Kopaka is an Ice Toa Mata being among the warriors to find the Chaos Emeralds and Master Emerald to reawaken Mata Nui and is one of the major protagonists of Super Smash Bros. Crossover. He serves as the second in command of the Toa Mata with Tahu being the leader.
About 100,000 years ago, Kopaka was an Matoran created by the Great Spirit Being Mata Nui until he was assigned to travel to Angel Island alongside the rest of the Toa Mata to train themselves with the Copan The Echidna with the Knuckles Clan building the Toa Canisters. He along with the Toa Mata helped the Knuckles Clan defeat their arch nemesis the Nocturnus Clan and imprison them into the Cosmic Chamber. This resulted in Ur-Didact and his Promethean Forerunners into hunting down the Toa Mata, forcing them to conceal themselves into the Toa Canisters whilst Tikal The Echidna and Copan The Echidna concealing themselves in the Master Emerald. He along with the Toa Mata's canisters were shot out into Angel Island landing where Mata Nui was destroyed at the hands of Teridax.
