Cartoon Network mega crossover (Ben 10 reboot self insert x Mar'i Grayson)

Chapter 1 - and then there where ten again

Theodore's POV

It was the first day of summer and Ben was dragging me to a campsite with my grandpa Robert as we where gonna met up with the other two people who are joining us when we get there.

As we arrived I recognized Damian and mar'i "hey it's mar'i and Damian" I said as we parked next to them.

I then hopped out of the rv "mar'i" I said as she looked up and saw me "teddy" she said as she jumped up.

I hugged her "you guys are the ones joining us for the summer" I asked in surprise as I pulled back while her face was red.

Damian and Ben walked forward "we new you too where friends and since Damian and I have been friends since we where your age we thought this would be a good idea" Ben said as Damian nodded.

A few hours later after sun down and the campfire is going low "I'll get fire wood" I say as I rush off into the woods grabbing dry sticks as I go.

Once I get enough sticks I look up and see something crash "woah" I said as I drop my sticks and run towards it.

Bens POV

I was talking with Damian as mar'i was listening to music and not paying attention when I got a emergency call.

I answered the call immediately "Tennyson" azmuth yelled as I stared at him "azmuth what the problem" I asked as he sighed "I was reworking albedos ultimatrix into an omnitrix for your future children like how you asked me to, after I completed it, someone stole it, it's nearing earth and should be landing near you" azmuth said as I heard an explosion.

I jumped up realizing where it had came from "Theodore" I shouted as I rushed off "it landed near that cousin of yours" azmuth said before I ended the call and transformed into Xlr8.

Back to theodore

I had jumped down I to the crater as the pod glowed green "what are you" I asked as it opened up revealing an omnitrix.

I gasped "an omnitrix, cool" I said as I reached out to it with my left hand allowing it to latch on as sixsix landed.

He immediately started talking in his language while pointing guns at me, then Ben showed up and knocked him over "Theodore, got out of here now" he yelled as he continued to fight sixsix and crab who was also here.

So I activated the omnitrix and dialed up my Xlr8 as I slammed down I decided on a name "speed demon" I shouted as I was a child sized version who looked almost exactly like bens except I had shorts not pants.

I rushed back to camp as Damian and mar'i looked at me "bad guys, omnitrix, Ben needs help" I said as I tapped my omnitrix and de-transformed.

Damian grabbed a sword and rushed off as mar'i stared at me "what, do I have something on my face" I asked as she shook her head 'no' "you have an omnitrix like Ben does" she asked as I smiled "yup, wait how did you now Ben had the omnitrix" I asked as she smiled.

She then went on a rant about who her family is as I was in awe "woah, so your a princess" I asked as she smiled and nodded.

Then Ben and Damian returned "hey guys, how was kicking bad guy butt" I asked as they both just plopped down.

Then next day

When I work up Immediately packed everything that I could using speed demon before running around town running past flash.

Flash and his kid ran beside me "who are you" impulse aka flash's daughter asked as the previous impulse now kid flash 20 year old joined us.

I looked at them "I'm speed demon, no normal form hero name yet, I'm 10k's younger cousin" I said as I then ran out of the town that they where in and back to camp.

I de transformed and looked at the others while only had to pack up their tents "morning all, I had a little run after using speed demon to pack up almost everything" I said as Ben and Damian packed everything else up into the rv.

Once we where inside I grabbed my racing suit put it in before grabbing one of bens old ultraben masks "ok hero suit set up now I need a hero name" I said as I sat down with mar'i across from me.

Mar'i then looked at me "why not X" she sis dad I looked at her before looking back at my suit as it did have a huge green x on it "yeah that makes sense as it is the tenth Roman numeral" Ben said as I handed Ben my hero suit.

He looked down at me "put it into my watch like how yours is in your watch" I said as he chuckled and nodded adding the suit mode to my watch.

As I then sat down across from mar'i I looked at her "do you have a hero suit" I asked as she nodded and brought it out from her bag "my name is nightfire" she said before putting it back into the case.

The rest of the morning was us talking about superheroes as grandpa Robert drove with Ben and Damian up front.
