Chapter One: The Beginning


Brigadier Lethbridge-Stewart: "Just once, I wish we would encounter an alien menace that wasn't immune to bullets." From the series Doctor Who.


Last time

Batman frowned " Who are you?" he questioned. "Harpy" she replied while spreading her wings and taking flight.

"Who would want to blow up the deep space monitoring network" asked Violet. "Aliens" Ivy deadpanned.

"What do you mean, I never even met you before today" a confused Nightwing pointed out. "I've been operating in your territory without permission, now we're even" Harpy clarified before flying off.


Ivy was annoyed. Violet had a new job at Star Labs and had forced Ivy to help her move to her new apartment in Metropolis. "Why couldn't you have gotten someone else to help?" Ivy asked her sister.

"Because, No one else I know has a car and a license" explained Violet.

"You could have hired movers" Ivy grumbled.

"I don't trust them with my stuff" Violet stated. Ivy rolled her eyes. "You could have asked Tara." she pointed out.

"Tara hates me!" Violet whined.

"So do most of the people that get to know you, we still put up with you." Ivy said with a smirk. Violet just glared.

After all the boxes and furniture had been moved in, Ivy looked out the window. "It's dark. This was only supposed to take a few hours and it took all day" she growled.

"You could stay here for the night." Violet suggested. "Fine" Ivy muttered.


Ivy was sleeping soundly on her sister's couch. Suddenly, she was woken up by a loud crash. She leapt off the couch and went to the window to see what was going on. She was soon joined by Violet.

"There's smoke and fire in the middle of the city, I'm going to check it out" Ivy informed her sister.

"More superhero stuff?" asked Violet. Ivy nodded before changing into her costume.


Harpy arrived at the scene just in time to see Superman save two police officers from getting squished by a leg that had emerged from the side of a meteor that had apparently crashed in the middle of the city. The leg was soon followed by two more legs and the rest of the body.

The being that had emerged from the meteor was tripod shaped and as tall as a building. It was white in color and had red splotches on its body.

The tripod then fired a laser that blew up a police car. Superman flew straight at the tripod but was sent sprawling after being hit by a laser blast. Police officers began firing at the tripod, but their bullets bounced right off. Seeing this, Harpy took action and flew toward the tripod while blasting it with fireballs that she released from her hands. She was soon joined in the air by a sleek black fighter jet which launched two missiles at the tripod. When the smoke cleared it was evident that neither attack had any effect.

The tripod began shooting more lasers and, while taking evasive action, Harpy noticed Batman in the cockpit of the jet.

"He's got to have a lot of money to afford that kind of toy." she thought to herself before Superman flew up and punched the tripod into a bridge, then began tearing through its shell, but he was hit with another laser blast and sent flying into building a before he could do significant damage.

The batjet fire more missiles at the tripod as it stood back up. The missles, once again, had no effect. Harpy flew as close as she could to the tripod and sent a fireball that twice as powerful as her previous attacks into the crack that Superman had made in the tripod's shell. Her tactic worked and the tripod exploded.

"Yes!" Harpy exclaimed, cheering for the apparent victory. "No!" she groaned as more tripods emerged from the meteor. "And Superman is leaving. At least the cavalry has arrived." she sighed as military jets and tanks arrived. "And there goes Batman." she deadpanned before going after them.


Harpy flew after the batjet in the direction she saw it leave in until she witnessed it land at a partially destroyed military installation. "Superman has lost his mind hasn't he?" she asked Batman as he exited the batjet. Batman ignored her and went into the building through a hole that had been smashed into the wall, a few feet from a door. Harpy followed silently until they came to a room full of people inside alien pods.

"Are they…?" she trailed off, unable to finish the question. Batman answered anyway.

"They're in a state of suspended animation." he explained before noticing the sound of something hitting metal and moving toward it.

Seeing Superman pounding on a reinforced steel door, Batman threw a batarang at Superman and it embedded itself into the wall next to him. Superman had turned around.

"What the heck is going on here!" Harpy exclaimed. "See for yourself" he answered before throwing the door out of the way, revealing a room full of computer screens that appeared to be monitoring someone's vital signs. Superman forced open the door at the other end of the room entering a room containing more computers and a green skinned alien.

