Mirloc is the major antagonist in Power Rangers S.P.D.
When the Power Rangers first learn about Mirloc, he's being held in a high security prison on a planet with no reflective surfaces because he can use them to escape. Sky goes to interrogate him for information about a copycat criminal named Slate. Mirloc agrees to tell him him what he knows, but gets him into telling his saddest story. Sky tells them about his father the first S.P.D. Red Ranger, who was killed protecting the innocent. Mirloc torments Sky and uses one of his tears to escape, and laughs knowing that he was the one who killed his father. Mirloc uses his mirror to the core five of Rangers for Gruumm, and also manages to imprison the Omegamax megazord, but the Omega Ranger destroys the mirror, which releases his captives.
The monster compliments the rangers efforts but says they still can't beat him, especially Sky saying he and his father are both worthless. This doesn't shake Sky's teammates one bit saying that their friend is a great ranger like his father was, even so Mirloc still says they're going down. Jack decides to prove the madman wrong permanently, Jack hands Sky his delta morpher and tells him to take his father's murderer down for good. Sky seems unsure, but Jack tells him he has to do this for his father. Realizing his friend is right Sky takes the morpher, and becomes the Red Ranger, Mirloc still thinks he will win no matter what color Sky is. Mirloc's arrogance is proven wrong when Sky uses the Battlizer to bring Mirloc in. He is sent to a prison on Verinox 12, where there isn't any sunlight, meaning that no reflections can exist for him to use as a means of escape.
Mirloc resembles Monsieur D'Arque, both in appearance and personality.
