---

Zeydaan would be relaxing at home. They had a pretty uneventful weekend all things considered. After their last adventure in a dimension of witches and titans, they figured they could use some time to relax. However, this would change the moment they went to open their mailbox for anything sent to them that day. And to their surprise there was one single letter. It was about the average size of an envelope, although the color of the paper was a bit more orange than it usually was. But what got their attention most of all was the big wax red seal in the middle of it. They would close the mailbox and take it inside, turning it over. No written address or stamp. The only significance to state where it was from was the design of the seal. On closer examination they recognized just what it meant; it was the spherical design with a set of cross-like lines through it. Or otherwise known as the Smash Brothers symbol.

Now Zey was aware of this crossover world of different dimensions, given they’ve met several of the characters in the past and even become a few of them. However, they had never been given an invite directly this way. They figured, bottoms up, and broke the seal, opening the envelope. There was a bright flash of light, squinting their eyes as they felt their body grow light as air. Falling through what felt like a column of light, until they would feel their paws reach solid ground. As the light cleared from their vision, they would be met with something truly magnificent. They were standing on an upper viewing platform for a massive, rounded arena. It was packed to the brim with cheering crowd members, many of which were minor characters. The middle of the arena was a large green field, with two individuals duking it out with all their might. That of which being the easily recognizable Mario and Kirby.

But before they could do or say anything, they felt a tap on their shoulder from behind. They would end up turning around, and a grin spread across their muzzle as they instantly recognized the familiar face. The woman standing in front of the fae-wolf was none other than the Welsh cat-blade from the dimension of Alrest, Nia. The sassy silver-haired cat shortie would place her hands on her hips sassily with that usual smirk she had. “I see ye got my letter, wolfy~” Zey would rub the back of their head with a chuckle, happy to see an old friend like her. Not only a friend, but someone Zey had turned into often in the past in many situations.

She would gesture to follow, and Zey would oblige. As she was leading them in the back areas of the arena, where most of the worker characters would keep the whole show running. “So, I didn’t invite ye for no reason, I need yer help.” She would flick their tail a small tad as she would lead Zey to the main waiting room, close to the fighting arena entrances. “So Samus o’er on th’ other side needs a competitor due tuh’ Ridley takin’ a sick day.” Zey was aware of both, Ridley more specifically, but the thought of the big, enormous menacing bio-dinosaur having to call in sick was a funny one. Zey would listen to her continue to explain, the crowd was particularly excited for a rival fight. But even if Ridley couldn’t come out, an unheard-of combatant like them would make for good entertainment.

“Use some o’ yer powers! Lead the crowd on an’ give Samus a good ol’ run for er’ money~” Zey would nod, taking a bit of a deep breath in preparation. As Nia gave them another pat on the back, with them going to take a seat as they waited. Eventually, after almost 30 minutes, a Koopa Troopa would step out with a clipboard and ref’s outfit. “Ridley’s replacement! Yer up!” Zey would stand, nervous, but also a little excited they’d get to take part in one of the most fantastic competitions in the multiverse. Nia would snicker as they would walk towards the door, “Break a leg! Ye got this!” she’d say in jest. They would take steps out onto the large green arena as the crowd would erupt into cheering, a large screen above them showing a close-up camera shot of Zey. The fae-wolf would end up waving to the crowd, if not a little embarrassed. And on the opposite end, in all her shining orange suited glory would be Samus Aran … the Samus Aran Zey was so well familiar with, who the crowd would cheer louder unsurprisingly. Zey would have thought up a couple good forms for fighting while they had been waiting. The first one they felt would be a crowd pleaser, while also maybe catching Samus off guard as the announcer counted down. 3… two … one…Fight!

