Underfell AU - Undyne

What's the only thing which could possibly be as awesome as Undyne from Undertale!? Underfell Undyne!! For those that don't know Underfell is an Undertale AU where all the characters are out to kill the protagonist and generally display more 'evil' characteristics than their Undertale counterparts. The only exception to this being Flowey, who actually ends up helping the protagonist. 

Made entirely in SAI.

I am complete Undertale trash.
