The team walked into the training room. To their surprise, other members of the league were there. Superman, Green Lantern, Flash, and GL had joined Batman, Black Canary, and Red Tornado in the room for today.

"Why do I have a sneaking suspicion that something is going to happen today," White says, barely audible.

"Cause you're a siren that can read people like books," Gar guessed, making most of them facepalm.

"Okay, too much time with Lena," White shook his head. "I need to program myself not to talk so much, again."

"Need any programming done, I'm your man," Cyborg cheerfully says. "Well, half man technically."

"Oh great," Dick complained. "Danny, you're turning Cyborg into you."

"And what's so wrong with that," Danny pouted, crossing his arms.

"I'm surrounded by nitwits," White covered his face with his hands.

"You get used to it, White," Kaldur tells him, patting his back. "It may take a while, but you do."

White smiled at him.

"At least not everyone is out of their mind," he said.

Looking between the two teens, swore she saw Aqualad blush at what Siren said. Her inner matchmaker and inner detective started working as one as she narrowed her eyes at them.

"You alright there, sis," Gar asked her.

"Oops, must have spaced for a second," M'gann said.

"What's with the number of extra visitors today, Bats," Bart asked, with his usual non-existent filter. "Are we getting a big mission? That be crash."

"No, nothing like that, Bart," Flash told his youngest protégée.

"The league just wanted to see how our two newest recruits do in battle," Batman told the team.

The teen heroes all looked at Phantom and Gold Siren. The twins narrowed their eyes at the Dark Knight.

"We've been here a year, we're not that new," Danny crossed his arms.

"If you want to get technical, Cyborg had joined the team after us," White reminded. "So he is technically the newest member of the team."

The league looked shocked at the two. The team, not so much. Normally, no one sticks up to Batman. His "dark" vibe makes even Superman weak in the knees. Yet these two hold their ground, their faces not showing even the slightest bit of fear or timidity. No one has ever been able to stand up to him like the way they did. Just so sarcastic and witty. They have no idea how.

"The league just wanted to see you train," Canary said. "You are still fairly new to this dimension and we need to see the full extent of your powers and training."

The twins shared a look that was an obvious saying of "of course that's what they want."

"In other words, you need to know if our 'kinds' are dangerous or not," Danny responded, quite harshly I might add. "You need to know our weaknesses in order to stop us, or any of our kinds, if it comes down to a certain situation."

The league and team looked at the two in shock. All of them, except Batman and Cyborg, were struck speechless. Cyborg, many times, has been the pair of ears that hear the two openly hate on people that treat them differently over their powers.

"Danny, White, it's not like that," M'gann tried. "They just..."

"Are completely paranoid and bias," White interrupted. "Don't lie or try to deny it. We've been heroes long enough to know that things like this always have a catch. I should know. In the words of an annoying imp called Rumpelstiltskin, 'all magic comes at a price.' We know how to read between the lines."

"As soon as we joined this team, we knew it was only a matter of time until this happened," Danny said. "Even if we don't like the reasons, we agree. Just remember that we aren't like the rest of your little 'sidekicks.' We didn't have mentors or anyone to show us the ropes. We learned through our own mistakes and fights. Not like we were able to train our powers after we got them."

"Why is that," Superman spoke first.

"People usually get the choice of fight or flight, no pun intended," White says, most of the team snickered because they knew he had wings. "We didn't get that choice. We had to learn right then and there, or we die. Simple. When we finally got the hang of our powers, we trained when we could. Besides that, we were always fighting for our lives or someone else's."

"None of you have powers, like ours," Danny says. "Ones controlled by our emotions. Even after a month of having them, we hardly had control. I kept phasing through the floor, or became invisible, or turned human again when I didn't want to. My brother would get nervous and whole buildings would shake. Don't try and act all high and mightily with us."

Between the seriousness of their tones, the aura of power they had, and the glares, the twins were a little... okay, a lot... more terrifying than usual. Considering that Batman was in the room, that says something about their glares. The Bat-glares from Batman, Nightwing, and Robin are terrifying enough. But now they have to add Ghost-glares and Siren-glares to their list.

"Let's just get this over with," Danny says, walking onto the platform. "Who's butt will I be kicking, this time."

Batman directed Robin and Nightwing onto the platform. Phantom changed to his ghost form and Siren into his siren form, both going up to the platform.

''I bet you a bag of chips that they're out in two minutes," Gar whispered to Impulse.

"A box of cookies says less than one minute," Bart countered.

"What are you two talking about," Flash asked the two youngest members of the team.

"How long it will take Danny and White to defeat them," Gar innocently said. "Nightwing, Aqualad, and Superboy are the only ones that give them even the smallest of challenges."

"Crash, isn't it," Bart laughed.

