Hattori is the mother of the twins: Ember, Dusk, and Diana, making herself a member of the Drama Family. After she and her husband, Koji, went through Ember's birth, she abandoned her and isolated herself for a long time, away from the family.

​

After learning about Dusk's passing, she decided to return to the family, forcing her involvement with the current war. Sometime during her isolation, she became a cyborg, which she used to aid her in battle. One aspect of this new physiology is that she had the brain and knowledge like a computer. With the abundence of knowledge bestowing herself, she reprogrammed Seven to personally partner up as a duo.

​

After learning about Ember's passing, she went on a vengeful rampage, assaulting non-antagonistic individuals. This was shortly lived, however, as she realized there was a chance to bring her daughter back to life. During the mission, she stumbled across an old aquaintance, her husband, Koji. An awkward reunion, however, as he decided not to help out, leaving her like she had.

​

Hattori figured out a way to getting her daughter back: by penetrating spacetime, creating a doorway to enter Heaven. She found many thugs lurking around in this dimension. Nearing the end of the fight against SpongeBob, she discovers that Ember is being held captive by the Galactic Federation. After getting defeated by SpongeBob, her next move was one that would fear the universe, and including himself... getting back up. SpongeBob would then contact the Galactice Federation to stop her. Underestimating Hattori, the Feds would send in their subordinate leader, who would fail to stop her. Knowing it was time to send in someone with great strenght, he clicked on the POD button next to the prisoner's cell. Hattori's daughter would come out and successfully defeat her, left with an unknown fate.
