Somewhere in a universe in another dimension, a war was happening on the planet of Hopea; and above the planet in a giant spaceship, where the king and queen of the planet watched in horror.
"I can't believe it has come this far," said the king.
"I know Hope, the Master of Darkness has taken this war to far," said the queen with a terrified look.
"You're right Litina, that is why we must call on the five groups that we have been watching," said King Hope as he walked over to a computer and pressed a button. Pictures of the new Sailor Scouts, the new Mew Mews, the new W.I.T.C.H group, the Magic Knights, and Himeno and the Leafe Knights then appeared.
"So it's time to finally bring them in," said Queen Litina. Meanwhile, in Rene's home dimension, Aza and the other seventeen scouts came to the castle for a visit.
"Hey there guys," said Rene as she, Helios, and Seren walked up to the others.
"Seren," said Hara as she ran to the front.
"Hey Hara, it's been a while," Seren as she gave her friend a hug.
"Whoa!" said a voice from the room next to them.
"Hydina, what happened in here?" asked Helios as he and the others walked in and found a blue haired and eyed girl laying on a wet floor wearing a blue tank top and jeans.
"Sorry King Helios, I was just practicing my water manipulation and it got too far out of control," said Hydina as she stud up.
"I take it that you're one of the new scouts?" asked Riy.
"Yes, my name's Hydina H2O, I'm one of the princesses of Hydrina, oh and my Sailor Scout name is Sailor Aqua," said Hydina.
"Nice to meet you; I'm Mairy, Sailor Jupiter, and I was wandering how you used your powers without being in your scout form," said Mairy as she shook Hydina's hand.
"The people of my planet have water based powers from the time they turn eight, but since I'm a Sailor Scout my powers are stronger than normal," said Hydina as she took a rag from a maid and begun to clean up her mess.
"She's even stronger when she's transformed," said Seren as she helped Hydina.
"So you're here to practice with less gravity than what is on your planet?" asked Salyn.
"Actually my planet is pure water, and it has less gravity than any moon," said Hydina as she stud up to ring the rag out into a vase.
"Cool," said Daytrex.
"Hey guys, you might want to look at our feet," said Saga. When the others looked down, they saw that they were starting to vanish.
"What's happening?!" asked JunJun with a worried expression.
"I think we're being transported somewhere," said Aza as all twenty-one of the scouts vanished into thin air. When they reappeared, they were in a large white room on King Hope's spaceship.
"Where are we?" asked PallaPalla.
"I'm sorry about forcibly taking you, but it was the only way to get ahold of you," said King Hope as he walked into the room.
"Who are you and why have you brought us here?" asked Daisy who looked like she might start throwing punches.
"I'm sorry, my name is Hope, king of the planet Hopea, and the reason that I have brought you here is that I need the help of your group and the four others," said King Hope as he bowed to Rene.
"What other groups?" asked Rene.
"How about I introduce you, they are in our conference room," said King Hope. He then led them into the room that he had come from, and Rene and the others were surprised to see four other groups already there.
"So you're the final group?" asked Tori Aizawa from the Mew Mews as she stud with her group.
"You're the Sailor, what was it again?" asked a small girl riding a big ball.
"First off, it's Sailor Scouts, and second, I thought we told you to only ride that at the café, Sara," said Neko Momomiya.
"It's not my fault that I was on it when we were transported here," said Sara as she did a back flip off the ball.
"They sure do have young worriers in some other dimensions," said Hayate.
"Be nice Hayate, and don't forget that we have some young warriors too," said Himeno as she held his hand.
"What a cute couple," said Hikari Olsen as she talked to her W.I.T.C.H group.
"Some of these people make you look older," said Umi from the Magic Knights as she looked at Hitaru.
"I know right?" said Hitaru with a smile.
"Alright everyone, let's get down to businesses," said Queen Litina.
