[This episode starts off with the Brothers engaging in yet another battle with the Kraang inside a warehouse]

Leo: Keep moving. Don't let them surround you. Failure is not an option.

Donnie: Technically, failure is always an option.

Raph: You know what else is an option? Slapping you!

Y/N: Stupid Kraang Droids!

Kraang: Kraang Grab Experiment 726! (Multiple Kraang Droid start coming at Y/N)

Y/N: Bring it on you toasters!

(The Swords are the bottom of their blasters)

Y/N: That's how I roll. [Kicks the last one into a bunch or crates]

Donnie: Mikey! On the right!

MIkey: Your right or my right? 

Donnie: [Hits a Kraanddroid in the head, but nothing happens] Are you kidding me? I hate this thing! [Raph comes in and takes it down before it shoots donnie]

Raph: Nice work. When we're done here, there's a marching band that needs a majorette.

[The team is successfully able to obliterate every single one of the droids and a piece of machinery that the aliens put into action]

Kraang: Kraang, the present is being a positive time to be the testing of the energy cannon.

Leo: Everyone stand your ground! [Machine humming.] On second thought, run!

Y/N: Don't have to tell me twice! 

[They all scatter dodging the blasts and Donne's staff his obliterating the top of it]

Donnie: Oh, come on!

Mikey: Dude, your weapon just exploded!

Donnie: How am I supposed to fight advanced alien technology with a stupid stick?

Y/N:(Joins Donnie at his side) Poke them with it till they get annoyed? (Chuckles)

Donnie: (Growls and throws his staff away. The team keep taking down Kraang droids until they backed into a wall and forced to take on the Kraang cannon)

[Theme song.]

Kraang: Kraang, destroy those who call themselves the turtles when that which is the signal is the signal that is given by me! Than take the one known as Experiment 726 so we can do experiments on the one known as Expertiment 726!

Y/N: That's not my name!

[leo throws a ninja star which causes a forklift to crash into the cannon and the rest of the Kraang droids]

Y/N: Nice one Bro! (Pats his shell)

Raph: Dumb luck.

Leo: Wasn't luck, my friend. And dumb had nothing to do with it.

Donnie: [Grunting.] Hey. Give me a hand with this.

Leo: A hand with what? [They all head back to base with a piece of a Kraang droid from the battle]

Raph: We're carrying this thing because why?

Donnie: Don't you want to understand how these things work?

Raph: I know how they work. You hit 'em till the brainy toy surprise pops out.

Donnie: That's your problem, Raph. You never think things through.

Y/N: What a surprise. (Chuckles as leo and Mikey does the same. Donnie places the broken Kraang droid on the manhole cover, but it's too big)

Raph: Was that supposed to fit?

[After a moment Donnie bangs on the robot to get it inside. Back in the lair the brothers are hanging out with april. While Raph hangs out with Spike. Y/N is sitting next to April while wathing TV.]

Donnie: This technology is light-years ahead of anything I've ever seen! Do you know what this is? [Rattling.]

April/Y/N: No.

Donnie: Neither do I! But I can't wait to find out! (Splinter comes in with another Bo staff for donnie)

Raph: Look, Spike. Donnie got another stick to break.

Donnie: With all due respect, sensei, I can't keep fighting alien technology with a 6-foot staff. I was hoping to upgrade my weapon.

Splinter: Mmm. A 7-foot staff. Interesting.

Y/N: (snickers)

Donnie: No, I meant using modern technology.

Splinter: Aah, a solar-powered staff.

Y/N: (Chuckles)

Donnie glares at Y/N, but turns back to splinter-

Donnie: I'm serious!

Splinter: I know, and yes you may upgrade your weapon.

Donnie': That's totally unfair! You can't just-- Wait, did you say "yes"?

Splinter: Ninjas have improved their arsenal for centuries. We are masters of adaptation.

Donnie: That is great! 'Cause with this technology, I will be invincible! What should I make? Electric sais? Multi-shot shuriken? Plasma swords! [Giggles.] I just gave myself goosebumps. You wanna feel? Eh?

April: Pass.

Splinter: But remember, technology is a means, not an end. It is you who must prevail in battle, not your weapon. Combat is not a video game.

Donnie: That's it! I'll turn combat into a video game! Thanks, sensei.

Y/N: Wait, we can upgrade our weapons?! (Splinter Nods) I wish you would've told me sooner! (runs to his room)

April: Hey guys! Check out this post I got.

Raph: Hang on, April, I just have to destroy Lame-onardo.(Beats Leo, Does a victory dance, and, than pushes away) So what's up? (Leo walks up and slaps Raph on the back of the head)

April: I set up a message board to collect unusual sightings around New York. People send in pics, videos I also get some stuff that may help us track the Kraang and find my Dad. Like this video of a gas explosion.

