Battle in the Great Vault of Sulcus

**Battle in the Great Vault of Sulcus** is the fourth episode of Ben 10: Battle of the Omnitricies. This episode was written by Benzarro85 on January 12, 2022.

## Plot

The episode begins in outer space. A huge bank-like building was at the center, while all the stars, galaxies and planets were further away. Inside the building, Centur Squaar was busy giving the fellow aliens their withdrawal and deposits as requested. With the amount of hours he had been working, Squaar was extremely tired.

"Thank you for coming to the Great Vault of Sulcus." he spoke as the queue got smaller. "Next!"

The Vreedle Brothers were next. They walk over towards Squaar, which made him quite annoyed. They share an awkward silence for about a minute, while Centur Squaar clears his throat.

"Alright, gentlemen." he spoke. "I don't want any trouble, but I'd like to remind you that you're permanently banned from entering this bank."

"Aww, come on, Squaar." Rhomboid whined. "Please let us visit. We'd never rob this bank again. Right, Octagon?"

"Of course, we promise not to blow up and rob this bank." he responded.

Centur Squaar rests his head on his arm which was on the counter. "Yeah, I'm not buying it. You're lying. I can see right through you two. Always causing mischief when I'm working, it's not acceptable."

He points to the door. "I'd like you two to leave. I don't want any mischief happening at this place again. Do you understand?"

They understood as they depart from the bank, but what Squaar didn't know, was that they planted dynamite inside the vault anyways. As they entered their ship, Octagon detonates the dynamite as they explode, causing a ruckus. This startled Centur Squaar, before he got angry.

"Gosh darn. They've done it again."

With the Vreedle Brothers escaping with the Vault being partially blown up, the scene switches to a fight between Ben, Rook and Trumbipulor. Ben was in the form of Big Chill, dodging his heavy attacks whilst attacking back. Rook began firing at Trumbipulor who tries attacking back. Big Chill eventually swoops in and freezes his feet, causing him to fall over.

"Alright. I got him on the ground." Big Chill spoke. "You can take him back to the HQ prison."

"I'm not sure if he's working alone, Ben." Rook said. "What if he's working with some other fellow bad guys?"

Big Chill lands on the ground as he folds his wings into a hooded cloak. "I'll search for them, you keep him contained."

"Very well, Ben." Rook sighed, taking Trumbipulor into custody. Big Chill makes his departure as he flies across Bellwood in search for some more villains to fight against, until he finds a ship crashing down into the atmosphere. Confused, he flew down to investigate, until he witnesses the Vreedle Brothers exiting the ship.

"What the?" Big Chill spoke in a questioning tone. "What are you two doing here?!"

"We just blew up the Sulcus Vault." Rhomboid spoke. "It was very fun."

"About that. Me and Boid were supposed to get a deposit, but Squaar denied our visit. So we blew up the place."

The Necrofriggian sighed before he transformed back into Ben. "So let me get this straight. You blew up a bank all because Centur Squaar denied your deposit?"

They nod. "He should've let us deposit our Taydenite."

Ben calls Rook. "So, we've got company. It's only The Vreedle Brothers."

Octagon grabs out a blaster as he blasts Ben's phone out of his hand as it's screen shattered. With Ben looking at their direction, and Octagon ready to shoot again, Ben dials the Omnitrix and transforms into Spidermonkey, as he scurried over to them both, attacking them with his web, trapping them both.

They break free from his web trap as they both began firing at the Arachnichimp who dodges the attacks, before getting hit by the last blast, sending him flying onto the pavement. "Alright, maybe Spidermonkey wasn't such a good idea after all."

As soon as Octagon was about to fire again, Spidermonkey leaps at him and throws him onto the ground, as the blaster was knocked out of his hand. Spidermonkey attacks Rhomboid too, evading all his energy blasts from his blaster, as he was also knocked to the ground.

"Alright, maybe not. I guess Spidermonkey WAS a good alien for the job." he smirked, before transforming back, calling Rook. "I got them, they have been subdued. I'll bring them over."

A sudden smoke bomb is thrown in Ben's direction as the entire area was covered in smoke. As the smoke cleared, the Vreedle Brothers had vanished. Ben looked around, annoyed. "Aww man. I just let the bad guys get away."

Ben heads back to Rook who managed to successfully put Trumbipulor into the Proto-TRUK. With Ben getting in, Rook drives off to Plumber HQ. "They got away. Some smoke bomb came out of nowhere and led to their escape."

"We'll get to the bottom of this, Ben." Rook spoke. "We will find them with ease."

"I hope so." Ben spoke, feeling serious on their new mission.

