Here's the final part of this three-part starting point, enjoy.

Invasion Part 3

(In Metropolis)

Batman was frowning deeply at this as he says, "We need to get back to Gotham, and quickly. Come on, Robin." Robin nods as the two went to get to the car, but was stopped by Flash.

"Whoa there, Bats. You think we're just gonna let you take this over sized piece of firewood alone?" asked Flash.

"Indeed…it took both of you and Superman to beat one of these creatures." Said Manhunter calmly. "And by the sounds of it, it is large."

Batman just frowned as he says "Fine…but as long as this is only a one time event."

"Deal." Said Aquaman with a nod. They then saw a black haired woman with a blue suit shirt and skirt came out.

"Lois." Said Superman as he came over to her. "Listen, I'm needed in Gotham right now. Give this to Mr. White." He handed him a small device. "Lets go" he said to the others.

"I'll call Dia-Wonder woman quickly." Said Batman calmly as he got his communicator out.

"Oh-ho! Calling your girlfriend, Bats?" asked Hal with a laugh as Flash and Robin both chuckled. Batman just scowled a bit at this as he gave them a glare, which shut them up quickly.

"The Batglare! It burns!" said Flash in an over-the top tone as he chuckled. "Come on, let's make a plan. How long can Spoiler last with it, Oracle?"

Barbara, who was still on the line, says "With her skill sets and gadgets, I think she can last for about the time it takes for the Batmobile to get from Metropolis to Gotham."

"So…20 minutes?" asked Flash.

"Yep." Said Barbara flatly.

"Great…Supes, we'll go ahead." Said Flash.

"Alright…you guys catch up when Wonder woman answers." Said Superman as the two quickly left; Superman in the air and Flash on foot, moving at super sonic speed, breaking the sound barrier as they did so.

"That should buy us some much needed time." Said Batman calmly. He took his communicator and began to type some numbers on it as he waited.

Then a woman's voice answered. "Yes?" asked the voice, which the group recognized as Wonder Woman. "Bruce?"

"First name basis?" asked Robin with a laugh, as Batman glared at him calmly.

Batman then says to Wonder Woman "We need you in Gotham as Soon as possible."

"I take it involves the aliens that have been popping up?" asked Wonder woman, as the silence was the only answer she got. "I'll take that as a yes. I'll get on the fastest jet I got to get there. While I can fly myself, a jet is a lot faster than I am."

Batman nods as he says "Understood." As he hung up, but saw Lois was smirking at him. "What?"

"So…what's this thing between you and Wonder Woman?" asked Lois with a smirk, as she says, "Come on, rich boy. I know you and her have a thing, even if the press says otherwise…"

"You mean about the thing with Superman and Wonder Woman?" asked Robin, curious. THAT got him a death glare from both Lois and Batman, as he backed up nervously.

"So, what other relationships have you been in?" asked Lois.

"Is this really the time to do this, Lois?" asked Batman calmly as he went to his car with Robin following.

"I'll let you know if we visit again." Said Robin with a chuckle as the car closed. Manhunter lifted up Aquaman with his telepathy and flew after him, with Hal following.

(Meanwhile…in Gotham)

Spoiler groaned as she tried to get up, with the large monster glaring down at her. The creature appeared to be a large, mangled mass of bark and roots taking a humanoid form that had a thick head with a Jack O'Lantern face with a jagged mouth and triangular eyes, which narrowed a bit as it hissed, yellow mist coming out of his mouth as thick green leaves grew on his head.

The large creature was about to stomp at Spoiler, but a red blur moved her out of the way. Spoiler blinked in shock as she saw she was being held by Flash, who just smirked. "Need a hand, kid?"

"Thanks Flash, now put me down." Said Spoiler with a flat tone. Flash does so as Superman flew in and delivered a hard punch, but saw it barely dented the wood.

"Nice try…" said the creature with a growling tone as he breathed out a large gust of yellow powder, covering Superman in a layer of bark.

"Supes!" said Flash in shock, as the bark began to crack before Superman broke free.

