Creator / Takehito Koyasu
Takehito Koyasu is a seiyuu born in—*WHACK*

What!? I was just getting to that bit!

Anyway, he is currently the most prolific seiyuu (voice actor) in the business. And when we say prolific, we mean it, with lots of varying roles he can pull off easily. Starting from a Determinator, to a calm, cool, intellectual, sarcastic character, to a nobleman to just plain comic relief/gay character. He created Weiß Kreuz, and is a part of the Weiss group, alongside the other leads: Shinichiro Miki, Tomokazu Seki, and Hiro Yuki. He is a true Man of a Thousand Voices.

Has an alter-ego named "Zazel". Zazel sings the theme song for the CD drama starring Weiss' rivals, Schwarz.

According to Anime News Network, he has the most number of roles in anime - as of September 2015 a total of 112 more roles than the next highest on the list.

It shall be noted, also, that he's a Promoted Fanboy. Yep, he was a long-time Mobile Suit Gundam fan before landing the roles of Zechs, Gym, Mu and Frederick.

Currently working on a series of CD dramas called Velvet Under World, which may or may not be a Weiß Kreuz spin off. For the most compelling arguments in favour of that, "Velvet Underworld" is Weiß Kreuz's first opening theme and VUW's main character's name? A.Y.A.

He seems to be a good friend of Hikaru Midorikawa and, as a result, there's lots of instances where he plays characters who are rivals with Midorikawa's character, usually with Koyasu's character being the instigator of rivalry. Koyasu has also replaced Kaneto Shiozawa in many roles since the latter's death and can be seen as his successor as they do sound rather similar.

Western counterparts? For California, Crispin Freeman, Keith Silverstein and Steve Blumnote . For Texas, Jason Douglas and J. Michael Tatum. Per his Running Gag (see below), we can also count both Nolan North and Troy Baker as his other Western counterpart candidates. Tomokazu Sugita seems to be shaping up to be his successor.

Koyasu's Roooooles! Koyasu's Roooooles! From the various series! Take a look if you please! They're going to Californiaaaaa....

These tropes are not associated with everything in the universe! It was I, Takehito Koyasu!

Hey, did you just describe Takehito Koyasu?
