Omni, often referred to as the Magnificence, was the true antagonist in the TV show Power Rangers S.P.D.. Omni was a being that Emperor Gruumm answers to and he was the true leader of the Troobian Empire. Gruumm searched for a way to bring Omni to Earth. He currently resides in a chamber onboard the Terror Spacecraft and he had the ability to control anyone's mind.
Gruumm had used all of his resources to prepare for the arrival of Omni on Earth by turning the Terror Spacecraft into his body which is created from stolen resources. With this newfound power, Omni was intent on ruling the galaxy until his robotic body was eventually destroyed by the S.P.D. B-Squad Rangers in their S.W.A.T. Megazord and Omni was killed in a massive explosion.
