Earth-1
Central City
S.T.A.R. Labs Hanger
Everyone attended, making their conventional stances, awaiting for given orders, or plans.
Felicity, walks passed, looking at every member. Announcing the names of each team. Team Arrow, Team Flash, and Legends.
"Is that all of them?", Felicity, dispute, asks.
"I think so", Harrison said, with inability.
"Nate and Amaya are back watching the waverider", Sara addressed. Everyone in her team agreed. "The newbies", she called.
Suddenly a spiral tube opens.
"Hey isn't that...?", Felicity directed Harrison and Caitlin to. Followed by Team Arrow and Team Legends.
"No", Caitlin retorted. "That is way different from what Cisco buzzes".
As Caitlin addressed the differences, Team Arrow and Team Legends mark their respective fighting stances.
In it, 5 figures stepped out, calming everyone down, when they saw Thea, Cisco and Barry.
For the other two. One was a woman in blue vest from her shoulders down to her legs, with a red cape. A triangular plate of S. As for the last one. Majority were going to smash their jars. Cause what they saw is someone they never thought they'd see.
"Fucking can't be!", Sara yelled. "It can't be!".
John and Laurel were spooked.
"Oliver?", Felicity quietly called. "I can't...impossible".
Others like Rene, Evelyn, Mick, Rory, Ray, Curtis, Iris, and Harrison. They were very confused. Some of them knew Oliver's descriptive life, they just didn't know why a former spoiler rich boy would be doing here.
Sara, couldn't notify what she feeling, she straight away ran to him at full speed. Oliver noticed it, as he too was astonished to see her.
Sara and Oliver, gripped into a tightening hold over each other.
"How Oliver?", she cryfully questioned.
"It's a long story", Oliver simplified, glancing over Diggle and Laurel, giving them brief smiles.
"What's a spoiled rich boy like him doin here?", Mick demanded.
Ray steps close to Rory. "That's no spoiled rich boy. He is the Arrow". Ray once affiliated with Oliver, though it was only, as it was prior to his presumed death stage.
"We worked with him in Star City", Jefferson reminded, referring to a different Oliver Queen, who showed them that he still lived. "2046".
As soon as Sara and Oliver separated their hugs, Sara glares over to Barry. Barry noticed it, the anger that lodges inside her.
"Why didn't you tell me Oliver was in another world?", Sara questioned. "I mean I knew he was alive when I went to the future, by accident from some malfunction in the Waverider, but still I was never told where he's been".
Barry wasn't able to escape from Sara's wrath. He once heard, after Sara's resurrection from the Lazarus pit, that Sara was linear to her brutality, that it feared her own sister. Barry was saved, thanks to Oliver wavering it down.
"My history will be talked", Oliver commanded, transitioning to filling the gap behind it. "After we save our world from aliens".
"Who's the pretty girl with the red blanket?", Mick pointed.
Barry, knowing who Mick was referring to, went by Kara's side, only to achieve Kara's extend arm, to stop him. She knew Barry was going to reveal her secret identity, which she wasn't keen to pick on.
"Let's just skip the introduction", Kara commanded, crossing her arms on her chest. "Like what Oliver said, we have a planet to save from".
Majority didn't rate Kara's behaviour, like she was ignorant, less social, more thirsted in planning. A mode that drifted Oliver into a slight unhappy phase.
"For all you need to know", said Kara. "I am Supergirl. An alien that has powers beyond those of mortal men". Kara quickly showcased it by flying, and shooting a laser.
"Best team-up ever", Felicity excites, ignoring the fact she was very rude.
Everyone staged in awe, learning that they're working alongside an alien. First time for them. Third time's a charm for Barry.
Oliver was tempted to have a word with Kara, but now wasn't the time. They've got an alien to crash against.
Unbeknownst to anyone in the hanger, a Prometheus watches over them, like a Hawk, on top, by the glass-screens. Being very stealthy. He zooms a closer peek on someone he was looking for all this time.
