As Cloud Strife and Link began falling through the floor that Dark Samus was launched downwards, the two warriors were pretty amazed by how deep it was. Was the knockback so powerful it sent an Assist Trophy tumbling several floors down? Eventually, Cloud managed to see the floor as he held on tighter to Link.

"Hold on, elf," Cloud said, hugging Link closer. Spreading apart his legs, the 1st-class SOLDIER managed to land perfectly on the floor, causing a booming noise. Link then slowly let go of Cloud when he felt that they were on solid ground.

"Whew… Thanks," Link sighed, adjusting his blue tunic. "Say, do you know where the light switch is?" From what the two warriors could gather, they were somewhere in a really dark room, with only a few glowing objects they can't even make out. Link then pulled out his Sheikah slate, pressing a button that triggered the device to switch to flashlight mode. The light emitted was dim, but it was bright enough for the two swordfighters to find a switch. Then, Cloud pointed at a rusted switch board, where only one button was visible.

"…Is this it?" Cloud asked Link, forgetting that he accidently flicked the switch. Just as the lights buzzed on, both Link and Cloud Strife looked around, seeing all sorts of wacky items in treasure chests, shelves, boxes, and too many storage devices to count. Shelf after shelf, the two warriors could figure out that on one side, there were lots of spherical orbs, some red, others violet-and-magenta with a large "M" on the front, and there was a button in the center. On the other side of the room were the rainbow-glowing capsules from before. Cloud was amazed by how many there were, as well as Link.

"What are these things?" Cloud asked, turning his attention towards the Hero of Hyrule.

"Back at the Midair Stadium, we called them Assist Trophies, Pokéballs, and Master Balls," Link answered. "The Assist Trophies, as you saw before, are capable of summoning other warriors that can only help the user. The Pokéballs and Master Balls, well, summon Pokémon, though the Master Ball calls forth the pseudo-legendries and the legendries, both of which are extremely hard to find. I'm actually pretty surprised by how many there were back at the vault. Be careful, Cloud. If you touch one of these items, the summoned warrior will be bound to the world forever thanks to the alternated rules…" As Cloud walked near the Assist Trophy capsules, he saw figures dancing around, but not in grace and moreover the pain they're going through as becoming mere prisoners of their bound fate. Suddenly, they've heard some demonic laughing from the other side of the room.

Cloud Strife and Link pulled out their weapons, finding out the laughter is coming from not a Primid but Dark Samus herself. The blue Phazon pulsed through her body as she banged on an old computer box next to her. The black-and-blue creature started screeching unholy cries, and the computer box automatically picked up the screams and translated them.

"Are you listening to the cries of the Phazon warrior, Dark Samus?" the Subspace computer spoke as it translated Dark Samus' cries. "If you are, then try to catch me if you can."

"What is this place?" Cloud asked, his glowing cyan eyes brighter than before.

"Here, you are seeing the birth of a new nation," the Subspace computer continued as Dark Samus kept growling. "Everyone knows fighters alone can summon assistants and Pokémon into this world, whether intended for good or evil. Once our professional warriors call them forth, the Subspace Army will become unstoppable. Hopefully you wouldn't be around to experience the glorious rebirth because you'll be dead by then." Dark Samus then fired an alien web-coated missile at the computer box next to her, destroying the device. The lights flickered for a moment, and once they were fully on again, Cloud and Link gasped in awe when they saw Dark Samus on top of a yellow-bodied warrior with a single red eye in the center of its body – the Yellow Devil.

Cloud couldn't handle it anymore. He ran to the Assist Trophies, leaving Link behind in front of Dark Samus and that monstrous thing. The 1st-class SOLDIER then grabbed ahold of a random Assist Trophy, touching the bottom of its base. As the rainbow lights flickered into confetti specks, everyone saw what appeared to be a blond-colored poodle with her hair tied in a bun, and she was wearing office clothing similar to a mayor's assistant. The anamorphic dog being looked around, finding herself in a scary place at a bad time.

Dark Samus suddenly started screeching, commanding in her own language the Yellow Devil to attack. The Phazon warrior jumped from the robot's back onto the floor, where she levitated, and the Yellow Devil broke itself into multiple parts that flew at the three warriors. The Yellow Devil then reassembled back together, its red eye gleaming at Cloud Strife and Link. Meanwhile, the anamorphic dog didn't know what to do the moment she was immediately summoned as Dark Samus charged right towards her with a static arm cannon.