"Well, that was weird…" said Superman, frowning a bit as he fired a heat vision blast from his eyes, making the creature growl darkly at this in annoyance as it felt the heat on it's roots, making it roar and smacking him away.

Superman grunted a bit as Flash ran forward quickly and began to send a barrage of punches at it's leg, but was only kicked away. "OK…punching it's roots…bad idea…" He said with a cringe.

Spoiler then asks "Where's Bruce at?"

"He's coming, don't worry Spoiler." Said Superman as he flew around him and blew out a breath of cold air, but the creature breathed out the yellow mist from it's mouth to counter it, making the mist turn into ice instead of himself.

"It's pretty smart…" said Flash with a frown, as Spoiler got up and got out some marbles out of her thigh belt and threw it at the large tree's feet, making the bark burn slightly but no fires formed. "WOW…you burnt it slightly…nice job." Said Flash flatly.

"Oh like you did much on it!" said Spoiler with annoyance as she was slapped aside by a root as Flash sped forward and ran up it's side and tried to punch it, but got breathed on, making him get covered with bark and fall off, the bark crashing off when he landed.

"OK…that was a dumber idea…hmm…" Flash looked around quickly, as he heard an engine coming form the distance. "That is one fast car…" He said as he turned and saw the Batmobile arrive with Robin and Batman coming out.

Robin ran over to Spoiler as he asks "You okay?"

"Yeah…" groaned Spoiler as she got up, with Aquaman, Martian Manhunter and Green Lantern arriving. "Oh joy…you got the two green guys and the fish man…just who we need to fight a walking tree."

"We just need Wonder Woman and we'll be good." Said Batman. "We just need a-" He then saw Hal fly right for it. "-Plan." He finished flatly.

"I got a plan, Bat's. It's dethron this over-sized plant." Said Hal as he made a giant chainsaw contsturct with his ring and tried to cut through his roots, making the creature hiss in annoyance and pain from the blade hitting the bark, but he breathed a yellow vapor on him, making the construct deteriotate. "Gah…yellow powder…wait, the hell?" he asked, as he was frozen next, making him fall to the ground.

"Hmm…that could be a problem…" said Batman as he got some thermite grenades out. "Clark, follow me. Robin, you and Flash distract it down here." Said Batman as he fired his grappling hook into the side of a building and quickly shot upward, with Superman following.

"what is he doing?" asked Flash as he dodged more attacks, as Robin smirked.

"I got an idea…" said Robin with a grin, as Batman looked inside of it's mouth and threw the grenade inside of it's mouth.

"Now Clark!" said Batman as Superman's eyes turned dark red before fiering a beam of hot energy at the grenade, making the explosion twice as powerful as it exploded in it's mouth, making it roar in pain as it began to cough and hack, releasing black smoke instead of yellow mist.

"Alright! Lets do this!" said Flash as he tried to run at it again, making his fist vibrate like crazy to add some more power to his punch.

"I'm with you there!" said Hal as he fired a blast of energy, making a giant fist…which accidently hit Flash when he was just about to punch it, sending him right into it. "Oh crap…"

Flash groaned as he was flicked off, making him crash into Hal. "OK, GL…question: What the hell was throwing me into the monster for?"

"Hey, it was an accident!" said Hal as the two glared daggers at the other. Aquaman just rolled his eyes as he ran at it, dodging the attacks as he summoned some waters from a near-by pipe and made a sword out of it and slashed at it's leg, trying to cut through it, but the large tree just growled.

"Arthur, attacking it with little to no stragety isn't wise." Said Manhunter calmly as he fired a heat vision blast of energy at it's arm, making it growl more.

"Stay out of this, J'onzz." Aquaman warned as his blade began to pierce it's armor.

"Dude, that's going to take forever." Said Flash as he began to rapidily punch it in the other leg, as Hal fired energy at it. All the while Superman, Batman, Robin and Spoiler all just watched with flat expressions.

