Michelangelo: Can we keep her?

Meet Casey Jones [1.4]

Michelangelo: [Whispering] Donatelloo, Donatelloo, if you build it, we will ride....in turtle style!

---

Casey Jones: Yes, I can see the family resemblance.

Michelangelo: I'm the pretty one.

[While finishing his story about the Shredder.]

Splinter: He serves no great purpose. He fights no great evil. He is great evil.

The Shredder Strikes Back Part One [1.17]

[The Turtles are watching a football game.]

Raphael: Panthers, rams, bears--they've even got dolphins! You'd think they'd have room for something more... reptilian.

[Pause.]

Raphael: Say what?

The Shredder Strikes Back Part Two [1.18]

Splinter: In the hands of a true ninja master, anything is a weapon.

---

Shredder: You freaks have been a thorn in my side long enough. No one opposes the Shredder. And now I will have my revenge for our last encounter. Say farewell to each other -- while you still can.

Michelangelo: Oh yeah, Mr. Spikey-Pants? Well, you’re the one who should be saying....uh...farewell to, um... to yourself!

Raphael: (Being sarcastic) Oh yeah, Mikey. That got 'im.

Return to New York Part Two [1.22]

Michelangelo: Did Shredder just wake up one day and say 'I'm going to make some clones of myself! Really ugly ones!'

Shredder: Ah, the power, I have almost forgotten! The Sword of Tengu! The sword in which I'd laid villages to waste, brought castles to ground, vanquish armies! The sword that I used to conquer Japan and give power to the Tokugawa clan! It is mine once more!!

Lone Raph and Cub [1.24]

Tyler: Leave me alone!

The Search for Splinter Part One [1.25]

[The Utroms have been forced to leave Earth, as Shredder has discovered their whereabouts and spread a virus through their base, shutting down all electronics, including their exo-skeletons.]

Return to the Underground [2.13]

[Mike, Leo, and Raph are surrounded by monsters in the underground city, after Don had a dream and fond a cure for the monsters.]

Season 5: The Lost Season

(Master Splinter and Ancient One meditating)

Splinter: So much danger, never wanted this for them.

Ancient One: Splinter, I cannot meditate with you muttering like that. Besides my butt has fallen asleep.

Splinter: My apologies, Ancient One. But the Ninja Tribunal troubles me more each day, I cannot allow their foolish judgment to cost me my family. Not again.

Ancient One: Your sons are capable, sort of.

Michelangelo: Um, hello we're like five feet away. How about showing a little tack.

Leonardo: Master Splinter, when you say the Ninja Tribunal cost you your family. What are you talking about?

Splinter: I am talking about my beloved Master Yoshi and of a time in the past. Yoshi-san was a guardian then, pledged to protect the Utroms. He came to alist the Ninja Tribunal's aid.

(In a flashback where Yoshi and Ancient One are visiting the Tribunal)

Ancient One: Yoshi was my prized pupil and he assisted on becoming a guardian.

Yoshi: My lords, we must form an alliance. The Shredder's threat is beyond imagining!

Chikara: This alien bug imposter you called the Shredder, it's nothing to us. He is not the real Shredder!

Yoshi: Do not underestimate him, he may even the channel the evil of the one you fear.

Kon: This distraction, we must remain vigilance against the return of the True Shredder.

Ancient One: Masters, please reconsider.

Kon: We have spoken, go now and trouble us no more.

Splinter: The mighty Ninja Tribunal ignored my master's warnings. And because of the Tribunal's call in difference, one of the countless victims of the Utrom Shredder would be my Master Yoshi. And the Tribunal did nothing.

(In a flashback where the Utrom Shredder had slain Master Yoshi)

Splinter: Nothing, have the Tribunal heeded Yoshi. My master might be alive today.

(Splinter sheds a tear)

Ancient One: The Tribunal sees a bigger picture than we do, Splinter. At least I hope they do.

Raphael: Is anybody going to tell us what the shell is going on here?

Michelangelo: Real Shredder, True Shredder, Utrom Shredder.

Donatello: How many Shredders are there?

Splinter: My sons, it is time you know the true story of how this all began. Of an evil darker than all evils, a primal force of malevolence that was and is the Original Shredder.

Ancient One: No one really knows what level of the dark depths spawned him.

(The story begins in Yamato, Ancient Japan)

Ancient One: But back in the year 300 AD in Yamato. The Shredder rose from some foul stinking pit, in the form of a terrible tengu.

(People are running as the Shredder Tengu destroys everything in its path)

Ancient One: An demon that had but one goal to subjugate the world and to turn it into his own personal empire, ruled in agony and destruction.

(In the Lap of the Gods temple)

Splinter: The Shredder Tengu spread his evil everywhere, he seems unstoppable. There were five great warriors in Japan in that time. Their courage and their victories were legendary.

