Galacta Knight: Committed mass genocide against the Ancients, thus causing the "Galactic Crisis." Sure, the Ancients probably deserved it, but genocide is still genocide.
Morpho Knight: F[redacted] this dumb butterfly buffoon. When I saw that little moth swoop in to kill Soul Forgo and rob him of a BANGER boss battle for a boring Meta Knight reskin (EVEN THOUGH WE HAD PHANTOM META KNIGHT FOR THAT).
Glunk: MORTAL WORDS CANNOT DESCRIBE MY HATRED. FOR THESE F[redacted]ING RATS. I WANT TO DIG MY THUMBS INTO THOSE BULL S[redacted] BUG EYES!!! F[redacted]. THESE. VERMIN.
