Kojoji Kazeki

Kojoji Kazeki
Or just shortened to "Koji" by his fellow Arrancar, was the first Vasto Lorde. 2000 Years before the current storyline, the Gotei 50, (Now the Gotei 13 before the Hollow Massacre 1500 years ago to the current storyline.) tried to hunt him down due to his extreme power and potential to take over Hueco Mundo, But failed (The Gotei 50.) at least 15 times.

Kojoji began to realize his potential, and considered taking over Hueco Mundo as hollow king, Since no other Hollow or Arrancar considered challenging him, but was defeated by Barragan Luisenbarn (In his younger years.) and Barragan became king for 2000 years.

Kojoji then started a "Power hunt" by killing every Arrancar he saw. (Since arrancar then were extremely rare and the most powerful force in Hueco Mundo, with the exeption of Barragan Luisenbarn.) He then stumbled across a child Coyote Stark in his single form. (This was before Stark created Lilinette.) Kojoji Attempted to kill him as well, but met his untimely demise at Stark's hands.