Robin pulled out his bow staff and Nightwing had his escrima sticks. Phantom formed his own staff from ghost ice and ecto-energy. Siren brushed off his wings, then held up his fists. Canary stepped up, their usual "referee" for sparring matches.

"This is a no powers allowed sparring match," she explained. "Phantom and Gold Siren against Nightwing and Robin."

"No powers," White says, looking at his wings. "Dang it."

He retracted his wings, causing them to vanish. The league stared at him, not knowing he could do that. They had been on the league with the Hawks for years and neither of them could do that.

"Way to ruin my fun," White said.

"Begin," Canary told them.

Robin wasted no time in charging at Phantom. The two clashed staffs, almost equally matched in their skill. Phantom twirled around his staff, blocking the jabs that Robin sent his way. Nightwing went at Siren. But Siren took his arm and the two spun around and were pushed away from one another. It took a second before Nightwing realized that one of his escrima sticks was missing.

"I thought I'd even the playing field, a little," White smirked, holding up the other weapon.

"Booyah," Cyborg cheered. "I love that kid. He just pick-pocketed Nightwing."

Siren tightly held the weapon. Nightwing had the other stick. The two swung the sticks at each other. When one would strike, the other would block. And vise versa. Both were quick with their movements. Phantom and Robin were pretty light in their feet as they spared. Robin back-flipped out of the way of a kick Phantom had sent his way. Phantom then jumped over a leg swipe Robin tried on him.

"You've gotten better, Rob," Danny said, the two's staffs locking as they pushed against each other.

"I, kind of, have to if I want to keep up with you and White," Tim smirked.

"Hey, at least Walker can't hold a candle to you," Danny snickered.

They pushed away from each other. Robin took a swing like the staff was a baseball bat. Phantom jumped up, out of the way. Then using his own staff to give him some more height, he landed on Robin's staff. It bent over like a tree with too much weight on the top.

"Sorry about this," he apologized.

"Oh crud," Tim swore.

Phantom jumped from the staff, causing it to shoot back up and nail Robin in the face. That had a few of the Team and League cringing.

While those two had been sparring, Siren and Nightwing were also locked. Only they had the escrima sticks against their arms as they fought. Shear strength may not be Siren's forte, but he knew how to position his body to give him added power even against stronger opponents. That little fact had definitely helped him against Solomon Grundy a few months ago.

Nightwing smirked.

"All's fair in love and sparring, Siren," Dick smirked.

Siren instantly got the message of what he was planning to do. Both of them pressed buttons on the escrima sticks they were holding. Both of the sticks lit up with electricity. But with them connected, they ended up causing a backlash to them both. They were both zapped. But Siren recovered faster, taking advantage of Nightwing's daze. He elbowed him in the back, sending him to the ground.

Both Bat-Brothers were down. The league was left speechless. Looking at his watch, Beast Boy smirked toward Impulse.

"I win," he stated, Impulse mumbling.

"Did...did those two just beat Nightwing and Robin," GL gawked at the two.

"In record time, according to my data," Red Tornado responded in his robot tone.

That definitely got the other league members staring at the ghost and siren boys. That meant that they've beaten them more than once. And that's not an easy thing to do, as they were trained by thee Batman.

"That, my friends, is how skilled you get when fighting for your life without ever having a mentor to train you," Danny quipped. "Do not try that at home."

As per usual, that caused Siren to facepalm. Phantom made his icy staff vanish. He didn't use his ice core very often, only really using it when he needed to. Like when the Team had to fight Firefly, Heat Wave, Deathstorm, or Volcana. He preferred his ecto attacks for reasons no one really knew.

"That... was impressive," Green Lantern admitted.

"Boys definitely got some skills," Flash agreed.

Batman stepped forward, wanting to start the next sparring match.

"Aqualad, Super..." Batman started.

"Actually, I'd like to give it a shot," interrupted one of the visiting league members.

To everyone's surprise, Superman was the one that had stepped up. An even bigger shock was the looked of "this might be fun" in both of the twin's faces.

"Superman, have you lost it," Flash asked, shocked and zipping next to the hero. "These two aren't Darkside or Mongol. They're kids."

"Well, one of these 'kids' is technically already dead," Danny deadpanned. "What more can he do to me?"

Siren slapped his brother on the back of his head.

"While most of your antics have me wanting to keep a headstone in my closet just in case, this might actually take the cake for crazy," White told him. "And yet, I'm still oddly intrigued by this fight."

The Team just stood there, completely gobsmacked. Nobody would have ever thought that two teenage boys would actually want to fight Superman. Everyone turned to the All-American hero.

''What,'' he asked. ''I just want to see how much they can take.''

''You just want to fight them because you've heard how strong they are,'' Flash said.

''I just want to see how they fare against a member of the league,'' Superman stated in a 'matter of fact' type of way.

