Guest 2.0: I'm probably not going to do that, it would just screw up the passing too much. Sorry.

Guest: So did I, it was the best version of Anatoly. That was the intention.

Earth-38, the DEO

Night

Things were beginning to get strange. The entire city was shaking as, at the DEO, alarms blared and agents ran around, none of them really sure what was happening.

"Brainy, what's going on?" Alex Danvers asked her technician.

"National City is under attack, by nature. Hurricanes, tornados, and an earthquake is striking the entire city. Strangely, there does not seem to be any reason for it," Brainy explained.

"Because this isn't nature."

The pair whirled around, seeing Supergirl standing behind them. She looked like she had been to Hell and back, her hair was a mess, her suit was torn in a few places on her legs and arms, and she was covered in dirt and grim.

"Kara, what happened?" Alex immediately asked in concern.

"I went out there to try and help stop this. I fought…something. It looked like tornados and hurricanes, but it wasn't. It know it sounds crazy," Kara explained.

"Try unthinkable, infeasible, impossible," Brainy listed. But the only explanation is-"

"We have a major Crisis on our hands," J'onn said as he appeared behind them in his human disguise.

"What ae you talking about?" Alex asked.

"The Monitor," J'onn said.

"I thought he was a Flash and Green Arrow problem?" Brainy asked confused.

"He's of every earth. Last year he tested Kara and the Earth-1 heroes, this year he's been testing me, to make sure we're all ready for what's coming," J'onn explained.

"What exactly is coming?" Alex asked uneasily.

"I do not know. But it scares The Monitor enough that he has tested heroes from across the multiverse. It can't be good," J'onn said grimly.

Earth-1, Ohio

Same time

Barry whirled his dagger, stabbing a Hellhound with it in the side. It cried out as it disintegrated into dust. A few feet away, Patty stabbed a second Hellhound with her dagger, which tuned to dust as well.

"That's the last of them," Patty said once they had finished.

"This time," Barry said uneasily. "I don't think it's a coincidence that all these monsters came out of the woodwork."

"You think it's the Crisis," Patty realized and Barry nodded grimly.

"It has to be. I can feel it," Barry said grimly.

Before another word could be spoken, the pair were covered by a bright light. When it vanished, there was only an empty street, no sign of them.

Earth-2, Central City

Same time

Things were not looking any better for Earth-2 than they were for Earth-38. They were also being attacked by an enemy they could not see. At Star Labs, Harry Wells was readying his Pulse Rifle as his daughter, Jesse, watched him uneasily.

"Dad, you don't have to do this," she said.

"I may not be as smart as I once was, but I can still work this. We need all hands on deck Jesse," Harry pointed out.

Before Jesse could argue, there was a bright flash of light. When it faded, Harry was gone, to her shock.

"Dad? Dad?!" Jesse cried out as she looked around wildly, finding no sign of Harry.

Earth-1, Tibet

Same time

Thalia fired arrow after arrow alongside her hunters, taking out various monsters. Once they were all clear, they took a breath.

"What is going on? It's like every monster in the world came out tonight?" One of the Hunters asked.

"I don't know," Thalia said as she turned to face the other Hunters. "But we have a job to do. We can't let the world be overrun with these things. We stand our ground and we fight."

Suddenly, there was a bright flash of light. When it vanished, the Hunters were shocked to see that Thalia was gone.

Argo City

Same time

Clark Kent was watching with a soft smile as his wife rocked their son to sleep. He felt content for the first time in his life. Suddenly, there was a bright flash of light. Lois started and, as it faded, realized Clark was gone.

Earth-38, the DEO

Same time

Kara, Alex, Brainy and J'onn started as there was a flash of light and a blond haired man in a green suit materialized.

"On your knees, now!" Alex barked as she pulled out a pistol, all agents in the room taking aim at the man.

"That won't be necessary," he said calmly.

"Who are you?" J'onn demanded, unnerved by the fact he couldn't read the man's thoughts.

"In another life, I was known as Luke Castellan. Now I am simply Pariah. I am here to help, I was sent by The Monitor," Luke said, which got their attention. "I know what's happening and I know what needs to be done."