"There you are, Oliver Queen", Adrian exhales. "I could end you with a percent of my power. But that won't be necessary. Not now". He instantly faded.
An hour had passed. The temporary league grew accustom to their positions. They all positioned like unfollowed droids, in front of the screens Cisco was soon bout to display. Oliver approved Cisco's head-start presentation.
A projection of humanoid flies.
The images Oliver and Kara discern, they were paralysed. The figures were blurry, but it was enough for them to plain it in their visible eyes.
"So apparently", Barry began, being the man to take the job, as presenter. "The UN have no idea who these aliens are as they've never faced an army like that. We can all easily assume they're flyers from another planet".
"They are not just flyers from another planet, Barry", Oliver addressed. Every boldly looks to Oliver, wondering if he had any ties.
Kara clenches her teeth, she clenches her fist. "They're Parademons!", Kara growled. She instantly hammered a nearby table, scaring the beans out of everyone, minus Oliver. The gauge energises. Kara emits a rage-heat-vision, to her left side. Its crimson variant blew a big spot on the wall, creating a whole. She cries.
Oliver paces to her point, wrapping her arms around her torso.
"Kara calm down!", Oliver said. "Calm your anger down! It's going to get worse!".
Kara, hearing Oliver's words, leisurely, calms down. Inhaling his breathe. The two close their hugs.
The rest are laboriously confused and stuttered.
Felicity, perceives their gap-close, hinting her jealousy out of it.
Kara carries on with her breathing, haunted by her own actions.
The league, advised by Barry and Sara, motioned to await Oliver's arrival.
Oliver steps out of the bunker, he placed Kara in.
Oliver walks back to the league Barry formed.
"Is she alright?", Barry, intermediary, asked.
Oliver briefly catches his breathe. "She will be fine. She just needs to inspect her own space". He sharply levels with Barry. "Sorry about her-".
"It's fine, don't worry", Barry gestured.
"You've grown quite fond of her, in that other world", Sara remarked, elbowing the upcoming man of arrows. "Last time I recalled, you were that pretty boy who was really stubborn. Less precise to sharing his space with people".
"Like I said: it's a long story", Oliver kindly repeated.
"So mind spilling the beers on who where digging in?", Rene questioned, with a rude tone.
Oliver went into the depth of story regarding himself and Kara facing against those things. More exact on Kara's catalogue of histories she encountered with them. He explained these Parademons are creatures faced from Supergirl's planet. And assumed a chance these aliens they faced are from her world.
"A new tier list of rogue galleries", Thea quoted, making Oliver grin at her quote.
"Facing monster that are impossible to make them extinct. We could use Supergirl as a training wheel", Harrison layed out, trying to be of a good value.
"Absolutely not!", Oliver yelled, scaring him. "Kara will show up whenever she feels she has the will power to do so". His line was noted in everyone's heads. More reliant in Barry's brain. "However we will start a training shift. Test each other's skills and-".
"Since when was Robin Hood calling the shots", Mick rudely interrupted.
"What I think Mick is trying to say is it would be nice if we knew who's in charge around here", Jefferson corrected, with a softer voice than Mick's.
"Maybe we should take a vote", Ray offered. "Choose a leader. Someone we can all trust".
"Well I trust Oliver", Cisco said, way disloyal and less patches to touch in Barry's service. "He's got my vote".
Iris signifies her eyes to Barry, latter pouring his head down.
"Appreciate that Cisco but Barry put us all together it should be him", Oliver announced, with pride and loyalty to his good-turned-best-friend. "For now".
Barry stitches his face in amazement and concern if his friend wanted him to be their temporary leader.
Oliver nodded, accepting his permission.
Once the deals were done, the league resolved into their followed standards, led by Barry, who was instructed by Oliver, as he knew more about the followed standards more than anyone in here, in line to Diggle. A moment that amused Sara, Diggle, and Thea. Standards incorporated to to learn knowledge from each other, and to rely on each other. First time any of crossover batches of teams into one giant league.
