Mine is Tom Kenny who does the voice of Spongebob Squarpants , Ice King , Eduardo ( Faster's ) and many more. He is talented and can morph his voice to make so many different sounds . 

Oh my god! I loved Spongebob! I wold either pick him, or the voice for Timmy turner from Fairly Odd Parents.

Gotta go with Billy West.  So many characters...
Doug Funnie
Ren and Stimpy
Several characters on Futurama
Just to name a few of my favorites, but the list of his work goes on.

Jack DeSena. I really liked his voice for Sokka in Avatar: The Last Airbender. In my opinion, Sokka was the funniest character and his voice really complemented that. I had hoped he would be in Avatar: Legend of Korra, but he wasn't. I think he would have been a perfect Bolin.

Mel Blanc, Frank Welker, Billy West.

well mine is Billy West for the fact he did Doug

   I would probably have to say John Kricfalusi. He's the voice oh Ren from the Ren and Stimpy Show. He never fails to make me laugh when Ren freaks out!

Oh, my God! Yours is Tom Kenny? What a coincidence (sort of)! Mine is Rodger Bumpass, who voices Squidward Tentacles XD! I love the way he portrays him.

My favourite voice actors are Jennifer Hale and Ali Hillis. I grew up hearing Jen in so many cartoon's and both her and Ali voice my two favourite video game characters now.  

This is a fun question.  I'm going with H. John Benjamin or whatever the name is of the guy that does Archer and Bob from Bob's Burgers.  He has a perfect voice for sarcasm and witty comments.  He is as entertaining as it gets.

I have to agree with Zanderlex. Patrick Warburton is my favorite. I first heard him in the first Tak game, then again in Open Season (the animated movie) as Ian. I enjoyed both, and loved how his voice annoyed my sister so badly. lol

David Hayter: Voice of Snake in Metal gear solid series.

Michael Bell: Raziel's voice in Legacy of Kain series.

Simon Templeman: Kain's voice in Legacy of Kain series.

warmaker :

I dunno. For me he sounds so lethargic. But then again, the character is so lethargic. Not much of a challenge. I like Bobs burgers though.

My favorite voice actor would have to be Mel Blanc the man of a 1000 voices. If you ever watch the looney tunes or the Jetsons or the Flintstones Then you heard his voice. Most known for Bugs, he is one of the greatest voice actors in history.  An in his life time Mel has done over 5000 voices for cartoons  an doing more then one in the same cartoon. Like bugs an daffy fighting.  yeah old Mel had a nice run in his day And will be missed in the cartoon world. So when your watching those old cartoons 1 guy did most of those voices your laughing at.

Ok.....its gonna be to long to list. Who should I start with?

Veronica Taylor a voice actress. She is the voice of the original ash from Pokémon, Oh! And also not to mention, she voiced as may, ash's mum, yuya from samurai deeper kyo and much more.

Tara strong, she is the voice to twilight sparkle from mlp also....for those who don't know she voiced as the original Timmy turner in the fairly odd parents, bubbles from powerpuff girls, boh from spirited away for those who don't remember the gigantic baby, scooby doo movies and many more.

Daran Norris, hes voiced as Timmy's dad in the fairly odd parents. There are some other anime or cartoons that he voiced as. Sangorou from naruto, some voiced from samurai jack, some voices from fosters home for imaginary friends, some voice overs from Dexter's laboratory, the replacements, danny phantom and more.


I could go on, but yeah. I decided to stop here. ^-^

Christopher sabat for me. Hands down the best Anime voice actor in english.

Johnny Yong Bosch (if I spelt that right) is hands down my favourite. Even though his voice doesn't change no matter what role he does it's always perfect. He was amazing voicing Lelouch and it's the reason I actually prefer the dub over sub in Code Geass.
