A/N I don't own KH nor the Avengers but I hope you enjoy

Sephiroth drew out his sword on Cloud.

"Cloud, you'll never defeat the darkness because you refuse to let go of your past."

"Shut up!" Cloud barked and charges at the one winged angel, ripping a hole of out in the wall of ceiling. Thor turns to Sora.

"Should we help him?" Sora shook his head at Thor's question.

"Like Cap says. Ultron's fight is ours. Sephiroth is Cloud's." Thor looks at Ultron holding the queen of Arendelle. Sora turned over to his wife.

"Kairi, you and Tony take care of Ultron to save Elsa. We'll take care of the twins." Kairi nodded as she and Tony get into battle mode against Ultron. Ultron who was carrying Elsa, glared at the two heroes. Tony glided to him and punches him. Ultron recovered, still carrying the Princess of Heart in his arms. However he didn't expect Kairi to sneak from behind and grabbing Elsa and takes off. He didn't notice it until he felt air. He looks to see Elsa was gone. He searched until he sees the Princess of heart flying her out. Ultron begans to chase her but was stopped by Tony who was grabbing his leg.

"Good work, Kairi." Grunted Tony. "I'll take care of tin man here. You take her to the quinjet." Kairi nodded and flies out. Ultron tries to chase her but couldn't let go of Iron Man's grip. Ultron sighs in frustration.

"If I'm gonna get the queen, I might as well kill you, Stark."

Back at the quinjet, Bruce and Betty tries to contact any of the Avengers.

"Guys, is this a code green?" He asked. Nobody answered. Bruce looked at his girlfriend.

"Betty... I'm gonna see if they need me. You stay here." Betty nodded and walks over to hug him.

"Be careful." She said. Bruce nodded and kissed her cheek before he seeks off. After he left, Betty sees Kairi coming in holding a woman in a blue dress. She wasted no time setting the bed.

"What happened?" She asks Kairi who puts the woman in the bed.

"Long story short, an old enemy of Cloud named Sephiroth kidnapped one of the princess of hearts. This is Elsa. I saved her from Ultron's clutches." She looked around to see that they're alone. "Where's Bruce?"

"He went back to help the others." Kairi's eyes widen.

"What?"

Meanwhile back at the ship, Wanda was sneaking behind Thor and uses her manipulation powers on him. He looks around in conufsion.

"Thor! Status?" Cap asked.

"The girl tried to warp my mind." Thor tells him while taking down some Heartless. "Take special care, I doubt a human could keep her at bay. Fortunately, I am mighty..." However Thor's mind starting to trick him as he sees himself back at . He looks around in confusion. Meanwhile both Cap and Sora were fighting more Heartless and men but Pietro ran past them then Wanda uses her power on both of them. They suddenly have new visions. Wanda sees Natasha and uses the opportunity to use her powers on her. Ultron was grinning evilly as his sentries took the vibranium.

"This is going well." He said.

Meanwhile, Clint was shooting arrows at Klaue's men. He shot one arrow, after another. He shoots an arrow of shockwaves on another. At first Wanda is using her advantage to take control of his mind but Clint stopped her and puts an electric arrow on her forehead.

"I've done the whole mind control thing before. Not a fan." Clint said, referencing the time

Pietro ran forward, launching Clint through a large window before grabbing his sister and sprinting away.

"Yeah, you better run." Said Clint as they run off. He then turns on his commlink. "Whoever's standing, we gotta move." He didn't get an answer. "Guys?"

Natasha was having a vision of her past. Back when she was being trained to be an assassin at the red room.

"What if I fail?" She asks her supervisor Madam B.

"You never fail." She then uses her gun to kill a man. She later sees herself against another assassin who is choking her during her training. She then manages to take him out.

"Sloppy. Pretending to fail. The ceremony is necessary for you to take your place in the world."

"Exactly." Madame said. She then takes Natasha to a medical bed as she prepares to sterilize her.

Cap meanwhile sees himself back in the 1940s. He was walking around in confusion. He then sees.. Natasha in 40s getup with a smile.

"The war is over, Steve. It's time to come home." Steve looks at her in confusion.

Back at Thor's vision in Asgard. He is sees his best friend Heimdall who has eyes that is white.

"Is it him? Is that the first son of Odin?"

"Heimdall, your eyes." Heimdall puts his hand on his neck.

"Oh, they see everything. They see you leading us to Hel." He growled then he started to strangled Thor.

"Stop... I can still save you." He grunted.

"We are already dead. Can you not see? You're a destroyer, Odison." Thor's vision changes to a stone and a pair of red eyes.

Sora's vision is him back at Kingdom Hearts. Only this time he and Kairi are having a tough time with Xehanort... or someone else. He couldn't tell. The figure aimed his Keyblade at Kairi but Sora blocked his attack before he could hit. The enemy then does a similar fighting pose like Riku did. He hears him chuckled.

"It ends now, Keyblade Master!" He said in a deep distinct voice as he charges them.

Back in reality, Wanda was holding her forehead, recovering from the electric shock Clint gave her.

"No, I'm alright. I want..." Wanda breathes and sees the quinjet "I want to finish the plan, I want the big one." They both look at Bruce Banner leaving the quinjet. Meanwhile Tony was chasing Ultron down the shipyard. He then shots him down causing Ultron to crash near a ship.

"Ah, the vibranium is getting away." He taunted. Tony aims his missile at him.

"And you're not going anywhere."

"Of course not, I'm already there. You will catch on. But first you might need to catch Dr. Banner. But don't worry. I'll get the princess of Heart, later." Tony snarls and fires his missile, destroying Ultron's body. He then uses his comlink.

"Kairi, you there? Come in."

Meanwhile Kairi and Betty are tending the unconscious queen by putting a washcloth on her forehead. She hears her commlink.

"I'm here. What do you need, Tony?"

"Listen, Ultron escaped. The witch pulled a spell on Banner. He's gonna go on a rampage." Both Kairi and Betty widen their eyes. They know what will happen when the Hulk gets really mad.

"Listen Kairi, you have to stop him. I have to help the others. I think she put them under a spell, too." Kairi's eyes widen.

"But Tony, my armor's..."

"I don't mean your regular suit. I mean the... Hulkbuster." Tony said. Kairi gasped silently.

"But Tony, It hasn't been tested yet." She exclaimed.

"Well now it has. You have to do it, Kairi or else the Hulk will kill innocent people. Kairi looked at the city. She hears the Hulk growls. Kairi stared at the queen for a minute then she looks at Betty standing near her. She opens the door then turns to Betty.

"Betty, I'll stop Bruce. You stay here with Elsa. If Tony comes by with the others let them in." Betty nodded and continued to dampen Elsa's forehead. She puts back her Iron Woman suit and runs out of the Quinjet.

Yep, Kairi will be the Hulk buster this time. No matter what, I always want her time to shine. But Where did Cloud and Sephiroth go? We'll see. I hope to post it sooner before May. Until then, enjoy this chapter. Take care.
