The writer of the recently-announced reboot of Buffy the Vampire Slayer took to Twitter on Thursday to answer back to grumbling she's replacing Sarah Michelle Gellar in the iconic role.

Monica Owusu-Breen - who penned the pilot in the Joss Whedon-produced reboot - made clear she's in reverence of the series, as she's tapped a black actress to commandeer the titular role.

'For some genre writers it's Star Wars. Buffy the Vampire Slayer is my Star Wars,' Owusu-Breen said in a Tweet Thursday. 'Before I became a writer, I was a fan. For seven seasons I watched Buffy Summers grow up, find love, kill that love. I watched her fight, and struggle and slay.'

Owusu-Breen, who has credits on shows such as Midnight, Texas, Agents of S.H.I.E.L.D. and Lost, rattled off the names of the characters on the series, which ran from 1997-2003 on networks including The WB and UPN.

'There is only one Buffy,' she wrote. 'One Xander, one Willow, Giles, Cordelia, Oz, Tara, Kendra, Faith, Spike, Angel…They can't be replaced.'

Owusu-Breen said that 'Whedon's brilliant and beautiful series can't be replicated,' and that she 'wouldn't try to.

'But here we are, twenty years later…And the world seems a lot scarier. So maybe, it could be time to meet a new Slayer…And that's all I can say,' she said.

Last week news broke of the reboot, according to The Hollywood Reporter, with 20th Century Fox Television developing the show with no network attached yet; a bidding war is expected for what was one of the most successful and popular shows TV shows of all time.

The show was based on a 1992 comedy horror film of the same name written by Whedon, starring Donald Sutherland, Paul Reubens, Rutger Hauer, Luke Perry, David Arquette and Hilary Swank, with Kristy Swanson playing the protagonist.

Whedon wasn't happy with the direction the film went, and five years later, introduced the acclaimed TV series of the same name. The premise follows the teenage Buffy, the latest in a line of Slayers, whose job it is to battle vampires, demons, and monsters that slip through the hellmouth portal, on top of which her high-school happens to be built upon.

It starred - and also launched the careers of - the likes of Alyson Hannigan, Seth Green, David Boreanaz, Charisma Carpenter and James Marsters.

The show ran for seven seasons and 145 episodes, and spawned a wide-ranging expanded 'Buffyverse' of games, novels, and comics, as well as the spin-off show Angel.