The next scene opens to Ben hanging out with Gwen in her bedroom. Gwen was working on her assignment for college, while Ben was sat on the floor. Ben and Gwen never usually had the chance to hang out due to Gwen attending college, and Ben having to save the world, so Ben hanging out with Gwen was something a little out of the blue for him.

"I'm really glad we can spend more time with each other, Gwen." Ben spoke. "It's really nice."

"Of course. We don't get that time to chill out anymore since we're always busy." Gwen replied. "Especially when I have assignments to finish. They were always a pain in my butt."

"If there was one thing I'd like to happen right now, is for there to be a bad guy to take down. Just the two of us. Like the good old days."

"Giving us the sweet smell of nostalgia." Gwen chuckled. "I love it."

Gwen finishes studying as she closes her book. "I can track down some bad guys to fight, so it can cure our boredom." Gwen began to cast a spell to search for one particular villain to fight. She ends up finding the Vreedle Brothers once again. "The Vreedle Brothers? How does that sound?"

"Good enough, though I encountered them not long ago."

Gwen gets ready to go. "You coming?"

"Yeah, it may not look like they're doing anything, but they sure are a huge threat."

As soon as Ben and Gwen got ready to leave, the camera shifts to downtown Bellwood; Octagon and Rhomboid began to cause havoc by blowing up buildings and looting buildings. Ben and Gwen later arrive at witness the destruction that was going on as they attempt to keep a low profile. They were spotted seconds later.

"Great. Just when we thought we weren't supposed to be seen." Gwen scoffed.

"It's not like you don't stand out from the crowd, Gwen." Ben chuckled. "But we got what we came for. We got some action, and we're gonna kick some Vreedle butt."

Ben dials the Omnitrix as he skimmed through some selections until stopping at a various alien. He slams the core as he was engulfed in a green light. As the light disappeared, Ben had transformed into a new alien. He looked like a penguin, with blue-ish skin, and razor blades for arms. His name was Alien Z.

"Hey, Gwen. Check it out. I'm a new alien." Alien Z spoke, spinning around. "Isn't that awesome?"

"That makes me wonder how many aliens you have in that darn watch."

"Too many to count." Alien Z cackled. "I believe the Omnitrix said something about me having over one million aliens, but I think I might've gotten more since then."

"Doesn't surprise me." Gwen smirked, with her arms crossed. "What do you think he can do?"

"I'm not sure." Alien Z responded. "I've never used him before."

The Vreedle brothers began firing away, with Gwen protecting both her and Alien Z. Gwen began firing back at the Vreedle Brothers, while Alien Z was a little bit confused on his powers. He began to think, but since Gwen was ahead of the game, Alien Z leaps in and tries what ever he can to figure out his powers. After many failed attempts to figure out his powers, Alien Z slices the last blast from Rhomboid, which made Alien Z realise his abilities.

"Lazer fins?" Alien Z questioned. "Now that's pretty cool."

Alien Z leaped towards the villains as he sliced the blasters which exploded after they were cut. The impact sent them flying over the other side of the road. Later, Alien Z was about to attack them once again, before they got mysteriously teleported inside the vault. With Gwen, Alien Z and the Vreedle Brothers ending up getting confused, the Vreedle Brothers were confused at how the building was fixed.

"How did this place end up getting fixed?" Octagon asked Rhomboid. "We-"

"Blew up the place?" a random voice spoke. They exit the shadows, revealing themselves as Albedo. "I wouldn't have thanked you, personally. But, thank you for keeping Tennyson busy while I had the opportunity to rebuild this vault."

"Why would you rebuild this vault, Albedo?" Alien Z asked. "You're a villain. You're supposed to be wrecking things and causing havoc."

Albedo snickered. "Once again, you might have not listened to what I had said. You wreck things, and you have caused havoc before."

Alien Z transformed back into Ben. "Whatever you're planning to do is not gonna affect me or my cousin Gwen, right?"

"Why ask? The war is already having an effect. Me and Eon still have yet to gather the evil Bens, then our part is done."

Albedo takes his leave while Ben and Gwen try to catch him, but doing this meant the Vreedle Brothers would make their escape, so Ben had to stay behind and fight them. As the Vreedle Brothers grab out their blasters, Ben dials the Omnitrix for Shocksquatch but transforms into Decagon Vreedle unintentionally. Startled, Decagon looked at his hands, and examined himself.

"Oh no!" He panicked. "I'm a Vreedle!! AH!!!"

Decagon was startled as he began screaming and running before tripping up on his own two feet. With Octagon and Rhomboid managing to take their leave, Ben had to get used to this new alien as he got up and ran towards the two, leaping at them, causing the three to fall.

