that is an interpretation of the classic cyberpunk Character from Gibson's Sprawl Trilogy, Molly Millions. Now Molly Millions is everything a Cyberpunk anti-heroine should be, She's got a punk attitude, she's a cyborg and a mercenary who has steel razor claws that can retract into her fingers.
Now I can see why after that people would call Ghost in the shell Cyberpunk. Now they have it half right. Ghost in the Shell is Cyber, however to be a cyberpunk work, you need to have both parts of that fulfilled and Ghost in the Shell doesn't have the chops to fulfill the punk part (oh yeah, I also don't like Anime or Manga and think 95 percent of it is overrated)
But now the major may be a cyborg badass but there is another part of her character that essentially means the whole series cannot be described as Cyberpunk.
The Major is well, a government employee, she's the symbol of oppression, she's well working for the man doing what the man wants.
The very fact of the kinds of things she does for the government as a protagonist means this is not a work of Cyberpunk, sure a character like her can be in a work of cyberpunk, but not as the protagonist and certainly not as any kind of hero anti or otherwise. She'd have to be the Antagonist and the Villain. She's the kind of person the hacker, or the private investigator would be hunted by and have to kill in order to accomplish their mission.
So that is just one reason and one very large one, why Ghost in the Shell is not in the Cyberpunk Genre despite being saying it is when they have no clue what cyberpunk actually means.