"What is it?" asked Batman. "Mankind's only hope" Superman responded. He then flipped a switch that released the alien from its bonds. "He's been trying to reach out to me but that stasis field interfered. When his message finally broke through I came to rescue him" Superman explained.

"Why is he here?" Harpy inquired.

"The invasion" said a telepathic voice that caused Harpy to back up a step. "I came to warn you but I was captured and imprisoned. They wouldn't listen." the alien explained.

"Big surprise." Batman retorted.

"I sense you do not trust me, perhaps this will help" thought the alien before transforming into a more human appearance, complete with a blue high collared cape, blue briefs, two long ribbons that covered his chest stretching to two yellow buttons on his cape, a red belt with a yellow belt-buckle and a pair of blue boots.

"I am J'onn J'onzz" he introduced, speaking out loud for the first time while extending a hand in greeting.

"Don't take it personally, J'onn, he doesn't trust anybody" Superman explained when Batman didn't react.

"A wise policy" replied J'onn.


"We'll have to contact the joint chiefs." Superman said as they exited the building. They were met my a group of military personal.

"Stop right there Superman. You're trespassing on government property. Our orders are to keep that freak here" declared the leader.

"Wait, I'll vouch for him. You must let us go!" the man of steel exclaimed .

"I don't think so." said the leader.

"But the world's security may be at stake." argued Superman.

"That's why he'll never leave here alive." stated the leader as he and the rest of his platoon morphed into white humanoid aliens.

"It's them!" exclaimed J'onn.

The aliens began to fire at them but Superman got in the way and was blasted into a tank. Batman and J'onn took refuge behind a jeep then Batman threw an explosive batarang, taking out a group of aliens. Using the smoke created by the explosion as cover, Harpy threw fireballs the aliens that were still standing then joined Batman and J'onn behind the jeep. An alien got behind Batman but J'onn went through the dark knight and formed an energy shield that deflected the laser. Batman quickly pulled out a batarang and threw it at the alien, knocking it out.

"Are you alright?" Harpy asked J'onn, who appeared to be injured. Superman lifted a tank above his head and used it to defect laser fire

"Get him to safety. I'll cover you!" He shouted. Batman and Harpy took J'onn to the batjet and placed him in the cockpit. After Harpy and the batjet had taken off, Superman threw the tank at the aliens then left the base. They were soon pursued by a squadron of alien aircraft.

Superman took out one of the aircraft before getting by hit laser fire and slamming into the side of a mountain. Harpy shot fireballs at the aircraft and grinned when they exploded. She lobbed a few more fireballs at them while performing evasive maneuvers alongside the Batjet. One of the aircraft blew off one of the Batjet's wings. Harpy could only watch as the plane and its occupants were sent into a death spin.

Fortunately the downed aircraft was caught by a green energy field. Harpy sighed in relief before turning her attention back to the aircraft. A winged woman, that Harpy knew to be Hawkgirl, joined the battle and started bashing the fighters with her mace. Superman, Green Lantern, and J'onn also joined in the aerial battle.

Hawkgirl was blasted out of the air and landed on a cliff. A dark haired woman wearing a tiara protected her by deflecting laser blasts back at the alien planes.

"Who are the rookie in the tiara and the winged red head?" Green Lantern asked Superman.

"I'm not sure." responded Superman as he tossed one of the alien aircraft into the side of a cliff.

At the end of the fight, a red blur ran up carrying the Batjet's missing wing. "Hey Bats, I think you dropped this." said the blur as it came to a stop in front of Batman. The blur, having stopped moving, revealed itself to be a young man wearing a red bodysuit with a yellow lightning bolt on the chest, the Flash, obviously.

"Whoa, were have you been all my life?" he asked as the women wearing a tiara landed.

"Themyscira" she responded, oblivious to his attempts at flirting.

"The home of amazons. I always thought it was merely a legend" commented Hawkgirl.

"Many legends are based on fact" remarked Harpy, who had taken a position near the

Batjet and was inspecting the damage it had sustained. She hurriedly moved away when she noticed Batman glaring at her.

The dark haired woman nodded in agreement with Harpy's statement before she said "I am Diana, princess of the amazons. Themyscira is protected by the gods, but I could not idly stand by while the rest of the world was in danger." After Diana had finished speaking attention turned to Harpy.