Ancient One: And you young punts already have the honor of meeting them. There was Hisomi. Chikara.

Splinter: Juto.

Ancient One: Kon. And perhaps the most skilled and ambitious of them all, Oroku Saki.

Leonardo: Saki, Shredder's fake human identity. He was real?

Ancient One: Don't interrupt, Leonardo. Just listen, so these five great warriors were summoned before the Emperor, who informed them. They were the world's last hope.

Michelangelo: Whoa, no pressure or anything.

(The Emperor shows them their enchanted armors)

Splinter: The Empire's greatest craftsmen had forged armor for the warriors. Special armor engraved with protective spells and talismans of purity. Armor they will soon wear into battle against the evil Shredder Tengu.

(The five warriors went out to battle the Shredder)

Splinter: This fight overwhelming them, they refused to give up. They have vowed to fight until the very end.

Ancient One: Saki's attacks were the most savage, the most damaging.

(The battle was victorious when Oroku Saki delivered the final blow)

Oroku Saki: I am Oroku Saki, demon! Let my name be the last sound you hear!

Ancient One: It was he who finished the demon.

(A celebration of the five warriors begins)

Splinter: The Emperor held a great celebration and decree that the warriors would be known as the Five Dragons. There could be no higher honor.

Ancient One: He awarded them their own banner. The Three-Toed Sign of the Dragon, but the celebration was premature.

(Back in the battle was Saki was about to finish the demon)

Ancient One: Saki's battle with the Tengu had been spot on law of the physical plane.

Oroku Saki: I am Oroku Saki, demon!

Shredder Tengu: There is greatest in you warrior, I can make you a god among these insects. Every wish fulfilled, every dream made real. You can rule all, have all, just around me inside your soul. And the world will be yours!

Splinter: The demon's words ignited some dark part of Saki, he accepted the offer.

(The demon's spirit is transferring into Saki's body)

Ancient One: Invisibly, the Shredder's evil spirit merged with Saki's so as even as the warrior landed the final blow. The tengu was only an empty vessel. The dark spirit of the Shredder had filled Oroku Saki and now he was host to the greatest evil the world had ever known.

(Oroku Saki laughs evilly)

Splinter: Oroku Saki's betrayal plunged Japan into an age of darkness. The malevolent essence of the Shredder swelled within him and all around him. There's seem no limit to the evil of which he was capable.

(The Shredder use his powers to destroy Japan and build an impenetrable stronghold)

Splinter: Having created an impenetrable stronghold and his only true opposition to strong. Saki became the most feared warlord of all, his name was spoken in whispers.

Ancient One: And the name they all whispered was the Shredder. The Dragons vowed to defeat to the Shredder at all cost, they needed to increased their power so they sought out mystical knowledge.The ancient spells and wisdom that will allow them to stand against the Shredder's might. They've studied hard and learned much, the Dragons scoured the globe for masters of the mystic arts who will be willing to teach them.

(Each of the Dragons went to find the masters of the mystic arts)

Earth Ninja: You shall not interfere!

Metal Ninja: The usurper will pay for her irreverence!

Shredder: You have defile my name long enough!

(The Shredder use his magic to lift Karai up and slam her into the wall)

Leonardo: Karai!

Metal Ninja: Wait not for her! After all, you are the ones who sealed her fate!

Leonardo: What the shell are you talking about?!

Fire Ninja: Have you not yet realize?

Water Ninja: Without you, we could never have free the Shredder.

Wind Ninja: For it was you that free us.

(The heralds transform into their original forms)

Leonardo: The Mystic Ninjas! No!

Earth Ninja: When you took that crystal from Karai on behalf of Agent Bishop. You set us free.

Leonardo: No! No!

Wind Ninja: Yes, you set a chain of events in motion that led to our master's rebirth.

(The bone demon use the amulet to summon the Mystic Ninjas)

Bone Demon: Dark masters! The Ancient One has finally led me to the Ninja Tribunal monastery.

Fire Ninja: Excellent. The amulet we have granted you will cloak your presence there.

Water Ninja: You will remain invisible to all who encounter you.

Bone Demon: Masters, the four kame children resisted the amulet's spell. They were able to see me, what if--

Wind Ninja: You need not concern yourself the children. They are powerless.

Water Ninja: Find the Pool of Sorrow, part its waters with the amulet's energy.

Earth Ninja: Beneath it lies the master's gauntlet, helmet, and sarcophagus.

Metal Ninja: Use them to fulfill your only purpose of existence. Resurrect the one True Shredder!

Wind Ninja: Yes! Raise our master from his long sleep! So he may once again rule unlimitless power over all the world!
