Who my favorites are is mixed between multiple era's of TMNT. So, I'll just list off my favorite VAs for each turtle as these are the voices I hear in my head whenever I read a TMNT comic.
Leo: Eric Bauza
His voice debut for Leo was in one of the summer shorts "Turtles Take Time," but it really started becoming its own when Eric came back in the Batman v. TMNT crossover movie. His voice for me took whatever was good about 03 Leo and expanded it. His voice sounded refined, reserved, and let his stronger emotions shine when it mattered. Definitely a voice fitting for a leader.
Donnie: Rob Paulson
I know people don't like this voice, but last I checked, I wasn't people so...yeah. Rob is just a really talented guy and I feel that he brings out the nerdy and eccentric nature for Donatello. This show proved that Rob can pull a more sentimental and serious side for his preformences that I think people just don't him enough credit for. However, it's not lost on me that may be "slightly" biased. Mostly because I grew up with a lot of cartoons that featured Rob's voice.
Raph: Nolan North
Nolan North. This guy is THE Raphael for me. Everything I like about Raph is all thanks to North's preformence in the 07 movie. He's gruff, slight Brooklyn accent is on point, and my lord can this guy make Raph sound like the scariest mother fucker when he's angry. Not only that, but he nails Raph's softer side in a way that no Raph has been able to replicate for me, making him the complete package for what a perfect Raph voice should be.....So yeah, I think his preformence is pretty good. :T
Mikey: Robbie Rist
That's it, the best Michelangelo for me. Wayne Grayson is too raspy for me, Mickey Kelley is the same for me. Greg Cipes sounds way too much like Beast Boy for my liking. Townsend Coleman, while iconic and I do really like his voice, it's just not the one for me. Robbie is the right amount of silly and free spitred, but knows when to turn it the fuck off. I feel Mikey's silly side gets flanderized a lot and it's good to remember a TMNT that played him just right.
There you go, my favorite voices. What do you guys think, agree? Disagree? Wanna say my tastes are trash, and that I should go kill myself? Let me know! I'd love to hear what you guys think? :)
