"AAAAAGHHH! I've been double-crossed! Help! Help! SOMEBODY HELP! I've been framed! HELP! Please, you gotta help me. Be a pal. Call that beetle... Call anybody,... Mama? MAAAAMAAAAAAA!!" Lampwick before turning into a full donkey
"No...Please don't! I don't want to—" Vexen, shortly before being assassinated by Axel
"You are the Superior's—. Forgive me, Zexion. This was a fight I should not have started." Lexaeus after Ansem(SoD) takes control of Riku and quickly cuts him down
"You can't do this!" Zexion, before being drained of his life force by Riku Replica (commanded by Axel)
" Why...Kingdom Hearts...Where is my heart?" Saix
"I wanted to see Roxas. He...was the only one I liked... He made me feel...like I had a heart. It's kind of...funny... You make me feel...the same... Kairi's in the castle dungeon. Now go." Axel, during his Heroic Sacrifice
"Nooooo waaaaaayyyyy!" Demyx
"How could you...Roxas..." Luxord
"No... No! I refuse to lose to such a bunch of losers! I think I'm...I'm fading?! No, this isn't... the way I...I won't...ALLOW..." Larxene

"This... is hardly... the end. Your Darkness...I gave it all to you. My dark shadow... lingers... someday... someday, I shall return!" Ansem/Xehanort's Heartless when defeated by Riku in Chain of Memories.
"No... you were right. I failed you, Terra. Perhaps I've no one but myself to blame for the darkness inside you. And now, I've done worse... raised my Keyblade against you and Ventus. My own heart is darkness!" Master Eraqus
"Now look what you've done!!! My Bugs! (voice gets higher pitched like one on helium) My bugs! My bugs, my bugs, my bugs, my bugs, my bugs, my bugs, my bugs, my bugs, my bu-" Oogie Boogie as he looses his bugs, which one of them gets crushed by Santa
