Note: Since it's spring break in my place, there's a chance I can now update everyday.

After getting back to Ponyville, Twilight brought her friends back to Canterlot. "We've found one of Gems of Light," said Twilight. "That's great news," said Celestia. "Your majesty," said Finn, "Some of our friends were wounded in a battle with one of Xanazor's minions," he said. "Will they be fine?" asked Celestia with a little concern. "Lorina said that the spider's venom wears off in a few hours and it took us some time to get back," said Finn.

Celestia gave a sigh of relief that they weren't harmed after all.

Then, Lorina appeared on the disk and said to Finn, "I am receiving a message from your home dimension."

"Open it up," ordered Finn.

Lorina did so and her figure disappeared and in it appeared a holographic projection of Princess Bubblegum. "PB," said Finn looking at the hologram. "Finn," said Princess Bubblegum with concern, "We are being attacked by a strange creature and we need your help," she said. "Is it one of Xanazor's mechbeasts?" asked Finn. "I believe so," replied Princess Bubblegum. "We'll come," said Finn, "And I made some new friends while I was searching for the Gem," said Finn. "Okay, but some quickly," she said urgently, and then the message ended.

"Celestia," said Finn, "I have to go back to my home dimension to fend off some of Xanazor's minions and can you send our friends over once they've recovered?" he asked while putting the bodies of their friends in front of her. "I will try and heal them while they are here," replied Celestia. "And take the Elements of Harmony with you," she said as she went and took it to give to Twilight Sparkle.

"Great," said Finn, "Now let's go," he said to the ponies and Spike. "So how will we get there?" asked Rainbow Dash. "You forgot that I have a dimension traveling device," said Finn. "Oh," said Rainbow Dash. "Now, in order for it to transport all of us, we need to be close together," he said. The Mane Six and Spike all walked close to Finn. "Now Ooo, here we come!" he shouted as he put the device settings to Ooo and pressed the knob. Then, in a bright flash of light, the six were all gone.

Ooo,

A flash of light appeared and Finn, Twilight Sparkle, Applejack, Rarity, Rainbow Dash, and Spike stood at the spot. "You live here?" asked Applejack bewildered. "No, I live in the Tree Fort which isn't very far from here and it feels so good to be back in my home dimension," said Finn.

"This entire place is made out of candy and it looks pretty," commented Rarity. "Pinkie Pie would definitely love this place," said Rainbow Dash.

But their conversation was cut short when they heard explosions and turned to see fire and smoke in the distance. Then, a ball hopped up and spread out to reveal some kind of robot which had eight red eyes and it had guns instead of hands. "So that's the mechbeast that Princess Bubblegum was talking about," said Finn.

The mechbeast turned and fired several shots at the six of them but luckily, they dodged in time. But as the blasts headed, they split up into separate blasts in a circle-like formation and blew up a building behind them.

Then, Lorina appeared in her disk and said, "That mechbeast fires scattershots, scattershots scatter into separate blasts moments before their impact, hence their name and they are dangerous." "Thanks for the info, Lorina," said Finn. "I am receiving another message," said Lorina as her projection form changed and in her place stood another projection of Princess Bubblegum. "Also," she said, "If you do defeat the mechbeast attacking the Candy Kingdom, go and help the group I sent to find the Gem of Light in Ooo, in case they are being attacked," she said with some concern. "We'll do it, PB," said Finn. Then the holographic message ended.

"So how do we defeat this thing?" asked Rainbow Dash to Finn. "I don't know," said Finn. "Wait!" he suddenly said.

"What?" asked Twilight.

"Can you use your unicorn magic as a shield?" asked Finn. "Sure, why?" said Twilight. "Hopefully, it will protect me from its blasts," said Finn. "Are you sure about this, sugarcube?" asked Applejack. "You'll see," said Finn.

Then, Twilight Sparkle focused all her magic on created a force field surrounding Finn while he ran towards the mechbeast, pulling out his sword.

The mechbeast noticed Finn coming and fired several scattershots at Finn but he kept on running and those blasts were strong enough to cause cracks in the force field.

Just before the force field cracked completely from all the blasts, Finn jumped on its head and began stabbing it while it tried various ways to shake off Finn.

Finally, it aimed one of its guns at where Finn was standing on it and fired but luckily, Finn jumped off just as they became scattershots and hit the mechbeast, destroying it. "That was easy," said Rainbow Dash.

"Lorina," said Finn to the disk, "I'd like to talk to Princess Bubblegum," he said. Then, Lorina's disk brought out a holographic projection of Princess Bubblegum. "Bubblegum, so where is that search group that you sent to get the Gem of Light in Ooo?" asked Finn. "They are somewhere in the mountains where the Gem is located and Lorina can track them down," said Bubblegum. "How do we get there that quickly?" asked Finn. "I've already sent Lady Rainicorn to help you," she said before turning off.

