"Came along you two." Twilight said, using her magic to carry Doug and Gustavo away. Rarity followed, carrying their equipment and asking them about their costumes. They took turns answering their question and telling their adventure on Monster island, Never Land, meeting Spider-Man, and getting back. They went inside a giant tent, where they saw one of the many giant changelings surrounded by scientists, not breathing tough, and all the other O.C.s were with a scientist and accompanied by a brown stallion with a suit with the "Not bad" rage face as it's mark, all in a sepperate room, protected by a bullet-proof glass window.

"Who is this?" Doug asked

"What's going on?" Gustavo added

"I apologize for this," the scientist answered "it may sound weird, but this stallion is actually the president of the united states."

"It's true," the stallion added "I was busy in my office, when this happened, and the security tried to arrest me for kidnapping myself."

"How'd you get out?" Kane asked

"Many questioning was done. I got all right, and I'm having a hard time to prove to the good people that I am President Obama and to keep all the good people of America calm."

"How's that working?" Robbie asked

"Your friend helped out with the second. Who are you?"

"I'm Robert Meiron."

"Well Robert, you may need to do something amazing like what your friends have been doing, otherwise, you'll end up like that mare over there." Everyone turned and saw Trixie, trying to scramble away from the arms of soldiers as they threw her out the door.

"YOU CAN'T DO THIS TO TRIXIE!!!" Trixie yelled "ONLY TRIXIE CAN DO THIS TO YOU!!!" They threw her out and closed the door.

"But your friend here, I am amazed on how he singe handedly saved the city from blockbuster monster Godzilla!!! No wonder they call him 'The Giant Guardian'!"

"Truth be told," Kane commented "I had help from my friends."

"But you stole the show!!!"

"...I guess that's true."

"What are we here for?" Matt asked

"I'm glad you asked that." Obama said

"Allow me to explain," the scientist said "After your adventures on helping both sides meet face-to-face, we decided to give each other knowledge. We learned the Anatomy & Physiology of the changeling, and found this!!!" He pulled out an X-ray photo of the changeling they're examining, and in the stomach was what seemed to be humans inside."

"They've been eating people!!!" Russell exclaimed

"We thought the same thing, but these creatures, though capable of swallowing a human whole, feed off of love and gives it back to their queen."

"Chrysaliss!" Twilight yelled

"Exactly! But in a different angle, these things are actually growing inside the Changeling's stomach!" Another X-ray picture was shown, providing the saying to be true. "We are going to see if this is what is causing the giants to get cancer: the result of tumors maybe? The only way to know is to look inside this deceased Changeling. They looked and they saw the chest of the Changeling was open A huge black cloud came out, blacking out the whole area with the scientists outside screaming. A figure of the cloud grabbed a scientist, slamming it's head on the window. The figure was a strange Human-Changeling mix! The swarm outside stopped, revealing many of these human-changeling mixes, all of them staring at the box with them in it.

"Who are you?" Obama asked. The Changeling in front dropped the scientist and walked up to the window.

"We are the result of Changelings feeding off Human love." they all said together. "We are an accident that will lead to something even greater. No Earth Pony, unicorn, pegasus, and human being can stop us. Many more of us will come when the one called Chrysaliss continues her plan to make all changelings as giants. Soon, she too will become a giant, and she will become like us, reborn as we were. Only the strongest will lead us all to victory, the rest will be abandoned. She will join, whether through her finding how powerful she can become, or through our force, she will be reborn, painfully, but stronger. There is nothing you can do to stop us, only delay your untimely demise: all other species will be harvested, no longer as what they are, only as a source of food for us, and we will continue, until nothing exists anymore. We are the Alpha and Omega of life, your lives will be meaningless in history. No one will remember you individually, but we will be remembered as a whole in the future. Say good-bye to your last days in life, we will return! This is the end of the Changelings, but the beginning of The Dopplegangers!!!" They all sprouted their wings and flew out, breaking the roof and into the sky, until nothing was left. All stood with their mouths wide open.

