Somewhere in the forest, a yellow star like creature was flying around, desperately trying to find the heroes of the Mushroom Kingdom. They last met when Antasma tried to take over Pi'illo Island. Something has been going on down in the Abandoned Underground Pipe Mazes, and she needs to find the brothers once again, and find out what's going on.
"I can't find them anywhere! They shouldn't be far from here. I wouldn't be surprised if Luigi is hiding in a bush somewhere. Mariooo! Where are you??!"
Peach gasped in surprise. The last time she heard that voice felt like forever.
"That voice. Is it who I think it is?"
The yellow star creature named Starlow, finally managed to find the group. She needed to tell them the news urgently, but quickly discovered there were unknown guests.
"I finally found you! I have urgent news and---who are all you guys?"
Pinkie Pie bounces up and explains to Starlow everything that has happened up to this point, and that they are all from different worlds.
Starlow tried to piece together all of what Pinkie said.
"So you're all from different worlds? And you have to find these Elements of Harmony because you think those are essential?"
Pinkie smiled in glee.
"Yep. That's just about it!"
Isabelle pulled out one of the Chaos Emeralds they have.
"We've also found these large glowing diamonds. I'm not sure what these are, but they've helped us out so far."
Peach wanted to know why Starlow needed to see them so urgently.
"So, Starlow, why did you come all the way here?"
"I went to see if I could find Mario because apparently there has been strange activities happening in the Abandoned Underground Pipe Mazes."
Peach rubbed her forehead in confusion.
"But the Pipe Mazes have been sealed off for years. I made sure the guards sealed off any traces of it."
Starlow frowned.
"That's what really bugs me. Someone, somehow found a way in."
Starlow flew next to Isabelle, wanting to have a closer look at the Emerald.
"Isabelle, may I see that glowing diamond?"
Pinkie bounced up to the 2.
"You can borrow mine if you want!"
Starlow closed her eyes in thought, trying to figure out what these gemstones could be.
"I'm calling it a hunch, but maybe these diamonds are somehow connected to what's happening underground. I could sense some weird energy readings that seem to match the ones of those diamonds. I think, if we find the source, we'll find whoever's causing all these earthquakes before matters get worse."
Applejack stepped forward with a determined look on her face.
"So ah say we go there and stop whoever's causin' all this!"
Mario & Luigi jumped in excitement, ready for another adventure.
"Let's-a go!"
The group made their way to the Underground Pipe Mazes.
"Here we are. Since the earthquakes are coming from here, my guess is to watch out for any falling debris."
"Apple Bloom, you and your friends stay outside. Ah don't want you getting into any trouble."
Apple Bloom frowned at her big sister, wanting to come along and help.
"But Applejack, we can help."
AJ frowned and hugged her sister.
"Sorry, but ah don't know what ah'd do if anything happened to you. Isabelle, you stay here and make sure these young fillies behave."
"But what if Mayor needs my help?"
Peach giggled before telling Isabelle that he'd be fine with them.
"Don't worry, Isabelle, he'll be fine with us."
Scootaloo was a little bit frustrated. The filly really wanted to join the others inside that place.
"How come he gets to go with you but we don't?"
Scootaloo frowned in dissapointment.
"You saw the way he handled that Koopa Kid. He can help."
The CMC grudgingly accepted. Isabelle asked Villager if this would be okay.
"Mayor, is it okay with you?"
Villager nodded, telling her yes.
"Okay!"
"Don't worry about us. We'll be back before you know it."
Applejack told the others so they had less of a reason to worry. Isabelle and the CMC wished them good luck.
"Be safe!"
The rest of the group are now inside the cave. As expected, it is incredibly dark down in here. Pinkie seemed to be the first to notice.
"It sure is dark in here."
Starlow saw glimpses of previously lit lanterns through the darkness.
"There used to be lanterns all over the place, but they seemed to have died out."
Luigi pulls out his flashlight. It's the same one he's used to help E. Gadd with his ghost problems. Peach's face lit up.
"Good thinking, Luigi! This is much better now."
Suddenly the ground started rumbling, making everyone wobble and almost lose their balance. Starlow flew over to where she felt that shaking came from.
"Looks like we're getting close. I can hear footsteps over there."
"Ah think ah see a door."
Starlow inspected the door with a frown. Something wasn't right. This wasn't here the last time she went to this place.
