Loki (pronounced "Low-Kai") is a fierce and loyal demon warrior and friend to Diabolico (to whom Loki gave a spider/scorpion-shaped amulet to as a token of their millennia-long friendship) and Vypra. He serves as the dumb muscle of the demons, and was considered expendable by Queen Bansheera despite his loyalty. When Diabolico was destroyed for the first time, Loki and Vypra were anguished by his death and considered the newly matured Olympius as a mere child who would not make a suitable leader. After losing favor with his mother, Olympius discovered that Bansheera considered making Vypra and Loki the new second in command and plotted to eliminate them by having Vilevine bury them alive. The two managed to survive and escape to where the demons were first imprisoned and brought Diabolico back to life to help get rid of Olympius.
After regaining her body (at the expense of Vypra's life), Queen Bansheera allowed Loki to personally go after the Rangers, calling him her "favorite" servant. In truth, however, Loki was being used in a plan to destroy the Power Rangers; during the resulting battle, Bansheera telepathically took control of Diabolico's body and forced him to use Loki's bazooka to take aim at the Rangers, an act that would also risk harming Loki. The Rangers managed to survive the blast, but Loki was fatally wounded and died in Diabolico's arms, his body exploding and reduced to ash in the typical way monsters were destroyed. This proved to be the final straw for Diabolico, who began actively working against his queen to avenge the death of his friend.
The monsters Loki created were mainly earth-elemental, including Quakemon and Elestomp. In battle, Loki normally used a two-pronged staff as his weapon, but in "The Wrath of the Queen", the final episode he appeared in, he used a bazooka that was in the shape of a dragon's head. Loki could also expel electricity from his eyes.
Loki is voiced by David Lodge.
