A/N I don't own KH Nor Age of Ultron. You know why. Anyway, I hope you enjoy it.

After they're touching reunion, Bruce and Betty Joined the other Avengers. They're having a debate about Thor's hammer.

"It's a trick," said Clint.

"No, no, it's much more than that," replied Thor.

"Ah, 'whosoever be he worthy shall have the power!'" mocked Clint, "whatever, man! It's a trick!"

"Please," Thor offered, "be my guest."

"Clint," assured Tony, "you've had a tough week. We won't hold it against you if you can't get it up."

"You know I've seen this before, right?" reminded Clint, "I still don't know how you do it!"

"Smell the silent judgment?" Tony taunted.

"Please, Stark," suggested Thor, gesturing to the Mjolnir, "by all means."

Tony stood from the couch and approached the Mjolnir on the table.

"It's simple physics," remarked Tony, "so if I lift it, do I get to rule Asgard?"

"Yes, of course," Thor nodded.

I will be re-instituting Prima Nocta." He smirked.

"Are you even pulling?" asked Rhodey.

"Are you on my team?" replied Tony.

"Just represent," suggested Rhodey, "pull!" They couldn't even move an inch so they gave up.

Tony wrapped his hands around the handle and attempted to lift the Mjolnir, but it wouldn't budge. He tried again but he couldn't lift it.

"I'll be right back," said Tony.

Tony let go of the Mjolnir and left the room for a bit. Minutes later, he returned with the gauntlet of his mech suit equipped and tried to lift the Mjolnir again but he failed. Tony then calls Rhodey to help.

"Are you even pulling?" asked Rhodey.

"Are you on my team?" replied Tony.

"Just represent," suggested Rhodey, "pull!"

They attempted to pull at the hammer a few times before giving up. Bruce tried to lift it but failed. Betty patted his back in comfort. Sora tried but not successful. Tony gave a laugh.

"Not even the Keyblade's chosen one could lift the Hammer." He chuckled as he took a sip of his beer. Sora glared before sitting down with his wife. Cloud, as strong as he is, pulled it but no avail. Now it's Steve's turn.

"C'mon, Cap. You can do it." Sora cheered. Hearing his encouragement, Steve grabs the handle and pulled on it. Unfortunately no budge. Sora snapped his fingers then it was Kairi's turn. This time though she barely moved an inch but like all the others, she couldn't move it. She then turns to other female Avenger.

"Natasha, would you like to try?"

"Oh, no," Natasha declined, "it's not a question I need answered."

"The handle's imprinted, right?" clarified Tony, "like a security code. Whosoever is carrying Thor's fingerprints is, I think, the literal translation."

He comments, "yes. Well, that's a very, very interesting theory. But, I have a simpler one."

He picks up Mjolnir and points to his friends. "You are not worthy." They all groaned at him then they suddenly heard a loud screeching noise. Once it died. They then see one of Tony's iron legion robot limping.

"How could you be worthy?" demanded the robot, "you're all killers."

"Stark?" Steve looks at him with a question.

Tony pulled out his smart phone.

"Jarvis?" he whispered. But Jarvis didn't answer.

"I'm sorry," said the robot, "I was asleep, or I was…a dream."

"Reboot Legionnaire OS. We got a buggy suit." Tony said trying to contact JARVIS.

"There was this terrible noise. And I was tangled in... In... Strings. I had to kill the other guy. He was a good guy.T" the drone said.

"You killed someone?" Sora asked.

"There was this terrible noise," continued the robot, "and I was…tangled in…strings."

"Who sent you?" Sora asked. The robot then played an earlier recording.

I see a suit of armor around the world… Bruce recognized that recording from earlier.

"Ultron?"

"In the flesh."Ultron said proudly."Or, no, not yet. Not this...chrysalis. But I'm ready. I'm on a mission."

"What mission?" Kairi asked.

"Peace in our time. To take over... Kingdom Hearts." Sora's eyes narrowed.

"Why Kingdom Hearts?" He asked the drone.

"Ah... Sora, the Keybearer. Married to the Princess of Heart, Kairi. It's so the darkness can take over... and once darkness takes over... peace will be restored."

"Yeah, with hurting innocent people. Turning into Heartless!" Kairi exclaimed.

"We all must make sacrifices." Ultron replied as multiple Iron Legion drones under Ultron's control crashed through the walls and attacked everyone. Sora and Kairi brought out their Keyblades and Jumped on a legion. Kairi cuts through Some heads while Sora used his Blizzrardga, freezing them then slashing through them.

Suddenly, two more Legionnaire robots burst from the wall and charged in to attack. Thor swung his Mjolnir at one while Maria pulled out her gun and fired it at the other. Thor swung his Mjolnir at one while Maria pulled out her gun and fired it at the other. Thor swings his hammer at another drone, sending it flying back. A Robot shot at Sora who wasn't looking and would have hit him if his wife didn't blocked it with her Keyblade. She then does a Sonic Blade against one drone to another. One drone tried to blast Clint, but he takes cover under a table. She shoots an arrow straight to his heart, killing the robot. Bruce and Betty ducked behind the table. She turned to him.

"Don't turn green." She begged.

"I won't." He smiled. Natasha grabbed a gun under the floor and shoots more Legionaires.

one drone then grabbed Loki's scepter and flies off.

"He's got the scepter!" Sora pointed.

