Across The Multiverse
16. Here Comes the Boom (Part 3)
Previous ChapterNext ChapterEarth 597
Bygone Island
Team Sonic stood still, they couldn't move due to the sheer terror they felt upon seeing the metallic menace with their leader's visage slowly approach them. The dust from the crater still rose as Metal marched forth, having just demolished Boom Sonic with pure ease. And now he was coming right towards them, pure murder in his optics.
Meanwhile the Flybot continued to observe, zooming in so his creator could see what was happening. Orbot and Cubot were shaking, their optics wide in fear. Boom Eggman leaned forward with his mouth agape, his eyes wide, his coffee spilled on the console. As if he didn't have a lot to deal with already, now there was an imposter out there who not only copied his design, but also had the gall to make it better than his?
He would never admit that openly, of course, he has a reputation to uphold!
But the point stands. Whoever this imposter was, he was good. Too good.
Further investigation would be needed.
But back to the matter at hand, Metal stomped forward, his claws ready to tear flesh, as he heard his master's voice in his ear. "Well done, my boy! Now that the blue imposter is out of the way, deal with the other rabble and move to the next dig site. We have a Spear of Destiny to collect!"
Metal Sonic nodded and continued forward, but stopped when his hearing processors picked up something shifting from behind him.
"H-Hey, Tin Can!" A weak and cocky voice called out, causing Metal to turn around sharply and glare at the shaking hedgehog limping his way out of the crater. Holding his arm, Boom Sonic smirked and said, "We're not done here yet."
Team Sonic practically begged for their leader to stay down, but he simply smiled as Metal turned to face him.
"He really is a resilient little maggot in any reality." Eggman hummed. "No matter, despite not being the real Sonic, the sight of a dead Sonic is enough to make my day. Normally, I'd tell you to make it quick." Eggman then grinned. "However, because of this idiot's decision to defy me, I want you to make it nice and slow."
Metal nodded before shooting forward and seizing Boom Sonic by the throat and hoisting him into the air, tightening his grip around his windpipe. Team Sonic cried out and tried to rush over, but they could barely move due to their injuries. Metal Sonic began chocking the life out of him, the blue hero gasping desperately for air.
"I'm going to relish watching the life fade from his eyes." Eggman laughed.
Metal couldn't agree more.
But before he could, something pinged on his HUD, causing him to loosen his grip on Boom Sonic and turn around. He zoomed in and saw...
Him.
He dropped the fake and gave the incoming force his full attention. The dust cloud behind the incoming foe was massive, and became even bigger when a sonic boom sounded off and he shot forward at unparalleled speeds. Everyone turned around as saw a blue blur zip right past them.
And collide right into Metal Sonic, sending the robot flying back.
Team Sonic gasped loudly as they saw who it was that saved them.
And Boom Sonic was beyond shocked as he stared at... Himself. "Y-You... You are..."
"SONIC?!" Team Sonic shouted.
"SONIC?!" Eggman and The Vees exclaimed right into Metal's ear.
"ANOTHER ONE!!!" Boom Eggman shouted from inside his lair.
Sonic smirked and folded his arms, pointing his index finger on his right hand upward. "The one and only." He boasted before zooming forward at speeds that even Boom Sonic hadn't been able to achieve. He saw that Metal had gotten back up and decided to end this quick.
The two rivals broke the sound barrier to reach one another before colliding in the middle of the canyon, interlocking hands as they fought to overcome the other. "You might know everything I'm going to do, but that's not gonna help you, as I know everything you're going to do! Strange, isn't it?" The Blue Blur grit his teeth as he pushed forward against Metal Sonic.
The two eventually broke apart, the both of them sliding away from the other. Metal would've continued the fight, had it not been for a shadow tentacle to sprout from the ground and wrap itself around his middle. He looked up comically before being flung into the side of the canyon.
Smirking knowingly, Sonic peered to the left to see Alastor swirl from his shadows, his everlasting smile not leaving his face. "What an odd contraption." He commented before stamping his staff on the ground, summoning more shadow tentacles and shooting most of them forward while using another to grab a nearby VoxTech Drone and crushing it.
