This is an attempt to work with an Owlman and Nightwing dynamic. I've wanted to try it so here's some practice. this does combined Crisis on Two Earths and the Forever Evil arc. This story mostly follows the Crisis on Two Earths movie, but with one or two elements from Forever Evil (mostly around Dick and his Earth 3 counterpart). Also, everyone will be using their Superhero name for most, if not all of the story.

It wasn't often that Nightwing made the effort to visit the Watch Tower, but after Batman called him up to possible help with some needed adjustments, he couldn't say no. When he wasn't assisting Batman with the technologic side of things, he was curiously dotting around Superman's work, willing to help if requested. He was prohibited from exiting the Watch Tower on account of his body's need for oxygen and the current lack of a proper spacesuit.

Nightwing would watch on as Superman, Wonder Woman, and a one or two other space savvy heroes worked on the exterior. It wasn't all that interesting to him, but it did give Nightwing something to keep him preoccupied before his next project.

It wouldn't be long before they all came back, Superman having received a call about some trouble in Metropolis. After explaining the situation, he would take Wonder Woman and Flash along with him. He caught them taking a craft down to Earth, which he wished he could be on so that he could see what was going on.

"Nightwing!" Batman called.

His attention bounced in Batman's direction. Seeing that Batman needed his help, he trotted over to him. The founding members would start to gather, wanting to hear the man out, before taking the appropriate action.

The trio returned with, of all people, Lex Luthor. Supposedly, he was from a parallel Earth and was in need of help.

Nightwing was already in the meeting room, having been asked to clean it up. Upon making his way for the exit, he was bombarded by the founding members. Backing in a few steps, he allowed them and their guest enter. He didn't move as everyone got situation, hoping that he could catch the meeting.

"Nightwing!" Batman notified.

"What?" Nightwing playfully replied.

"This is a League matter. Can you find something to keep yourself busy, not in the meeting room?"

"Yeah. I saw Shazam earlier and we wanted to catch up."

Dick awkwardly excused himself from the room. The door would stay open for a few seconds before automatically. All eyes stayed on the door, Lex seeming to have a bit of an interested in the now vanished youth.

"Some people don't change." Lex curiously noted. "How peculiar."

"Hey!" Superman interrupted, not liking his unusual attentiveness. "Don't get any ideas."

An understanding smirk emerged, understanding why Superman intervened. He would begin to make his way towards the window, catching a glare from Batman.

"My apologies. Where I come from, it's a little surprising to see such a familiar occurrence."

Lex began to explain his story. How he came to this Earth looking for help to deal with the Crime Syndicate, an evil version of this world's superheroes. How no one wanted stand up to these criminals. He went on to explain how he was the last person of his Justice League, and as such, needed their help taking them down.

After explaining his story and why he was there, Martian Manhunter would lead him into the room that they had entered. With the second door already closed, he requested that Lex stay there as they discussed it, closing it soon after.

The founding members would discuss what they should do next. Superman's suspicions were the first thing to be mentioned, but after a counter argument from Wonder Woman, they would move onto how they should help. The only person to disagree was Batman, feeling like they weren't ready to help another Earth until they were fully prepared to protect them. The other members ended up disagreeing with him and decided to go ahead to help Lex anyways, leaving Batman behind.

As they got Lex, they let him know that they'd help. As they opened the other door, they ended up face to face with Nightwing, who was waiting on the other side. He jumped back startled, not expecting to see them. There was an array of surprise and annoyance on everyone's face as Nighting took a step back, embarrassed that he had gotten caught.

"I thought you said you were catching up with Shazam." Superman reminded, folding his arms.

"I was," Nightwing blurted out, "but as it turns out, he had to attend to some academic business back home."

"And why are you here?"

Nightwing shuffled around a little bit. Nerviousness was apparent and he was trying to find what he wanted to say.

"I just want to go with you guys, okay?"

"Why?"

"I want to get out. Stretch my legs out. You guys are going to a parallel Earth and I want to come."

"Do you honestly think Batman would approve?"

"Of course not, but you're not him. Besides, he's keeping me on desk duty and you know how much I hate being stationary."

The other members and Lex watched as the two went silent. They didn't entirely want to get involved with the request, opting to wait it out. Since the only other person the younger vigilante looked up to was Superman, it was probably for the best that he handle it. Not to mention Nightwing's mentor was a door away.

After a few moments, Superman began to contemplate the request. The request itself seemed typical enough, but the context was a little risky. The moment the others noticed an affirmative response, someone knew they had to step in.

"Superman, no." Wonder Woman intervened. "You and I both know exactly what he would say about this."

"You have a point." Superman admitted. "He would throw a fit if we involved his protégé behind his back."

"I don't mind." Lex added. "We could use a Gothamite since Batman isn't coming. Plus, we could use an extra hand."

A pleased grin graced Nightwing's face, loving that he had someone's support. Even if it was Lex Luthor's. Superman, on the other hand, wasn't too fond if the man's comment, feeling that it wasn't needed and only made the decision harder.

"Please." Nightwing begged. "Just this once."

Nightwing continued to stare the Kryptonian down, a begging face continuing to stick around. It was starting to get a little unsettling.

"Oh alright." Superman finally agreed. "You can come, but you better stay out of trouble. Batman would have my head if anything happened to you."

Superman started to lead the newly grown team to where they needed to go. Nightwing was gladly trotting along.

"Me? In trouble? As if." Nightwing scoffed. "Do you know who you're talking to?"

"That's what worries me. That's why I'm warning you."

Let me know what you think. I know this may not be perfect, but it's a start.