One drone starts throwing blasts as Natasha starts firing her pistol. One of the bots had gone to the lab and taken the sceptre leaving the building. Tony got up, grabbing a metal prod running back to the fight. Steve jumped onto a bot punching it and being slammed against a wall and thrown to the ground.

"Hey Cap!" Clint shouted as he throws Cap his Shield and he launch himself at the Iron Legion armor. Sora

"That was dramatic. I'm sorry, I know you mean well. You just didn't think it through.", Ultron said with a sigh. "You want to protect the world, but you don't want it to change. How is humanity saved if it's not allowed to...evolve?" He then picks up on of his destroyed fellow legion. With these? These puppets? There's only one path to peace: The Avengers' extinction." Thor throws off his hammer and smashes Ultron to pieces. After Thor destroyed his body, Ultron began singing. "I had strings, but now I'm free. There are no strings on me, no strings on me." Ultron later uploaded his consciousness on another body. The Avengers goes to Bruce's lab and discover the horrors of Ultron's actions where he killed JARVIS.

"All our work is gone. Ultron cleared out, used the internet as an escape hatch." Bruce said.

"Ultron." Sora said while clenching his fists.

"He's been in everything. Files, surveillance. Probably knows more about us than we know about each other." Kairi said.

"He's in your files, he's in the Internet. What if he decides to access something a little more exciting?" Rhodey said, fully recovered from the attack.

"Nuclear codes." Hill said.

"And even Kingdom Hearts." Kairi murmured.

"How can he get there, though?" Asked Steve. "Doesn't he need The X-Blade to unlock it?"

"Yeah...he could make his own custom X-Blade." Tony said pretending to hold a Keyblade and aim at the door.

"... that's not far off, Tony." Kairi said. Tony looked down with bewilderment.

"Say what?"

"I Can feel his heart. It's part of being a Princess of heart. He has one strong enough to wield the X-blade. One that is similar to Xehanort." Sora raised an Eyebrow.

"How do you know, Honey?" He asked his wife Kairi sighed.

"Because... A few weeks ago. I had a terrible nightmare of us battling a figure like Ultron. He had a X-Blade and it was custom made but somehow he made it to where it opened. I have a feeling it's gonna come true that he will make his own custom X-Blade."

"But he needs the 7 Princesses of heart, too." Sora countered. Tony calmed down after hearing it.

"Fortunately though, They're in your universe and I don't think he can enter there. I made him smart but not wise."

"It doesn't matter, he wants us all dead." Natasha spoke.

"He didn't say dead. He said extinct."

"He also said he killed somebody." Clint pointed out. Mara looked around but sees no body.

"There wasn't anyone else in the building." She said.

"Yes, there was." Tony said as he brings up the last 3D image of JARVIS.

"This is insane."Bruce looking sadly at image of Jarvis.

"Jarvis was the first line of defense. He would've shut Ultron down, it makes sense." Cloud then comes in and grabs Tony on the throat.

"Thanks to you, you doomed us all."

"Come on, doomed is such a harse word." Tony said, trying to gasp for air.

"I have more than words to describe you, Stark." Cloud said.

"Whoa, whoa. Cloud, calm down." Sora put his hand on Cloud's writst. "I'm mad at Tony, too but trying to kill him isn't gonna solve anything."

"Sora's right." Steve agreed.

"The Legionnaire, drop him!" Steve said. Cloud hesitated then he places Tony down.

"Genie's out of that bottle. Clear and present is Ultron." Natasha said.

"I don't understand." Dr. Cho said getting everyone's attention. "You built this program. Why is it trying to kill us?"

Tony didn't reply and started laughing. Bruce tried to get him to stop.

"You think this is funny?" Cloud asked.

"No. It's probably not, right? Is this very terrible? Is it so...is it so...it is. It's so terrible."He replied looking at the Avengers.

"This could have been avoided if you hadn't played with something you don't understand." Thor said.

"No. I'm sorry. I'm sorry. It is funny. It's a hoot that you don't get why we need this." Tony said.

"Tony, maybe this might not be the time." Bruce said.

"Really? That's it? You just roll over, show your belly every time somebody snarls?" Tony said.

"Only when I've created a murder bot." Bruce said.

"We didn't. We weren't even close. Were we close to an interface?" Tony asked Bruce.

"Well, you did something right. And you did it right here." Steve said. "The Avengers were supposed to be different than S.H.I.E.L.D.."

"Anybody remember when I carried a nuke through a wormhole?" Tony asked.

"Yes and we are all grateful for that." Kairi answered. That earned a smile from Tony.

"A hostile alien army came charging through a hole in space. We're standing 300 feet below it. We're the Avengers. We can bust arms dealers all the livelong day and destroy Heartless, but that up there, that's... That's the endgame. How were you guys planning on beating that?" Tony asked.

"Together." Steve answered with his arms crossed.

"We'll lose." Tony said.

"Then we'll do that together, too." Sora said.

"They're right." Kairi said. "We're all in this together. As long as we can find Ultron and stop him before he eithers enter Kingdom Hearts or destroys the Earth. We may have made some mistakes but we can fix them."

"Kairi's right. Steve said. "Ultron's calling us out. And I'd like to find him before he's ready for us. The world's a big place. Let's start making it smaller."

"Right." He draws out his Keyblade. "So let's find him."

Uh-oh, Ultron is now a living conscious. What will our heroes do? We'll find out next time. Until then, see ya.