And instantly Samus began to charge up her beam attack, her metal boots thumping against the ground. It would be important to mention that ever since Zey got here, their powers felt more … flexible. Like they felt the expanse and interchanging abilities being more heightened than usual. Although Zey would run towards her, as they would focus on their abilities and swipe upwards, knocking the cannon upwards. Samus would kick them back, only to realize they were holding a tennis racquet in their paws. Paws however, that were now smoothing and swelling into thick white gloves with more manly and lanky fingers. Samus was a little jarred for a moment, as the thick and soft clothing material was rapidly converting up their arms. It was a deep purple, and as it replaced their fur and skin of their arms, they would get longer and lankier. Their elbows bent a little easier and they felt physically stronger, their chest flattening and stretching as they grew taller.

He had a bit of an odd figure so this was a bit difficult for them, but Zey could do it. Black overalls rapidly replacing their chest with round gold buttons on each side, with them slung over their longer, furless shoulders. They felt the black overalls stretch and thicken their legs as they got rapidly taller. That odd lankiness bent at the knees, with their feet paws curling and fusing into sleazy orange shoes. The backs of their gloves would have backwards Ls, ones a lot of people in the crowd would be familiar with as they gasped. And Zey felt the oddest parts of the changes eating up their face as they ran forward, feeling male as their fur was being swallowed by scratchy human skin. They felt their chin jut and swell out, cracking their jaw as it reshaped to be more defined and a brutish sort of look. The skin stretches their jaw, and particularly their mouth out over their face. Teeth gnashing and flattening together to form more human shapes. As their black, messy hair would slick back into a light brown pompadour of sorts. Their furless ears would stretch out the sides of their head.

The end of their flat nose would feel nasally as it swelled out like a balloon, curling out and turning pink as their eyes flattened and grew out across their now furless, itchy skin covered face. Thick, gaudy eyebrows curled over their eyes as they keeled in to look skeevier. And with a plop of a purple hat bearing the same logo as their gloves, or rather his gloves, Zey had turned into a perfect copy of Waluigi. He was surprised to find had way more physical strength than he expected as he shot at Samus. Never had the crowd seen someone capable of transforming in such a way other than Kirby, but even his changes were minor. Samus would dodge and knock the kicks and tennis racquet-based attacks, on the defensive. This was until she would charge forward and slam into his chest, knocking him backwards.

She was adapting to his moves, surprisingly. As he chucked the racquet at her to bonk off the visor of her mask, he would quickly focus on another character. And two words came into the big lanky man’s mind as he would hold out his glove, a green crystal forming in it. “Chaos…Control!” And for a few moments, time slowed down. But it was enough time for him to quickly reshape his body, his lanky arms and legs were rapidly shrinking as his gloved hands grew even larger. Golden rings forming as bracelets around his wrists with his clothing material melting away to reveal perfectly smooth black fur taking over his arms and legs. His orange shoes would swell and grow more complex, curving up into Air shoe designs. A mix of black, white, with red edges and golden rings around his ankles. His rear would have a small spiked black tail prodding out, with his shortening chest fluffing out into a small tuft of white fur amongst the black.

He felt the abilities of time and space filling his being as he clenched his fists. Especially as he felt his odd, shaped head start to take an even odder metamorphosis. His mouth and jaw pulled forward and thickened with new sensations. His lower jaw and cheeks had taken an orangish cream color, and his once long pink nose would compress into a small and round black one. His short brown hair would explode out in luxurious and glossy thickness as it would clump together and solidify. It would rapidly darken and thicken, flaring out like a starfish, as red streaks formed in the black as the fur had compiled into perfectly styled quills. Their eyes would also grow and stretch, becoming more cartoonish with deep red eyes. They looked far more serious and less goofy than Waluigi did, or once again he did. As his new ears formed, time would return to normal, and Shadow the Hedgehog had been the next form Zey took.

He would charge forward, knowledge of martial arts and speed filling his veins. He would warp around the bounty hunter as she kicked and fired in his direction, clearly getting overwhelmed. He would knock a kick into her visor and smack her back, only for her to stop, waiting for him to make a move. And when he went in for a strike, she would grapple him with a beam and fling him up, slamming him against the ground with a pained crack. He would grunt and leap back. He would hold out the chaos emerald he had used temporarily … and crushed it. He figured he might as well fall back on what he was good at. As his form was encased in light, the crystal would go to attach to his chest as his fur was shed like water or a coat.