"Harpy!" snapped Batman when it became obvious she wasn't going to say anything, as she was still distracted by the Batjet, even from a distance.

"What, I'm a mechanic I can't help it, machines are my thing!" Harpy exclaimed.

"That's not why you're yelling is it." she stated after receiving a look from the Dark Knight.

"You two know each other?" Flash questioned. "I work out of Gotham" Harpy explained off handedly. "I can explain more later. Right now we should focus on the invaders" she declared before anyone could ask more questions.

"She's right, we need all the information we can get on them" said Superman. And with that J'onn preceded to explain his history with the aliens while Superman repaired the Batjet's wing.


(If you know the series then you know J'onn's story and I don't need to put it here as it takes up to much space.)


"We've got to stop them, before it's too late!" exclaimed Green Lantern after J'onn . "It may already be to late." replied J'onn. Had finished telling the group about the invaders.

As if on cue a strange thundercloud appeared in the distance. "What are they doing?" asked Hawkgirl.

"The invaders are nocturnal. They want to blot out the sun so they can live in perpetual

darkness." answered J'onn.

"Friends of yours?" Flash jokingly asked Batman.

"This is no joking matter. Without sunlight crops won't grow. The entire planet could starve to death before the aliens get them." Harpy immediately responded.

"What's the problem, J'onn can just whip up another batch of nerve gas." Flash said defensively. "Unfortunately, I cannot. The gas can only be made from a rare Martian plant. I brought a sample with me, but it was destroyed when I was captured" answered J'onn.

"It would have been no good anyway. There wouldn't have been enough time to test the effects of the gas on the native plant and animal life." Harpy stated.

"We'll have to take out those factories!" declared Diana. "Exactly" Harpy agreed.

"This is no job for amateurs!" Green Lantern snapped. "Amazons are warriors born, want

to test me?" Diana angrily replied.

"Let's not fight among ourselves. John, we're going to need all the need we can get" interjected Superman before Harpy, who was glaring at Green Lantern, could speak.

"Fine, I'm sorry" said Green Lantern.

"Tactically we'll have multiple objectives, so we'll need to split into teams" explained Green Lantern. "Dibs on the Amazon" declared Flash while wrapping an arm around Diana's shoulders.


In Metropolis, near one of the aliens cloud producing factories, Superman, Harpy, and Hawkgirl, had taken down one of the tripods. Superman used one of the tripods legs to make a hole in the side of the factory.

"Let's go." Superman directed as he entered the factory, Hawkgirl and Harpy following soon after.

"Keep a sharp eye out." advised Superman.

"I always do." Hawkgirl responded as they walked deeper into the factory. Suddenly they were under fire from the invaders.

"Stay back I'll" Superman started to say but was interrupted by Hawkgirl launching herself forward with a battle cry. She quickly took out the aliens, much to Superman's surprise. "What?" Hawkgirl said after noticing the look on Superman's face "there's a time for words and a time for action."


"We're getting close. I can feel it." stated Harpy after she, Superman, and Hawkgirl had flown deeper into the factory. "Are you always so eager to fight?" questioned Superman. Harpy glared at him. "First, what I meant was I can feel their heat signatures, and second, I don't like the fighting so much as I like to blow things up." she answered, seconds before a shot went by. Looking towards the source of the shot, the group saw some fleeing aliens. After pursuing the aliens, the three were soon trapped by suddenly forming walls. The newly formed room was soon filled with noxious yellow gas, which caused Harpy and Hawkgirl to start coughing. Superman attempted to tear through one of the newly formed walls, but he was hit with a wave of electricity that sent him sprawling.


When Harpy regained consciousness she found herself unable to move. Looking around she saw that she was inside the alien factory, near a large red crystal, and was being restrained by something reminiscent of a giant piece of flypaper. Nearby Superman and Hawkgirl were in the same position.

"Hey, you mutated offspring of an amoeba! Let me go so I can kick your butts!" Harpy screeched at the nearby aliens.

"You shouldn't make them angry" Superman said. Harpy gave him a blank look. "The world as we know it is ending, I don't think making them mad will have any effect on our fates!" she snarled at him, then continued screaming insults at the aliens even as they brought in the unconscious forms Green Lantern, Flash, Diana, and J'onn.

After Green Lantern, Flash, Diana, and J'onn had woken up, one of the aliens stepped forward.

