Varian

Varian was the name of the Toa that "The Shadowed One" had trapped in a stasis tube. Currently, the element, tools, color, and gender of this Toa remain unknown.

Early Life
Like most Toa, Varian was originally a Matoran, but the Toa's element remains unknown. It is known that Varian later became a Toa but the island of the Toa's origin and whether or not Varian was part of a Toa Team remains unknown.

Capture
Some time later, Varian was captured by Dark Hunters and taken back to Odina, where the Toa was then placed in a Stasis Tube and put on display in The Shadowed One's chamber. Varian was later seen by the Piraka when they were assembled in the Shadowed One's chamber when they joined the Dark Hunters.

Spherus Magna
After Makuta Teridax was killed by a fragment of Aqua Magna, the Matoran Universe was damaged and the inhabitants had to join the mass exodus to Spherus Magna to escape the crumbling robot. It is unknown if Varian managed to escape this.