Leo: A Kraang droid.

MIkey: Where? Aah! Hunh! (Falls into water)

Leo: We'll check it out tonight.

April: Why not now?

Leo: Because it's daytime. We can't let anyone see us.

April: Well, I can.

Leo: April, think about this. It could be dangerous.

April: You know what else could be dangerous? Standing between me and my father. (Leo steps aside)

Leo: Okay.

[Heroic music playing on TV.]

Ryan: What do you make of this, Dr. Mindstrong?

[Beeping.]

Mindstrong: This is very disturbing, Captain, sensors indicate- [Alien screech.] [Crash!] Everything is fine.

Ryan: Great galaxies!

Crankshaw: Captain, what's happening?

Ryan: Dr. Mindstrong's been taken over by the Cortexicons.

Crankshaw: [Gasps.] What'll we do? What'll we do? [Loud smack.] Ow!

Ryan: There's only one thing we can do. Dr. Mindstrong must be destroyed. [Laser blasts.] [Scream.]

Leo:What a hero. [Thunderous metal clanging.]

[Some thunderous metal noises clang. The 3 brothers turn to see a robotic android that looks like a turtle.]

Metalhead: Take me to your leader!

MIkey: Leo, it's for you.

Leo: What is this thing?

Donnie: Gentlemen and Raphael, this is the future of ninjutsu.

Raph: I always thought the future of ninjutsu would be taller.

Mikey: Aw, he's so cute. (Tickles Metalhead's chin, but then-

Mikey back up in fear.)

Donnie: He doesn't like being tickled.

[Back with April]

Kraang: Is that which is the unstable mutagen ready for using in the experiment that Kraang is being ready to begin?

Kraang 2: The unstable mutagen will be tomorrow unleashing in the water supply.

April: [Gasps.] The water supply? Oh, no.

Kraang: Many infected humans will mutation. This is being a good way to perfect the mutagen to the point of perfection.

[April tries to get out of the ware house, but is blocked by a Kraang droid. She hides behind a crate}

April: Think ninja. Think ninja.

[April waited till the Droid was distracted, ran up,  and hit with a pipe. At first is was unfazed, but she hit it again which knocked it through the window. She sighs and leaves the warehouse.]

[Back in the lair]

Donnie: Isn't it cool? I reverse-engineered it from the Kraangdroid.

Leo: Okay. Why?

Donnie: So the drone can handle the dangerous stuff while we stay out of harm's way.

Raph: Oh, I get it. This is for wimps too afraid to fight.

Donnie: No, it's for wimps too smart to fight I mean- [Metal thumping.]

Mikey: Ooh! Let's call him Metalhead. Why, you ask? Because it's got a head and it's made of -

Leo: We get it.

Raph: I don't need a toaster to fight my battles for me.

Leo: This is ridiculous, Donnie. It takes the whole point out of being a ninja.

Donnie: It's exactly the point of being a ninja we adapt. Now watch this. Attack the drone. Give it all you've got.

Leo: You sure? I don't want to break your toy.

Raph: I do!

[Raph leaps high into the lair and flies directly at Metalhead, but Donnie simply has the robot catch Raph's sais in it's hands - and he then has bot quickly outmatch Raph without any effort whatsoever. Then, Leo and Mikey both attack at once. However, Metalhead easily bests them as well.]

Donnie: I kicked your shells! And I didn't even have to use the laser cannon! Face it, guys, with this thing I'm invincible!

Raph: Oh, yeah? You know what I mean.

Donnie: Sensei, I was wondering if I could take Metalhead for a spin tonight. -

Splinter: You may.

Donnie: That's totally unfair! You can't just wait, what?

Splinter: You have created this new weapon. We must see how well it works.

Donnie: Well, that's great. Thank you, sensei.

Splinter: But it is a test only. Do not take it into combat.

Donnie: No problem, sensei.

Raph: You're taking it into combat, aren't you?

Donnie: Totally! [Giggles.]

Y/N: (Runs up to his brothers) We're going into combat, than this is a good time to test out my new ninja claws!

(Do not own Picture)

Y/N: I call them the Beast fang claws! The knuckle duster makes my punches more powerful and the claws are ten times sharper than my old on. Now, let's go kick some Kraang!

Raph: I'm in.

[Donatello (controlling Metalhead from way back at the lair), along with Leo, Raph, Mikey, and Y/N head out of the lair and begin running across a rooftop in the wide city. However, Metalhead is VERY loud and clumsy]

Leo: Should we double back? I think there's a car alarm he didn't set off.

Raph: I kinda like it. It goes nicely with all the sirens and cries for help.