Flash just rolled his eyes at that statement.

''You two sure about this,'' Kaldur asked the twins.

''You'd be surprised what we can handle,'' Danny says.

They went back up to the platform. Superman soon joined them. Siren brought out his wings and Phantom floated up a little.

''Match... begin,'' Canary called, slashing her hand down like signaling a car race.

Superman went right at them, flying at his high speed. What he didn't count on was that Siren's scream packed more of a punch than Canary's. The gold waves from Siren blasted him right to the ground.

''I'm no banshee, but I do know how to scream,'' White smirked.

Phantom shot out a few ecto blasts. One of them got Superman in the shoulder. There was a slight release of green steam from the impact. Superman barely flinched.

''Okay, looks like I need to get some new tricks,'' Danny said.

Superman then got his groove back. He got up and flew right at them. Siren flew up and out of the way while Phantom tried his hand at seeing if his super strength matched that of the Kryptonians. Turns out, it was an almost match. Heavy on the almost. Superman pushed back Phantom, who dug the toes of his shoes into the ground to get some leverage. Now, this was a fight that got the ghost boy to sweat.

''I've fought ghosts ten times my size, this is nothing but a workout,'' Danny still to be his witty self.

Superman eyed Siren coming in. He tightened his grip on Phantom's fists and spun around with him. He threw Phantom right into his flying twin. Both of them were sent crashing to the ground. Phantom quickly stood back up, his eyes glowing. He shot his green ecto eye rays. Superman countered with his heat vision. The beams made contact, creating a bright light where they met. But Siren's hero name doesn't start with Gold for nothing. He flew up, collecting the vibration energy around him. It formed a ball of the energy in each of his hands.

Siren faced the adult hero. He took the vibration energy and clapped them together. It created a kind-of supersonic boom. Gold waves boomed right into the Kryptonian. He crashed into the wall, creating a big spider web crack.

"Just because I'm the siren of pure heart, doesn't mean I can't kick your butt from here to the Isle of Angels," White smirked.

The twins high-fived each other. They approached the hero. But Superman quickly got on one knee and clapped his hands together with his super strength. It caused a burst of wind and force that threw both twins backward.

"Should have known that was too easy," White groaned.

"Yeah, you're good but not that good," Danny agreed.

Superman flew above them and took a deep breath. He breathed his ice breath at the two. Quickly, the power caused frost, and then ice, to form on and around them. In a matter of seconds, the twins were now a ghost-cicle and siren-cicle. They were trapped in ice. But to the surprise of the league, it didn't last long. Phantom's hands lit up with his ecto energy. Siren's eyes glowed gold. A second later, the ice was shattered by Phantom's blasts and Siren's screams.

Green Lantern went over to Batman as the fight continued.

"So, have you discovered anything that could weaken either of their kinds," he asked the caped crusader.

"I have been researching for over a year," Batman told the Lantern. "Not even Fate knows anything about how to weaken them. He hasn't met either ghosts or mystics before."

"So much for him being Earth's 'Sorcerer Supreme' then," Green Lantern said. "They can't have no weaknesses. Even Superman is weak to kryptonite."

"I suspect the two know what is strong against their kinds," Batman says, looking at the sparring twin heroes. "They just haven't told us."

"Why would they do that," Green Lantern asked.

"I have heard about a lot of things the twins have done on missions," Batman explained. "They value the Team, that's without a doubt, but each other are the ones that they protect the most. After what happened on their own world, it does not surprise me that they'd want to keep what is harmful to the other a secret. They most likely have come across them before and don't want the other hurt."

"That is noble of them," Green Lantern said. "Family is obviously important to them, and they are the only family they have left."

Superman was showing that he wasn't one of the strongest members of the league for nothing. He was highly resistant to Phantom's ecto blasts and while Siren could definitely handle himself in a fight, hand to hand combat was his weakest point. Since Phantom didn't have his ecto rays until his first fight with Desiree, he had more hand to hand experience.

Phantom made his hands glow with ecto energy, like energy gauntlets. He traded blows with Superman, looking like a Rocky movie. As they went at it, Siren landed near them. Opening his mouth, he let out his siren shriek. It was his power that causes those around him pain and confusion. It also makes glass shatter and machines go haywire. It sounds like a thousand bats shrieking combined with the screaming of a pterodactyl. His shriek did not seem to go with Superman's super hearing. He held his ears, yelling.

Phantom used the advantage and took the bull by the horns. He used his strength to toss Superman across the room. He collected two of his ecto blasts in his hands, combining them. A stronger, and bigger, blast came out. Superman held up his arms, the blast forcing him to slid backward. But he soon started to fly forward, punching his way through the beam. When he made it to Phantom, he was hit right to the ground. He then used his arctic breath to knock down Siren when he went in for a blow. He then started flying around the twins. The faster he flew, the more wind picked up. He created his own mini twister. Both twins were swept up in the twister, flying out of control.

