"Freedom is the right of all sentient beings. No sacrifice is too great in the service of freedom. One shall stand, one shall fall. Autobots, transform and roll out!"Optimus Prime.Peter Cullen (born July 28, 1941) is a Canadian voice actor who is perhaps best known as the voice of Optimus Prime in The Transformers (he would subsequently reprise his role as Optimus in Michael Bay's live-action Transformers film series and the Transformers Prime and Transformers Rescue Bots animated series). In addition, he has narrated and played Coran (Raible in the original) and King Alfor (King Raimon) in the Lion Voltron (GoLion) series, the transforming spaceship/robot Ramrod (Bismarck in the original) in the 1980s anime series Saber Rider and the Star Sheriffs (Sei Juushi Bismarcknote ), Commander James Hawkins in the Vehicle Voltron (Dairugger XV) series, Eeyore in Winnie-the-Pooh, Venger in Dungeons & Dragons, the narrator, Murky Dismal, and Skydancer in Rainbow Brite, Eddie Spenser in Filmation's Ghostbusters, the Predator in the original film, King Kong in the 1976 remake, and KARR in Knight Rider. He also holds the milestone of being the first person to provide the voice of Mario (in the Donkey Kong segments from Saturday Supercade), and, for many years, provided voice-overs for Toonami's promos (as "the big guy"). Cullen also voiced Monterey Jack on Chip 'n Dale Rescue Rangers for the first season, but was replaced by Jim Cummings for the rest of the series (it should also be noted that Cummings voiced Monterey Jack in the five-part pilot movie "To The Rescue").Then, when the news broke that he was to return to voice Optimus Prime, the fandom rejoiced, giving the temporary Trope Namer (Cue Cullen) for And the Fandom Rejoiced.Then, when the news broke that he was not to return to voice Eeyore in the 2011 Winnie-the-Pooh film, people were not quite so happy. But thankfully Cullen returned six years later for a crossover with Doc McStuffins.The fandom rejoiced once more when he reprised the role of KARR in the new Knight Rider series. Even more so because KARR is a Transforming Mecha in this version.And, before you ask, yes: Optimus and Eeyore are his favorite roles.No relation to Bill Cullen, or that sparkly vampire dude. Also, not to be confused with Peter Mullan.Transformers also wasn't his first collaboration with Frank Welker. His earliest animation role was as Mighty Man in Ruby-Spears' "Mighty Man and Yukk" segments on The Plastic Man Comedy Adventure Show, with Frank as Yukk. He later voiced Sourpuss the family cat opposite Frank's Chomp-Chomp the family dog in Hanna-Barbera's Pac-Man series.
