Voices I Think Fit Undertale Characters

I took some voices from a bunch of games and movies and tv shows which I thought would fit these Undertale characters pretty well. Feel free to put your opinions in the comments.

p.s. I've never actually played Undertale before so watch this with a grain of salt. I'm mostly going off the character's appearance.

How I discovered the voices:
Kimberly Brooks voices Jasper from Steven Universe

Kyle Rideout voices Thorax from My Little Pony.
Zach Callison voices Steven from Steven Universe
ProZD, or SungWon Cho, voices... A lot different game characters and tv show characters actually, but he's active on YouTube and was an iconic viner.
