Vhisola

Vhisola was a Ga-Matoran.

Metru Nui
On Metru Nui, Vhisola was one of the six Matoran that knew the location of a Great Disk. She was a student of Nokama in Ga-Metru, and considered the future Toa to be her best friend. She tended to be possessive of her teacher, being jealous of Nokama´s other friends. When Nokama was transformed into a Toa Metru, Vhisola became even more jealous and resentful, thinking that Nokama would be too busy to care about her, and planned to use her knowledge of the location of the Ga-Metru´s Great Disk to become more famous than her friend. But this attracted the attention of the Dark Hunters Nidhiki and Krekka, who had been hired by Makuta Teridax to help him take over the city. They used Ahkmou, a treacherous Po-Matoran, to try to trap Vhisola and get the Disk, but Nokama saved her. Vhisola told the Toa where to find the Great Disk, and also shared her theory that the Disks might help to destroy the Morbuzakh plant, which was attacking the city. When the Toa Metru entered the Great Furnace, Vhisola and the five other Great Disk Matoran fused together to form a Matoran Nui, who then helped the Toa get inside. She was later forced into a Matoran Pod along with the rest of Metru Nui's population, but was saved by the Toa Metru. After her placement in the pod, the Toa Metru found evidence that Vhisola was the destined Toa Metru of Water, not Nokama (prophecies said that the Matoran who discovered the Great Disks were going to be the Toa). But the prophecies were false, placed by Mata Nui and supported by the Order of Mata Nui to fool Teridax. The tricked Teridax mentally changed Lhikan´s choices (who was going to give the Toa Stones to the prophesied Matoran), and made new ones (the Toa Metru), in order to spoil the prophecies. But, the prophecies being false, the Toa Metru were actually the ones destined to be Toa.

Mata Nui
Vhisola was awoken by the Toa Metru along with the others (the Toa turned into Turaga in the process), on the island of Mata Nui. After that, she lived in Ga-Koro for a thousand years, facing the darkness of Makuta who menaced the island with his infected Rahi. She is a guard in MNOLG with Shasa. After a thousand years, the Toa Mata arrived and defeated Makuta, the Bohrok invasion, and the Bohrok-Kal strike. When Metru Nui was rediscovered, Vhisola and the others constructed boats and returned. She then helped to rebuild it until the Staff of Artahka repaired the rest of it.
