Quote1 Yes, Just as betrayal is what I do. Cruel Luka, Dealer in homocide. Sororicide. You were no father to me. You were a scientist, blinded to the damage you inflicted on your experiments. But now I will step over your stolen body and take my rightful place in the center of the web. Tell me. "Father," How does it feel to be the helpless one for once? Quote2

Katrina "Luka" Netz[1][2], known as Katherine "Kathy" Webb-Kane, is the daughter of Otto Netz and the first Batwoman. Raised to be his successor, she becomes the Headmistress of Spyral and acts as an operative within the Espionage community.[3] Later, she takes up her father's old codename and becomes Agent Zero, remaining a secret member of both Spyral and Leviathan.[4]



Born to Otto Netz and a sibling of Elisabeth, their father would often read to them various poems of his interest. He also groomed them to be in his own image, foretelling them of his ailing condition, his Spyder program, and their destiny to one day for them to be used as a vessel of his body as Agent Zero while the other will challenge him as the leader of Leviathan. Often enough, the sisters would share a turbulent relationship with one another, often fighting with their father encouraging them.[5]

As BatwomanEdit

As Agent ZeroEdit

  • Hypnos 2.0: Luka possesses Hypnos in which allows her to disappear from individual's memory after meeting them, create disguises, and is capable of attacking other's mind. While posessing it, those who look into her face see a spiral and can only be removed via will or remote de-encrypted from another user of Hypnos.[8]
  • Raincoat: Luka's raincoat, in which has a yellow/red color scheme similar to her Batwoman costume, houses some of her gadgets (most likely from her stint as Bawoman). Those include:
  • Modified Smartphone: This modifided smartphone is connected to her known base of location: the Eternal Circle. She can control the security system remotely via the phone.
  • Dart Lipstick
  • Gun

To further cover up her trail, Luka has a program within the Eternal Circle in which scours the net for images in which feature her anywhere and deletes them off the net .[12]


  • This page covers both information of New Earth as well as Prime Earth's Katherine Webb (Kathy Kane), in which a retcon changed her birth name to Katrina "Luka" Netz most likely to deviate confusion from the current Batwoman's name, Kate Kane.
  • According to Tim Seeley, the reason why Dick Grayson did not recognize Katrina as the first Batwoman was because of Flashpoint making him forget.[13]


  • Tim Seeley himself confirmed the connection between Kathy Kane and Luka in which was heavily hinted.[14]
