Dan Green voices a lot of characters, it's hard to keep track of them all. He voiced Yugi preatty well in the original series. His voice as Knuckles is..so-so. I could go eiter way with him voicing Knuckles. In Sonic 06, even though the game was bad, I thought he voiced Mehpiles the Dark preatty well. He also is going to be the voice actor for Tetsu Ushio in Yu-Gi-Oh! 5D's, and it actually suits Ushio. He also has returned to voice for Pokemon, even though 4Kids no longer owns Pokemon. Dan Green is a good actor, but now he might just be voicing too many characters.

Dan Green is one of my favorite voice actors. He provides the voices of many memorable characters, and does a good job with expression. Shame he works for 4Kids but hes still a fantastic voice actor. The only problem is that many of his characters sound a bit similar. Yami and Knuckles sound very similar, and many of his characters, even if the similarity isn't so drastic, sound alot like Yami. When Knuckles talk, I just picture Yami speaking. He can vary his voice quite a bit though, such as when voicing Yugi Moto. The difference between Yugi and Yami's voice is amazing, yet Dan Green voices them both.

Dan Green is the best voice actor I've ever heard! I've met him and he's such a great guy! :D

Dan Green is not only a prolific voice actor for *gag* 4Kids, but he's also one of the very best VA's they've got with them, which is saying a LOT. The characters he can pull off, from the stern, serious and proud Yami/Atem to the young and gentle Yugi himself, almost always succeeds with believability shrouded in flying colors. I mean, he does Treeko, too. That's just bizarre!
However, (regretably), I'm one of the many who finds he was miscast as Knuckles the Echidna, tending to add a greater degree of gruffness, and a seemingly older "age," to Knuckles' voice than necessary. He does, however, manage commendable emotion and believability to the situations at hand; I'll give him that.
Overall, he's a talented VA in a company without enough of it. As long as he enjoys his job, which I doubt he doesn't, I urge him to keep on going. Great having you, Dan!
