Deviot is a general of Scorpius, but also a betrayer. He was responsible for Scorpius's death and had tried to kill Trakeena.
Deviot (whose name was based on the term 'devious') was a treacherous robotic alien who sought the power of Scorpius's cocoon. Soon after his appearance, he developed a strong hatred toward Maya, the Yellow Galaxy Ranger, and would often attack her first during battle. Deviot appeared on the scene with threeZords that he attacked the Galaxy Power Rangers andGalactabeasts with in battle. However, these Zords turned to good, having once been Galactabeasts. After continuous failures, Deviot stole the legendary Galaxy Book, and used its power to mutate. He was defeated, and joined forces with Captain Mutiny.
After escaping the Lost Galaxy, Deviot was attacked by Trakeena, and they both fell into the cocoon. The being that emerged was an amalgam of Deviot's evil and Trakeena's power.
Deviot shared many characteristics with Darkonda; both were treacherous and deceptive.
Deviot has a rivalry with the Yellow Ranger (just like in the Gingaman footage when you see Hikaru (GingaYellow) in battle with him).
Deviot and Trakeena can't stand each other, but he plans to kill her.
It is also assumed that Deviot worked for Astromena at one time due to the fact that when the data cards of the Psycho Rangers poped up he reffered to them as old friends and he knew what happend to them after the ranger last encounter with them.
