We know that Kubo created the character and setting, but there is no proof that he wrote the script for that story or if the anime stuck to it if he did write it. It cannot be considered canon. Canon mentions of Vasto Lorde are:


 * 1) Hitsugaya's lecture: Human-sized
 * 2) Aizen & Gin talking about gathering them & perfecting the Espada
 * 3) Uryu upon arriving in Hueco Mundo mentions that Urahara told him that Vasto Lordes were the only Hollows guaranteed to take on Human form when they are Arrancarized (suggesting that they are not completely humanoid in their natural state)
 * 4) Grimmjow's flashback about trying to become one
 * 5) Nelliel & Nnoitra searching for them in flashback
