As Byleth walked throughout the Legacy, he was at least glad there were built-in portals on this floating city. He held tight to the device he brought back from the Mysterious Dimension, taking a good look at the object. He started to recall the events ten years ago, back to when Galeem destroyed his universe.


Peace had just been declared in the three main nations of Fódlan once again. There were crowds of people rejoicing in front of the Monastery, with Byleth standing next to his three best students: Claude of the Golden Deer, Dimitri of the Blue Lions, and Edelgard of the Black Eagles. The sun was shining bright in the sky, its beams glistening through the stained-glass windows in the Garreg Mach Monastery. There was going to be a banquet and dance planned within the academy, with all of his students helping out with the preparations. Everything was going to be great.

That was… until the light turned against the three nations.

Beams of light brightened the sky, burning away everyone Byleth saw. He tried to make his students evacuate the school, but in the end, they just pushed him away to safety.

"Save yourself!" they called out individually before they were consumed by the light. "You need to flee this planet!" The moment Byleth stepped out of the school, he was almost eaten by a beam of light before a flash in the shape of the Crest of Flames appeared right in front of him, deflecting the light beam. Sothis was standing in front of the professor, coating his body in a divine aura with her powers.

"If there's anyone that's gonna save you, it's me!" Sothis snapped, taking notice of the beams of light curving towards them. "You're our last hope on this world! Wherever you're going, it's getting the hell away from here and taking you to safety!" The last thing Byleth remembered was Sothis's powers warping him off the continent, taking him away from the beams of light.


When Byleth woke up, he struggled to get up from the cold, hard ground. He looked to his side and saw the Failnaught, Aymr, and Areadbhar. But why would the goddess he was forever bound to in spirit give him these weapons? They only worked for Claude, Edelgard, and Dimitri respectably. To wield weapons that only work for descendants of certain Crests is a dangerous one indeed, but not as dangerous as the world he was now trapped in. Without another thought, Byleth picked up the weapons and walked through the new landscape.

The landscape was barren, with hardly any plants in sight among the jagged rocks. There were strange colors dancing around, their echoes ringing throughout the area. They sounded like cries of help, pleading out to any survivors to restore their bodies. They wanted to escape this planet.

Byleth kept walking until he stopped at a cliffside, shocked by what happened to the landscape. It felt rather alien-like, and there were locations parts of different moments in history, ranging from the prehistoric ages to the far future. All of a sudden, Byleth heard the sound of a branch snap, and he quickly pulled out the Sword of the Creator. With a flick of a wrist, he lashed his weapon at the intruder. The stranger jumped into the air and quickly pulled out a gun, shooting at the professor.

Byleth used the Failnaught and aimed it at the masked stranger, to which the weapon worked for him surprisingly. However, since he had no idea how to use it, he shot right at a nearby rock, revealing an opponent wearing a red cap and vest.

The stranger charged at both Byleth and his opponent, rising high into the air with a powerful dunk. However, pieces of rock flew around when he missed and landed, and one of the rocks hit a bipedal bear in the head at high speed. The bear survived, and he quickly pulled out a bird from his backpack. The bird was willing to assist the bear, and she quickly coughed out a barrage of blue-shelled eggs at Byleth and the two strangers. A fifth challenger arrived late to the party, and he pulled his sword out upon encountering the other four. Soon enough, all the five opponents (Byleth included) were pointing their weapons at each other… with the bear holding his bird partner like a shotgun. However, the one who brought chi and fists into the fight stepped between the challengers.

"Woah woah woah!" the stranger spoke. "I don't know if it's too late, but… I'm Terry Bogard. I just want all of you guys to put down your weapons and just… think about what we're doing here. I mean, I didn't channel all the chi of the earth just to blast off into space and wake up on some planet of unknown origin. We're not just gonna attack each other over nothing if we can't figure out why we're here. So… let's just calm down and see what's the problem." The fighters put down their weapons, slowly starting to understand what they're doing here.

