Coru was a Zora assassin and secret agent. Unwaveringly loyal to King Tiburon, he was an expert in the tactics of stealth and infiltration. He was first, and last, called into action on Epoch Day 7. After Patriarch Darmoto rejected an alliance with the Zora, King Tiburon sent Coru to Goron City. His mission was to install a new leader more favorable to the Zora’s and kill Darmoto if necessary. However while in route to his target on the slopes of Death Mountain he was spotted by Corgoro. With his plot discovered Coru attacked the Goron in hopes of keeping his mission a secret, but was killed in the subsequent duel.
