So I just thought, what the heck, let's make a list of all my noncanonical character and OC voices, just because.

I'll probably come back and edit this list later, either if I change my mind, or new characters are introduced, but, anyway!

Gaster would be voiced by Benedict Cumberbatch.

So, of course, that means Jeff would be voiced by Martin Freeman.

Firhaur would be voiced by Peter Cullen. He's got the right kind of deep voice for a dragon.

And Dagiel would prrrroooobably be voiced by J. K. Simmons. Who also plays one of the best video game characters ever, Cave Johnson.

Also, this is one of the best video game lines ever.

[There should be a GIF or video here. Update the app now to see it.]

Anyway! Voices. There ya go.