"I'm Byleth," the professor introduced himself. "And you must be…?"

"Ren Amamiya, but my codename's Joker," one of the strangers answered.

"My adopted name's Ireburn, but my royal name's Eleven," another responded.

"I'm Banjo, and this is my best friend Kazooie!" the bipedal bear called out. It wasn't long before the other fighters began to talk about their history and what they had in common with each other before going into how they got here.

"The goddess Sothis used whatever powers she had left and saved me from burning in light along with my continent," Byleth spoke. "Those deadly beams were unavoidable and ate everything."

"A similar situation happened on Earth," Joker noted. "Well… MY Earth, since we're from different universes. The beams of light you described? An attack just like that harmed both the real world and the Metaverse. Arsene commanded all the Personas I had to warp me out of there, draining their powers in the process. By five years, Arsene would be the only Persona I have access to."

"Somethin' strange also happened in my land," Banjo replied. "The sky was bright, everyone was crying and burning into ashes. I hid underground thanks to our mole buddy Bottles and he was eaten by the light like the others. The Lord of Games, or L.O.G. for short, answered on one of Bottles' contraptions and told me to use a machine and warp Kazooie and me outta there."

"I used my magic powers to escape," the Hero pointed out. "…Just thought I'd like to point it out."

"So… we're all here because of one reason: all our worlds have been devoured by light, and we need to get them back and return home," Byleth spoke with a bit of surprise in his tone.

"But how do we do that?" Terry asked.

"By finding the source, or course," Joker answered. "But first we're going to need to explore this world, see what we can find."


Sometime later, the survivors have been walking through a thick forest until they stumbled across a large blooming flower in the center of a garden. The flower began to quickly move around, twisting and turning until it became some sort of carnivorous plant. The plant didn't attack the fighters, and it simply looked at them like a newborn to its mother.

"Woah… hey there, little guy," Terry spoke, holding his hand out to the mysterious plant. The creature didn't attack, but it simply sniffed the Legendary Wolf's hand and licked it. The fighters could see that the plant had teeth, which was not like any other plant they had seen.

"Looks like a Piranha Plant from the Mushroom Kingdom," Banjo spoke. "But what's that thing doing here?"

"Don't know," Kazooie responded. "It doesn't look hostile, from what we learned."

"Does anybody have a flower pot?" Terry asked, rubbing the Piranha Plant's head like a dog. "Looks like he wants to come with us." Eleven looked around the garden until he found a flower pot, by which the others have already pulled the Piranha Plant out by his roots. They carefully placed the plant in the pot, to which he instantly adjusted to having the freedom to move around.

As the days had passed, the survivors slowly start to learn that the threat who destroyed their worlds was Galeem from the Supporters they had attacked. They allied with a few Spirits and became the Forgotten Resistance, by which they took shelter in a small ship.


One night, Byleth looked out into the sky, watching the thunderclouds roar in the air. It had been five years, and he was trapped on an island with strangers from another world. Sure, he's heard the legends of King Marth and his ancestors, as well as heroes from lands around his continent. But where can he find his students? The Seraph of Order was going to notice them at any moment, and they'll be stuck on this planet forever.

I wish there was a sign, Byleth hoped. If something, anything, can show a shred of wonderful things to come, then please give it to us so we can finally be free from this planet. In a twinkle on his eye, the professor looked up into the thundering sky to see a shooting star in the distance. His eyes widened with surprise as he leaned over the edge of the ship to get a better look. There, clinging onto the star for dear life, was the answer they were looking for.

The last of the trophies to run away.


Byleth was distracted by his train of thought the second he saw a large rock flying past his face. The professor looked to his right to see Sonic in the training room again, still trying to hit the sandbag with as much power as he could put his energy into. Vines and air gusts blasted out from his fingertips, and he was more accurate in his hits. However, his breathing had gotten more louder, and his messy quills and baggy eyes were more noticeable. The professor, relieved that he didn't get hit, looked at Fox McCloud, who was waiting at the door.

