- “[A] few key Sunnydale alum have been tracking down the recently chosen... uh, guiding them, training them... giving them the full X-Men, minus the crappy third act.”

The Slayer Organization was an institution founded by the Scooby Gang to gather and train the newly-activated Slayers following the Battle at the Hellmouth. It included approximately five hundred Slayers split across ten separate squads, as well as mystics, watchers, and other vampire hunters.
The Slayer Organization was founded in the aftermath of the Battle at the Hellmouth, during which Willow Rosenberg used the power of the Scythe to activate every Potential Slayer across the world. Following their victory at the Hellmouth and the destruction of Sunnydale, she and her friends spread out around the world to locate and train the Slayers they were now responsible for.
Newly located Slayers were not forced to join the Organization if they don’t want to, but are nonetheless told the score about Slayers and vampires. An implicit Slayer Organization commercial was made in order to recruit the ever-growing number of Slayers worldwide activated for the Organization.
After Buffy broke the Seed of Wonder and brought the End of magic, there was a loss of faith in her leadership and the Organization disbanded. Some Slayers would become part of the newly founded security agency Deepscan, others continued to patrol and slay, and some even rejected the Slayer title.
Due to the Watchers Council’s destruction, the only known traditionally trained watcher was Rupert Giles, but Xander Harris, Andrew Wells, and Robin Wood were also de facto watchers. Still, for the first time Slayers outnumbered their watchers.
