A/N: Marco will be wearing Ben's Omniverse T-shirt, but with no 10 on the middle

We see the heroes in their classroom and boy was it boring

"Russo-Turkish wars, series of wars betweenRussiaand theOttoman Empirein the 17th–19th century. The wars reflected the decline of theOttoman Empireand resulted in the gradual southward extension ofRussia'sfrontier and influence into Ottoman territory..." The History teacher explained, as he gestures to the chalk board, with a drawing of a Russian General

Marco was paying attention, Janna was playing with her pencil and Star was asleep

"Hey, Doesn't this historical rivalry lesson remind you of something?" Janna whispered to Marco, trying to kill the boredom

"Janna not now. I'm trying to listen" Marco whispered, as he listened to the teacher's explanations

"But this lesson is soooo boring" Janna complained

"Ahem! Something you would like to say to us Janna? Marco?" The History Teacher called out, while adjusting his glasses

"Oh, we were just talking about Marco's old rival: Kevin Levin" Janna said, as Marco facepalms

"Rival? What kind of rival are we talking about?" The History Teacher asked, genuinely curious

Janna was about to answer but Jackie interupted

"Wait, Kevin Levin? As in the guy that used to bully Marco? How is he Marco's rival" Jackie asked Janna

"Alright guys, story time" Janna said while grabbing a book from her backpack that said Memory Book which was filled with pictures of Her and Marco's adventures

"Alright, we get to here a story on Marco and Janna's summer!!" Justin exclaimed as the rest of the class were excited

Star wakes up at what Justin said and got excited aswell

"Hey! What's the story about?!" Star asked excitedly

"Marco's rival"

"Marco has a rival?!" Star exclaimed

"Marco can you start us off please" Janna said, as she gestures him to tell the story

"Alright, I'll tell but after this, everyone must get a grade over 80 or else when I tell a story the people who got under 80 must stay out. Deal?" Marco said

"Deal" Everyone said in unison


FLASH BACK START

Marco's PoV

We were at New York and our R.V. broke down and we had to go outside.My Dad checked under the R.V. and found out what the problem was.

"Hmmm, I see the problem, it's a leak and we don't have anything to patch it up with. Marco, Janna can you 2 please go to the nearest market and buy some butyl sealing tape while me and your mom find a hotel to stay in, I need to take an actual shower. I'll message you the location" My Dad said to us.

"Oh, and can you buy some groceries aswell" My Mom added, Giving us a list on what to buy

"Sure thing mom/Sure" Me and Janna said as we left.

FLASHBACK PAUSE


"Wait so your parents just left you alone to get some groceries?" The History Teacher asked, questioning Marco's parent's decision

"Well I had The Omnitrix so we were pretty much safe as long as I had this thing" Marco replied, gesturing at the watch

"Ok continue" The History Teacher said, gesturing him to continue


FLASHBACK RESUME

When we arrived at the mall, we read the list and searched for the stuff My Mom wanted us to buy.

SMALL TIME SKIP

Me and Janna finished and My Dad already texted us the place where we're going to stay, but before we left, I noticed a fammilar looking person. He had Black long hair, a brown jacket and an inch taller than me. It was none other than Kevin Levin, my old bully


FLASHBACK PAUSE

"Hey, wait! Who IS Kevin Levin other than his bully" Justin asked

"Well he may be a bully, but deep down he has a good heart" Marco said with a smile


FLASHBACK RESUME

"Hey, is that Kevin?" I asked Janna

"I don't know. There are a lot of kids that got long black hair and wear brown jackets" Janna said, not sure if it was Kevin or not

Kevin then kicks a stack of cans

"Ok that's him" Janna said, now convinced it was Kevin

"Yeah, and now it's payback time" I said as I activates the old Omnitrix

the old Omnitrix looked like a large wristwatch, primarily black and grey in color, with a grey (or black) dial in the middle (like a watch face) which has a green hourglass shape on it. It has a circular tube. When Marco selects his aliens it shows the alien's silhouette.

FLASHBACK PAUSE


"Wow, that's what the old omnitrix looked like? Looks pretty retro" A student said, looking at a picture of the omnitrix before it got recalibrated

"Yeah and look at it now. More futuristicy and all green" another student said

"can we continue the story now?"

"Yes"


FLASHBACK RESUME

I slapped the omnitrix and after a bright green flash, came out Stinkfly

Stinkfly has a bug/insect body and four insect-like flat legs with two arms, whose hands are human-style ones with three clawed fingers. He has four pedunculated eyes that are pretty small. These eyes are linked directly to the sides of his huge head. His wings are light green and very fragile with lines on them, and his limbs are a brown-greenish color. His tail is an ultra sensitive receptor, making it like an antenna. He wore a white sleeveless jumpsuit with black lining which covered most of his body including his head and tail, his hands had a black coloration similar to fingerless gloves, and his eyes were yellowish-orange. He wore the Omnitrix symbol on the top of his forehead.

