Kanohi: Calix, Great Mask of Fate
Weapon: Spiked shield and spiked spear
Fopi began his life as an architect in Po-Metru. Always slow to speak and even slower to take advantage of situations, it took Fopi millennia to actually raise his status from a small-time producer to a respectable designer who took commissions from the Po-Metru elite.
His unassuming and good-natured personality led him to see the best in Matoran which generally allowed others to manipulate him. Other architects often took credit for Fopi’s designs to launch their own careers. It was this flaw which allowed the leaders of Po-Metru to pressure him into designing fortresses during the Matoran Civil War. This caught the attention of the Onu-Matoran combatants which led to his capture. Having been tortured numerous times, Fopi eventually gave in. At the conclusion of the war, Fopi was left a broken Matoran.
Having discovered Fopi's wartime betrayal, Po-Matoran radicals targeted him for treason. The knife a Po-Matoran radical drove into Fopi’s wrist simply drove his anger deeper into his heart-light. Several decades after, Fopi's bitterness made him hate others and himself. He returned to his work as a cold, heartless machine.
Soon after, a spark was reborn in him as a Toa of Stone handed him the chance to redeem his broken life.
