The team watched as the Justice League went up against a large space ship, it took them all out within a few minutes. When all of the Leaguers fighting were gone Red Tornado got a call from Zatara, "Tornado, did you..."

Red Tornado spoke, "Yes Zatara, we saw, celestial defenses have failed, initiate all terrestrial measures."

"Affirmative, see you in the field."

Tornado turned to the heroes, "I must join the League, we will protect the planet at all costs, but should we fail, the responsibility falls to you."

Aqualad looked at all of them before speaking, "We stand ready."

After Red Tornado left Robin pulled up news reports from other parts of the world to see what was going on. One by one they watched as the Leaguers were killed, several different cities were being attacked and all of the heroes were eventually killed. After a while Red Tornado contacted them, "Red Tornado to cave, I fear I am all that remains of the League."

Robin responded, "RT."

When he didn't answer they knew he must have been killed too, that meant that they were the only ones left to stop the aliens. Aqualad spoke, "We are Earth's heroes now."

Superboy looked at him, "So what are we waiting for, a theme song?"

Aqualad looked at him, "A strategy, Earth's weapons are ineffective, and it has been made tragically clear a direct attack will not succeed."

Robin used his holo-glove, "Checking satellite imagery." He pulled up a holographic image of the world and it had red spots on it, "Here's where the aliens are now."

Superboy pointed to one, "This one get lost?"

Robin spoke, "That's Superman's fortress of solitude.

Superboy looked shocked and confused, "Superman has a fortress of solitude?"

Robin spoke, "It's power source must have attracted the aliens attention, at least enough to send a scout ship to investigate."

Superboy looked away, "Must be some fortress." Danny mentally sighed and he realized that his head hurt a little, he felt very apprehensive toward this whole thing.

Aqualad spoke, "We will target this lone ship."

Kid Flash spoke, "Yeah, break it down, build more, hit those ugly aliens with their own mojo."

Artemis elbowed him in the side, "Martian and Kryptonian in the house."

Kid Flash laughed nervously, "Not that all aliens are automatically ugly."

Danny shook his head and they headed to the bio-ship so they could go to Superman's fortress. Most of them dressed in warmer clothing before they left and they flew to where they needed to go. Artemis looked at Danny, "Why aren't you wearing warmer clothes?"

He looked at her, "My robes are made for most climates and cold climates don't bother me, plus they're traditional and I don't have them in just white."

The others looked at him strangely, but they landed which made it so he didn't have to answer any more questions. Artemis got ready and Miss Martian flew up in camouflage mode, she used her powers to break off the communications from the ship. The ship fell from the air and landed on the ground, 'Communications disabled, propulsion disabled.'

Artemis shot at it with a foam arrow and covered the large red window before the ship started shooting at everything. 'And ETs are sealed inside.'

Aqualad broke up the ice before landing on the ship, the cannon was about to shoot him but Wolf attacked it and forced it to aim away from him. Superboy held the canon in place and Robin jumped onto the ship and scanned the cannon, 'Identifying weapon structural stress points and links to the ship.'

After a few seconds Robin pointed to three places on the cannon and Miss Martian used her powers to break them. Danny used the Force to help Superboy get the cannon off the ship and he sensed something, before he could react Wolf pushed Superboy out of the way. Wolf was killed by the feedback from the cannon and everyone stared in shock, Miss Martian spoke, 'Wolf.'

Robin checked the scans of the cannon, 'There was no indication of feedback, I'm sorry.'

Superboy looked away for a second before he replied, 'Can't do anything for him now.' Superboy jumped back onto the ship and Danny helped him get the cannon off of the ship, once they got it off Superboy brought it over to the bio-ship. Miss Martian spoke, 'Rerouting systems to integrate weapon into the ship's bio-matrix, I'll need to de-camouflage for a few minutes.'

Danny sensed something, 'I sense a disturbance, something is coming.'

The heroes saw a ship coming toward them and Aqualad looked at Miss Martian, 'Miss Martian open fire!'

She looked at him, 'Can't, weapon systems are offline to incorporate the new cannon, and that's not fully integrated yet either.'

Artemis spoke, 'Got you covered, get inside.'

Artemis took an arrow out of her quiver and pointed it at the ship, she fired before running for the bio-ship and Danny's eyes widened a little. He jumped off the bio-ship and ran toward her as fast as he could, Miss Martian shouted, 'Artemis, behind you!'

Danny pushed her out of the way and was about to use the Force on the ship but he was too late, he got hit by the cannon. He felt everyone's shock and Miss Martian's panic before she shouted, "Danny!"