"We have to find the cure quickly." Kane just said, breaking the silence. everyone nodded their heads and ran outside, surprised to see some of the other giant changelings bursting and releasing Dopplegangers! They looked at what the changelings could use: NOTHING WAS WORKING!!! Medicines; no good! Massaging changelings; though relaxing, didn't work!!! Having Changeling exercise; SPEED UP THE PROCESS!!! Everyone began to panic: would the Dopplegangers destroy all of Earth % Equestria, becoming the dominant species!?!?!? Robbie ran off and, with truck loads of candy, made both humanoid & ponified soldiers.

"What are you doing!?!?!?" Doug yelled "We are trying to find a cure, and you, are making, CANDY SOLDIERS!?!?!?"

"It's a sacrifice to them." Robbie answered "Or, as I've heard from your adventures, anything can happen!!! They can come alive any second now!... any second now!... It's alive!!! Oh wait... an arm fell off." During their walking, Lywa, the princesses, and the rest of the mane 6 came to them.

"LYWA!!!" Kane yelled, running to her "How are you doing, girl?"

"Fine stwonghart." it answered

"Who is that?" Robbie asked in confusion.

"Sorry," Kane replied "Robbie, meet Lywa; Lwya, Robbie: he's also a human."

"ANOTHER HUMAN!!!" Lywa yelled in excitement, jumping on Robbie's face. Robbie ran around, bumping into objects.

"Alright Lywa, that's enough. You deserve some cereal." Lywa jumped off and went to Kane's leg. Kane found a box of Honey Nut cheerios and made a bowl for the blob-unicorn.

"I'm glad to see you're back!" Matt said, bowing down to both of the princesses

"We are also glad to see your'e also back." Celestia said "And you are aiding the changelings, despite attacking us."

"Createl," Luna said, approaching to Robbie "Who are you and why are you wearing those pants?" Robbie sat there for a bit, staring at Luna, stuttering through his mouth. Without a warning, he fainted, with a baby crib circle of birds 'flying' above his head.

"He's Robbie," Russell answered for the past out Earth pony "and he wears those pants for... fashion? I don't know, he never said so himself."

"Strange, almost as you."

"HEY!!!"

"Please," the scientist said "We have to find a cure for these before more dopplegangers fly out!"

"You're right," Obama said "I don't want to be the last president that destroyed all life on accident!"

"There has to be something we haven't tried yet." Gustavo said "It has to be something weird that, as a sane person, no one would-" before he could finish, Robbie got up and began to sleep walk on his hind legs. He walked over and picked up Lwya's bowl of cereal, who was drinking the milk like a cat, despite there still being cheerios inside.

"MY CEWEAL!!!" Lwya yelled. Robbie threw the cereal at a giant changeling, where it swallowed the bowl whole. The giant changeling got up and was cured!!!

"I'M CURED!!!" The giant changeling yelled "You have saved my life! I am forever in your debt!"

"A bowl of Honey Nut Cheerios was the cure the whole time?" The scientist asked in pure confusion.

"My next guess was Lucky Charms." Pinkie said while dressed up as a leprechaun. Everyone, including the citizens, got together and made bowls for the giant changelings and gave each a regular sized bowl of Honey Nut cheerios. All the giant changelings were cured!!!

Celestia saw the whole army of candy soldiers Robbie made.

"Who made these?" Celestia asked

"Robbie." Doug answered "What a stupid idea, I mean, making a whole army out of candy? It just so crazy-"

"It just might work!!!" Luna interrupted. Both Celestia and Luna casted a spell, as an aura went over all the candy soldiers and going inside the sleep walking Robbie, who was helping out the people for some weird reason.

"What did you do?" Gustavo asked

"Easy: we went inside your friend's mind and pulled out the first person he thought of."

"And that is?" All the candy soldiers started to move and going in an orderly march. They surrounded the walls of Canterlot and held up their candy-cane spears

"NIXON'S BACK!!!" They all yelled "AROOO!!!"

"Richard Nixon?" Matt asked "Is he a fan of Futurama?"

"He is." Kane answered

"That answers that."

"We also saw the Monsters entering here," Celestia said "And this stumbled upon here." Celestia pulled out a remote button and clicked on the remote: the floor rumbled and the floor opened, slowly coming out was Mecha Godzilla!!!

"We have it all under control." Luna stated "Just in case the monsters decide to attack us."

"I beat Godzilla once and I saved him from danger," Kane said "He should know who's in charge."

"True, but do you know how to turn into a giant again?"

"...No... but I bet Discord can help!!!"

