Y/N saw the heroes all around the Watchtower, he sensed so many strong power levels from them. Though it is new to him to see a lot of costumed heroes, he hasn't really seen superheroes before until he met Superman. But the power he senses from Superman was suppressed like he was holding back his true power. Many of the heroes we're holding back their true power, this was something that made him a little excited. The other heroes were worried about Hal seeing him injured but knew Superman was taking him to get medical help.

Y/N: "You want me to join your team?"

Superman: "Yes, after all, you've proven that you have what it takes to be a member of the league. I want to help you control your true potential, after all, I know you haven't reached it. Now I want to know what will your answer be, you don't have to join if you don't want to."

Y/N: "Actually, I do want to join the Justice League. After all, you're definitely stronger than me, so I want you to train me. I'm still pretty weak, I need your help to get stronger."

Superman: "It doesn't matter how strong you are. What matters is what you do with your power that counts, will you use it for personal gain? To help others? Or never use it at all? That is a question you should ask yourself."

Y/N: "That's a question I know, I want to protect people. But the responsibility I've gained is a big one, one that will risk all of existence. I'm still weak... I need to get stronger, that is why I want you to train me Kal-El!"

Superman: "Let's get Hal some medical attention, we'll talk about training there."

Both Superman and Y/N walk down the halls of the Watchtower, he noticed some heroes looking at him weirdly. Some of them seeing the tail he has, while others comment on why he wasn't wearing some costume to protect his identity. Both of them make it to the medical room, Kal-El lays Hal on the hospital bed where Superman hooked him up to the various machines.

Superman: "So training, Y/N, now I've learned martial arts from various teachers."

Y/N: "I want you to teach me what you know Superman, I want to get stronger with your help."

Superman: "I'll teach you what I know, but tell me what you sensed before. You said it was dark energy, what is coming this way Y/N?"

Y/N: "Something very dangerous, this is even stronger than the last time I've encountered this dark energy. This has the power to destroy the entire galaxy, maybe even the universe."

Episode 11: The Justice League

_____________________________________

While the two were talking, a certain detective was teleported up to the Watchtower. The Batman was making his way to the medical room, he heard about the Green Lantern from another hero who told him about it. Once Batman walked into the room, he still had a scowl on his face and he knew that Superman knew something about this.

Batman: "Superman, what happened here?"

Superman: "Something powerful knocked Hal straight to Earth, this being was strong enough to knock him unconscious. It was some being that had some dark energy, I was helping Y/N here to control his powers. That's when we both heard him falling to the ground like something punched him to Earth, but Y/N here said he sensed a powerful energy that could threaten the entire universe. Maybe even all of reality."

Batman: "Something out there knocked Hal out, but are you sure you can trust him?"

Superman: "Yes, he has shown me that his intentions aren't evil, which is why I asked him to join the Justice League. He is part Kryptonian but he isn't from this universe, his universe is gone which makes him the last of his kind from that universe. What he has said so far has added up, he is telling the truth about the darkness that is invading the multiverse."

Batman: "Clark! We have witnessed friends become enemies, just because you trust him doesn't mean that he is guaranteed to help mankind!"

Superman: "Bruce, I know that you've dealt with a lot of betrayals, but you want to know something. Not everyone is out to get you."

Batman: "If you turn out to be wrong Clark, don't expect me to come to your aid. You can't trust everyone just because they even show any good intentions."

Y/N wanted to say something to break up the conflict but he didn't know what to say, by the way, he can tell how they interact, the two are friends.

Superman: "You know something, Bruce, you're not always right."

The complete silence after those two exchanged arguments, but Y/N was wondering why Superman was defending him. Batman just glared at Superman then he walks to the door, but before he left the room he stopped midway through the door.

Batman: "We'll finish this discussion later Clark, right now I'm gonna find out what caused those energy readings. Also Y/N, I got my eyes on you."

Batman walked out of the doorway and left the medical center, Superman just threw aside his anger as he had to think rational for now.

Superman: "Batman is right, we should find out what those energy readings are from."

Y/N: "Clark? Why'd you defend me for, I could've just told him I wasn't a threat?"

Superman: "Batman is not the easiest person to convince, but I've defended you because I know that you are a good-hearted person. But I have to agree with Batman, but you shouldn't judge someone by first glance. I believe that you could be a good hero, everyone can be. But I can't always help you out, I have to help out those who can't help themselves."

Y/N: "I understand his reasoning for not trusting me Clark, honestly I can't blame him for being paranoid about some stranger."

Superman: "I know, after what he has been through, it is understandable."

Both of them hear Hal slowly waking up, knowing that he is injured Y/N opens the bag that tied to the waistline of his pants. He pulled out a senzu bean, he then walks over to the injured Green Lantern and hands him the senzu bean.

Green Lantern: "Who are you? What are you giving me?"

Y/N: "This is a senzu bean, it restores your stamina and heals your wounds. Eat this and you'll feel better after all you have a broken arm."

Green Lantern: "Senzu bean huh? That sounds very weird but considering all I've seen, weird is something that happens daily."

Hal takes the bean and he slowly puts the bean in his mouth and he began eating it. Once he swallowed the senzu bean he felt like all of his injuries were gone, he felt like his entire body was healed up and his stamina restored. He got out of the hospital bed and moved his arm up and down, he felt the muscles were perfectly fine.

Green Lantern: "Wow! That bean actually worked, I don't know who you are but you're a miracle worker."

Y/N: "Yeah, these senzu beans are really useful. My name is F/N L/N, I'm a Saiyan and Kryptonian hybrid from a different universe."

Green Lantern: "An alternate universe? That does sound too weird now, but thank you for healing me. But I've got to tell the Guardians of what's coming, this crisis is big!"

Hal's whole body was surrounded by a green glow, he then flies out of the room in a hurry. The whole entire Watchtower starts to shake violently, some heroes were struggling to keep standing, while other heroes are able to keep their balance. Superman's eyes widen as he heard a sound that he dreaded of hearing.

Superman: "No..."

Superman rushes out of the room with incredible speed, he looked like a blue and red streak. Y/N heard a loud boom, he then sensed that same dark energy that causes his eyes to widen and his pupils got smaller. He then hears a roar, so Y/N runs out of the room at supersonic speed. He then looks out the window to see what this universe calls a boom tube.

Then he sees a creature coming through the boom tube, it was roaring and this was a monster that had incredible power. The monster was making it's way to the Watchtower windows, once it reached the Watchtower windows it crashed right through them. This causes the air to be sucked out into space, Y/N was able to stay in the same spot despite the air being sucked out into outer space. But then the emergency shutters close off all the windows and a red emergency light illuminates the whole room.

Y/N looks at the monster that came crashing in and it looks right at him roaring, this causes Y/N to get in a fighting stance as the monster charged right at him. Y/N flies right at the monster as both of them were about to clash.

Y/N: "HAAAAAAAAAAAAAAAAUUUUUUUUUUUUUUUUUUGGGGGGGGGGGGGHHHHHHHHHH!!!"

To Be Continued...

_____________________________________

Now things are getting intense again, I will be close to finishing this arc soon but it will be a few more chapters than the Dragon Ball one because of how this arc will be. So what do you think of this arc so far? Sorry that this chapter looks a bit rush but I need a little more inspiration to get back into my creative flow. Other heroes will be in this arc so don't worry, just not every hero will be here because that is too many characters to keep track of. That is all I have to say, so have a good day and hope you've enjoyed this chapter.