"That's strange. This was never here before, and there seems to be a logo on it. Does anyone know a "Dr. W"?"
Pinkie instantly jumped up and put her hoof into the air.
"Ooh! Ooh! I know!"
Applejack shook her head.
"Pinkie, we don't have time for your little guessing games. Let's just open the door."
The door suddenly opened by itself, surprising the group. A figure appeared, but the group couldn't make out who it was.
"Well well, it seems we have a visitor!"
Starlow, who had turned away from the door, instantly turned back to see who was present among them.
"Who said that?"
"I never thought I expected to see you here, Me---wait. You're not...It doesn't matter. What does matter is that you won't live to tell anyone about this! Guts Man, ATTACK!"
Out of nowhere, something came crashing down from the ceiling, making rocks fly everywhere. Thankfully, nobody was hurt. Pinkie saw the creature that caused the wreckage, and had no idea what it was.
"What is THAT thing?"
AJ gave it a quick thought.
"It looks like some kinda machine."
Guts Man jumps up, causing an earthquake. Then a boulder lands in his hand.
The ground started shaking once again, making everyone wobble once again. Peach, being the gentle soul that she is, wanted to make sure everyone was okay.
"Is everyone alright?"
Applejack got ready for an attack by the robot.
"Don't look now, but somethin' tells me that machine's gonna throw that boulder at us."
Peach ran to the door wanting to escape.
"Let's get out of here!"
The door slammed shut, leaving them stuck inside the cave.
"The door won't open! We're trapped!"
A bomb suddenly appeared next to the robot.
"Where'd that bomb come from?"
"Everyone, duck and cover!"
As soon as Starlow said this, everybody ducked under the fallen rocks to save themselves.
BOOM!! The mysterious figure, now perfectly viewable as some kind of scientist, was outraged! His robot had been completely destroyed. Though none of them knew who this person was.
"What? NO! Not my Guts Man copy! I don't know how you managed to find out his weakness, but you'll pay for this!"
The mysterious madman jumped into his ship, flying out of the cave and from the group.
Pinkie stood there with a confused look on her face.
"Who was that guy anyway? And who saved us?"
Suddenly a beam of light appears and a blue robot emerges from it.
"Another one down! I'm not sure how Dr. Wily managed to get here, but good thing I followed him."
The robot turned around and noticed the others.
"Who are you? Are you working for Dr. Wily?"
He put his arm cannon out, ready to fire. Starlow quickly told him that they weren't evil out of panic.
"Wait, don't shoot! We're friendly."
"Come to think of it, my sensors do say you're all organic."
Starlow flew towards the blue robot, feeling safe that he won't attack.
"That bomb that stopped that other robot, did you do that?"
"Of course. I didn't want to but I had no choice."
The robot spoke through an intercom on his arm.
"Dr. Light, I've defeated the Guts Man clone, but I seem to have found people here."
"Excellent work, Rock. Dr. Wily's on the move again so I suggest you follow him to his next location."
"Got it."
He then proceeded to turn off the intercom.
"Now then, I think we should get out of here."
Back at the entrance of the cave, the Cutie Mark Crusaders were telling Isabelle about some of the crazy things they've done, in order to get their cutie marks.
"...and that's when we all realized we should never force people to fall in love with each other."
"Wow, you three have been in quite a few situations, haven't you?"
The group, including Villager, walked out of the cave unscathed.
"Mayor, you're okay! What happened down there?"
Pinkie Pie, unsurprisingly, instantly jumped up and explained everything.
"First, we were underground, then there was this huge earthquake and it made us all shake up and stuff, then we found this weird old guy in a flying thingy that made the most droning sound ever, I mean how can anypony listen to that? It's so annoying. So then he says "You're not telling anypony what you saw" and sends out this yellow and black robot. It threw boulders at us and we were all "help! what do we do?", then suddenly a bomb appeared out of nowhere and the yellow and black robot just exploded. Then the old guy left and suddenly this blue robot appeared and it turns out he saved us and now here we are!"
Isabelle stood there surprised.
"Wow, that sounds like quite an event."
Starlow flew next to the robot.
"I almost forgot, thanks for saving us back there. We never got your name by the way."
"I'm Rock. I was just a cleaning robot created by Dr. Light. But I was converted into a fighting robot to save the world known as
Mega Man!"