"Who's Lady Rainicorn?" asked Twilight. "Jake's girlfriend," whispered Finn. "What does she look like," she asked.

"Like a unicorn except she has a very long body and lots of Rainbow colors," said Finn.

At that moment, Lady Rainicorn suddenly flew by and landed in front of them. "Whoaaaa," all of the ponies and Spike said, looking at her. "She has rainbow colors just like me but it's all over her body," commented Rainbow Dash. "All rainicorns are like that," said Finn. Lady Rainicorn also looked with some surprise at the ponies and the tiny dragon that accompanied Finn. "Let's ride," said Finn as he and the ponies and Spike except for Rainbow Dash climbed onto Lady Rainicorn and they flew off.

---

In the skies, Lady Rainicorn, carrying Finn, Twilight Sparkle, Rarity, Applejack, and Spike with Rainbow Dash flying besides her all headed toward the mountains at a fast rate.

To Rainbow Dash, she had to admit that Lady Rainicorn was fast but not as fast as her.

"Are we there yet?" asked Twilight Sparkle. "Almost," said Finn looking at the location tracker.

Later, as they flew farther, and finally reached the mountains, Finn said, "We're there," "Finally," said Rarity as she and the others got off. "So where next?" asked Twilight. "According to my sensors, they are in that cave," said Lorina as she appeared on the disk again. "Then let's go," said Finn to them and they ran into the cave.

Meanwhile, on the other side of the cave, Marceline, Flame Princess and a few banana guards in the search group were being attacked by a large scorpion mechbeast. The mechbeast had killed most of the banana guards.

Marceline swung at the mechbeast with her axe bass but it blocked the repeated attacks with its pincers and released and attacked. Marceline dodged in time, and it only grazed her. Flame Princess shot blast after blast at the mechbeast but it blocked with its pincers and stabbed with its giant tail. Flame Princess instantly fell to the ground after the attack, injured. Marceline continued her duel with the creature, making attacks and dodging its attacks.

Then, while she was still hitting it, the scorpion mechbeast lashed out its tail very fast and stung her and she fell to the ground.

As it was going to finish her off, suddenly it heard something. "Leave her alone!" shouted Finn as he and the group got to the place. "Finn, you're here? I thought you were in some other world searching for a Gem Of Light," asked Marceline. "We came back to protect you," said Finn. "Who are them," asked Marceline pointing to Twilight Sparkle, Rarity, Applejack, Rainbow Dash, and Spike. "Some friends I made on the journey," said Finn.

Then, he noticed Flame Princess's body on the ground and grew angry. "Now let's finish it," shouted Finn to his friends.

Finn jumped, pulling out his sword and made the first attack at the scorpion mechbeast and slashed savagely. The mechbeast continued to walk back as it was trying to block all of them and just when Finn was about to bring his sword on the mechbeast's head, one of the mechbeast's pincers caught it. He pulled with all his might but couldn't pull his sword free and then the scorpion lashed out its tail at Finn and knocked him with the sword to the ground. "Are you okay, Finn?" asked Twilight Sparkle. "Yes," said Finn, trying to get back to his feet, "Don't mind me for now," said Finn, "Go stop the mechbeast."

They did as they were told and went. Twilight and Rarity levitated as many rocks they could find in the cave and tossed them at the mechbeast but they only bounced off and fell to the floor.

"Take this," said Rainbow Dash as she charged at it but it responded by attempting to attack her with its pincers and she dodged just in time. Spike spat fireball after fireball at the mechbeast and it seemed to do some damage but stopped as soon as the mechbeast lashed out its tail at him. "Look out," said Twilight as she levitated Spike away just before the tail hit the spot where he was standing at.

"How do we beat that thing?" asked Applejack urgently. Twilight looked up and saw several stalactites at the top. "I've got an idea." said Twilight. "Well, what is it?" asked Rainbow Dash. "You see the sharp rocks on the top?" asked Twilight. "Yeah," said Rainbow Dash.

"I need you and the others to destroy them so they will fall on the mechbeast and hopefully destroy it," said Twilight Sparkle.

"Okay," said Rainbow Dash.

Twilight told the others her plan and then she and Rarity focused their unicorn magic on pulling the stalactites from the ceiling while Rainbow Dash was ramming them as hard as she could and Applejack was bucking the wall.

Eventually, all that racket caused the stalactites to fall and they crushed the scorpion mechbeast.

"We won," said Twilight Sparkle.

"Turns out the guys could do more than I expected," said Marceline. Then, Flame Princess was getting up and some surviving Bannana Guards came out as well. At the moment, there was a huge flash of light and then, Jake, Fluttershy, and Pinkie Pie appeared at the site of the flash. The ponies hugged each other at being together again while Jake walked to Finn and said, "What did I miss?" "Defeating two mechbeasts," said Finn. "So how did it go?" asked Finn to Jake. "The princess said that even with her power, the venom is very strong," said Jake. Then, Finn turned to the group."Let's find the Gem together," he said. And they set out again.