"WHY THE FUCK IS ALASTOR HERE?!!!" Vox swore loudly.
Back to the conflict, Metal boosted forward, dodging left and right to avoid the tentacles and make his way to the waiting Radio Demon. Al's smile widened as he disappeared into shadows as a silver spear soared right into Metal's face, sending him crashing down.
He looked down at the spear and picked it up, looking up to a scowling Vaggie, who flapped her angelic wings to keep herself in the air. Metal's eyes glowed furiously as he threw the spear right back at her, intending on impaling her. But it was stopped by a trident, the spear falling into Vaggie's waiting hands.
She looked over to Charlie, who looked sheepish while struggling to fly with her new wings. She was new to this, okay! She scowled down at Metal as he clenched his fists in seething anger. Sonic tutted in disappointment as Metal readied himself for another fight, but stopped when Boom Sonic walked up and stood next to his counterpart. "Not sure what's happening here, but I wanna see how this guy can handle all of us together." He glanced behind him to see Team Sonic standing behind him.
Metal hated to admit it, but he was beat here.
And the Legion knew it too. "Metal, g-get the he-e-ell out of th-ere!" Vox ordered, his voice glitching from anger at seeing Alastor. "We have shit-shit-shit to do."
Shaking in rage, the robot had no choice but to comply. So, giving one final glare to his loathsome copy, Metal shot up into the sky and flew off. The Spear Fragment obviously wasn't here, so he needed to search elsewhere.
"Well, that's disappointing." Alastor sighed. "And here I was hoping for a little more mayhem."
"You're sick, you know that?" Vaggie grumbled as she furled her wings.
"And I could give a damn what you think."
Sonic sighed and smiled, before opening his eyes to see Sticks right in his face, examining his arms, shoes, quills, basically everything about his appearance. Sonic scratched the back of his head in confusion, a little weirded out by Sticks' observations. "Um... What are you doing?"
At that query, the badger got right in the hedgehog's face, causing him to lean back as she rambled, "You're Sonic's evil clone from another universe here to replace him! Admit it! Who do you work for?! The Government?! I bet it's the Government! You're shadow Government is here to replace us and make us our slaves!!!"
Sonic simply looked to the Hazbins, who shrugged at the hedgehog in either sympathy for his current predicament, or amusement in Alastor's case, before slowly glancing back at the paranoid badger before clearing his throat and leaning forward with a knowing and cocky grin. "If that's the case, then why did I just help save you from ole' tin can earlier? Hmmm?"
"To lower our guard to get us to trust you." Sticks huffed. "I know how you shadowy suit types work."
It was then that the rest of Team Sonic slowly approached with either astonished or bewildered eyes. "So you are Sonic from another dimension!" Boom Tails proclaimed excitedly.
Sonic looked down to his younger brother's counterpart and ruffled the top of his head with his hand. "Got it in one, bud!"
"But if that's the case, then how are we all not destroyed right now?" Boom Amy couldn't help but point out. It was a good point, the anomaly should've begun and threatened their entire universe. "If there are two of the same person coexisting in the same dimension for too long, it could cause a catastrophic anomaly that will destroy our entire universe!"
Sonic and the Hazbins looked at each other knowingly while Alastor licked his lips to spook out the badger slowly leaning towards him. "Yeah, uh, we may have an explanation for that." Vaggie laughed as she rubbed the back of her head awkwardly.
"Although it's a bit of a loooong story." Charlie walked over to the group, hiding her demonic wings before holding out her hand. "But first, hi! My name is Charlie!" She introduced herself to Boom Sonic, who slowly took her hand and shook it. "And these are Vaggie and Alastor!"
"Pleasure to be meeting you, quite a pleasure!"
"Hey."
Boom Knuckled unsubtly leaned down to Boom Tails and loudly whispered, "He doesn't look very friendly." He gestured to Alastor with his thumb.
"Oh, trust me, I'm not." His eyes turned to radio dials and the air around him began to shift before turning away and humming a merry little tune.
"Yeah, he's only here to settle a score with his boyfriend." Vaggie pointed to the retreating Radio Demon with her thumb, not noticing or caring as he stopped suddenly, his antlers slowly growing and a static screech sounding off from him.