His outline got slimmer, with soft womanly skin and a nice figure. As his large hairdo would shorten into a smaller do, the shed fur would compress over his body into a tight and cozy outfit. It was a yellow jumpsuit of sorts, or a sweater, with large armor-like boots covering his legs. His smaller hands now enveloped in gloves still as tassels flared out his neck as a scarf. He felt his muzzle shrink into a human face, with small fangs and a cute, yet feisty demeanor. Although he wasn’t the best explanation, more she, as the light dismissed, it was revealed Zey was now Nia. Or rather her original design as she would form the rounded blades in her gloved hands. Samus would lay fire to her, only for her to dodge and swipe them around, much more agile.

The audience was at the edge of their seats, silent and completely invested in this intense match as if she would clash with Samus. They both would hold their ground, trying to push each other back to gain ground. Zey knew this body and wasn’t letting up. Before going to duck down and kick Samus’ legs out from under her, only for the Bounty hunter to spin and do a backwards kick upwards to strike Zey in the chin. It felt like with every hit Zey was more in danger of being knocked back off the arena. It was like their own personal gravity was getting weaker with every hit, but so was Samus. Zey figured now it was best to fight fire with fire, or rather fire with space dinosaur.

In an ironic fashion, Zey would smirk, her sharp teeth showing before they would rapidly begin to sharpen and stretch out. Across their body, their limbs would crack, snap, and extend. Their fingers would tear through their gloves, revealing sharp purple claws. Ones that would dig into her cute face as she tore it off like paper. And bursting out would be an enormous purple scaly muzzle, filled with sharp fangs as they tugged and gripped the Nia shell and tore it in half to be free of it rather quickly. This would catch Samus the most off guard as an enormous sharp tail shot out jammed into her chest. Zey felt this primal, familiar feeling in their chest. Their bony and enormous torso would grow out larger, with big flared out wings shaking off any remaining bits of the Nia body. And staring through bright yellow eyes would be Zey in the form of the space pirate Ridley, the one who couldn’t make it today.

This got the crowd very excited as he would flap his wings and slam his feet down at Samus. This was the first character who was on the main Smash roster, so it was exciting, letting loose bursts of flame from his maw and followed up with further tail stabs and slashes and swipes from his wicked claws. Samus was getting hard to keep up, taking hit after hit until she found herself knocked to the edge, charging up one large final blue beam attack. But just before any of them could attack, a flash would appear in the air, and the rainbow Smash Ball would float around. This was it, the game ending opportunity. Both fighters leapt up towards it, Samus firing off her charged blast, but Zey would manage to fly up quickly and slam the tops of their wings into the ball of energy. And all at once they felt the rainbow strength fill them, landing in front of Samus. And before she could have any chance to retaliate, he would grab her, flinging her up into the sky as he shot up after her.

She would be knocked into space, slamming into the side of her ship as it flew past. This was well recognized as Ridley’s Final Smash, and Zey felt fantastic pulling it off as he charged his breath attack. And with one powerful screech, he would let it rip, blasting through Samus and erupting the ship into a fiery blaze. Both would end up falling back into the Arena, with Zey landing … and the defeated Samus landing near. And just like that the crowd would erupt into roaring cheers. Chanting Zey’s name over and over in the process. As the dinosaur would look around, they would compress and shrink back into their cute and furry self. They would wave to the crowd, the largest grin on their face. It wouldn’t take long for Samus to be lifted up by a mechanical platform, one that would glow and heal her injuries as she stood up, soon letting her down.

Zey would hold out their hand to her, and she would look up and gently take it, standing up and shaking back. “You did well, I look forward to seeing what you can do in the future.” She would remark, which made Zey feel a sense of pride fill their chest. And as the bounty hunter strutted off, Zey would take one more look at the crowd, and they felt fantastic.