"How long do you think they have?" asked Spoiler flatly as she saw Hal and Flash get smacked aside while Aquaman and Manhunter got wrapped in roots.

"Not long…shall we?" asked Superman as he picked up Batman, as he nods. Superman then quickly threw Batman into the air, as Batman opened his cape to glide over the creature before throwing down six batarangs, which made contact with the roots before exploding, causing it to let go of Hal as Manhunter phased out of the root.

"Well, this is going smoothly." Said Spoiler flatly as the other heroes nod with a groan, as the creature growled darkly at them.

"Where is Diana?" asked Aquaman, as he dodged a root that was about to hit him. "I thought she would be here by now."

"She's in Israel at this time, Aquaman." Said Batman calmly. "A jet can only go so fast from there." Suddenly a white light came into view as Wonder Woman flew out, looking at them calmly.

"…how…?" asked Flash, as he began to point to her and then to the area she just appeared at as the portal closed.

"It's a new technology CADMUS is experimenting on. Based on the technology that brought J'onn to earth." Wonder Woman explained. "I was the first tester of it."

"Thank god you didn't grow a third arm." Said Robin as he threw out some batarangs at the large creature, who just growled in annoyance from the attacks.

"OK, the way we've been fighting it has been proven to be ineffective." J'onn said calmly, a frown present on his usually calm face.

"Well, if Mr. Fastest man with no brain alive here, I would have gotten him." Said Hal, as Flash glared.

"Watch it, Limabean boy! I can take this thing out at the time it takes you to blink!" said Flash as he quickly ran to the monster, who just slapped him aside.

"Did I blink because I think I missed you beating it up." Teased Hal, as Flash gave him a glare.

"No one likes a smart-aleck, Hal." Flash said, glaring at him as he got back up. Aquaman then fired sharpen tipped water and stabbed into the creature's arms, making it growl in annoyance as it slapped them aside, but Superman and Wonder Woman stopped the vines mid-throw and tried to push back.

Batman studied it as he says "Clark, use your X-Ray vision. Try to find weakspots." Superman nods as his eyes flashed a bit, as he looked around.

"I see a few. It's right above the rib cage, in his elbows and his knees." Said Superman, as Batman nods.

"Flash, take out the one in the left knee, Hal, the right elbow, Manhunter, the other knee, and Aquaman to the other Elbow. I'll take out the rib area. Robin, Spoiler, you're with me. Superman and Wonder Woman! Keep it situated!"

The two nod as they held on tightly as Flash ran quickly and began to punch the kneecap like crazy. The creature growled in pain at this as Hal and Arthur began to attack the elbows and Manhunter fired blasts of energy at the other knee.

"Now Robin, Spoiler, throw thermite Grenades at it's chest at my command…" said batman calmly as the two nod and got out their thremite grenades. "Wait for it…"

Flash's last punch broke through as he spun around it, as did the blast from Manhunter, as the legs began to give way, as did the arms. The chest became a clear target as Batman says "NOW!" AS he and the two threw their grenades.

The bombs made contact as Superman blasted them with his heat vision, causing a giant explosion of fire to erupt around it, making it roar in pain as it's body began to burn up.

"And now…to give it some more fuel…" said Flash with a smirk as he noticed a gasoiline truck. "Hey GL, I got an idea!" as he ran over to it and began to unhook it. "Okay! You're good!"

Green Lantern flew over and picked it up. "Shall I, Bats?" Batman saw this and…gave a smirk.

"Knock yourselves out. But contain that explosion." Said Batman as Hal nods as he tosses it up, as Superman flew up and caught it as Hal made a dome that has an opening so he can drop it in.

"Fire in the hole!" said Flash as Superman threw down the Gas tank down into the dome which made contact with the tree monster's head, as the gas leaked out and ignited the tree more, causing it to burn up quickly as the truck exploded, as Hal capped it to contain the fire as he grunted.

"Okay, this is a big one…" said Hal as he tried ot keep it together, as the dome nearly shattered from the force of it, but Hal resisted it for awhile before the dome began to break more.

