This is the first crossover I have ever done. So I want the readers to know that I don't own Ben 10, Lab Rats, Mighty Med, Kickin' It, Yu-Gi-Oh Series, Skylanders, or Bakugan Battle Brawlers. I only own the idea of the Dueltrix, Bakutrix, and Skylatrixes. Also the heroes in here are all 16,and Ben has a little personality change.

Prologue: The Birth

(Davenport Residence)

The Davenport siblings are training in their new underground lab starting with Chase Davenport on target practice.

''Remember Chase, find the correct angle to shoot the moving targets.'' said Donald Davenport as he sets the targets. The targets start moving around the room. Chase calculates the speed and trajectory before he readies his force field ball in his left hand.

"You got it, Davenport.'' said Chase as he prepares to fire. Before he did, he instantly got teleported out of the lab.

''CHASE!'' yelled the whole family when they saw him teleport.

(Mighty Med)

Kaz and Oliver are studying in the training room while Skylar Storm was training her powers. A big hologram that says "PERFECT" appears in front of Skylar when she finishes her training.

"Uh, is it just me, or is Kaz actually studying?'' asked Skylar as she approaches the duo.

"My parents said if I don't bring my grades up, they'll return my comic collection and ground me for a few months" answered Kaz without looking away from his book.

"Can you blame them Kaz? You're always reading comics in-between assignments" said Oliver.

"You're right, Oliver. It's not like my problems can just disappear" said Kaz before he got teleported out of the hospital.

"KAZ!" yelled both Skylar and Oliver when they witnessed their friend disappear.

(Wasabi Dojo)

Jack and Kim are standing on opposite sides of the dojo mat while Jerry and Milton watch from the lockers.

"Alright guys, no backing down, you got it?" said Rudy as he walks between them.

"Yes, Sensei Rudy" said Jack and Kim.

"AAAAANND BEGIN!'' exclaimed Rudy as he walks out of the mat. Jack and Kim charge at each other and leaped to kick. Before they came in contact, they got teleported out of the dojo.

"JACK! KIM!" screamed out the remaining martial artists when they saw their friends teleport.

Prologue, Part 2 (Last time on The Galactic Defenders)

We witness Chase teleport from the underground lab. Next we witness Kaz disappear ironically because of his big mouth. Finally, we see Jack and Kim teleport from the dojo. The witnesses wondered what happened to their missing friends.

(Azmuth's Lab)

Chase, Kaz, Jack and Kim appeared in the lab in a flash of light. They stopped their interrupted actions to scan their surroundings.

"Jack, where are we?" asked Kim as she approaches Jack.

"I don't know, Kim." answered Jack while continuing to scan his surroundings.

"Oh just great. The only time I decided to study and this happens." said Kaz angrily.

"This is … AMAZING! I'm standing in a highly advanced lab with amazing technology." shouted Chase as he approaches a desk to search for documents.

"DON'T TOUCH THAT!" shouted an unknown voice. All known eyes in the room look at where the voice is coming from. When they saw who owned the voice, the four teens stare unbelievably at the source. It was Azmuth.

"Is that a Grey Matter?" asked Kaz amazed.

"A Grey what?" asked the three clueless teens.

"You never heard of Grey Matter?" asked Kaz. The others shook their heads.

"Grey Matter is the smartest form of the world-famous superhero, Ben 10" answered Kaz.

"At least one of the chosen wielders know me better." said another unknown voice. Stepping out of the shadows is none other then Ben Tennyson, wielder of the Ultimatrix.

"Oh my god, BEN 10!" exclaimed Kaz since he is the only fan boy in the room.

"In the flesh." said Ben. Kaz went up to him and shook his hand.

"It's an honor to meet you, Ben 10." said Kaz as he finished the handshake. Jack recalled what Ben said and approached him.

"What do you mean 'Chosen Wielders'?" asked Jack. Ben made a 'follow me' hand gesture. Everyone followed him to another room where there are three more people standing by four devices that resemble the Omnitrix, each with a different design and color scheme.

"Allow me to introduce myself. I am Azmuth, the smartest being in three, possibly five galaxies." introduced Azmuth before he moved on to the other three.

"This is Maximillion Pegasus, creator of Duel Monsters, and before you ask why you never heard of it, that is because it is from another universe, like he is." stated Azmuth. The teens stared at him wide-eyed while Azmuth introduced them to the blue haired girl.

"This is Fabia, alien princess from Nethia, which is also from an alternate universe." stated Azmuth. The teens stayed wide-eyed, but switched to her while Azmuth introduced them to the old man.

"He is Eon, a portal master, from Skylands." stated Azmuth knowing their reaction. And he was right.

