Full Circle Portraying

""Is it any more ironic that the same guy that did the voice of Garfield [Lorenzo Music] did the voice of Peter Venkman in the Ghostbusters cartoon? While Bill Murray was the live-action Peter Venkman, and he also did the voice of Garfield in The Movie!""

Think of it as a magnified Hey, It's That Voice!. Full circle portraying is where two or more characters have officially been portrayed by the same actor/actress in more than one occasion.

However, this might not count if both/all characters are from the same series. For instance, Animal and Bunsen where both voiced by Howie Mandel in the first two seasons of Muppet Babies, but they were voiced by Dave Coulier in every other season.

It's common that one is the Poor Man's Substitute for the other.

Japanese and English dubs

 * In the Japanese dubs of Rumiko Takahashi's Ranma ½ and Inuyasha, the title characters are both voiced by Kappei Yamaguchi. In the English dubs, Richard Ian Cox did the voice of male Ranma in seasons 4 through 7 and he also did the voice of Inuyasha.
 * In The Melancholy of Haruhi Suzumiya and Lucky Star, Haruhi and Konata are voiced by Aya Hirano in Japanese and Wendee Lee in English.
 * In Final Fantasy VII and Kingdom Hearts, Reno and Axel are voiced by Keiji Fujiwara in Japanese and Quinton Flynn in English.
 * They also share the same voice actor in French. And Spanish. And German.
 * Son Goku from Dragonball Z and Morrison/Masamune from Pokemon have been voiced by Masako Nozawa in japanese, and Sean Schemmel in english.
 * Morrison's Brazilian voice actor was also the Brazilian voice of Teen Gohan. Since Gohan is also voiced by Masako Nozawa, the trope workes there as well.
 * Masako Nozawa did the voices of Goku in Dragon Ball GT and Guilmon in Digimon Tamers, while Steven Blum provided the voices for Guilmon in the english dub and Goku's voice in Dragon Ball GT: Final Bout
 * Speaking of Digimon, similar to the Ghostbusters example, Michael Reisz played Ice Devimon in Tamers and Dave Wittenberg played him in Frontier. Takuya of Frontier was played by Reisz also in most of his forms, but to save his voice from all the insanely over-the-top screaming, he didn't do the voice of Takuya's final two forms (which, ironically, didn't scream as much as the other forms did when they were introduced.) Instead, Wittenberg did those. Dave, why do you keep stealing Mike's parts?
 * Light Yagami and Setsuna F. Seiei are voiced by Mamoru Miyano in Japan and Brad Swaile in the West, leading some (even on this Wiki) to declare Swaile the English equivalent of Miyano.

Live-action films and Animated series

 * As stated above, Garfield and Peter Venkman from Ghostbusters are portrayed by Bill Murray in the live-action movies and Lorenzo Music did their voices in the animated series.
 * Michael J. Fox portrayed Marty McFly in Back to The Future and Stuart Little in... well, Stuart Little. David Kaufman did their voices in the animated series.
 * Kamen Rider Dragon Knight dub: Kivat's voice actor plays JTC and Kiva-la's VA plays Kase. That makes their battles the Duel of the Cute Talking Transformation Trinket Bats. Also, Len is voiced by the actor for Len's Japanese counterpart Ren.
 * Both Ryan Reynolds and Nolan North have played Deadpool and the Hal Jordan Green Lantern, the former both in live-action and the latter both in animation. For bonus points, they're both alliterative names.

Western Animation

 * Mako did the voices of Aku From Samurai Jack and Iroh from Avatar: The Last Airbender. After his death, Greg Baldwin provided the voice of Iroh and did the voice of Nano Aku in Fusion Fall.
 * Shaggy from Scooby Doo and Robin from Batman have both been voiced by Casey Kasem and Scott Menville.
 * Many Starscream voice actors have also played the Cobra Commander - more than not, actually. Chris Latta was the original version of both, Michael Dobson was Unicron Trilogy Starscream and the Commander in two OVAs, and Charlie Adler was movie Starscream and the current voice of the Commander. Tom Kenny (Transformers Animated) and Steve Blum (Transformers Prime) will have to wait their turns!
 * Transformers' tendency to self-reference also leads to much homage casting. Several voice actors have played different incarnations of the same character, even when the new version is very different from the previous version. The current Optimus and Megatron are also the first Optimus and Megatron, Peter Cullen and Frank Welker. Beast Wars and the Unicron Trilogy also share their Optimus and Megs, with Garry Chalk and David Kaye, yesssss.