"Earth's mightiest heroes, welcome." it said as it changed into a familiar form.

"Senator Carter!" exclaimed Superman.

"Unfortunately the real Carter never returned from Mars." explained the alien.

"You used me to weaken earth's defenses." Superman stated.

"You were so eager to cooperate. Thanks to you the humans were completely helpless!" the Carter look alike gloated.

"You haven't won yet!" snarled Harpy.

"That's where your wrong." said the alien as the ceiling opened up allowing a ship to descend.

"All hail the Imperium." the Carter imposter declared before bowing along with the rest of the aliens.

The Imperium emerged from the ship, revealing itself to be a floating tentacled blob.

"J'onn Jonzz, its been a long time." commented the Imperium before J'onn was placed in front of it. J'onn was forced to transform back into his true form.

"Much better. You have defied us for centuries." the Imperium stated.

"And I will never bow to you or any of your kind!" stated J'onn.

"Then we will finish what should have been completed long ago, the elimination of the last Martian." announced the Imperium as its tentacles wrapped around J'onn and pulled him into the main body.

"Kneel to us J'onn J'onzz!" the Imperium demanded.

"Never!" J'onn declared.

"Why do you resist? Embrace this truth, after all these years you've finally lost." stated the Imperium.

"Have I?" questioned J'onn.

"You're hiding something, deep in the recesses of your mind." the Imperium said.

"Do I sense fear?" taunted J'onn. "What are you hiding?" the Imperium demanded as it shocked J'onn with electricity.

"Now!" J'onn shouted after changing back to his more human looking form.

There was an explosion next to the crystal, drawing everyone's attention. Batman was on the crystal. "It can't be!" said Diana in a shocked tone. "I mentally shielded him so he wouldn't be detected." explained J'onn.

Batman placed a device on the crystal that turned it blue. "What have you done?" asked the fake senator Carter.

"Reversed the ion charge" Batman responded.

"The crystal, Destroy it!" ordered the Imperium. Batman used his grappling hook to get out of the way just as the aliens started to fire. The laser blasts bounced harmlessly off the crystal.

"Its shielded!" fake Carter exclaimed. The factory sent up a beam of blue light that caused the clouds to dissipate. Sunlight began to pour in from the hole in the ceiling and the aliens began to burn. Some melted, while others ran for cover. J'onn freed himself from the Imperium and dragged it into the sun.

"You live underground and shun the light! Why, does it burn your pale putrid skin?" yelled J'onn.

"Ultraviolet rays, coming from deep space, they have no resistance against our sun's radiation." explained Batman as he began freeing Diana. "So you did find a weakness after all." Diana stated as she took over the job of freeing herself.

"Destroy them!" the Imperium demanded. The aliens began to fire at them so Superman lifted part of the platform the aliens were on to shield the heroes that had yet to be freed. The man of steel then used his heat vision to free Hawkgirl. Hawkgirl used her mace to free Green Lantern and Harpy, while Diana freed Flash. The heroes then began attacking the aliens with their respective powers. Superman bashed a hole in the roof of the factory in order to let in more light. Diana and Green Lantern soon joined him.

Meanwhile, the Imperium had gotten away from J'onn and had retreated into its ship. Diana used lasso to catch the tail of the ship and slow its ascent. The ship fired a laser that caused Diana to lose her grip on the lasso. As the ship began rising again, Hawkgirl flew in front of the ship and began smashing it until it fell into the factory nearly crushing Batman but Flash rescued him.

"Maybe we better get out of here!" exclaimed Flash as the building started to collapse.

"Not without them." stated Superman, drawing attention to a number of people that were trapped in cocoons. Superman cut them out of the cocoon.

"Flash, Harpy give me a hand." Superman ordered. Harpy and Flash each carried a victim to Green Lantern who used his ring to make a protective bubble around them started to fly out of the building with the rest of the Superheroes. Superman was carrying Flash, and Diana was carrying Batman. The rest following them, getting out minutes before factory exploded. They watched light shine onto the city.


Over the next few weeks the group took out the rest of the facilities that were scattered around the world.

After a month all of the invaders and been destroyed or had retreated. But people still feared the possibility of it happening again. Fortunately Batman came up with a solution.

