Does anyone you know speak a lot like a fictional character? (You can include yourself.)

Nope.

Me, but not regularly.
I can change my voice to sound like Prussia(Japanese).
Though my throat usually hurts afterwards.

I have a teacher who can imitate Scooby-Doo exactly.

Other then that, no.

Only what you've said.

Well, I can imitate some of my paborito characters fairly well. I only mimic their speech patterns though. I don't actually sound like any one character that I know of, and I can't think of anyone else I know. :/

My friend, Sara, sound EXACTLY like a pitched up Russia. She even has the accent, cause she likes to mimic foreign accents. Russian is her favorite, and she'll do it all the time. She also says a lot of the same things. Seriously, one time, she unknowingly quoted Russia. She doesn't even watch anime. One time, I told her that she sounds EXACTLY like Russia, and she was like, "O.o What?"
My cousin, Andrew, sounds like Hapon from Hetalia. He has the same quiet voice, and he tends to mix up his r's and l's a lot because of a vocal issue he developed. Again, I once told him he sounds like Japan, and he was like, "WTF?"
Then there's my arch enemy, Angela. She's evil. She's Satan in high heels and make up. She sounds like the antagonist from melokoton Girl, Sae. Demonic. I swear, she has the same fake-innocent and high-pitched voice!

Well I talk exactly like Veronica Mars... LOL
