Sonic: Roger Craig Smith is alright, but this definitely isn't his best performance. Still baffles me why they haven't replaced him with Ben Schwartz yet, or brought back Ryan Drummond. Roger, I love ya', but you're also my least favorite Sonic actor.
Tails: Great. There's not much to say, Kate Higgins was rockin' the voice since 2010, and Collen o' (I won't even try to spell her surname) is just as great.
Knuckles: Made a profile post about him a few days ago.
Shadow: Kirk Thornton still isn't as good as David Humphrey, but he's great-come a long way from
his ghoulish, emotionless Shadow.
Rouge: Incredible. Karen Strassman wasn't anything special in the previous 2010's games, but she's really improved in Team Sonic Racing. I consider her just as great of a Rouge as Lani Minella.
Omega: Unless your name is Sonic 06, it's pretty difficult to mess up Omega. He sounds as great as ever thanks to Aaron LaPlante. Much better than the last guy from Forces.
Silver: Amazing. Pete Capella will always hold a special place in my heart, but Bryce Papenbrook is also great, even if he's very different from what I'm used to hearing.
Blaze: Definitely my favorite of the current voice cast. I hope Erica Lindbeck sticks around, she might be my favorite Blaze so far.
Vector: Keith Silverstein is THE Vector. What a chad.
Amy: Fine. My feelings on Cindy Robinson are pretty much the same as Roger-I'm fine with her VA as it is, she just doesn't do much for me.
Big: I honestly didn't notice it change throughout the series history-Jon St. John was always what I heard. But apparently his current VA is Kyle Hebert-well, he sounds just as much of a Big as Jon did. It's great.
Eggman: Mike Pollock, please don't ever go away. He's just an incredible Eggman and it's hard to imagine him being replaced, even in a post-Jim Carey/Robotnik world.
Metal Sonic: I'm tired of this bucket of bolts just using basic beeps, bops, and boops. Can we please get Ryan Drummond back, if not for Sonic, for Metal? I wouldn't mind Roger voicing him even. He has a voice, for crying out loud, use it!
Zavok: Who?
Omochao: Same person as Blaze's. She does an incredible job.
Cream:
