Guess what, everybody? It's finally time for the showdown with the Tallest! The fate of Earth depends on the outcome of this battle! (Well, not exactly, since the Irkens already hate the Tallest now, anyway. 'Course, you never know, they might come back.) Alright, let's DO THIS!

Chapter 27: Dethrone

After following Tak through the Massive, the team had finally made it back to the hangar, where they met up with Star Wolf. "I see you finally made it." Wolf said as they approached. "So, where's the Tallest?"

"The Tallest got away, but the soldiers and the adults should've escaped by now." Nigel responded.

"Yeah, we saw a lot of ships take off. They must be gone by now. Let's get out of here before we're toast." With that, Star Wolf, Ava, Dib, and Tak and FIR hopped into their ships and took off to Earth, with Nigel, Rachel, Zim, and GIR watching them.

"'Guess we should be heading back down, too." Rachel said to Nigel.

"And this time, I'm staying!" Nigel decided.

"Leaving so soon? But the party's not over yet!" They all looked around (except GIR) to see where the voice came from. The room began to shake. In that instant, the ceiling exploded and the Almighty Tallest came flying down in their giant SIRbot.

Nigel instantly recognized it. "HEY! That's the same robot you had back on Flora!"

"That's right!" Red replied. "I don't believe our robot was properly introduced. Nigel Uno: MEET DESTIR (Destructive Empowering SIRbot Terrorizes Impudent Rats)! The most powerful SIRbot in the Irken military!"

"This baby will use the power of the Wisps against you!" Purple followed.

"Watch and learn!" Red continued as the robot's eyes turned cyan-colored.

"LASER!" the Tallest shouted, and with that, DESTIR fired two lasers from its eyes, which made a circle on the floor around the heroes. The circle collapsed, causing the team to fall downwards. (Play Egg Dragoon's Theme from Sonic Unleashed!)

Nigel, Rachel, Zim, and GIR were then falling down an incredibly long hole, past a bunch of collapsing debris from the exploding Massive. Nigel grabbed onto Rachel, then grabbed GIR, who used his rockets, while Zim used his jetpacks. The four of them landed on a large circular platform and stood on it as they fell further.

During their fall, they could hear music playing, and looked up to see the mariachi band on a smaller platform of their own. "LOOK OUT BELOW!" the band leader shouted as they fell past the heroes into the pit, while still playing their music.

"ROCKET!"

"SPEED!"

They looked up to see the Tallest coming their way, their robot's eyes orange and light-blue from using the Wisps' powers. The Tallest were then flying next to the platform as Nigel asked, "Uhhh, quick question: if we're already falling to our doom, why follow us?"

"Just because you're falling doesn't mean you won't survive somehow." Red answered.

"So, we're going to make sure you don't survive!" Purple followed.

"Get ready, kids! If the burning atmosphere doesn't get you, then DESTIR will!" Red continued.

"Not before you fall first!" Zim retorted.

"Sounds like a challenge!" replied Red. "Alright, kiddies! Let's brawl!"

"Kids Next Door: BATTLE STATIONS!" Nigel and Rachel shouted in unison.

Boss fight: DESTIR

"Say your prayers, kiddies!" Red exclaimed as the robot's eyes turned red. "FLAME!" The robot shot fire blasts at the gang, but they easily avoided.

"That glowing part on its chest looks strange! Try aiming for that!" Zim suggested, noticing the green spot on its chest.

"Sounds reasonable to me!" Nigel said as he shot his blaster at the green spot, which seemed to damage it a bit.

"GAH!" exclaimed Red. "Try some of this! CUBE!"

"FLAME!"

The robot's eyes turned dark-blue and red as it shot a red cube in the center of the platform, which exploded and knocked the heroes off. Zim and GIR activated their rockets and got back on, while Nigel held onto the edge with Rachel holding onto him, and climbed back up.

"GIR! Fire at the green spot!" Zim ordered.

"YES SIR!" GIR fired his missiles at the weak spot, which damaged the robot some more.

"Stupid robot! We're gonna need back up!" Red said.

"SIRBOTS!" Purple shouted. A group of four SIRbots shot up from below and landed on the platform.

"It's always something, isn't it?" Nigel asked rhetorically. The four of them fought and took out the SIRbots with no problem. Rachel picked up the last one and threw it at DESTIR's weak spot.

"Grrr!" Red growled. "ORBOT! CUBOT!" The Tallest opened their cockpit and tossed their robots down on the platform.

"CLOAK!" the Tallest shouted as DESTIR turned invisible.

"YAY! WE GET TO BE IN THE FIGHT!" Cubot shouted as he and his companion pulled out laser guns. "HERE WE GO!" He and Orbot began firing at the heroes. Zim and Rachel quickly dodged and rolled up to the robots, then knocked the guns out of their hands, with the guns falling off the platform afterwards.

"Hmm, not bad." Orbot said. "But we're so much more than that." With that, Orbot retracted into a ball and began flying fast through the air, rapidly bouncing off Rachel whenever he could. Cubot, on the other hand, was a cube and was trying to get above and smash Zim. Nigel then ran to Rachel's aid and grabbed Orbot, who was immediately trying to shake out of his hands. Just before Cubot could attempt to smash Zim again, the Irken shot the robot with his goo gun, causing him to stick to the ground. Nigel then banged Orbot against the foothold, making him dizzy.

He then placed Orbot on the foothold as Rachel walked back a few feet. "And Rachel's going for the goal!" she exclaimed as she charged to the robot. "SHE SHOOTS!" And with that, Rachel kicked Orbot, sending him flying. Orbot conveniently hit the invisible DESTIR's weak spot, making it show itself. Orbot fell into the pit afterwards.

"UGH! Stupid kids! You won't feel so big after this!" Red said as the robot's eyes turned cyan and bright pink. "LASER!"

"SHRINK!" With that, DESTIR fired a bright pink laser at Rachel.

"Rachel, look out!" Nigel he ran and pushed her out of the way, taking the hit himself. When it cleared, Nigel looked to see he was once again tiny.

"Nigel!" Rachel exclaimed, immediately running over to pick up her shrunken friend.

"HA! That got ya!" Red exclaimed. "Now, how 'bout some o' this!"

"Not on my watch!" Zim shouted as he dashed toward the robot and hopped onto its chest.

"Oh yeah? ROCKET!"

"DRILL!" The robot fired its left drill hand, which came back toward Zim. Zim immediately leaped off, tricking the drill into digging into the chest.

"AHH! NOO!" The Tallest screamed as their robot took serious damage.

"Rachel, you think you can toss me onto the robot's arm?" asked the still-shrunken Nigel on Rachel's shoulder. Rachel nodded, picked him up, and tossed him onto DESTIR's shoulder. He then creeped into a small crack on the robot's arm and started to blast a few of the wires. He quickly hopped back onto the platform and returned to normal size as the arm exploded, releasing a few snacks from the arm.

"NOOO! OUR SNAAAACKS!" the Tallest cried.

"Nice going, Soldier!" Rachel praised.

"That's it! TAKE THIS! ROCKET!"

"DRILL!" The drill fired again and shot into the center of the platform, destroying it. DESTIR then shot downward ahead of them and broke through the bottom of the long hole. The next thing they knew, the heroes were outside in space, falling fast down to Earth, choking from lack of oxygen.

GIR thought fast (for once) and pulled out three helmets from his head. Zim, Nigel, and Rachel quickly put them on, so they could breathe. "WHEW! That was close!" exclaimed Nigel.

"Don't think you're safe, yet!" said Red from below them. "FLAME!" DESTIR shot more fire blasts at them as they fell, but they were able to barely dodge. They breathed a sigh of relief when they landed on another platform. DESTIR was then preparing another attack. "LASER!"

"DRILL!" The drill became electrified as DESTIR swung it at the heroes, but they quickly ducked. They ducked once more as the robot made another swing. Nigel and Zim took the time to shoot the robot in its weak spot. "That thing has to be getting weak now!" Nigel figured.

"Don't think so, yet! CUBE!"

"SPIKE!" At their command, DESTIR fired two rows of spiked cubes, trapping the team in-between. The robot fired giant spikeballs at them, but they were able to jump and avoid. "No good. Let's try this! LASER!" Red shouted as the dark-pink eye became cyan-colored. DESTIR shot a laser on the side of one of the end cubes, making it bounce off down the rest of the rows. The team squeezed in the gaps of the lasers and kept their positions until the laser and the cubes were gone.

Before they knew it, the green light on the robot's chest went out and it was beginning to malfunction. "WHAT? The energy levels are dropping!" exclaimed Purple.

"Don't go down on us now!" demanded Red.

"Now's our chance! GO, ZIM!" Nigel exclaimed. Zim once again ran up and got onto the robot's chest.

"Grrr! DRILL!" DESTIR once again fired its drill, which missed Zim and dug into the robot's chest. "NO! NOT AGAIN!"

Nigel, Rachel, and Zim exchanged glances and jumped onto the robot, making their way up to the head. "H-HEY! STAY BACK!" Purple cried. Once they were up on its shoulders, Numbuh 1 charged his blaster and shot at the cockpit. He then threw Rachel upwards, and the Tallest looked in horror as the blonde leader came and smashed through the protective glass with great force.

She then knocked the Tallest out of the way and started beating away at their controls. "NO! OUR ROBOT!" Red cried. Rachel hopped off afterwards.

"Here! Let me dry your tears!" The Tallest then noticed Zim standing on the side.

"No! NO!" Red exclaimed as Zim launched two mechanical tentacles from his PAK and wrapped around the Tallest. Zim then swung them around in the air, and the Tallest screamed as they were sent flying. He then pressed the self-destruct command on DESTIR, and Zim hopped off as the robot activated its rockets and shot upwards. Once he was at a high distance, the robot exploded into red and purple fireworks, which formed the word "Earth!".

"Hooray for Earth!" GIR exclaimed.

"Yes!" Zim agreed. "Hooray for Earth!"

"ALRIGHT! We did it!" exclaimed Nigel as he and Rachel hugged. The two hugged for several seconds until Zim interrupted.

"When you two lovers are done, we have to get off this thing before we reach the atmosphere!" The two immediately stopped hugging and saw that they were closer to Earth.

"Zim: activate your jetpacks!"

"Can't! It's out of fuel! GIR?"

"Sorry. Had to make room for the muffin!" GIR replied as he pulled out another muffin and ate it.

"How does that stuff fit in him, anyway?" Nigel asked rhetorically. The four screamed as they were about to fall into the atmosphere, but they silenced when they were stopped by an unknown force. Before their very eyes, Jirachi appeared before them. (End song.)

"Jirachi!" Nigel exclaimed.

"Looks like I made it just in time!" he cheered. They all looked to see the Massive falling right past them, catching fire as it passed through the atmosphere.

"Aren't you worried where it might crash?" Rachel asked Nigel.

"Don't worry! Just before we left, I was able to set a certain location of where to crash. I get the feeling a certain someone won't be too happy!"

Father's Mansion

Back down on Earth, Father was walking out of his mansion in a rather joyful mood. "Man, what great day it is today!" he said to himself. "You know, I may have been upset when my annoying nephew mysteriously vanished with my pipe, but ever since he left, I've been feeling REALLY good! I don't think ANYTHING can ruin my mood! Not even…" He looked up in the sky with a speechless expression. "A giant, flaming spaceship?" And with that, the Massive crashed into his mansion, resulting in a MASSIVE explosion.

After the fighting was over, Jirachi teleported the gang down to a street on Gallagher, where they were met up with all their screaming and cheering friends. Due to the Massive's explosion, hundreds of Wisps were freed and began flying in the skies of Earth, and thousands of snacks rained down, making children all around the area eager to go and grab the most they can.

"YEAH! NUMBUH 1 DID IT!" cheered Numbuh 2.

"Good on ya, Mate!" Wally exclaimed.

"AYE! What he said!" Marine agreed.

"UNO!" Nigel looked to see Harvey running toward him. The Sector W leader embraced Nigel in a hug with tears in his eyes. "UNO! YOU'RE BACK! I MISSED YOU SO MUCH! PLEASE DON'T LEAVE ME AGAIN! PLEASE!" He then opened his eyes to see everyone was smirking at him. He immediately let go of Uno. "Uh, I mean… Oh, great! Why'd you have to come back, Loser? We were all better off without you!"

"Yeah… sure you were." Nigel replied, not believing him at all.

"YOOOUUU!" They all looked behind them to see an enraged Father. "FIRST, you you break into my mansion, STEAL my pipe, SEND MY DELIGHTFUL CHILDREN TO THE DEPTHS, you disappear MYSTERIOUSLY for three months, AND NOW, YOU COME BACK WITH A GIANT SPACESHIP THAT DESTROYS MY MANSION!" He stomped closer. "WELL, YOU KNOW WHAT, BOY? I AM GOING TO-" He stopped when he heard screaming in the air. He looked up to see the screaming Tallest falling to him. "AAAAAHHHHHHH!" And with that, he was crushed by the weight of the Tallest.

Soon, the smoke from the impact cleared, and the Tallest and Father were standing there, looking dizzy. Father then collapsed and, after a few seconds, the Tallests' armor cracked and shattered, revealing their spineless, wimpy bodies. Just as the Tallests' dizziness was about to wear off, Orbot and Cubot fell from the sky and onto their heads, knocking them out.

Afterwards, the Seven Stars lowered their selves from the sky and circled Jirachi. The Stars came together, making a strong burst of light. When the light cleared, everyone stared agape at the sight of the legendary Star Rod. The Star Rod slowly lowered itself to Nigel and Rachel. Nigel then nodded to Rachel, gesturing for her to take it. She held the Star Rod in her hands and stared at its mysterious glow.

After a few minutes, the Tallest awakened to see everyone staring at them angrily. "N-Now now, kids. I'm sure we can talk this out!" Red stuttered.

Nigel looked behind them and replied, "You may have to talk to them!" The Tallest looked behind and backed up in fear to see an angry Star Wolf glaring at them, namely Rattlesnake Jake. As they slowly approached the Tallest, they heard a mysterious giggle.

"Now now. No need to get so violent. At least… not yet."

"That voice…" Nigel stated. As he suspected, the person who appeared before everyone's eyes was none other than, "Dimentia."

"And so I arrive for my eager audience, waiting for the show to begin!" exclaimed Dimentia. "(And I have GOT to stop talking like my brother.)" Due to her last fight with Eva, her clothes were ripped and tattered.

"Wait a minute: THAT'S Dimentia?" Wally asked.

"Ah was caught off guard, too, Mate." Marine replied.

"UGH! You could really use some make-up or something!" Kuki shouted.

"What are you doing here, Dimentia?" Nigel asked, snidely.

"Yeah, what are you doing here?" Purple repeated.

At this, Dimentia looked to the Tallest, their robots, and the unconscious Father, and simply said, "You know what, these guys have no more significance to the plot, so I'm just gonna toss them aside." She threw a Starburst and knocked them a few feet away. "Anyway, I'm here because THIS is our crowning moment! Isn't it, Jirachi?"

The Star God in question looked confused. "Uh… it is?"

"Well, of course it is! The Star Rod is finally back together! Now we can finally be rid of this disease! Now, Rachel…" She turned to Rachel, still holding the Star Rod, "just hand me that little Star Rod you have there and I'll be on my way."

"No, don't!" Nigel stopped. He then turned to Jirachi. "Listen, Jirachi. Dimentia's been lying to you! There isn't any disease! Dimentia just made all that up, so that you can keep her young!"

"Yeah!" Ava followed. "And she's even been turning all your Wisp friends into monsters!"

At this, Gabe and Jeremy, who had just arrived, gasped. Jirachi seemed even more confused. "…Huh?"

"That's just crazy!" Dimentia replied. "Why would I do anything like that? I told Jirachi and all my fellow operatives nothing but the truth! The only liars here are you! It seems you've been on this planet a little too long, and now you're being brainwashed by the adult mind!"

"Where does she come up with this junk, anyway?" Lizzie shouted. "Heck, she might've suggested I was an alien!"

"We are not the liars!" Nigel argued. "YOU ARE! You have to stop listening to her, Jirachi!"

Jirachi grabbed his now aching head. "I…I DON'T KNOW!"

"We feel your pain too, Jirachi." replied Jeremy.

"If you don't believe us, why don't you watch Nightly News?" Rachel suggested.

"There aren't even any TVs out here!" Dimentia shot back.

"THEN I WISH THERE WAS!"

"NO!"

At Rachel's wish, the Star Rod began to glow, and, before everyone's eyes, a large TV appeared in the air by the side of them. The TV landed on the ground, coincidentally crushing Father and the Tallest. The TV showed an image of Numbuhs 10 and 11.0 on the KNN.

"Welcome back to KNN!" Numbuh 10 spoke. "Today's top story: GKND Leader Numbuh 256 is NOT the leader you thought she was. This footage, given to us by four owls with instruments, explains why." With that, the screen showed the very conversation Dimentia and Nigel had.

"I lied to Jirachi about the disease just so I could use his powers to stay young forever and never have to grow up! As a bonus, I tricked him into thinking the Star Spirits didn't care for him and had him take them out!"

"NO!" Dimentia exclaimed as the clip played a few more times.

"Ooooo, not really the leader I'd ask for." Numbuh 10 said. "You, Kade?"

"Nope. If I were Dimentia, I'd use Jirachi to get rid of my ugly face!" With that, Numbuh 11.0 laughed at his own joke.

"Sssounds like the space-clown was lyin' after all!" Jake hissed.

"You… lied to me?" Jirachi asked, his eyes furrowing.

Dimentia then realized a swarm of Wisps were surrounding her, looking angry. The operatives (plus others) were looking pretty mad, too. "Fine! I admit it! I have been using you for eternal youth! Wouldn't anyone else here do the same? Wouldn't anyone else here want to have eternal youth?"

"Not if it means we have to hurt others!" Rachel argued.

"You tricked me into betraying the Star Spirits! And after all they've done for me." Jirachi said, sadly. "Well, forget it! I'm not letting you use me, anymore!"

"Yeah! You tell her, man!" Numbuh 2 cheered.

"You here that, Dimentia?" Nigel began. "Your reign is officially over!"

"Yeah, so get your ugly, two-faced self off our planet!" Harvey demanded.

"YEAH!" everyone else cheered.

"No." At this, everyone turned to see Mr. and Mrs. Uno on the side. "Dimentia will take the Star Rod and she will use it for whatever reasons she desires." spoke Monty.

"Mr. and Mrs. Uno, how can you say that?" Rachel asked.

"Those aren't my parents!" Nigel yelled. "Those are just some clones Dimentia created to fool everyone!" Everyone gasped. "Dimentia has my real parents trapped below the fountain!"

"Oh, that's preposterous!" Monty replied. "Have you any proof?"

"Here's your proof right here!" said a voice from above. They all looked up to see a spaceship (similar to the one that took Nigel) coming in for a landing. Once it did so, the ship opened, and Maurice, Chad, and Nigel's REAL parents stepped out.

"MAURICE!" Abby exclaimed.

"MOM! DAD! You're okay!" Nigel shouted.

"That's right, old boy! In the flesh! Not like those pathetic excuses for copies!" Monty remarked.

"Now, I say, old chap." replied the Monty clone. "How do we know YOU aren't-" His sentence was cut short when Rattlesnake Jake shot up from behind and stuck his head through his chest, black goo spilling all over as the clone passed out.

