You know the difference between how you feel traveling somewhere familiar and traveling somewhere you've never been before? Something like that. You're not nearly as at home, it's not as natural to you, you can't "let loose", so to speak.
And Mako has the edge because he's the one who came up with the voice, so he understand Aku's sound, vocal mannerisms, vocabulary, sentence structure, accent, and so on. There are many rules at play I'm certain he wasn't consciously aware of, and it would take some work to pull it apart and memorize the "rules". And then you have to record while remember them all, AND act well, which includes not sounding unaccustomed to your character or getting too hung up on the appearance of it that you neglect the finer aspects. And then you have to be bombastic and goofy as fuck, to play Aku. Some ad-libbing may also be involved.>>90772364
Are you him? I'm incredibly flattered you'd take the time out of your day to record this to respond to me. Not even being sarcastic. You do a good job.