Donnie: Oh, come on. You guys are just jealous 'cause you're out there in the cold and I'm here eating Mikey's last slice of pizza.

Mikey: Hey! [Metal clanging.] Ow!

Y/N: Look, let's just find April.

April: Hello?

Leo: Hey, guys, quiet. Somebody's coming.

April: Guys, it's me.

Leo: April!

[The 4 brothers leap down while Metalhead stays on the roof]

April: Guys! I was just looking for you. [Whistiling as Metalhead falls in a dumpster] Aah!

Raph: Still, it's stealthier than the real Donatello.

April: What the heck is that?

Y/N: It's Donnie's latest "brilliant" creation Metalhead.

Mikey: Catchy name, huh? My idea. [Radio feedback.]

Donnie: Oh, sorry, April. I'm still getting used to the controls. Whoops. Megaphone button got stuck

April: Guys, we gotta do something. The Kraang are gonna poison the city's water supply with mutagen!

Leonardo: The whole city will become a disaster area.

Donnie: (through Metalhead) There would be mutants everywhere!

Mikey: Wow! Think of all the friends we'd make! (everyone stares crossly) Excuse me for being a "glass-half-full" kind of guy!

Y/N: You mean "a city full of mutants" kind of guy.

Mikey: Hmph!

Leonardo: Let's go!

Metalhead: Yeah! The Kraang don't stand a chance! (Leo puts his hand at Metalhead) What?

Leonardo: Donnie, I gonna need you to hang back. Metalhead is just too clumsy, it'll get in our way.

Metalhead: Clumsy?! (knocks down trash cans) I did that on purpose to emphasize my point.

Leonardo: You're not coming, Donnie. (April puts her hand on Metalhead's shoulder, he looks at her, and then looks down in sadness. Aprlil and Donnie watch from a rooftop, but donnie keeps adjusting Metalhead's head to look at April.)

Donnie: So you like heavy metal? [Nervous laugh.] [Clears throat.]

Leo: Looks like a Kraang picnic down there.

Raph: Ready to bash some bots?

Leo: Destroy some droids?

Y/N: Kick some steel?

Mikey: Clean some closets?(The three look at him) Uh, I meant to say crush some Kraang?

[They all leap down and take down a single Kraang Droid]

Y/N leaps on to a Kraang droid and-

Y/N: Oh Yeah!

Mikey: Booyakasha! (Leaps on two and punches them rapidly until Raph pulls him out of it)

[They sneak, but are found out by a mob of Kraang droids which start blasting at them.]

All: [Screaming.]

Donnie: (Donnie zooming in on April) Look at her, she so beautiful. On this monitor she can't tell I'm staring.

April: You do know that's not muted, right?

Donnie: (screams and falls backwards) Oh course, if it was muted, you couldn't hear me joking!  (He face palms on Metalhead's controller and presses the megaphone button, making his voice louder) Man, I hope she bought that.

April: (covering her ears) That's the megaphone.

Donnie: I know! (turns off the megaphone) So how do think the fight's going? (A Kraang energy cannon blasts through the building wall and part of the rooftop that Donnie and April were on)

Mikey: (screaming) They're everywhere! Run!

Y/N: Mikey stop coming to my cover!

April: Not great.

[Suddenly, however, the robots hear the Brothers and soon manage to corner them]

Raph: Leo, we're running out of - [Grunts.] Room.

Leo: We're trapped!

Mikey: Or maybe, they're the ones who are trapped! Hmm? No, it's us. [Glass shattering.] [Screams.] Aah-ha-ha!

Metalhead jumps on two Kraang-droids attacking them hands out of order) Metalhead: HIIIIIIIIYAA!

Leonardo: What are you doing? What is wrong with your arms?!

Metalhead: My hands aren't on my hips?

Leonardo: No! (Raph facepalms)

Metalhead: Sorry, forgot to press B. (puts it right and destroys Kraang) Hey Raph, how does it feel to be shown up by a toaster? (Raph feels embarrassed)

Mikey: Burn!

Metalhead: Yeah. I thought that was a good one. 

Mikey: No! Burn!!!

Metalhead: Oh right! (He sets fire to 2 Kraang-droids)

Y/N: I never thought I'd say this, but Go MetalHead!

MetalHead: You got it!

Kraang: That thing which does violence at Kraang used to do violence for Kraang!

[Kraang Droids are blasted down left and right by Metalhead]

Mikey: Aah! Dude!

Donnie: Oops! Sorry, Mikey.

Leo: Donnie, watch the friendly fire.

Donnie: Here's some for you! And some for you! And, oh, yeah, I saved a little for you too! How'd that taste? [Buzzing.] [Metal clinking.]