"Now I know how Dorothy felt," Danny yelled.

"Shut up, Danny," White yelled back.

The twister soon ended as Superman came to a stop. The twins fell to the ground, weakened by the extensive match. Superman landed near them.

"Those two are done for," GL commented to Flash. "They'll never beat him. They just need to face the inevitable."

The twin's heads shot up. Their eyes both flashing.

"Me, my future, I'm inevitable. I'm still here. I still exist. That means you still turn into me."

"You have fallen to him once, and you will fall to him again ."

The two of them stood up, the entire mountain starting to shake. Something inside them had just snapped.

Cyborg's arm started beeping. He opened up his arm computer. His system was detecting high energy levels. And he knew exactly where the energy was coming from.

"Not good," Cyborg stated.

"I will never become you," Danny boomed, using his ghost voice. "My future is mine to decide."

Before anyone else could move, Phantom's glowing hands slammed down. His ecto-energy caused fire-like power to shoot up in a straight line. Like when lava explodes from the ground during an eruption. It crashed into Superman, sending him right into the wall. Phantom and Siren looked down right pissed.

Batman narrowed his eyes and turned to Canary. All she did was cover her mouth in surprise and then turned to Aqualad. Aqualad had been looking on with wide eyes but saw Black Canary and the question implied.

"They...they must be re-living the past. I don't think they're with us right now. We need to snap them out of it," the Atlantean told her.

Canary turned back to Batman and was about to agree with Aqualad, but the Caped Crusader only held up his hand.

"Hold on," he told her. "Let's see what they do..."

Nightwing turned to Batman, completely shocked.

"What," he exclaimed. "Have you lost it. We need to stop them. Before they end up hurting Superman. Along with themselves."

Batman simply glared at his first protégé.

"That's an order," he said coldly.

Superboy glared at the bat but just huffed and stomped over to Miss Martian, who looked as though she was about to have a heart attack.

Back at the scene, Superman was internally confused after that last shot, but he wasn't about to back down. He got into a fighting stance.

"Give me your best shot, kid," he said.

Phantom growled and planted his feet to the ground. He remained in place as he shot a white/green energy beam at the Man of Steel. The latter put up his arms to shield himself. but they were stronger than his normal ecto-blasts. It hurt more than the previous ones. But he got back up when the blasts stopped and fired his heat vision back toward Phantom. The eye beams seemed to hit an invisible shield as they suddenly were torn apart and the beams circled around him before they were dispersed by a wave of Siren's hand.

Superman's eyes widened and he stepped back, completely unaware that they had that kind of power.

Siren narrowed his fully gold eyes.

"Time to end your games, Dan," he boomed in his siren voice. "Your reign ended the moment we got here. You have no power over us."

Phantom took a deep breath and Canary's eyes widened in fear as both she and Batman realized what was going to happen. Especially when Siren collected his gold energy into his hands again.

In sync, the two adult heroes yelled "COVER YOUR EARS!"

Everyone quickly covered their ears. Just in time too, for what happened next. No one but Black Canary and Batman expected it.

Phantom let out an ear-splitting scream. More powerful than Siren's scream or Black Canary's canary cry. It sounded as though thousands of souls were being tortured all at once, screaming for the pain to end. The wail was so powerful that it came out in green sound waves. Siren combined it with his vibration waves, almost doubling the already strong power. The combo was too powerful for even Superman's endurance and he was flung backward into the wall, creating a large webbed crater. He stuck in the crater as the waves kept coming. They could feel how the entire room mountain shook from the power of the twins. Between the both of them, some were even afraid that they'd bring Mount Justice down onto their heads. Eventually, the scream stopped and the room stopped shaking. Superman fell to the ground, groaning but not getting up. Phantom was trying to regain his breath and looked completely exhausted and on the verge of collapsing.

Everyone let go of their ears and now stared at the teen heroes in utter shock. Though Batman had a look of disappointment and anger displayed on his face.

Phantom and Siren looked up at Superman and then back at the Team. Their eyes went back to normal.

"Ah Hades," Siren swore in his head.

"Great," he thought. "Now I have to explain why I kept that power a secret. Well, at least Batman and Canary already knew."

That's when his advanced hearing picked up a cracking noise. He turned and saw the ceiling above the weakened Man of Steel beginning to crack and break. And Superman was only just now beginning to stand up. Phantom quickly dashed over to him and shoved him out of the way, just as the rubble began to fall. Siren dashed forward. Superman was in shock and confused as he stared at the now covered Siren and Phantom. The rubble had fallen on top of them while their backs were up, and now they couldn't see the two. What scared him the most was that there was no sign of movement.
