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.

When the inhabitants of the Matoran Universe evacuated the crumbling Mata Nui Robot, it is also unknown if anyone freed Varian or if the Toa's tube was retrieved.

Trivia

 * Greg Farshtey created Varian out of a list of gender-less names.
