Question: Who is the American actor that provided the voice for a character with the name of T'Challa?

 Created by writer-editor Stan Lee and penciller and co-plotter Jack Kirby, he first appeared in "Fantastic Four" #52 (July 1966). The Black Panther (T'Challa) is a fictional superhero appearing in American comic books published by Marvel Comics. <SEP> James C. Mathis III (born November 28, 1974 in Brooklyn, New York) is an American actor best known for providing the voices of Black Panther, Bulldozer and King Cobra in the animated television show "". <SEP> Zachary Throne (born April 3, 1967 in Hollywood, California) is an American actor and musician who has appeared in a wide number of television, film and stage productions and on numerous rock, pop and soundtrack albums.  Throne is a self-taught, musician who sings, plays guitar, bass, drums, and piano – and is self-taught on all instruments.  He is the son of Malachi Throne and Judith Merians and is the brother of Joshua Throne.  He earned a Gold record in 1992 for his work on the soundtrack album to the television series "The Heights", on which he performed guitars, bass, piano and vocals as well as co-starred in the series.  The album yielded a hit single, "How Do You Talk To An Angel" (on which Zachary performed on) that was #1 on "Billboard" for two weeks in November 1992.  As an actor, Zachary is best known for playing the recurring role of "Howard", the radio station manager/drug dealer on "Beverly Hills 90210" and for playing "Danny" on the FOX series, "Party Of Five".  As a singer, Zachary has sung on many TV and radio jingles.  He provided the singing voice for the character, "Mark Winkle" on the television series, "California Dreams" as well as the singing voice for the character, "Greg Brady" in the films, "The Brady Bunch Movie" and "A Very Brady Sequel".  Currently, he resides in Las Vegas, Nevada where he performs in many shows.  From 2012-2014, he was the lead singer/lead guitar player/bass player for the Sin City Sinners, a group that also featured former Faster Pussycat guitarist and co-founder Brent Muscat as well as Slash bass player, Todd Kerns.  .  With the group, he recorded two albums, "DIVEBAR Days Revisited" and "A Sinners Christmas 2", both released in 2013. <SEP> K9, occasionally written K-9, is the name of several fictional robotic canines (dogs, the name being a pun on the pronunciation of "canine") in the long-running British science fiction television series "Doctor Who", first appearing in 1977.  K9 has also been a central character in three of the series television spin-offs: the one-off "K-9 and Company" (1981), "The Sarah Jane Adventures" (2007–2011) and "K9" (2009–2010).  Although not originally intended to be a recurring character in the series, K9 was kept in the show following his first appearance because he was expected to be popular with younger audiences.  There have been at least four separate K9 units in the series, with the first two being companions of the Fourth Doctor.  Voice actor John Leeson has provided the character's voice in most of his appearances, except during Season 17 of "Doctor Who", in which David Brierley temporarily did so.  The character was created by Bob Baker and Dave Martin, to whom rights to the character still belong; consequently, Baker's spin-off series "K9", which is not BBC-produced, cannot directly reference events or characters from "Doctor Who", though it attempts to be a part of that continuity.