As the large group was walking, the ponies were getting along really well with Marceline and Flame Princess. "So you're made of fire? That's very cool," commented Rainbow Dash on Flame Princess. "Yes, but sometimes I may destroy what I touch," she said. "She's got a fiery personality," said Finn to Rainbow Dash.

"We're almost there," said Marceline looking at that scanner that Princess Bubblegum gave her.

After walking a little longer, Finn looked at the scanner and said, "The next step and we're there." But just as he finished saying it, a group of Kronosian warriors, Kronosian elite warriors, Kronosian wolves, and Kronosian Alpha Wolves suddenly appeared in front of them. "Oh crud," said Finn as he saw them.

The Kronosians attacked and the Banana Guards were able to hold some off but got cut down while Finn sliced through Kronosian after Kronosian and Jake pummeled Kronosians and Rainbow Dash and Applejack bucked some Kronosians away and Twilight and Rarity slammed apart Kronosians with their unicorn magic while Flame Princess blasted apart Kronosians with her fiery blasts and Marceline sliced apart some with her axe bass and Pinkie Pie fired her party cannon slamming some into the walls of the cave.

After a while, the group had defeated the Kronosians sent to attack them. "Ha! Is this the best you've got Xanazor?" taunted Finn. "Why are you shouting up there, sugarsube? There's no one there," asked Applejack. "I don't care," said Finn.

Then, they continued on and saw a large cavern with a luminous yellow glow. "That's it!" said Finn as he saw the Yellow Gem of Light. But as he reached to go get it, a red flash of light appeared behind the Yellow Gem of Light. When the red flash of light cleared, all of them saw Queen Chrysalis. "Queen Chrysalis?!" gasped the Mane six. "Yes," she said, "And I will take this so called 'Gem of Light'," she said as the levitated it towards her. "No!" shouted Finn as he leapt and attacked her, but she blasted him to the ground with a shot from her horn. "Weakling," she muttered.

"Who is that?" asked Marceline to Twilight Sparkle. "She's Queen Chrysalis the Changeling Queen, and she once tried to take over Canterlot and feed by disguising as Princess Cadence and being in the wedding so she could feed off the love and take over Equestria," said Twilight. "And she can also shapeshift," added Twilight.

The group rushed into battle against the Changeling Queen and when she saw them arrive, she said, "You don't have enough power to beat me," and fired blasts from her horn. They dodged and Rainbow Dash charged directly at her, shouting, "Take this, bug!" but got knocked out by her horn's magic. Pinkie Pie fired her party cannon at Queen Chrysalis but she simply moved aside and said, "Is this the best you've got?" But she was then immediately hit by a fire blast and she looked to see that her attacker was Flame Princess. As she prepared to charge her horn to fire at Flame Princess, she got punched into the cavern wall. Queen Chrysalis looked up from her spot to see that it was Jake.

"Not you again!" she said with anger, lighting up her horn. Then, several Changelings appeared and attacked them.

"Take these!" shouted Finn as he sliced through Changelings. While Finn was hitting Changelings with his sword, Twilight and Rarity were blasting some with their unicorn magic and Jake stretched into his large form and punched aside large numbers of them but just as he punched aside all that were attacking him, he didn't expect Queen Chrysalis charging at him.

Jake fell to the ground, injured.

Rainbow Dash charged several of the Changelings while Applejack bucked several that came near her and Fluttershy used her Stare at some that dared to attack her and Spike, shot fireballs at the Changelings.

While they were all fighting, Finn asked Lorina, "So what can one Gem do to a person?" "Provide them with great power," said Lorina "but they are still vulnerable and after they are used, must recharge for a while," she warned.

After listening to Lorina, Finn pulled out the Red Gem of Light and then it floated out of his hands and spread and energy aura around him. Finn began glowing and the energy even reshaped his sword. Everyone ceased their attacks to look with wonder at Finn. "What's happening to you?" asked Twilight, looking at Finn. "I think it's giving me its power," said Finn. "No," said Queen Chrysalis with some fear on her face. "Time to say goodbye, bug queen!" said Finn as he released a large blast and it blasted off the top of the cavern ceiling and the walls and sent Queen Chrysalis and her Changelings flying. "How could this have happened again?" she shouted as she flew into the distance.

"You could do all of that with just one?" asked Rainbow Dash. "Yeah, and I can imagine how powerful we can be if we have all of them combined plus the Elements of Harmony and another energy source," said Finn. "Then what in the hay are we waiting for," said Applejack, "Let's go to the next dimension," she said.

Finn powered down to normal and he and Jake and the ponies and Spike all gathered together and Finn said to Flame Princess and Marceline, "Bye." "Bye," they both waved back.

"Now let's head to the nearest dimension," said Finn. "Mobius," he said as he turned the dial to Mobius and pushed the knob and all nine of them were gone in a flash of light.
