Did Shredder just wake up one day and say 'I'm going to make some clones of myself! Really ugly ones!'
S1 E22Return to New York Part Two
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!!
S1 E24Lone Raph and Cub
Raphael (after catching up with Tyler after he ran off; twirling one of his sais): You can't sneak away from a ninja, kid.
TTyler
Leave me alone!
S1 E25The Search for Splinter Part One
[Donatello has just distracted a security camera at TCRI with a pigeon finger puppet.]
I don't know what's scarier: the fact that that worked, or that Don carries around a pigeon puppet.
S2 E8Secret Origins Part Three
[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.]
FUFirst Utrom
I hate walking on my tentacles.
SUSecond Utrom
Oh, shut up Krang!
S2 E13Return to the Underground
[Mike, Leo, and Raph are surrounded by monsters in the underground city, after Don had a dream and found a cure for the monsters.]
Him and his big ideas! C'mon guys! Let's go to the underground city! We'll have some laughs! We'll get eaten!
S3 E10Nobody's Fool
FFelon
Who-who are you? Who are you, man?!
NNobody
Who am I? I might just be a glimmer of hope for a lost city. I'm the guy the cops would thank if they knew I existed - but they don't. - Who am I? I'm Nobody.
S3 E11Christmas Aliens
Casey (while setting the table with April and looks up): Yo, what do you know? Mistletoe. Ain't we supposed to kiss or something?
AApril
That's enough mistletoe to make me kiss you. I'm afraid you'll need a whole tree. (They move to another part of the table and Casey looks up again)
Hey, hey, check it out. More mistletoe! (he puckers his lips and April walks away) April, wait up! (the mistletoe moves over to April) More mistletoe. There's no way out. You gotta kiss me. (April backs up; Casey and the mistletoe move forward; April goes around Casey, the mistletoe follows her) Look, it's following us. It's a sign. A sign from above.
April (taking down the mistletoe): Exactly. (April and Casey look at a pole with Raph and Angel sitting on top of it with ropes that extend over to April and Casey; Raph grins)
Raph (waving): Hiya, April. Whatcha got there? Mistletoe? (he chuckles)
AApril
Jones, did you put them up to this?
No! Never! Uh, maybe.
April (after a moment): Okay then. Pucker up. (Casey leans forward and April hits him with the mistletoe)
AAngel
Ooh. That's gotta hurt.
RRaph
Oh. Right in the kisser.
S4 E6Grudge Match
Yes, pizza sounds very appetizing right now. With pepperoni. And karma.
Season 5: The Lost Season
(Master Splinter and Ancient One meditating)
So much danger, never wanted this for them.
Splinter, I cannot meditate with you muttering like that. Besides my butt has fallen asleep.
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.
Your sons are capable, sort of.
Um, hello we're like five feet away. How about showing a little tack.
Master Splinter, when you say the Ninja Tribunal cost you your family. What are you talking about?
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)
Yoshi was my prized pupil and he assisted on becoming a guardian.
YYoshi
My lords, we must form an alliance. The Shredder's threat is beyond imagining!
CChikara
This alien bug imposter you called the Shredder, it's nothing to us. He is not the real Shredder!
YYoshi
Do not underestimate him, he may even the channel the evil of the one you fear.
KKon
This distraction, we must remain vigilance against the return of the True Shredder.
Masters, please reconsider.
KKon
We have spoken, go now and trouble us no more.
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)
Nothing, have the Tribunal heeded Yoshi. My master might be alive today.
(Splinter sheds a tear)
The Tribunal sees a bigger picture than we do, Splinter. At least I hope they do.
Is anybody going to tell us what the shell is going on here?
Real Shredder, True Shredder, Utrom Shredder.
How many Shredders are there?
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.
No one really knows what level of the dark depths spawned him.
(The story begins in Yamato, Ancient Japan)
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)
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)