"The very notion that I would be attracted to him of all people makes me violently ill." Alastor grumbled, hating the fact that he was under contract not to hurt or kill anyone. "You would be wise to remember to whom you are speaking to."
"Bite me."
"Okay!" Charlie shouted out, stopping the two from getting into another argument. "I think we have bigger things to worry about?"
Boom Sonic looked to his counterpart and smirked, "Gonna be honest, a liiittle jealous of you." He laughed as his counterpart smirked back at him. "I mean, I've only been to another dimension once! Man, wish I could have adventures like you."
"Never a dull moment, me."
"Apparently not, me."
Boom Tails looked up at Sonic, "So, why is it that we're all not dead right now?"
Sonic chuckled and folded his arms, a knowing smile on his face. "Well, it started with me ending up on a Yellow Brick Road..."
Meanwhile
"I CAN'T BELIEVE THIS!!!" Came the angry shouts from not only the livid Ivo Robotnik, but from the furious Vox too.
"WHY IS HE HERE?!"
"WE'VE LOST THE ELEMENT OF SURPRISE!"
"OF COURSE THAT OLD TIMEY FUCKER FOLLOWED ME!!! OH, AND OF COURSE HE BROUGHT THE TWO LOVEBIRDS TOO!"
"NOW IT ACTUALLY IS A RACE TO FIND THE SPEAR FRAGMENT!!!"
"THIS IS UNNACCEPTABLE!!!"
Meanwhile Valentino and Velvette simply watched with unamused expression at the two crashing out over their plans unfurling before their eyes. They were admittedly used to Vox's temper tantrums, but having two crybabies was too much salt for them to handle.
"Hey, dumbarses!!!" Vel shouted, causing their combined temper tantrums to cease and for them to turn to the doll. "Instead of whinging and whining, how about we figure out what we do next?"
The two villains stopped to ponder before something clicked in Vox's head. Something he noticed during the fight. An orb, insect-like robot was watching the fight. He looked to Eggman, and the evil genius came to the same conclusion. Someone was watching that fight.
And there was the high possibility that certain someone was a certain nemesis to a certain hedgehog.
After all, if another Sonic can exist here, then why not another Eggman?
Dr. Eggman's Base
The sound of the doorbell ringing caught Boom Eggman's attention, dispelling his theories as to who could've copied his Metal Sonic designs and improved upon them. The goofy doctor turned away from his whiteboard, which had crude drawings of Metal pummeling Team Sonic, one with Boom Sonic having stink strings rising from him, and one of himself looking all buff and muscular standing atop a hill with the residents of Hedgehog Village praising and cheering for him. "Ooh! I bet that's the girl scouts!" Boom Eggman squeed before rushing to the door, with Orbot and Cubot trailing behind him. "Now last time I gave them a 2 dollar tip. Now, I'll give them only one dollar! Mwahahahaha!!!" He laughed evilly before opening the door and dropping his jaw to the floor at who was on the other side.
It was himself, with three odd looking fellows standing right behind him, the moth looking one blowing him a kiss.
"Well, hello there, handsome." Dr. Eggman greeted with an egotistical smile.
Orbot and Cubot blinked their optics multiple times at what they were seeing while Boom Eggman took a cautious step back. "Steve? That you?" He was sure that this wasn't his robotic, shapeshifting brother from another dimension, but he had to be sure. "You don't look like Lord Eggman, and if you were another me, then our entire dimension would be destroyed by now."
"Oh, but that's exactly what I am, Ivo." Boom Eggman cringed, he hadn't been called that in a very long time, and it was weird to hear that name again. "You see, I come from a universe parallel to your own. For, I too, am Doctor. Ivo Robotnik."
But that didn't make sense! How could another version of himself be here without collapsing the entire universe? This was highly improbable and illogical.
"It's impossible!"
"Is it?"
"It couldn't be!"
"Couldn't it?"
"I'm-"
"Are you?"
Boom Eggman blinked again, turning to look down at Orbot and Cubot, who looked just as lost as him. He cleared his throat and turned back to his counterpart, who had an evil smile on his face, as did the tv man behind him while the short girl was staring at her phone.
