In an earlier version she had a full set, and I removed teeth later after looking at some of her sprites as reference; I might change it. Thanks for the feedback!

Undyne is not Undyne without that wide bright smile, have you tried putting more teeth in that black space? I think she would look better that way

Yeah, It's very neat ;)

@Fusionnist: It's true! I like how it was subtly made more and more important as the story went on.

@Friend: Thank you kindly! :)

That determination thing looked like a joke at the beginning of the game, but was introduced in a serious way...it fills you with determination.

seeing Undertale reborn like a beautiful beautifly gives you hope for your future...It fills you with determination