At a space station above the earth Superman was looking out a large window at the Earth. Batman that walked up behind him

"Incredible… do your stock holders know about this Bruce?" he asked the dark knight.

"A line item hidden in the aerospace R&D Budget. This watchtower will act as an early

warning system for detecting other threats of invasion from space." responded Batman.

"And its got a fully stocked kitchen" added Flash as he and Wonder Woman emerged

from a nearby elevator.

"Iced mocha?" he offered Superman.

"No thanks" the man of steel politely declined. Diana took a sip of the drink in her hand

"Hm, they don't have these on Themyscira."

"Stick around princess. I'll show you the ropes." offered Flash.

"Perhaps I will." she responded.

"An impressive installation." commented Green Lantern as he descended with Hawkgirl and Harpy. "It's a masterpiece. But what's it got to do with us?" questioned Harpy.

It was Superman who answered. "I once thought I could protect the world by myself, but I was wrong. Working together we saved the planet and I believe that if we stay together as a team we could become a force that fights for the ideals of peace and justice."

"What, like a bunch of super friends?" asked the Flash getting the idea.

"More like a justice league." Superman said with a smile.

"Do you have any idea how corny that sounds?" voiced the Flash again. "But maybe the big man's got a point, with all of us behind it, it might just work. Count me in." he stated putting his hand on Superman's.

"Me too" said Green Lantern approaching them and putting his hand over Flash's. Hawkgirl followed his example "And me" she said placing her hand on Green Lantern's.

"My mother may not approve, but I find man's world to be intriguing. I'll gladly join." Diana declared before placing her hand on Hawkgirl's. Harpy frowned apparently thinking it over. "Alright. I'm in." she stated after a minute, then put her hand on Diana's.

"What about you Batman?" Superman asked.

"I'm not really a people person. But when you need help, and you will, call me." the dark knight responded.

"Understood. Then we're all agreed" stated Superman. Diana looked around "Wait J'onn is not here."

"Yeah, where is he?" asked the Flash. Superman flew to the high control console that J'onn was at.

"J'onn are you alright?" asked Superman.

"My family and loved ones are long gone. I am the last of my kind." said J'onn. Superman placed a hand on his shoulder.

"I know the feeling." he said supportively.

"Mars is dead, and I am alone in the Universe." J'onn continued

"J'onn, we can never replace your family you lost, but we'd be honored if you learn to call Earth home." offered Superman. They both smiled and went down to join their new teammates.

"You know Harpy" Flash began as the heroes gathered together "you never did explain where you're from."

"She's from another dimension." explained Batman.

"How do know that?" asked Green Lantern.

"Nightwing told him." Harpy answered with a sigh. "Did he tell you everything or just the inter-dimensional part" she asked Batman.

"Everything, except what you're doing here" Batman said. Harpy shrugged. "Some of the other clans in Spero thought it would be a good idea to reconnect with our old home worlds."

"Home worlds?" interjected Flash.

"My race was originally from this dismension. My clan still has a bit of a grudge against humans so we usually stick to the business sector." she explained.

"You didn't." commented Diana.

Harpy frowned. "I like humans" she replied.


Ivy was sitting on the couch in her apartment when the phone rang. She it picked up.

"Somebody's in trouble" sang the voice on the other end of the line.

Ivy sighed "What are you talking about, Violet?" she demanded.

"Harpy joined the Justice League, but Ivy didn't talk to Demetri or Tara first" Violet explained, giggling at the end.

"I'm a grown woman. Why would I need to talk to either of them about my decisions?" Ivy snarled.

"Because we both outrank you" growled a new voice.

Ivy's eyes widened. "Tara, um you're not mad are you?" she asked in a slightly panicked tone.

"Let's see… we're not at war, there aren't any big crises, and, if we spin it the right way, this could be a good way to get the Adler's to branch out more. So no, I'm not mad, in fact let's call it your new assignment." Tara declared.

"Really, why?" Ivy inquired. "Because it makes it easy to check up on you, and you'll get more pay, which we all know you need. Your first mission report is due at the end of the week. Bye" Tara said quickly then hung up.

Ivy pinched the bridge of her nose. "Paperwork, great" she groaned.


So, in case you missed it, Ivy's home world is named Spero, which, according to the internet, is Latin for hope. Oh, and Adler is German for brave eagle.