The anamorphic fighter dodged the volts, swinging out her fishing rod. The hook latched onto Dark Samus' neck, with the line wrapping around her. The dog-like mayor's assistant, with a confused and terrified face, reeled in Dark Samus as she was struggling, but the Phazon warrior burned off the line quickly and used a plasma tether to draw the Assist Trophy in.

Meanwhile, Cloud Strife jumped on top of the Yellow Devil, slashing at the robot's single eye while Link ran in from behind to attack as well. The Yellow Devil then started shooting small but powerful lasers as Link blocked them with his Hylian Shield. The blue-clad warrior then jumped up and threw a blue-glowing bomb at the Yellow Devil, detonating it in a powerful explosion with his Sheikah Slate. However, Cloud was hurt by the explosion too, and he flew right into Link as the Yellow Devil was badly damaged. As Cloud Strife quickly recovered, he saw that he was on top of Link's body after the collision, the two of them facing each other.

"Careful next time!" Cloud yelled.

"Sorry, sorry," Link stammered. When the two warriors looked behind themselves, they saw the Yellow Devil was creating a big explosion, a growing fireball suddenly disappearing out of existence as the Yellow Devil was gone. Once Link and Cloud got up, Dark Samus immediately roared at them as she threw the summoned anamorphic stranger onto the floor with her Phazon tether. The Assist Trophy was badly wounded and was trying to unleash a confetti popper, but Dark Samus was glowing blue with wrath as she charged a powerful plasma orb to fire and finish the summoned fighter for good. Just then, Link threw his boomerang, ricocheting off Dark Samus' black exoskeleton. The Phazon warrior jerked her neck to see Link charge up his Master Sword's power and Cloud Strife jumping on top of her. The 1st-class SOLDIER thrusted his Buster Sword onto Dark Samus' head, pinning her down in place as the blade cut deep into her tough skin. Link instantly launched his sword's power, unleashing a wave of light, and knocked Dark Samus out.

Once the Phazon warrior was lying down unconscious, Link and Cloud Strife looked at the trembling Assist Trophy that they summoned, who was wounded at that time. The anamorphic dog then got up quickly, brushing off her scratches. With a cute voice, the summoned fighter began to speak.

"Thanks for saving me," she barked. "I was beginning to become cramped in there…" Link rubbed his head as Cloud stared at her.

"Oh, I just forgot," the Assist Trophy continued. "I haven't introduced myself. My name is Isabelle, assistant of the mayor of Smashville."

"Isabelle?" Cloud Strife asked. "Last time we were at Smashville, the whole place was deserted, and we were told by Sephiroth that he killed everyone off for food except Villager. Didn't think he would mention you."

"I think there were a few survivors," Link butted in.

"Geez, that's terrible," Isabelle chirped. "I'm just at least glad Mayor Villager is okay."

"Villager was mayor of this town?" Link added in question. "He looked like just a kid, let alone younger than Toon Link or Young Link…"

"Well, best not to underestimate the little guy…" Cloud answered. Just then, the three warriors looked at Dark Samus slowly crawling up. The Phazon warrior was wobbling, trying to charge up a plasma ball but failing.

"Hey, Isabelle," Cloud asked. "Can I borrow your fishing rod?" Isabelle, without question, gave the 1st-class SOLDIER her fishing rod, and Cloud suddenly cut off a long piece of the line. He glided to Dark Samus before she could even react, binding the Phazon warrior's arms behind her back and ending by creating a leash from no more than tying the leftover line around her neck. As Dark Samus was struggling with the bondage and screeching, Cloud Strife gave the Phazon alien's leash line to Link.

"We gonna get out of this place," Cloud said. "Until we reunite with the rest of our companions and burn the Yggdrasil to the ground, Dark Samus is coming with us as prisoner." While Dark Samus continued howling unholy cries as she tried to untie her arms behind her back with her arm cannon, Link took ahold of her leash as he pulled her towards her.

"There's a way that leads us out of this room," Cloud then said, pointing to a doorway. "If we go through there, we might find someone to help us. Isabelle, you're gonna be on our team from now on."

"What?" Isabelle exclaimed. "Me? I barely even know how to fight! You saw how I dealt with Dark Samus. I hardly have any experience from throwing all that fruit…"

"Understandable," Cloud replied. "However, the least you could do is remind us when Dark Samus is attempting to get away…" Cloud Strife and Link then walked off to the door, dragging Dark Samus along with them as hostage. Isabelle then shook her head, running towards the two warriors to join with them.

"Hopefully we don't run into powerful enemies, don't we?" Isabelle chirped.

"We hopefully won't," Link answered as the four warriors went through the door, leaving an empty room filled with thousands of wacky items, Assist Trophy capsules, Pokéballs, and Master Balls…
