100,000 Years Before
Long ago, Tahu was once an Matoran created by Mata Nui. In his early life, Tahu along with the Toa Mata traveled to Angel Island where they met Copan The Echidna and Tikal The Echidna. Upon Tikal The Echidna for the first time Tahu went into delightment. The echidnas had assigned them to be the guardians of Mata Nui by using Chaos Emeralds to revive him should he fall. Copan trained Tahu along with the Toa Mata in order to learn to fight whilst the Knuckles Clan built the Toa Canisters to allow them to escape. Later he discovered that the Brotherhood Of Makuta led by Teridax(who had overthrown Miserix and imprisoned him in the Twilight Cage) had corrupted the Chaos Emeralds with the Dark Star to destroy Mata Nu and is now invading many planets having Ur-Didact sending his Forerunner army to invade Angel Island and hunt down the Chaos Emeralds for the Brotherhood. Realizing that they would be no match against the Forerunners and the Brotherhood. The Toa Mata were concealed themselves in the Toa Canisters to save themselves from the hands of the Forerunners, alongside Tikal and Copan who concealed themselves in the Master Emerald to not only stop Chaos from destructing Angel Island but also saving themselves from dying at the hands of him and the Forerunners. After Mata Nui was destroyed by the Teridax and his Brotherhood, the Toa Canisters were shot out and landed in Angel Island which was where Mata Nui was destroyed and remained for 4000 years.

Present Day
4000 years later in Angel Island, Tikal The Echidna and Copan The Echidna had found the Toa Canisters and used the Master Emerald in order to summon the Toa. As the Toa came out of the Canister they collapsed and broke into pieces having Tikal and Copan rebuild them.
