Marvel crosses Star Wars, and everyone attacks the galaxy

Soon after, multiple starfighters began to fly in, firing at the giant Ultron, who either slapped aside or had parts of his body transformed into miniature cannons, shooting them down.

"Well, how is this fair?!" Sam asked loudly in the air after seeing this scene.

"This is too much." said the Black Widow, her face pale.

"Where the hell are those reinforcements?" Anakin wondered aloud in frustration.

"Master Skywalker."

Several turned to see Barriss Offee running towards them with Luminara Unduli and Emma-Gon-Dai and their clone troopers.

"Barriss, Luminara, Emma." Anakin said quickly. "Do you have any good news?"

"The fleets above are trying to push back the enemy, but we are getting word from multiple fronts and bases throughout the galaxy that they are either under or have been attacked by swarms of ships and droids they don't recognize," Luminara informed, shocking the gathered crowd.

"What?!" Ahsoka was stunned. "He attacks everywhere?! How?!

"Where did he get such a large force in such a short time?" Rex asked in shock.

“Knowing Ultron, knowing where he came from…” Black Widow said grimly. “I… wouldn’t be that surprised.

"coming!"

Above, Ultron swung his massive arms violently, destroying another building, which then collapsed towards them.

Instinctively, Spider-Man released a large amount of web to catch the falling debris, and all nearby Jedi Knights collectively used the Force to stop the debris. With this, Peter deployed multiple web grenades, which reinforced his first web, which was now strong enough to temporarily insulate the debris from the building.

“It’s not safe here. We need to move on,” Luminara said.

Those who were under the large net moved quickly to get out from under it.

"Has everyone gone to the shelters and bunkers?" Emma asked.

Barris's expression darkened. "I hope so..."

They felt a gust of wind behind them and they saw Quicksilver running at full speed towards Ultron.

"Pietro, no!" Peter yelled at him in vain.

Quicksilver used his speed and momentum to charge onto the giant Ultron's body, destroying the cannons and turrets that had formed along its massive form.

Eventually, he reached the giant Ultron's head and found his eye.

Quicksilver smashed his vibrating fist into the robot's eye, his arm shaking violently and cracks starting to form around the arm it was embedded in. Quicksilver pushed his other arm in to cause more internal damage.

Soon after, a loud groan was heard and Ultron held a hand tightly over its destroyed eye. Soon after, Pietro tried to jump off Ultron's massive body, but he was knocked out.

Pietro fell to the ground at an extremely fast speed and was picked up by a flying falcon.

"You're so crazy." Sam said, holding Mrs. Soko tightly, and he just groaned loudly in pain.

"Yes, I know." Quicksilver groaned as he felt pain all over his body.

Soon after, multiple starfighters resumed their relentless assault on Ultron, who raised his arms in defense while his entire body's defenses began to repel the oncoming attacks.

"This guy is just too big," Natasha said. "The only way I can see us taking him down is if we send a Venator-class Star Destroyer crashing right into him."

Hearing this, Anakin tilted his head, "It's not impossible..."

"Master? Can't you be serious?" Ahsoka said in shock.

"Do you have any ideas?" Anakin shot back with a wry smile, his Padawan's mouth opened but no words came out, there really was no better solution right now.

"Well, you guys keep figuring it out," Peter said. "I'll do what I do best."

"Wait, what?" Barriss and Ahsoka said in unison.

"Where are you going?" Rex asked, seeing that Peter had already taken off into the air.

"Like I said, doing what I do best," Spider-Man replied. "Pissing that guy off and keeping his attention on me."

After saying that, Spider-Man turned and left.

Anakin did not sit still, he shook his head and raised his lightsaber.

"Come on. The least we can do is try to take this big guy down. Blasters, grenades, lightsabers, anything to attack. We have to take him down or he'll run rampant across the planet."

Without much other noise, the Jedi, Clones, and Avengers resume their attack on the giant Ultron.

They were merciless in their attacks, which finally left a noticeable dent in Ultron's massive body.

The starfighters were also doing their best, trying to keep their distance while firing rapidly at the massive target.

It's just that multiple drones either replace broken parts or repair themselves from the inside, mitigating any visible damage.

The battle could go on for hours as more robots are gathered onto Ultron's massive body.

"Nothing works," cried Quicksilver in frustration, clutching his bleeding arm, with Emma Gon-Dai and Captain Killy beside him.

A Jedi healer was doing his best, but due to the difficulty of treatment, coupled with Pietro's almost non-existent Force powers, the process was quite difficult.

"If this situation continues, the entire city will soon be destroyed." Dai pointed out.

"We have nearly half the Republic fleet here," Kili gritted his teeth. "And it's basically useless."

"Ultron has plans for this." Maximoff said. "He is, after all, an AI supercomputer. Countless plans would have run through his mind like this. Quicksilver snapped his fingers. "But he is an AI based on a human.

"What do you mean?" Dai asked.

"There must be something we can use to take him out." Quicksilver said with a smile. "Weakness of perception, that's what my sister used to call it after we joined the Avengers."

"Any ideas?" Keely asked.

“Not yet, but I’m trying to figure it out.”

As soon as he finished speaking, a large number of ships that were not designed by the Republic suddenly flew in and began to harass Ultron.

"What--"

"Are these our troops?" asked Kili doubtfully.

"Is it reinforcements?" asked a nearby clone.

"It better be, because this is getting ridiculous. It's like the entire planet is out to take us away at this moment." Quicksilver said loudly.
