Least Favorite Roles For Your Favorite Voice-Actors

[Forsaken Lover]

So I finally figured I'd give Naruto Shippuden a try. Sure the parts of the manga I read post-timeskip were awful but maybe the beginning wasn't so bad I thought.

I was right. The beginning of Shippuden is quite awesome and introduced me to one of my favorite voice-actor's best roles ever.

So yeah, this all relates back to the topic at hand. I'm sure most people here are at least a little familiar with one Johnny Yong Bosch.
As the voice of Vash and Ichigo, he's pretty damn famous as far as VAs go. However, in Naruto Shippuden, he voiced the villain Sasori. This has to be his best role since Vash and it even rivals that. The cold, sinister speech perfectly captured Sasori's inhuman yet tragic nature. His Hollow Ichigo is nice but anyone can sound threatening when they laugh like a lunatic. The fact he sounded just as twisted yet only spoke in soft, gentle tones is just very impressive to me and why I love him in this role.

YouTube is run by douchebags so most people can't even see the vid I uploaded because of copyright blocking. However, that's why I put it on my phootobucket.

Well...that's enough from me. Who are your favorite voice-actors and their best roles?
