**Crossing into the Flash Universe**
"Miss Alex Rivers, what would you like to drink?" Pepper Potts asked.
"Just a glass of juice, thank you." Alex Rivers adjusted her nano battle suit to transform into a beautiful blue long dress.
"Oh! Is your outfit a nano battle suit? How did such advanced technology come about, that it can be freely equipped?" Tony Stark, ever curious about advanced technology, couldn't help but inquire. He had many questions about Alex.
Alex smiled, set her glass down, and explained, "This is a product developed by my family over generations—alien technology that transforms according to my thoughts."
Tony's eyes lit up with excitement. "That's amazing! Can I study its structure?"
"System, what happens if a small part of the battle suit is cut off?" Alex asked internally.
"Nothing will happen. The cut-off part will lose its activity and turn into ordinary material. A small amount of system points will be deducted."
Seeing Alex's hesitation, Tony quickly made an offer: "I'll give you a villa, plus one hundred million, just for you to cut off a small part."
"Alright, but I can't guarantee you'll be able to research anything from it."
"Deal!"
Tony, fascinated by new scientific advancements, felt like he'd struck gold.
"Okay… deal," Alex agreed.
"Host, you're really treating Tony like a big sucker," the system quipped.
"Ding! A small piece of nano material consumed, 100 points deducted."
"System, you're too kind."
"There's something even kinder. A movie that was shown in the world you lived in before is now on sale for a limited time. For 50,000 points, you can permanently unlock 'Flash: Double Flash Attack' and travel to this world at will."
...Tony eagerly took the small piece of material Alex tore off, ready to study it.
Alex told Tony, "I suddenly have an urgent matter to attend to and need to travel to another universe. We'll see each other again."
"Okay, then we'll talk next time. Pepper, please see Miss Rivers off, and transfer the villa and cash to her name." Tony was secretly pleased with Alex's departure, eager to begin his research.
"No need to see me off, I'm leaving!" Alex smiled mysteriously, commanding the system internally to initiate the crossing. A blue portal opened, revealing a scene from another world. Alex stepped in, and the doorway closed behind her.
Tony was stunned. Had someone just crossed universes in front of him?
"Wait, she just said she was going to another universe? She wasn't joking?"
"Oh! My God!" Pepper exclaimed in disbelief.
"Jarvis, search the entire world for information on Miss Rivers' appearance, see if she's still in this world, keep an eye on her news, and report any important information immediately."
"Yes, sir."
Inside Kamar-Taj, the Ancient One sensed the unusual spatial disturbance near Tony and realized that Alex had vanished from this world.
"Superwoman, it seems I'll have to talk to you next time."
...**Flash: Double Flash Attack Universe**
(If you haven't seen the movie, or don't want to, you can wait to Chapter 12; it won't affect your understanding of the subsequent plot.)
After a fierce battle, Shadow Superwoman was defeated by General Zod, and Batman, in his Batwing, courageously sacrificed himself by charging at the enemy.
Young Flash ran to the fallen Shadow Superwoman, realizing she had lost her life, and was overwhelmed with sadness.
Desperate, Young Flash asked the older Barry, "Barry, we can travel through time, just like you did to get here. What do I need to do?"
"If we want to go back, we have to run fast enough."
"Are you sure?" Without waiting for a response, Young Barry began running, accelerating continuously.
"Barry!" Old Flash called, accelerating to catch up, and together they reached the Bowl of Time.
"It's okay, we can solve this problem."
"I know what needs to be changed."
They exchanged a determined look, nodding, and accelerated together to reverse time, traveling back to the moment Batman was about to launch a missile.
Old Flash quickly warned Batman through his earpiece: "Bruce, don't launch the missile yet, they have a shield."
"Received." Batman removed his hand from the launch button, seeking other targets.
Unfortunately, this only allowed Batman to die a different way; the enemy was too strong.
Bravely, Batman piloted the Batwing, targeting formidable foes. When a giant wielding a massive iron axe caused destruction, Batman launched several missiles at him.
"Boom!!!"
From Batman's cockpit view, the giant emerged from the explosion's flames, landing on the Batwing, seemingly unaffected by the missiles.
The giant shattered the cockpit glass with a punch and reached for Batman. Batman pressed a button, spinning the Batwing's outermost ring at high speed. The giant, caught off guard, lost his grip momentarily.
However, the giant regained his hold and crawled closer to Batman. Despite Batman's efforts, the spinning Batwing couldn't shake him off.
Seeing the giant nearing the cockpit, Batman ejected, his suit spreading like wings as he glided to safety, hoping the crashing Batwing would damage the giant.
In the battle between Zod and Shadow Supergirl, Young Flash devised a plan to help: he'd use his super speed to run circles around Zod, blocking his vision.
"Whoosh!!"
Zod was surrounded by a blur, his vision obscured by the extremely fast-moving Flash.
Supergirl, initially startled, activated her super speed, flew into the circle, and delivered a powerful punch. Unprepared, Zod took the hit.
Supergirl continued to dart in and out, striking Zod repeatedly.
Eventually, Zod adapted, dodging an attack and countering, leaving Supergirl vulnerable due to insufficient time in the Sun.
This disrupted Young Flash's rhythm, causing him to fall heavily.
Zod's female adjutant, Faora, captured Supergirl, and Zod extracted the codex from her with a weapon.
In this world, Superman had never reached Earth. Zod had intercepted Superman en route, revealing to Supergirl that Superman hadn't survived and that the codex was within her.
Meanwhile, the giant, having survived the Batwing crash, emerged from the flames, unharmed.
