User blog comment:CoolJazzman/Grimmjow "new Fraccion"?/@comment-893506-20130604162546

Additionally, like Harribel, Grimmjow's Fracción began to follow him as Hollows, before they even met Aizen. Like Kuro said, the "Fracción" system was developed by Aizen, but even with subordinates... Grimmjow's highly unlikely to have other Hollows or Arrancar follow him. His Shawlong, Edrad, Nakeem, Yylfordt, and Di Roy were the only ones he ever got along with.