"You know us Vreedles aren't supposed to be... well... you know... smart." Octagon spoke. "It wouldn't make sense for you to immediately know how to use... uh... what do you call him?"

Decagon got up and dusts himself off, helping the two get up also. "I haven't thought this through. Maybe Decagon Vreedle? Since Decagon is the ten-sided shape."

"Ma isn't gonna like this, Octagon." Rhomboid spoke. "She never knew Ben had a Vreedle sample inside the Omni-watch-amahoozie."

Decagon sighed. "Omnitrix."

"Yeah, that. She'd kill us if we kept secrets from her."

"She won't, trust me." Decagon chuckled. "I'd be surprised if she knew I'm alive."

The camera switches to Gwen who was chasing after Albedo. Albedo continues making an escape. Gwen manages to cast a spell in which Albedo is blocked off by a magenta mana wall which made his stop running.

"You've got nowhere to run now, Albedo." Gwen spoke. "Let's just sort this out the easy way, alright?"

"You're making this too easy for me." Albedo snickered. "You maybe one of the most powerful beings in the universe, but you surely aren't the smartest."

Albedo activates the Ultimatrix as he transforms into Swampfire, as he throws a fireball at her direction. She swirls around as a tornado which reflects it back at his direction, in which he dodges. She grabs out her spellbook as she casts a spell in which Swampfire's pyrokinetic abilities get neutralised. Swampfire stopped as he started to chuckle.

"Silly Gwendolyn." Swampfire spoke, chuckling. "You're forgetting something. Remember the last time we fought solo? I used a sleeping spore on you. You passed out."

"Don't think I still haven't forgotten about that one, huh, Albedo?" Gwen smirked. "You may have forgotten, I'm still more powerful than you'll ever be."

"Oh yeah?" Swampfire spoke before quick changing into Chromastone. "I disagree."

Gwen throws a mana disk at his direction to which he absorbs it, exiling it back as ultraviolet beams of energy, in which Gwen manages to block the attack by shielding herself. She skims through her spellbook as she finds a rather familiar spell. She moves her hand in front of Chromastone and spoke...

"Fucio Gravis."

...as Chromastone collapses onto the ground. Chromastone tried firing back, but Gwen continued protecting herself in shields projected by mana. This made a lot of ash and dust, Albedo escapes as Big Chill, but she couldn't see him as the dust was preventing her from seeing anything. As the dust finally cleared, Albedo was gone. Gwen looked around in search for the evil Ben, to no avail. She takes a deep breath and sighs, making a departure.

She arrives to Ben reconciling with the Vreedle Brothers, as Gwen clears her throat. "What are you doing?"

Decagon Vreedle responded. "Turns out I'm their distant cousin, as Decagon."

"But what would Ma Vreedle think? Does she know that you're Ben Tennyson?"

"No. But I wouldn't want to ruin the surprise." Decagon Vreedle chuckled.

"Surprise?"

Decagon gets up from the ground and helps the two brothers up from their feet. "I'm going to Undertown to visit the family. I wanna see Ma Vreedle's reaction in person."

In Undertown, Ma Vreedle was cleaning the dishes in the river that separated Undertown into two sectors. She had finished cooking dinner for her Pretty Boy clones, as well as Dodecahedron Vreedle. She hears footsteps from nearby, followed by some voices. Her hat opens, revealing two eyes.

"What have I told you two about sneaking up on-" she spoke, before being cut off.

She turns around to find Octagon and Rhomboid with Decagon Vreedle standing next to them. Her eyes widened, with tears rolling down on her face. She was so happy to see her nephew had returned. "Decagon? You're finally home?"

"Hey now, Aunty. Don't cry on me." Decagon softly spoke, giving her a hug. "Of course I'm home. But I won't be home for long."

She pulled away from the hug, wiping her tears with her sleeve. "Why not? You're not leaving us again, are you?!"

"I have to tell you something, Aunt Vreedle. I'm Ben Tennyson. I have a Vreedle sample inside the Omnitrix, which is why I'm here, alive and well. I was told by the Vreedle Brothers that I'm the Vreedles' distant cousin."

She laughed. "I could've sworn I saw the Omnitrix symbol. Well, you'll still be around to come visit, right?"

"Of course." Decagon spoke, smiling before transforming back into Ben. "I'll always come round to visit the family, even if I don't look like I'm a part of it."

Ben takes a leave whilst waving a goodbye to Ma Vreedle. Gwen was waiting outside, humming to herself. She looks to her side to find Ben walking out. "How did it go? Was she mad?"

"No. She was all emotional. But, both me and her have decided that I'd visit some time in the future." Ben spoke, smiling. Ben knew what he did was right, as the episode ends.