FLASHBACK PAUSE


"ewwwww" All the girls said excluding Janna

"Hey! that alien can be pretty useful, you know!" Marco said, defending one of his original transformation

"Oh yeah? Where is he now?" Brittney asked, arrogantly

"He's... currently locked" Marco said embarrassed


FLASHBACK RESUME

Stinkfly flew and landed on a shelf

"Alright Kevin. Your about to taste some of your own medicine" I said, as I fired goo from his...eyes? It was about to hit Kevin, who was chack out some pillows, but Kevin used a pillow to block the goo and did a back flip

"Why hello there buddy. It's been a while. I love the new look, especially the design" Kevin said, as he pulls up his sleeve to reveal another omnitrixIt looks like a makeshift replica of the Omnitrix's model, with the dial symbol turned red and appearing in half, resembling a letter 'K', and with the addition of four metal protrusions ending in red lights.

"ANOTHER OMNITRIX?!?!?!?!?!?" I exclaimed, surprised that my bully possibly had the same powers I did

FLASHBACK PAUSE


"Cooooolll" Almost everyone awed at the image of the Kevin's Omnitrix

"So what's the difference between his and yours, beside looking cooler" Star asked Marco

"I was getting to that" Marco said, annoyed that everyone said his omnitrix looked retro and Kevin's OMNITRIX looked cool


FLASHBACK RESUME

"You call yours Omnitrix, but I call mine ANTI-TRIX!!" Kevin exclaimed as he slammed his hand down the newly dubbed Anti-trix

After a red flash he transformed into a hulking, broad-shouldered alien covered in black metallic armor with dark red pearlescent on his upper arms, claws, lower torso and legs and red armor plating on his back, shoulders, and head. He has thirteen golden spikes, fiveon his head, six on his back, and one on each forearm. His exposed face and forearms are mostly white, with glowing red eyes. He has four claws on both of his hands and grey lips.

He wasn't Cannonbolt, he was Wreckingbolt

FLASHBACK RESUME


"He looks a lot like Cannonbolt but more sinister." Jackie said

"Yeah, he kinda does" Star said, agreeing with her


FLASHBACK RESUME

After transforming he jumped right at Stinkfly and turned into a ball, almost hitting him but Stinkfly dodges it with ease. Kevin landed very poorly on top of a metal cage, full of bouncy balls

"Seriously? How long did you have that 'Anti-trix' because it seems like your a little out of practice" I said, tauntingly

He stood up and wiped his face

"Okay, I admit, I haven't had it long. Few nights ago, I had this crazy dream, it was so vivid. I had to draw down what it showed me. No way I wasn't gonna build it. I wasn't even sure what it was for. But it didn't take long to figure out, and with few minor modifications of my own, I got something pretty awesome." Wreckingbolt said

"Modifications? What kind?" I asked him

"Let me show you" he said to me as a kicked a ball towards me so I dodge it and he also threw himself at me but I dodged it aswell and he landed on his face

"It seems like your modification have a bit of a glitch" I said to him

FLASHBACK PAUSE


"Alright, now can you tell us what the difference between the 2 devices" Jacki asked

"Well you see, my omnitrix contains healthy alien DNA, but his Anti-trix's alien DNA is contaminated, thus mutating his transformations, into battle-ready counter parts of my aliens" Marco explained

"So it's not only cool looking, but it's also slightly better" Brittney said, smugly

Marco growled at this but continued the story


FLASHBACK RESUME

My Omnitrix started to beep, warning me it was about to time out

"Oh no, not yet!" I exclaimed as I fly far away from Kevin as I can

When my Omnitrix finally timed out, I fell and landed on my butt

"Ow, ow, and more ow" I said to myself

"WHERE ARE DIAZ!!! COME OUT AND PLAY!!!" Wreckingbolt exclaimed as, I hid from behind a shelf

"Come on, recharge already!" I told my omnitrix

"There you are!" Wreckingbolt said and charged at me but I dodged and he hit the wall

I ran and ran until I eventually lost him. After a few minutes, my omnitrix finally recharged and I activated it, transforming into Four Arms

"Alright Kevin! Round 2!" I said, while cracking my knuckles

"With pleasure" Kevin said, charging from behind me, making crashes into a shelf

"Okay Kevin, let's take this outside" I said to him as I leaped towards him and grabbed his arm, throwing him at a wall, tearing it down

I jumped out of the hole I made, using kevin, but when I got there I saw Wreckingbolt in the ground, standing up.

"Sorry Diaz, but there are some places that I need to be, so I'll see you later" Wreckingbolt said before transforming in an alien that is similar to XLR8 and ran at mach speeds

"Wait, he has Master Control?" I said, somewhat jealous of Kevin

FLASHBACK END


"After that I meet him on a weekly basis, either fighting or working with him to beat the big bad. But when he and Vilgax teamed up, he discovered he was the one that sent him that dream, and tried to take Kevin's Anti-trix while the three of us were at the Null-void, an integalactic prison, but when we were about to escape, Kevin told me to run and leave him behind, because he'd rather die than let Vilgax take over the world, proving he has some good in him" Marco said with a sad smile

Everyone was surprised that a bully would do something so selfless

"Can we go back to the lesson now?" Marco said, trying to change the subject

"The class has been over for 5 minutes now" the teacher said, with a bit of tears on his eyes

"Well that story was a waste of time" Marco said with a deadpanned expression


A/N: Sorry for the terrible chapter but I have been on a lot of stress lately so I probably won't update for the next few days