"Flash, Superman, I need a tornado to keep that explosion contained!" said Batman as the two nod as they began to go around the dome; Flash by foot and Superman by air. Soon the two red blurs began to make a tornado as Hal let go of the forcefield.

Suddenly a giant burst of flame shot into the sky, as the large tree creature was now black and white coloring with burning leaves still as the tornado stopped.

"Is he…" began Spoiler as Manhunter kept his distance from the burnt pile of wood. The wood monster than fell forward, falling apart ash e did so.

"Whoa!" said Superman as Hal picked it all up. "That was too close."

"Big time. Now to take out the trash!" Said Hal as he shot into space and says "Sayonara, woodman!" He then chucked it towards the sun, where it fell apart as he flew back down to earth. "Well, that was one invasion down the tube."

People walked back into the main square at this, as they saw the heroes standing where the monster once was. Then everyone began to cheer.

Just than a few people with cameras and microphones appeared. "Ah great, the paparatzi. I guess we're gone." Said Robin ash e and Spoiler began to leave, but were stopped by a bunch of kids. "Gah!" he said in surprise.

"Okay…we're stuck…" said Spoiler as a red haired woman dressed in a black jacket with a white shirt under it, a black skirt and red shoes. Her dark blue eyes and slightly freckled face smiled at them.

"Hello there, I am Vicki Vale of Gotham Star." Said the woman, known as Vicki as Batman nods calmly.

"Hello Miss Vale, I haven't seen you in awhile." Batman said calmly as Wonder Woman just raised an eyebrow at this.

"So what do you want, miss?" asked Martian Manhunter calmly.

"I am actually very curious…is this a sign that the best heroes out there are going to be joining forces to help protect people from threats like this?" she motioned to where the monster once was.

Batman looked at the other heroes and looked to everyone around him. He sighed a bit as he thought 'There will always be a larger threat out there…one we cannot handle alone…' He then looked up at this.

"Yes…we are going to be a team. But only when the time is needed for us to be." Batman said calmly.

Vicki nods as she turned to the Camera and says "You heard it here first, folks! Gotham's very own Dark Knight, Batman, along with Robin and Spoiler have officially joined forces with the greatest heroes on earth. So…what is this team you are going to be part of?"

"I got this, Bats." Said Flash as he patted his soldier as he came over to Vicki. "So that I can honor my predecessor, the very first Flash, I can safely say I know the perfect name for our team."

"and that is?" asked Vicki, confused.

"The Justice League!" said Flash, though Batman cringed slightly at that name.

"So here we have it folks; the Justice League, the earth's newest champions!" said Vicki to the camera. "So I am curious…what is next for this heroic team. This is Vicki Vale…signing out."

(Meanwhile…in another city)

In the city known as Jump City, California, in a tall, T-shaped building, a young man sat down infront of a large TV as he just saw the last bit of the news segment that Vicki had just said.

"Hmm…" Said the young man calmly as he got up and turned on the light, revealing himself to be a young man around 20 with neck length black hair, dark blue eyes and a black and blue jumpsuit with a blue, eagle-styled insignia on his chest nd blue pads on his gloves.

He took a picture from a table near him; one of a slightly younger batman with a boy who looked just as serious as he was, but with a slight smirk, a red vest with a small "R" on the right side of his tunic, a yellow and black cape, green pants, and pointed green shoes.

He smiled a bit before sighing. "Has it been 5 years since I left? Really?" He sighed as he walked over to a computer and began to type. "Bruce…this is a message from…" He tapped the table lightly as he looked at the picture.

"Dick? What's wrong?" asked a voice from down the hall. The young man looked at the computer before turning.

"It's nothing Kory, I'm coming." Said the young man, revealed to be Dick. He then sighed as he looked at the picture and a small tear rolled down his cheek, but he wiped it quickly. "Bruce, this is a message from your…son, Dick Grayson." He continued to type as, on his desk, was a batarangs and a domino mask that was still on the table.

Little did he know, however, this was just the beginning…