Danny woke up and immediately knew something was wrong, he could sense genuine fear and panic. They hadn't felt like that just minutes ago when he was with them, something had changed and it wasn't for the better. Danny looked at Batman, "Something is wrong, very wrong."

Batman didn't seem to believe him, "What are you talking about?"

"I can feel it, something is wrong, I can sense sadness, fear, anger, they wouldn't feel like this if they knew everything was fine."

Martian Manhunter spoke, "He is right, Artemis died in the exercise but she hasn't woken up, I believe she is slipping into a coma."

Batman looked at him, "Stop the exercise."

"I am trying but Megan has taken over the scenario, I can't stop it, I'll have to stop it from within the exercise itself."

Batman nodded, "Then do it." Martian Manhunter nodded and he went into Miss Martian's mind, now all they could do was wait. All of the older heroes looked a bit worried and Danny decided that he had to do something, he could use the Force to help.

It would at least stop the heroes from slipping too far into a coma for a bit, hopefully long enough for Manhunter to get them out. It would be difficult, and might kill him, but he had to at least try, so he sat on the ground like he would to meditate. He reached out with the Force and kept their minds working, keeping them awake if only a little so they wouldn't think they were dead.

He could sense when their emotions changed, there was hope, skepticism, disappointment, and a number of other emotions. He felt sadness coming from Robin the whole time, what exactly the cause was he couldn't be sure. When Aqualad and Superboy died in the exercise it became a little harder to keep assisting their brain activity.

Robin and Kid Flash died at the same time and if he wasn't being exhausted before he definitely was now. He felt his power slipping but he held on with everything he had and tried to keep them alive as best he could. He hoped Martian Manhunter would do something to wake them up soon, thankfully he did.

He sensed the heroes starting to wake up and he stopped using the Force, he opened his eyes and he saw the team getting up. Danny finally felt just how exhausted he was, he felt so weak that he didn't think he could stand. The young heroes looked around and Robin almost immediately spotted Danny and the Force user could sense his relief.

Robin quickly got up and walked over to Danny before hugging him which shocked and confused him. Despite that he hugged him back and Robin let him go, "You're actually okay right, you didn't die?"

Danny gave him a small smile, "I'm alive I assure you."

Batman helped Martian Manhunter who didn't look too well and spoke, "What happened in there?"

Martian Manhunter held a hand to his head as he spoke, "The exercise, it all went wrong."

Robin looked confused, "Exercise?"

Batman looked at him, "Try to remember, what you experienced was a training exercise. Manhunter psychically linked the seven of you within an artificial reality, you all knew this going in. What you didn't know was that it was a train for failure exercise, no matter what the team accomplished the scenario was designed to grow worse."

"Still you were aware that nothing was real, including the deaths of the entire Justice League."

Manhunter spoke, 'That is why you hardly grieved, even when Wolf was disintegrated before your eyes. But all of that changed when Danny died, though consciously Miss Martian knew it was not real her subconscious mind could not make that distinction. She forgot it was only an exercise and her subconscious took control making all of you forget too."

Batman spoke, "The only one that didn't forget was Danny."

They looked at Danny, "I was trained to distinguish between fiction and reality, I was pulled away from the exercise when I died. But I could sense your emotions and that was enough to tell me that something was wrong."

Danny tried to stand and when he did his legs gave out, Aqualad spoke, "But why do you seem so exhausted?"

Danny rubbed his eyes, "I used my abilities to keep you alive, I kept your brains active so you wouldn't slip into a coma. However it's very hard to do and the more of you that died the harder it became, the strain exhausted me both physically and mentally."

They all looked at Miss Martian and she looked sad, "I'm so sorry."

Superboy spoke, "This isn't her fault, why didn't you stop the exercise?"

Manhunter answered, "We tried, but Megan had a death grip on the scenario. Even Artemis, who should have awakened like Danny upon her death, was so convinced she had passed that she slipped into a coma. I realized I would have to rest control from Miss Martian's subconscious from within."

"But upon entering the reality I was overwhelmed by your collective emotion, there was too much noise to think clearly, to remember why I was there. The deaths of Aqualad and Superboy helped, but only when the mother ship exploded, and Robin and Kid Flash were silenced did my mind clear enough to remember my true purpose. To shock Megan out of the exercise before your comas became permanent, my apologies, I had no idea a training exercise could be so dangerous, so damaging."

Captain Marvel went to comfort Miss Martian and Superboy got closer but he didn't know what to do. Danny was silent, he wanted to tell her something to comfort her but wasn't sure what to say, if his masters were here they could help. Robin eventually helped him stand and brought him somewhere to rest, it didn't take long to fall asleep.
