A POWER Rangers villain turned into a real-life baddie when he butchered his roommate with a sword, stabbing him 10 times during a fight over a gal, cops charge.

Ricardo Medina Jr., 37, who played Deker, the evil rival of Red Ranger Jayden in 2011’s Power Rangers Samurai, faces 26 years behind bars if convicted of the bloody gutting of Josh Sutter, 36, at his upcoming trial.

Medina was arrested just days after the Jan. 31, 2015, killing in the home he and Josh shared in Palmdale, Calif.

But cops bought his story that he was defending himself and his galpal when an enraged Josh burst into his bedroom.