"I already know about you four and your protected secrets. Chase Davenport, you weren't born like normal humans because Douglas Davenport, your birth father, has genetically engineered you for experiments with the chip on your neck that makes you bionic." said Azmuth.

"How do you know who I am?" asked Chase.

"Hello, haven't you heard what I said? He hacked into every computer system to search for you with a device he made. Grey Matters are incredibly smart despite their size." stated Kaz.

"I'm not a Grey Matter, I'm a Galvan. Ben only named his Galvan form Grey Matter. (sighs angrily) Let's move on. Kaz, 2 years ago you started to work in a superhero hospital known as Mighty Med." said Azmuth.

"Hey, that's supposed to be a secret!" complained Kaz.

"Don't worry, we won't tell anyone else unless they are from another planet. Now, let's move on. Kim Crawford, you used to be a Black Dragon until you saw them try to cheat in a tournament by injuring Jack Brewer's leg." said Azmuth.

"That's right. If I knew they were such jerks from the beginning, I would have never joined the Black Dragons." said Kim.

"You have a good heart, Kim. And finally, Jack Brewer. Your grandfather taught you martial arts since you were little. When you moved to Seaford, you joined the Wasabi Dojo the day before Kim did." said Azmuth.

"How do you know about my grandfather?" asked Jack.

"DIDN'T YOU HEAR WHAT I SAID?!" yelled Kaz annoyingly.

"Oh right. Sorry, Kaz." apologized Jack.

"But the introductions still didn't answer Jack's question about the 'chosen wielders'." stated Kim.

"I was getting to that, Kim. You see what's on the table?" asked Azmuth. The teens looked at the Omnitrix-like devices on the table and nodded yes.

"You four are the chosen wielders." stated Azmuth.

"WHAT?" yelled the four teens.

"Let me take it from here, Azmuth. The chosen wielders are the five people who are chosen from the creators." said Fabia.

"I'll start things off. Kaz, my boy, come closer please." said Pegasus. Kaz approached him when Pegasus took out a black Omnitrix with a grey rectangle with a darker grey vortex in it as the symbol.

"Kaz, you are chosen to wield the Dueltrix because you always trust your instincts. And before you ask what the Dueltrix is, I'll tell you. It's a device that allows the wielder to transform into various Duel Monsters, creatures that are sealed in the Shadow Realm." stated Pegasus.

"My turn. Chase Davenport, you are chosen because you are the smartest human on the planet and you put that knowledge to good use all time, and the device that you are chosen to wield is the Bakutrix, a device that allows it's wielder to transform into various Bakugan, creatures that only exist in my universe that are based upon the Attributes, the 6 elemental powers that Bakugan possess, and it also lets you change the Attribute along with the powers of the form you choose." said Fabia as she took out a blue Omnitrix with the Bakugan symbol instead of the hourglass symbol.

"And last, but not least, Jack and Kim. Jack is chosen because he is the wisest black belt on the planet, and Kim is chosen because she has the greatest heart of gold that I have ever seen. The devices you two are chosen to wield are the Skylatrixes. Jack has the one with male Skylanders and Kim has the one with female and unknown gender Skylanders. Skylanders are magical creatures that protect Skylands from the darkness." said Eon when he represented two Ultimatrix-like devices with a screen besides the dial. One is red, and the other is yellow.

"Wait, didn't Fabia say there are 5 chosen wielders?" asked Chase. Azmuth nodded.

"Well, there are only four chosen wielders here, so where's the fifth?" asked Chase.

"You're looking at him." smirked Ben Tennyson. The others are shocked (except Kaz) that Ben 10 is the fifth chosen wielder.

"Anyway, this is a huge responsibility, so you can choose whether to be a hero or not." said Ben.

"Well, that's a no-brainer. I'm in!" said Kaz excitedly.

"Me, too." said Chase.

"Me three." said Jack and Kim simultaneously.

"All right then. Attach the devices to your left wrists." said Azmuth. The teens did that with the chosen devices and the devices said the same thing.

DNA LOCK ACTIVATED

"Let me guess, the DNA Lock is to prevent anyone else to try to steal them from us." stated Chase.

"That's right, Chase. You really are the brains of the group." said Ben.

"Attention all PLUMBERS closest to Earth, D'void escaped from the Null Void and is wreaking havoc in Bellwood." called out the PLUMBER H.Q from Ben's Ultimatrix.

"Guess we take the new powers for a test drive, Ben 10?" sighed Kaz. Ben nodded yes.

"Alright, team. IT'S HERO TIME!" exclaimed Ben when they ran out of the Lab.

The Galactic Defenders era begins. If you want to see them use their new powers, say so when you review.

P.S: This is a re-write of the two shorter chapters put together.
