The Rat King is a large reddish-brown anthropomorphic rat. He has an extremely long snout, a small black nose, black whiskers, black eyes, rounded ears with pink insides, pink hands and feet, and a pink zigzagging tail. He has a very smug expression. He wears a yellow crown with three prongs and a red cape with a white fluffy collar and yellow clasp.
"Take, then, thy victory!"
"Do with it what thou wilt in these underground realms, for never wilt thou return to the surface!"
"In truth, it would be undignified for a king to fight as well as a simple adventurer."
"Have thy moment of victory, thou wilt not have my crown!"
"Ah, mayhap I have lost, yet am I not still a king?"
"And in truth, thou hast won, yet art thou not still a weird ugly dice?"
Post Endgame:
"Thy victory is fleeting, and my majesty is eternal! Thou shalt cower in terror yet!"