There was another flash of light and, when it added, Oliver, Barry, Percy, Annabeth, Clark, Patty, Harry and Thalia stood behind Luke. Oliver, Barry, and Clark were in their suits while Percy, Annabeth and Patty were in their armor. Thalia and Harry were dressed as they been moments earlier.

"And now that we're all here, we can get started," Luke said and Thalia stared.

"Luke?"

"Hey Thalia," he said as he turned around to face her, a remorseful look on his face. "Despite everything, it's good to see you."

"You died," she said bluntly and he nodded.

"I did. It's a long story, but it's not important. The multiverse is in danger, Kronos is back," Luke said.

"So how do we know you're not working with him? You helped him rise the last time," Thalia sneered.

"Thalia, as hard as it is to believe, we're on the same side here," Percy tried to reason with he.

"It's okay Percy," Luke said as he walked over to her. "I deserve your hatred for what I've done Thalia. I know you don't trust me. I just want to make things right now. I swear on the River Styx."

Thalia stared at him for a long moment before nodding.

"Okay. So, what's going on?" Thalia asked.

"I'm a little confused myself," Clark said, wondering what on earth was going on.

"Patty?" Annabeth said as she noticed her sister.

"Hey Annabeth," Patty said as she waved awkwardly.

"Harry," Barry said in surprise as he saw the Wells.

"Allen. You have an idea what's going on?" Harry asked.

"I'll explain everything if we can find a place to talk privately," Luke promised.

Later, everyone sat in the conference room as those not in the know were brought up to speed.

"So, the Greek gods, Zeus, Athena, Poseidon-" Alex started.

"All real," Luke said with a nod.

"And you guys are demigods?" Kara asked as she looked around at Oliver, Barry, Thalia, Percy Annabeth and Patty.

"I had a hard believing it to, but it's true," Oliver said with a sigh.

"And this Kronos is the one behind what's happening?" J'onn asked curiously.

"When I stabbed myself to stop him, I destroyed his physical body. It would take decades for him to reform, centuries for him to regain all his power. He thinks he's found another way," Luke explained as they all turned to him. "Each Earth has an Olympus. By destroying it and consuming the energy of its power source, Kronos thinks that he can regain his physical body."

"Which is why he has monsters attacking the other earths, so he has the gods distracted," Patty realized and Luke nodded.

"I was there when he attacked Earth-1's Olympus three years ago. He's gonna need to find some way to enter it," Percy pointed out.

"Kronos has more than monsters helping him. He has a demigod working with him, I don't know who," Luke explained.

"Okay, let's focus on what we do know. Where is the entrance to Olympus?" Oliver asked.

"I'm gonna assume it's not in the Empire State Building on this earth," Percy noted.

"No. On this Earth, the entrance is hidden in Cat Co World Wide Media," Luke said and Kara looked surprised.

"Somehow, that's not a surprise," Clark muttered.

"Okay, so we protect it," Oliver said with conviction.

"There's more to worry about," Luke said and they gave him an odd look. "Oliver, the Monitor has had you, Percy and Annabeth on a quest, picking up items in order to pull off the final phase of his plan to stop Kronos. There's one more item needed and it's on this earth."

"Great, more risking our lives," Percy said sarcastically.

"What is it?" Oliver asked.

"A Dwarf Star Particle. Not like the one your friend Ray Palmer uses, this one was developed by Lena Luthor and is kept under lock and key in L-Corp," Luke explained.

"Yeah, that's gonna b a problem," Alex said as she, Kara, J'onn and Brainy tensed.

"Why? I thought Lena was your friend," Clark said confused.

"Lex told Lena my secret," Kara said after a moment. "He twisted it in the worst way possible and now Lena hates me. She's not just gonna hand it over to us."

"Then we get it the old fashion way: we steal it," Oliver said.

"So, who wants to save the world?" Percy asked as he leaned back in his chair.

I know not a whole lot happened this chapter outside the heroes of the Arrowverse and Percy Jackson universe coming together, but next chapter will have a lot of developments.
