"You know… who you are… You were always different." Jaller. He gets better.
"Get off!" Nidhiki
"Hey! What's happening?" Krekka
"No… this is my lifetime's journey. Yours lies beyond. I am proud to… have called you brother… Toa Vakama." Lhikan
"But I can't defeat him myself! … Roodaka?" Sidorak, as Roodaka leaves him to deal with an angry Keetongu alone.
"Is this the end, then? Is this what it feels like?" Matoro
"Would you shut up? Rule number one: don't annoy the giant, tentacled monster, or don't they teach that one in the Shadowed One's school?" Carapar, ironically, shortly before doing exactly what he berated his partner for.
"We all meant to come. Teridax wouldn't let us. We all knew we would benefit by your experience, your power, your very presence." Spiriah to Miserix, but the latter isn't touched by the words of his former follower, and consumes him.
"No! My will must prevail! I am the stronger! I am —" Alternate Teridax (from The Kingdom)
"No, Makuta. You once told the Toa Mata that you could not be destroyed, because you were nothing. You were wrong — it is because you are nothing that I can destroy you. You have no heart, you have no spirit, you have no reason to exist -– even your hate is a pale reflection of what once burned in you. You survive out of habit, monster, and habits… and minds… can be broken." Alternate Matoro (from The Kingdom)
"Very clever, Toa. True, a Universe with only drowned Matoran would not be of much use to anyone. But they must be taught respect." Alternate Tuyet (from Dark Mirror)
"Excellent. We could ransom these for a good price." Ancient, but The Shadowed One didn't want to share.
"No need. I have only to release the Shadow Takanuva I have already made, and they will dispose of the attackers. And then I can go back to work in earnest. And then I can..." Tridax
"I will deal with you later." Icarax
"Gorast, no! Don't you understand? You're all doomed!" Krika
"Krika was right. Krika was right." Gorast
" Amazing. If I could tap this energy, I could — Wait! Yes! I see it now — It's so absurdly simple. I can control this storm! All I have to do is -- YAARRGHH!" Mutran
"Bitil! Come back here! Don't… don't leave us." Antroz
"'Come back' indeed… what do I gain by saving them? When I make it out of here, Teridax will see that I am his most trusted lieutenant! He'll see --" Bitil
"No, he won't." narrator
“You made an excellent effort, but they don’t remember who tried the hardest… only who won. Today, that is I. Goodbye, brother.” Teridax
"C'mon, McGinnis. Laugh it up now, you miserable little punk. LAUGH! I can't hear you!" The Joker, again... sorta. It is a long story.
"Loser." Darkseid.
"Aw, phooey." Chucko, after Chronos leaves him at ground zero of the asteroid that wiped out the dinosaurs. He may have been brought back once the timeline was fixed, but come on.
"It's... beautiful. Isn't it?" Darkseid, again. Told you he got better.
"Yes. Yes, it is." Lex Luthor, as he and Darkseid vanish into the Anti-Life Equation. Batman is not convinced either of them died, but it was the Grand Finale.
"Then...Grundy gets his reward..." Solomon Grundy. He almost got better.
"You twisted pink rabble of a hominid! I'm not done with you! I'll get outta this, and when I doooooooo—!!!" Gorilla Grodd

"Leave! This... this is still my bridge, trooper! Go back and tell Winfield to watch. Tell him... Matthew Marcus... knew how to die."
"Put me... down. Leave me. I do not wish to spend my last moments with half-formed Terrans. [as the boy scouts who found his body start crying] Why?.." Shiva, the best General of the racist Neosapien regime
"You never... you never answered my question... you do care about J.T., don't you? Tell him... I never told Maggie... remember..." Alec DeLeon
"Do your worst, you sea devils. I'll make my stand with Old Freebie. You can crush me but you can't crush my spirit!" CRUSH "Argh, my spirit!... I request a Satanic funeral!" Old Man Waterfall
"With my last breath, I curse Zoidberg!" Farnsworth, although he ended up getting saved. It was still a Crowning Moment of Funny for him.
"YOU! You will regret what you have done this day! I will make you regret ever being born! You're going to regret you ever left you mother's womb, where it was warm, and safe, and wet! I'm going to show you pain you never knew existed, you're going to see a whole new spectrum of pain! Like a RAINBOW! But! THIS rainbow is not just like any other rainbow, it's—" Scrotus
All the examples above are from Same As It Never Was a.k.a. the Bad Future episode. There's a reason Turtles fans consider this episode the very apex of Nightmare Fuel.