The moth gazed at his lamp, seemingly entranced by it before he was elbowed in the side by the tv, breaking him out of the trance.
The goofy doctor took a step closer to his counterpart and got in his face, eyeing him distrustfully. "You do look like me." He eyed him up and down before adding, "But fatter."
"Okay."
"And older."
"Unnecessary."
"And there's that eggy smell."
"It's an expensive cologne!"
Boom Eggman raised his right hand, his modern counterpart doing the same, miming his movements. They both raised their left hands and held them close together. "But the resemblance is uncanny." Boom Eggman commented. "It's as if!"
They both tilted their heads to the side. "We're two characters in a fanfiction being voiced by the same actor!" They said together as they slowly turned their heads to look at the reader. Vox couldn't help but let out small snicker at that little forth wall break.
Both Eggman took a step away from one another while the slimmer one stroked his moustache, "If it is true that you are me, then you need to leave! You being here could cause a catastrophic anomaly that will destroy the entire universe!"
But Modern Eggman wagged his finger with a chuckle, "Ah, but I've already taken care of that." He reached behind him, causing his counterpart to arch an eyebrow, before pulling out the fragment of the Spear of Destiny. "Thanks to this, your dimension has been stabilized."
"How's a twig supposed to do that?"
"Ah, but this isn't any twig, my good doctor!" Eggman corrected. "This is a fragment of the Spear of Destiny!"
"Ooh!"
"Precisely! It is a weapon capable of altering reality itself, and the next piece we need to complete it resides in your dimension! And now that two fragments occupy the same world, it's stabilizing the anomaly that would destroy your entire world!"
"Okay, but that doesn't explain why you're here."
"Oh, Ivo." He shook his head, tucking the fragment away behind him. "Have you ever wanted to win? And I mean truly win? Seal your victory so much that the blue rat couldn't possibly undo it all?"
"Of course!" Boom Eggman answered honestly.
"Then help us claim the fragment of the spear, and everything you've ever wanted could be yours!" Eggman baited, slowly reeling him in. "Together, with our combined genius, we could not only rule this world, but an entirely new one at that! And the blue rodent, neither one, could be able to stop us!
Boom Eggman looked down and stroked his chin in thought. His latest scheme to make a video game to gain popularity had been a bust thanks to Shadow trying to destroy the universe, and he hadn't really been active lately. Plus, if what this fatter version of him was saying was true, then this could be the chance to finally defeat Sonic once and for all. He would be humbled, humiliated, and he would finally be the cool one while Sonic would be nothing more than a loser.
He couldn't help but grin at the thought.
He was brought back to reality when Modern Eggman spoke again, continuing his pitch. "Just think of what we could do together! You and me, finally claiming our rightful places, together!"
"Together?" He thought to himself. Yes. Yes, he could see it. They could not only destroy Sonic and his annoying friends, but they could do whatever they wanted without restraint, without any rules holding them back. Boom Eggman turned his head to the left and looked into the distance with a smile on his face.

Modern Eggman slowly leaned over, placing his head next to Boom's as he gazed on in confusion as to what he was looking at. Soon they were joined by Vox, Val, and Velvette, who were also wondering what it was that they were staring at.
Boom Eggman's "Perfect Day"
They started off at an amusement park, obviously called "Eggman Land" for obvious reasons, riding down a rollercoaster. As they plummeted down the slope, the two Eggmen raised their arms into the air and screamed to their hearts content while both Sonic's were being chased by Eggman fanatics with pitchforks.
The vision shifted to the two Eggmen ordering at the local "Meh Burger" and taking their lunches without paying, giggling like school girls while Team Sonic were taking residence in the trash, being pestered by nasty racoons.
It shifted again to Modern Eggman pushing him on a push bike that they had stolen from a little girl. His modern counterpart laughed joyously while he watched him peddle. Before falling off the bike painfully.
The vision shifted to the two Eggmen sitting on a park bench with Sonic strapped to a rocket. Boom Eggman pressed his communicator and sent the hedgehog blasting off into the sky, exploding into a firework while the two villains ate their fairy floss with smiles on their faces.
