Danger Rangers Mission 547 was the pilot episode that spun off the Danger Rangers animated TV series. Mission 547 was originally released in 2003 as a direct to video project. Jonathan Harris was the original voice of S.A.V.O., the computer that alerts the Danger Rangers team when "...Dangers abound!" Mr. Harris passed away in 2002, so when the show went to series in 2004, Charlie Adler took over for the ever pompous, always on the alert S.A.V.O. character.
