One day, three mysterious women from the Diamond Clan visited the Rainbooms.
Adagio Dazzle, their leader, tells them a legend.
"Our ancestors had spiritual powers that allowed them to defeat the menacing evil spirits. Our clan and the Pearl Clan fought against evil together. But one day, someone very powerful appeared in the Pearl Clan and, using his power for evil, he allied with the Evil One to dominate the world" Adagio explained "However, the Diamond and Pearl Clans joined forces to fight. In the end, they locked the Evil One in a ceramic statue".
At that time, Agadio explained the current situation.
"Now, the Pearl Clan wants the two diamonds from the statue and use them to free the Evil One. We managed to take one of them and escaped, but accidentally I dropped it and you found it" Adagio said, before pointing at Twilight "So, Twilight... where's the diamond? Give it back to us".
"I had it..." Twilight said, with a nervous smile "But not anymore".
"WHAT!?" the three women shouted "WHAT DO YOU MEAN YOU DON'T HAVE IT ANYMORE!?"
At that moment, being scared, Twilight remembered something.
"Flurry Heart..." Twilight said "Flurry Heart has it!"
Then, they all started searching the room of Twilight's niece, Flurry Heart.
"I've looked everywhere for him, but... he wasn't there!" Rainbow Dash said, after searching the room.
At that moment, Flurry let out a small burp, causing everyone to look at her in fear.
"It can't be..." Fluttershy said.
"Don't tell me..." Rarity said.
"Flurry…" Sunset said.
"She has eaten the diamond!?" Twilight said.
And when Flurry giggled, everyone was alarmed.
"WHAAAAAT!?" all yelled at the same time.
Movie 5:
SEARCHING FOR THE LOST DIAMONDS
"The Pearl Clan will come for Flurry Heart" Adagio said "We must flee the city!"
"Come on, girls" Twilight said "We have to protect Flurry Heart!"
"YES!" the Rainbooms yelled.
The Diamond Clan members protected the Rainbooms and Flurry Heart, leading them all to Diamond Mountain.
But what they didn't know was that in the Pearl Clan, there was Tempest Shadow, a woman capable of reading the minds of her opponents.
They all protected Flurry Heart with all their might, but Tempest was stronger, leaving only Twilight.
"I will not let you lay a finger on my niece!!" Twilight yelled "TAKE THIS!!"
Twilight tried to punch Tempest, but she blocked it just fine.
"I read your mind" said Tempest "Game over, girl"
And then, in one quick move, Tempest knocked Twilight unconscious and kidnapped Flurry Heart.
The next day, the Rainbooms made a decision: in order to save Flurry Heart, they would all go to the Pearl Clan headquarters... where they were preparing to awaken the Evil One!
There, Bulk Biceps, the bodyguard of the Pearl Clan, had been in charge of taking care of Flurry Heart.
He got along very well with her and decided to side with the Rainbooms.
However, the diamond had already come out of Flurry Heart's body.
Everyone rushed to prevent the resurgence of the Evil One.
But at the top of the tower, Tempest was waiting for them, with the statue of the Evil One in her hands.
"If you want to save this corrupted world so much..." Tempest said, ready to fight "First you must defeat me!"
"But, that's impossible" Fluttershy said "She reads our minds to dodge our attacks!"
"We'll distract her!" said Adagio, who was ready to fight together with her companions and Bulk "You guys think how to defeat her, Rainbooms!"
In the midst of the battle, the Rainbooms discovered that the only way to defeat Tempest... was by singing.
Together... the Rainbooms began to sing.
With their song, the Rainbooms blanked his mind, managing to defeat Tempest.
But then, something VERY bad happened…
Flurry Heart had put the diamonds in the statue, awakening the Evil One!
"Who has called me?" said the Evil One with a threatening voice "And for what reason?"
"It was me!" Tempest yelled, recovered from the fight "Because I want you to help me!"
But then...
"Once again the same story, this is incredible..." the Evil One said, approaching Tempest "You are the living image of the woman who centuries ago made me conquer the world"
"Wait a minute... the Evil One is..." Pinkie said, deducing the reason for the Evil One's attitude "A transvestite!?"
"If your balls were taken away for over a thousand years, you'd also crossdress, okay, know-it-all?" the Evil One said to Pinkie.
Then, the Malgino headed back towards Tempest.
"Listen pretty, I'm sorry I can't do anything for you, but I'm expired" the Evil One said "Now I am nothing more than a simple transvestite, it feels like it!"
In the end, the police took Tempest and the Pearl Clan members away for their crimes, while the Evil One and Bulk Biceps went to live with Adagio and the Diamond Clan.
"We've been on the verge of death..." Applejack said, surprised by the situation "For this!?".
"Why so much suffering...?" said Rarity.
And when the Rainbooms returned to Canterlot City, everything was back to normal.
