Voriki/Greg

Voriki/Greg is a major character in Reviving Bionicle 3. He appears in the 1st episode of Reviving Bionicle 3, where he is created by Tahu and Onua to be used as a sacrifice to LEGO to show their appreciation for bringing back BIONICLE. In episode one he is naive and innocent, has a great love of life, and is happy to be included in all of Tahu and Onua's antics. However he is ultimately intended to be a sacrifice for LEGO, so he is tricked into believing that the only way to achieve true happiness is to be lowered into the garbage disposal. Greg is happy to comply, until Kopaka reveals that this will kill him, and tells Tahu and Onua not to sacrifice anyone anymore. Kopaka is then pushed into the garbage disposal, but Greg is able to save his life. Unfortunately, Greg is killed in the process.

Surge and Evo were able to recover Greg and use his brain to test Denmark, rewriting his personality completely and giving him a new body and a new name: Voriki, who was a rumored seventh Toa in the early days of BIONICLE. As Voriki, he wanted to become a great hero, and he stopped Pohatu 2015 in the episode "Gearboxes", as well as Kapura in "Fake Hero". He later met Takanuva, the real seventh Toa, and tried to befriend him. Takanuva didn't like Voriki, as he believed he should be the only seventh Toa, and grew to resent him. When Evo attempted to kill Takanuva with Denmark, Voriki jumped in front of him and took the shot, killing him in the process. The others buried him outside.

In Home away from home, they rebuilt Greg in a toa form, bringing back his personality, but gutting his memory of Takanuva and Good guy 2008, which they then attempt to retrieve.