"Ain't no humans. Ain't nothin' but phonies!" Just as the Agatha clone was about to escape, Jake dug into her head and killed her as well.

"What ya gonna do now, Freakshow?" Wolf asked.

Dimentia once again looked to see everyone staring angrily at her. "FINE! I'm leaving! But know this: this isn't the last you'll hear of Dimentia Z. Winkiebottom!" With that, she made a box-shaped barrier appear around her. She snapped her fingers and, in an instant, the box made a big explosion. Once the smoke cleared, they all looked to see Dimentia was gone.

"Did she just… kill herself?" Harvey asked.

"Nay. Yon Dimentia is not one to giveth up so easily." Luvbi replied.

"No arguing with that." Kweeb replied.

"Mom, Dad." Nigel began, coming over to his parents. "How did you escape?"

"We have no idea, Dear." his mom answered. "We were just trapped in that dungeon when, suddenly, the entrance opened mysteriously and our shackles were cut loose."

"Regardless, after we escaped, we got back to the base and freed Chad, Maurice, and every other prisoner. We dropped them all off on their home planets just before we came here." Monty followed.

"Well, I guess that's the end of Whatsherface." Wolf figured. He then turned to the Tallest. "Now, where were we?" They approached the Tallest slowly, making them back up in fear. "We got a little motto, bug heads: those who don't pay will be PREY!" At that instant, Jake wrapped himself around them. The Tallest screamed as Jake dragged them through a large smoke cloud from one of the destroyed houses to their doom.

Once they were out of sight, Harvey turned to Luvbi. "So, uh… Luvbi. Now that the invasion's over… you wanna maybe go on a date or something?"

Luvbi smiled. "That wouldst be most pleasant."

"I still can't believe Dimentia was able to trick us for so long." Gabe said.

"I feel so bad." Jirachi stated sadly.

"Oh, don't worry, Jirachi." Infinity replied, putting a hand, er, tentacle on his shoulder. "At least we figured her out before anything bad could happen. Still, putting the Star Rod back in the fountain where she could easily reach it might put us in more danger. We'll have to keep it in a secret location until we're able to catch her. Care to help us, Numbuh 1?"

Nigel looked to see everyone staring at him, awaiting an answer. "No thanks. My place is with my friends. After all, someone has to help fix all the damage the Tallest did."

"YAAAAY!" Everyone gave happy cheers.

Once the cheering stopped, Dib walked over to Zim. "Hey, Zim…"

"Human?"

Dib was silent for a moment and held out his hand. "You're all right." Zim smiled and shook it.

Rachel then looked to see all the destruction the Irkens have caused. "So… should we get started cleaning this up?"

"Ah, we'll take care of that later." Nigel simply stated. "How about we all go to Lime Rickey's to celebrate?"

"Oh! We're coming too!" Orbot replied, finally waking up along with Cubot. Everyone else agreed too and walked off, leaving no one but the still unconscious Father and the mariachi band, playing music.

"And so, Dimentia's cover was exposed and the young bald hero was reunited with his friends. But Dimentia will not face defeat so easily, and our heroes have yet to face their final challenge."

"You know, they could actually wish for everything to be fixed."

"…Yeah, they could, couldn't they? Oh well, let's go to Lime Rickey's!"

GKND H.Q.

Dimentia warped to the secret, dark chamber. "Those fools think they've got me beat, but I won't admit defeat! I already have enough negative energy for my machine! All I need to do now is get back my Star Rod, then Zathura will finally be reborn! Then all those fools will pay…"

Fulbright Household

It was nighttime in Virginia. In the Fulbright Household, Mr. Boss was sleeping cozily in his bed. He was then awakened by the sound of a doorbell and got up grumpily, stomping down to the front door. He finally answered it to see Consuela standing at the door, covered in soot since she never escaped the Massive before it exploded, but was somehow able to survive.

"I need more lemon pledge."

Mr. Boss simply sighed. "Okay." With that, Consuela entered the house as Mr. Boss got in his car and drove to the store.
