Ridiki originally worked as a forger, and crafted useful tools and supplies such as precious Kanoka disks and Kanohi masks from protodermis.
Ridiki spent many happy years living in the village of Ta-Koro on Mata Nui. He loved lava farming, which involoved creating useful stone tools by directing molten lava into specially-shaped channels. He was also a member of the Ta-Koro Guard, who were the village's defense force against Rahi attackers, sent by Teridax. In his spare time, Ridiki used to love surfing the lava flows of Ta-Wahi and raced the other Ta-Matoran in Ignalu. He was also known to be very short tempered, but was always quick to react and a great leader when needed.
After Teridax's death, he moved along with the others to Spherus Magna, and made his home in the Great Volcano with the Fire Tribe.
As Ridiki was resistant to extreme heat, it made him ideal for working in the tool and mask forges of Ta-Metru and the lava-farming plains on Mata Nui.