"I still don't understand why Sonic's acting like this," Fox sighed. "Sure, he may have sacrificed his life to make Kirby escape, and sure the two dragons have tortured him in some way, mainly Dharkon. But that doesn't give Sonic an excuse to become cruel and unforgiving to the Seraph of Chaos. Sonic doesn't deserve this. None of us do. He REALLY is determined to stick it up to the monsters that double-crossed us."

"Why doesn't he just relax?" Byleth asked. "Most of the other fighters seem to be doing it before the Dharkon Void opens up." The Star Fox mercenary took a quick glance at the professor, shaking his head.

"It's not as simple as you would think," Fox sighed. "He's traveled to literally every universe in existence, afraid of losing us. However, it looks like that hedgehog might not be so lucky after all. The scars in his eyes give off the sense that he's not telling us something. Remember when the Mii Fighters attacked us ten years ago? Well, I know you don't remember because you arrived after Galeem came here… the point I'm trying to make is: he's saying the Mii Fighters no longer remembered him. Everyone had their secrets exposed except for him. He seems so angry now… almost like he's no longer the hedgehog we knew and loved. Before we experienced the memories for ourselves, he was always the adorable little piglet that backed up our backstories. I just wish those days returned. Something happened to his planet. I know it. He doesn't remember it and doesn't want anyone to remember it. It seems as though when we return home, we'll forget all the stories of the other universes. He can hardly stay awake, and he wants to unleash his anger on our enemies. But it looks like he doesn't know how." Byleth watched as the blue hedgehog growled in anger as he began to generate a powerful barrier around him, with the seven Rainbolements targeting the sandbag.

Fox and Byleth watched with fear in their trembling eyes as they saw the floating hedgehog drain his powers to become at his most vulnerable. The blue hedgehog landed on the ground, panting heavily. He then felt something drip from his nose, and he wiped it off with his fingers. He suddenly noticed he had a nosebleed. The few blue quills on his spines were beginning to fall off, and they were a healthy color too. Sonic slowly began to realize that these powers were doing something to his body the more he began to exhaust them, and not in a good way. It was as if the out-of-control powers were slowly taking over his mind.

"I'm running out of time," he whispered, holding onto a small number of quills he molted. Byleth looked at Fox McCloud in grief. He wasn't even in this Super Smash Brothers team for a while, and he already began to feel sorry for the blue rodent. The professor placed the device in his pouch, knowing that little thing wasn't important right now. Just then, an alarm rang throughout the futuristic ship, alerting every fighter on board. Sonic instantly heard it blare out from the walls, and he quickly dashed out the entrance to the main deck. Byleth and Fox followed after him, running as fast as they could.


As the alarm continued blaring around the Legacy, Sonic made it over to the main deck to see a giant hole rip below the ship. It had a violet, flaming outline, opening up with veins of blue and white spiraling into the center. It expanded as wide as it could go, destroying any floating islands in its way. Sonic gazed into the giant hole as a smirk stretched across his face.

It was the Dharkon Void.

The three ex-Ultimates Reborn saw Sonic standing on the edge of the deck, his back facing against the Draxian Void.

"Sonic! Wait!" the Mii Gunner called out. However, it was too late. Sonic fell behind himself, falling deep into the void. The other fighters made their way to the deck, with Byleth and Fox arriving first.

"He just fell in there!" Gilbert pointed out, instantly climbing over the edge. "We have to go after him!" The Mii Swordfighter jumped off the ship, surprising the other fighters.

"Let's go people!" Fox spoke, pushing Sieg and Sherry off the deck as he jumped with them. Every single one of the fighters fell off the ship into the Dharkon Void, with all the Mii Fighters and Spirits they rescued watching as the Shadow Bugs swirled around the abyss. Wherever that hole would take them, they have to win against the Lord of Darkness.
