The Renewed Justice League sat around a large conference table with various other superheroes from different Earths. "We need to talk about the transportation system in the multiverse," said John Cena. "It's a mess on some Earths, and we need to work together to fix it."

Sylvia Pankhurst nodded in agreement. "We propose building a multiversal metro system that would be free to use, clean and safe."

Tom Higgenson added, "This system would not only benefit the environment, but also help improve the quality of life for citizens across the multiverse."

One of the other superheroes spoke up, "But why should we spend our resources building something like that? It's not like it's necessary."

Delilah DeCrescenzco countered, "It is necessary. Look at the Highway Horde's Earth, it's polluted and uninhabitable. A metro system could have prevented that. And on our Earth, we had to fight against the destructive impact of car culture."

Jordan Peterson chimed in, "The metro system is not only environmentally friendly, but it also promotes unity and social cohesion by bringing people together from different areas."

The superheroes discussed the benefits and drawbacks of building a multiversal metro system for hours. Finally, they came to a compromise. They would build a metro system, but it would not be mandatory for all Earths to participate. The superheroes would work together to fund and build the system, and any Earths that chose to participate would receive the benefits of the metro system.

Months passed, and finally, the Multiversal Metro was complete. The superheroes and citizens of the multiverse could now travel between Earths easily and without pollution. It was a symbol of unity and cooperation among the many different worlds of the multiverse.

Post-credits

Magneto and Joker stood outside the abandoned building, waiting for the mysterious meeting to begin. Magneto's cape flapped in the wind, and Joker fiddled with his purple bowtie.

"You know, I've always appreciated a good shade of purple," Magneto said, looking at Joker's suit. "It's the color of royalty, you know."

Joker chuckled. "That's why I wear it. Makes me feel important."

Magneto nodded. "It's important to project an image of power, even if it's just an illusion. People will believe what you want them to believe if you look the part."

Joker grinned. "You sound like a fellow who knows what he's talking about. I like that."

Magneto smiled back. "I have spent many years perfecting my image and honing my powers. It takes a certain kind of person to succeed in this world."

Joker nodded in agreement. "That's why I like you, Magneto. You understand how the world works. You're not afraid to take what you want."

Magneto raised an eyebrow. "And what is it that you want, Joker?"

Joker shrugged. "Oh, you know. Money, power, chaos. The usual."

Magneto nodded. "I can respect that. But sometimes, you have to play the long game. Build something that will last beyond your lifetime."

Joker snorted. "Sounds boring to me. But I see your point. If you're going to do something, do it right."

Magneto smirked. "Exactly. And that's why we're here today. To do something big. Something that will change the course of history."

Joker's eyes lit up. "Ooh, I like the sound of that. What are we waiting for?"

Magneto grinned. "The others should be arriving soon. Then we can get started."

Prompts: #1

Tell a story where the Renewed Justice League work to convince the heroes and leaders of other Earths to build a decent, free metro system throughout the multiverse, but not all the other Earths are convinced. The Renewed Justice League cite the Highway Horde's polluted Earth and their own Earth as examples why public transport is good. In the end, after much negotiation, the Multiversal Metro is built. Dialogue and exposition. #2 Tell the story of Magneto and Joker bonding over a shared love of purple, whilst waiting outside a building for a mysterious meeting. Do not reveal what the meeting is. Dialogue and exposition.
Notes: Again, the Multiversal Metro was originally ChatGPT's idea, but I think it got expanded on much better here. Originally, it was a weird resolution to the multiversal adventure of the previous issue. Plus, I can now tease future plotlines a bit better!
