eldest daughter practicing her chi magic of ice and water. She had named her Leona (or Lee for short). Lee is the most serious and focused of the sisters who is also a big fan of science-fiction and loves to watch her favorite series Space Heroes. She loves her favorite character Captain Ryan and has a habit of memorizing Captain Ryan's best lines from the show and repeating them. Only thing Saldana saw through her most mature and responsible daughter was being as childish as her sisters, such as trying to be like an unrealistic TV character. But Lee often tries to comfort her sisters when they are scared or upset. Saldana admires Lee when she comes up with most of the plans and strategies while she and her sisters are training.

Saldana has watched her second eldest daughter practicing her chi magic of earth and fire. She had named her Rafaela (or Ella for short). Ella has a short temper that she is known for with her tough, fearless attitude who is quick-to-act and prefers to hit first and ask questions later. While she loves her sisters fiercely, she is the first to give them a hard time and is constantly questioning Lee's leadership, Donna's intelligence and Ella's slow-wittedness. Saldana knows Ella's relationship with Lee does not involve a lot of fighting but trust and care. With Ellie, she insults her but she cares for her. And her relationship with Donna involves threats, glares, hitting, insulting, and bullying. Saldana describes Ella as her strongest daughter, who often acts before she thinks. But she also has a pet parasitic cat named Samson, which she had secretly confides in during major points of her life. Some of the time, Saldana watches Ella slaps or threatens to slap her sisters for their own good. Saldana admires Ella when she is an all-out bully hero with an caring side.

Saldana has watched her second youngest daughter practicing her chi magic of plant and technology. She had named her Donnatella (or Donna for short). Donna is extremely intelligent and technical who always working on a strategy whether building machines. She talks a lot in order to describe or explain a situation or theory in full, even when in the face of situation. She is also more short-tempered, getting frustrated easily and shouting when angry which Saldana finds it unusual to her. Saldana admires Donna being more active and purpose-driven, but at times does not understand and/or has a hard time grasping her lectures.

Saldana has watched her youngest daughter practicing her chi magic of light and music. She had named her Michelle (or Ellie for short). Ellie is least mature of her sisters who is very enthusiastic, positive and adaptable with an strong creativity and goes with the flow. She loves pop culture and yearns to be a part of the real world as she insists that people will accept her and her sisters as equals if given the chance. Saldana describes Ellie as her most impulsive daughter, naturally gifted and having more raw talent than her sisters combined, but she wishes Ellie would focus more on her training. She is shown to be scatterbrained and somewhat dim-witted, sometimes causing problems for the team because of this. Sometimes, her sisters might see she can be intelligent sometimes. It is also shown that she is most close to Donnatella and she is highly protected by her sisters.

Together, Leona, Rafaela, Donnatella, and Michelle will band together and survive anything.

Or so it seems.