"I don't want to" Discord said, appearing in a hawaii outfit.

"WHAT!?!?!?" Everyone yelled

"But Discord!" Kane said in a panicking voice "If I'm a giant, I can save everyone here!"

"True, but you need to do that for yourself. All I can do is this." Discord snapped his fingers. A large dark aura went out of Kane's, Matt's, and Doug's horn.

"What just happened?" Robbie asked, snapping from his sleep

"Rewatch the season 3 premiere." Discord replied "Unless Gak interrupts, then you'll remember. Toodles!" Just as he dissapeared, A large shadow overwhelmed the area. All the Dopplegangers surrounded the sky, along with Queen Chrysaliss, and two giant monsters: A golden three headed dragon and a visor eyed with scythes for arms & a buzzsaw on it's chest.

"Gigan and King Gihdorah!!!" Queen Chrysaliss yelled "Attack and destroy the buildings: leave all the survivors for my new and improved subjects to feed on!" The two monsters roared and landed on the floor, destroying the buildings around them.

"We need to use Mechagodzilla!!!" Russell yelled

"We will do our best to stop them!" The giant Changelings said. The changelings charged at the two monsters.

"Sorry my old subjects," Chrysaliss spoke "Dopplegangers: Attack!!!" The dopplegangers flew down to the ground. Chrysaliss hit them with a spell that caused some of them to grow into giants as well, fighting off the giant changelings as a way to protect the two monsters. The rest landed to search through the destroyed buildings to find survivors of both kinds and drain their love away.

"Nixons!" Doug yelled "Fight off the dopplegnangers!!!"

"I'm not a crook!" The Candy soldiers yelled, charging and fighting othe dopplegangers.

"Doug," Gustavo said "We should put on out 3-D gear and fight off the giant dopplegangers."

"Agreed." Doug said. They both grabbed their equipment from Rarity's magic and put it on quickly, ignoring the unicorn saying how it was rude of them to take it that to ask. With their equipment on, they used the hooks to travel up to the sky, slamming the heads of the dopplegangers about to land with their Sandwich swords. Kane and Matt followed, but helping the giant changelings fighting the giant dopplegangers

"I think you can control this machine." Celestia said. Russell's eyes began to glimmer with hope.

"I agree with my sister," Luna added "This is your thing, we will use our magic to battle the enemy.You control this... Mechagodzilla and fight off the 'Gigan' and 'King Gidorah'. Got it?"

"I do." Russell just said. He flew up and went into the machine's 'mouth', where he found the controls and, with some luck, activated the robot and began to fight the other two giants. Despite fighting two at the same time, he held up pretty well, thank to the robot's ability to fight from behind as well. Robbie stood in complete fear, not knowing what to do with all this happening. He felt a tug on his tail and saw himself being lifted off the ground: Luna was carrying him!

"We may need your assistance." Luna mumbled, still carrying the pants wearing pony

"And please don't faint on us." Celestia added. Robbie was blank faced, not knowing what to do.

Chrysaliss saw what was happening and became furious! Despite being outnumbered, the O.C.'s ridiculous army was actually beating hers!

"I'VE HAD ENOUG OF THIS!!!" She yelled. She aimed her horn at herself and began to grow! Everyone stopped and saw what she was doing: She became a giant herself. Before she could even move, she stumbled and felt a rumble in her stomach, then fell.

"What's happening to me?" Chrysaliss asked

"Just as we've planned." The dopplegangers spoke together "We will have a queen."

"What do you mean? I AM YOUR QUEEN!!!"

"You will pass away, but be reborn as us."

"As a Doppleganger? WHY DIDN'T YOU TELL ME!?!?!?"

"It has begun." Before she could speak, Chrysallis' chest area exploded. A light came from the hole, and the silhouette of a woman was there. It came out: The Dopplegangers were right, she became one of them as they had planned.

"This feels so much better." The new Queen Chrysaliss said "Now, my kingdom can grow!" She sprouted her wings out and began to fly, then released some magic blasts, destroying some candy soldiers & buildings in the process! The magic user's horns began to glow the dark aura.

"what's happening to us?" Kane asked

"I don't know," Matt said "Is it bad?"

"Maybe it's something evil," Doug added "BUT AWESOME!!!"