[Metalhead's laser blaster accidentally hits some explosives in The Kraang's lab, a Kraang brain is able to seize control of Metalhead]

Donnie: No! I lost the control signal! What's that Kraang doing? Uh-oh. Guys, if you can hear me, you might wanna run.

Kraang: The ones that which are called turtles and Experiment 726 will now be called turtles and experiment 726 that are destroyed!

Mikey: Whew! I was really afraid at the beginning of the sentence, but then I sort of just lost interest towards [Kraanghead pulls out blaster.] Ok. I'm afraid again. [Screams.]

Donnie: Oh, come on! Maybe if I can override-

Splinter: Donatello. The time for games is over.

Y/N: Donnie we need you! Our brother!

Donnie: (Donnie looks at the TV and gets up) You're right. My brothers need me.

Splinter: Wait! Here! [Throws him his staff]

[Donnie bows to his sensei and runs off to help his brothers. His brothers are taking n Metalhead.]

Leo: Give him everything you've got. He's gotta have a weak spot.

Y/N: I hope we survive long enough to find it.

[They all hit him rapidly, but it doesn't work.]

Mikey: This always works! Hiyah!(Kicks him in the private) Ow! Well, usually.

[They are all punched to the ground by Metalhead]

Kraang: Now Kraang will destroy you. Which one wants to be first to be destroyed by Kraang?

Donnie: Me! (Donnie jumps down from roof)

Y/N: You came!

Mikey: Donnie! Bangin' entrance, dude!

Donnie: You guys deal with the droids. I'll handle Metalhead.

Y/N: Eat this!

(Each knocked down a Kraang Droid)

Kraang: It is the maker of the tech which was the tech that was of the Kraang.

Donnie: Come on, gimme your best Gaah! [Donnie takes on Metalhead, but his weapon doesn't do anything. Soon, his staff is broken by a blaster.] Not again. (Notices a pillar breaking from Metalhead's attacks) That might work. Hey, Kraang! The one who is called your mother wears the boots that are made for combat!

Kraang: The comment that is made by you shows ignorance of Kraang! The ones known by you as mothers -

Donnie: Just come get me! (The Giant support pillar to fall on the robot itself, allowing the bo staff of his to somehow pierce into Metalhead's chest) Booyakasha!

Mikey: Sounds weird when he says it.

Raph: Sounds weird when you say it.

Kraang: That which is the revenge will be had on those who are call themselves the turtles and experiment 726.

Mikey: Nice job, bro!

Leo: Way to go, Donnie.

Raph: Yeah, not bad. Except for that part where you built the thing in the first place. And the part where it broke. And the part where it tried to kill us. And the part-

Donnie: Ok, I get it.

Y/N: (Wraps arm around Donnie) Hey, you made a mistake and you fixed it. That's a win in my book.

Donnie: (Smiles) Thanks, Let's go home.

(Back in the lair the 3 turtles are playing an arcade machine while Y/N has gone to take a nap)

Leo: Oh, so close to my high score. Oh! [Sautering iron buzzing.]

Splinter: What troubles you, Donatello? [Sighs.]

Donnie: This was all my fault, sensei.

Splinrer: You are responsible, yes.

Donnie: Yeah.

Splinter: Responsible for destroying the mutagen. Responsible for saving the people of this city. Responsible for defeating advanced technology using only ingenuity, bravery, and a stick.

Donnie: Thanks, sensei. Maybe you're right.

Splinter: I am.

Donnie: I guess with proper training, there's nothing better than a wooden stick. Except a laser guided, missile-launching wooden stick. [Beeps, buzzes.]

All: [Groaning.]

Donnie: It's not supposed to do that! Run!

All: [Screaming.]

Post Credit Scene

Y/N is sleeping in his room, but suddenly has visions of Kraang lab-

Kraang: Experiment 726 and 727 are not in the place which Kraang has placed them.

A kid Y/N and a female kid cheetah are running through the compound looking for a way out-

kid Y/N: Come on, we gotta get out of here!

???: Which way brother?

Kid Y/N: (Points to a left hall-way) This way!

They keep running until they find a room full of portals. They head for one, but are stopped by a Kraang droid-

Kid Y/N: Back off brain droid! (Leaps at it, but is grabbed and thrown down, but near the portal. The female cheetah comes to his side)

???: Brother! (She looks at the portal and than back to her brother)

Kid Y/N: Sister go through the portal! I'll distract this thing!

???: We'll find each other again I promise.

Kid Y/N: Wha-(He didn't finish as she pushed him through the portal)

Kid Y/N: Sister!

Y/N wakes up sweating and panting heavily as he comes to two realizations-

Y/N: I have a sister and the Kraang have her.

Hope you enjoyed the chapter