Back in reality
Boom Eggman sighed wistfully as he turned and shook his counterpart's hand enthusiastically. "I'm in."
But what Boom Eggman didn't know was that his more evil counterpart was sinisterly chuckling in his mind. "What an idiot. This was easier than I thought. To think that this buffoon is an alternate version of me. Bah! Ridiculous! Once we have that fragment I'll cut him loose, after all, what good are underlings if you can't use them?" He thought with a smile, secretly planning to use his counterpart to help secure the spear fragment for the Legion of Doom.
And the Vees were all on board with this plan.
It was time to get serious, no more games.
With Team Boom and the Guardians
"So, this "Spear of Destiny" can really house that much power?" Boom Tails as the group walked back to the beachside where Team Sonic had set up their respective huts. It wasn't much, but it was what they called home. After explaining the concept of the Multiverse, the Guardians, the Legion of Doom and the Spear of Destiny, safe to say that Team Sonic had quite a few questions.
"Basically." Sonic answered with a shrug. "That's why the Ancients split it apart in the first place. It was too powerful to be kept together, now Egghead and his new pals want to put it back together and we're here to stop them."
Boom Sonic shook his head with a smile, "Man, I'm jealous of myself. Never been on an adventure like that before."
"You know, I think we've been looking for the same thing." Boom Tails said, turning to the team he was walking with. "I've been picking up astronomical energy readings that shouldn't even be possible to pick up. They were even more erratic than the readings I picked up when our universe was nearly destroyed."
"That sounds like the spear!" Charlie exclaimed, happy that they have a solid lead in finding the spear fragment.
"Think you can get an exact location on the source of this energy reading, lil bud?" Sonic asked Boom Tails with a kind smile.
The young fox stroked his chin, stopping right outside his workshop. "Hmm, well the readings I'm getting are like ley lines, each connected from a different dig site Amy or some other archeologist discovered." His face suddenly brightened before he rushed into his workshop, making everyone look at each other with a shrug while Sonic chuckled while shaking his head, used to this sort of behavior from his own Tails. Boom Tails emerged from his workshop holding five miniature satellite looking devices in his arms. "Sonic." When both hedgehogs looked to him, he realized his mistake. "The alternate one." He clarified, his own Sonic nodding in understanding.
"Whatcha got there, Tails?" Sonic asked.
"These devices are energy readers!" He showcased the small devices before continuing, "I need you to place these at each dig site and activate them so we can triangulate the exact location of the origin of these readings." He passed the blue hedgehog the devices and nodded to him.
"Back in a flash" Was all he said before zooming off at speeds that caused his Boom counterpart to pout slightly, due to how much faster his counterpart was compared to him.
"So, this is your humble abode?" Alastor asked as he looked around at the multiple shacks that were built on the beach.
"Ooh!!!" Charlie's eyes sparkled as she pointed to Amy's shack. "That one looks fantastic!"
Amy looked up to the princess with wide and appreciative eyes, "Oh, you have to see the inside décor!" She grabbed Charlie's hand and dragged her into her hut, with a smiling Vaggie walking in behind them.
Alastor, meanwhile, rolled his eyes and descended into shadows. Might as well scare a few residents while he waits for some form of results to come about. Yes, he scared people randomly when he was bored.
Why?
Cause he's a dick.
Boom Sonic and the others decided to play some volleyball to pass the time. Not like anything big was happening right now, right?
Hedgehog Village
Another day, another Eggman attack.
The townspeople should really be used to this by now. Why were they even surprised anymore?
They were all currently being invaded by flying Bee Bots. Yes, that's what they were called. They were very similar to Buzz Bombers, but were more bee inspired in terms of design.
![]()
As they fired blasts at the stalls that made up the town square, multiple Crab Bots were snapping and tipping over trashcans, causing as much ruckus as they could. As per their template, the Crab Bots resembled typical crabs. They had a dome-shaped body that was covered by a red shell with stubby spikes on top, six knife-like red legs with silver edges, and a pair of red pinchers with yellow claws. Finally, they had a wide silver faceplate resembling a skull, with two mandibles and cyan eyes with slit-like pupils.

