I haven't exactly put every detail into it yet... but an update is more than necessary as I'm nowhere near as good at coloring as I should be... I need to practice. And color and shade as I need to for this piece to work.

"Heh. Interesting. It seems as though your eyes both work now. Unlike when I beat you... I'll be fair and fight you with only one eye open."
"How dare you! You think this is funny!?"

"Not at all~ And the scar on my head is proof that I won't. Throwing that spear immediately after transforming was underhanded, but for justice."
"Why are you doing this if you know what justice is? Why are you killing innocent monsters when you are one yourself!?"

"Personal reasons. You're right to be loyal and prideful in who you are and those you love. You are righteous as you fight to kill me and avenge the fallen I've killed while protecting those beyond you."
"You're a sick twisted dog. How can you stand living with yourself as a murderer?"

"There's more to it than meets the eye, but the reason is simple; I'm morbidly interested in you showing your determination!"
"Very well! I'll show you the power of all of these hearts beating as one!"

"I'm honored to fight you... I see the dust is with you..."
"And soon your dust will be, too, as I, Undyne, WILL STRIKE YOU DOWN!"

"Yet I've smited you already~"
"...you think so? Truth is, you're going to have to try a little harder than THAT!"
