He's also the animal voice of pretty much every show or movie ever created EVER.

Seriously. If it was a show or movie that needed animal noises, Frank Welker is responsible for them.

I'll give you 2 easy Gundam ones

Lockon Stratos from Gundam 00 has the same VA than Urahara from Bleach

Amuro Ray from the First gundam has the same VA than Seiya from Saint Seiya

Frank Welker has been around for along time.

Yuri Lowenthal has played not only revengemo Sasuke from Naruto, but also Simon from TTGL, as well as Spinzaku from Code Geass.

The same girl who voices Starfire from Teen Titans voices Nia from TTGL before the time skip.

Of course, Patrick Stewart(AKA Captain Picard AKA Professor Xavier) voices Master Yupa in Nausicaa.

Hmm no mention of Mark Hammil that did among many others, The Joker (batman animated series), Senator (Metaloclypse), and Fire Lord Ozai (Avatar)

Speaking of Avatar Iroh and Aku (Samurai Jack) have the same VA too

And provided the voice for both Supermans in the Legion of Superheroes cartoon. He also plays teenage Ben Tennyson, but that's not something to be proud of.

Cree Summer, aside from voicing nearly every black female depicted in western animation over the past two decades, also has played Penny from Inspector Gadget, Elmyra Fudd from Tiny Toon Adventures, the newest Blackarachnia, and the green M&M in the M&M commercials.

You probably already know Grey DeLisle plays Mandy from the Grim Adventures of Billy and Mandy, Vicky from from FOP, and Azula from ATLA. You probably didn't know that she plays Black Canary and has a fantastic singing voice. And yes, that is Dr Horrible's NPH singing with her in that link. TBATB is still awesome by the way.

Edit: Only if Dee Bradley Baker isn't available at the time. Those two have the market cornered.

Don't forget his game roles. He also did Luke in Tales of the Abyss and the MC in Persona 3. It's kinda like he, Vic Mignona, and Johnny Yong Bosch have the market cornered on teenaged Japanese heroes. I shat a brick when I realized ToA managed to get both him and Bosch in the same game, because I always figured they had enough vocal overlap that it would always be one or the other.

And Yosuke Hanamura in Persona 4, where Bosch was the voice of the young detective Adachi.

EDIT: Apparently he, Yuri Lowenthal that is. was also the voice of Pharos and Ryoji in P3.

Did you know that the voice of this rapping dog was also the voice of the dad from the classic english dub of Totoro?

How was this not mentioned?

Did you know Mark Hamil voiced the joker? B:TAS