Now these robots everyone was used to, no, what threw them for a loop was the inclusion of these military-grade Egg Gunners that started destroying the town square, even firing upon innocent civilians, which was out of the norm since Eggman normally didn't target the civilians.
He mainly focused on Sonic and his friends.
The town's mayor walked down the steps with a concerned look on his face as Boom Eggman hovered down in his Egg Mobile. Mayor Fink was a relatively short anthropomorphic mouse with gray fur, pink skin and bright blue eyes. His head and torso came together in an almost egg-shaped figure. He also had round ears, a long naked tail, a bare belly, short legs, and a chubby bare muzzle with a medium-long black nose and a gray mustache. His attire consisted of an extremely narrow cream top hat with a green band, a cream jacket, an asparagus shirt with white collar and yellow rings, white gloves, a green-yellow neckerchief, and asparagus shoes with white gaiters around them.

"Ah, Mister Mayor!" Boom Eggman greeted with a smile, leaning forward in his vehicle. "Maybe you can help me? I seem to have misplaced a certain something and I'm having a bit of trouble finding it!"
"Whatever you're looking for, you won't get the chance to get it!" The Mayor said confidently, holding the lapels of his suit. "When Sonic gets here, he'll put a stop to this!"
"Did I forget to mention the "Eggman Twist"?" Boom Eggman retorted with a stroke of his glorious moustache.
It was then that a massive vehicle flew overhead, casting a shadow over the Mayor and the town. The vehicle was similar in appearance to that of a military jet. It had a central, egg-shaped cockpit with a glass cover and a seat for a single passenger. Instead of wings however, it had a hover ring on both sides. These rings were capable of folding up on the aircraft's sides. It also had a rocket engine on the rear for locomotion and thrust-based jet propulsion. Lastly, the vehicle had a black and white color scheme with red highlights, as well as black/yellow striped hazard strips on the sides.

The glass covering the cockpit of The Egg Pod slid open, revealing Modern Eggman in all his glory.
Mayor Fink let out a startled yelp, falling onto his rear and backing up in a hasty manner as he stuttered out, "T-Th-Th-There's two Eggmen now?!"
"Double your villains, double your fun." Boom Eggman said.
"Two Robotniks are deadlier than one!" Modern Eggman finished before pressing a button on his center console, activating the laser cannon that slowly emerged from the underbelly of the Egg Pod. Eggman aimed the weapon directly at the Mayor and chuckled, arming it as it crackled with red electricity.
As the Egg Gunners and Boom Eggman's Badniks continued to destroy the town, all the televisions in the town square suddenly turned to static before a massive, hypnotic red eye appeared on all of the screens. Vox took a step back from the screens, laughing as he managed to get everyone under his control. "Now that's good television!" He declared before teleporting out of the tv's and appearing in the middle of the town, adjusting his bowtie.
He looked to his left and saw a pink fog emerge from one of the alleyways in the square. There, from the smoke emerged Valentino and Velvette, with evil smiles on their faces. Vox chuckled as he snapped his fingers, activating the hidden VoxTech Drones that were placed all over the town square.
And finally, Metal Sonic descended from the sky and landed in a crouched position, his eyes glowing with hatred and rage.
Modern Eggman and his Boom counterpart cackled before the former leaned forward and asked, "Now, Mr. Mayor?" He stroked his moustache and asked the question burning in his mind. "Where's the fragment of the Spear of Destiny?"

Wow, Happy New Year, you lot!
Glad I got this out, cause things are getting dicey! As most of you have probably caught on, the relationship between both Boom and Modern Eggman is highly inspired by the dynamic between Gerald and Ivo Robotnik from Sonic Movie 3.
Which is peak btw, movie of the year!
Anyways, I just wanted to point out that since we're not gonna be getting a continuation of the Boom universe, I'm deciding to make this arc a sort of ending to the series, which means that not everyone is gonna make it out of this alive.
Yes, there will be some character deaths, as I said, this story is going to get dark, and the Legion of Doom isn't messing around.
So stay tuned for that.
Because I can almost guarantee that none of you know how this is all going to end.
Take care and be ready for what comes next!
