It all began when a green-haired girl and a blonde-haired girl fighting each other. The blonde threw her fist at her opponent as she swiftly dodged with her acrobatics. "Is that all you got, Terror?" Taunted the girl with green hair. Only for her to dodge again as Tuppence Terror creates a hole on the ring. Causing the floor to crack into pieces.

Tuppence then swing her fist into an uppercut after charging at Emerald Sustrai, the girl with green hair. But when her fist meets her face, it turned out to be an illusion when Emerald seemingly disappears.

"What?!" Tuppence gawked in astonishment. Emerald was behind her and twirls around Tuppence and makes the corcle throw. "Kyah!" Emerald shouted. "You're gonna get it, Sustrai!"

Tuppence lets her anger get the best of her while her twin brother, Tommy cheers her on awaiting his next match. "That's it, Sister Tuppence! Show her what a real Terror is!"

But the more Tuppence attacks Emerald. The more she only keeps hitting illusions. "Hold! Still!" She performs a high kick, but to no avail as the real Emerald makes the sweep kick under Tuppence's feet, causing her to fall back. "A Terror? Can't live up to your name, can you?" Emerald said it with a smirk.

Emerald can only focus in exhausting Tuppence's fighting energy by creating illusions to tire her out. But when Tuppence has enough, she resorted to put Emerald in a headlock. "Not so tough now, aren't you, Sustrai." Tuppence panted happily to finally defeat the thief.

But Emerald turns the tables as she performs a hip throw on Tuppence as she spins and throws her to the floor. Then Emerald kicks her on the face. Causing Tuppence to fall again.

"Tuppence!" Tommy runs to his sister, and check for her injuries. Emerald steps back as the twin siblings stood in shock. Even with super strength, Emerald was too smart to give up easily when she could have forfeited the match. As Tuppence gets up, Tommy tried to help her up, but she slaps his hand away. "Forget it, Brother Tommy. We're out of here." She snarled, angry for losing the match.

The refree then grabs Emerald's hand and raises it to announce her as the victor. "Winner! Emerald Sustrai!" Said the refree.

Then Emerald was paid for winning the match. And left the alleyway of Gotham City. "Finally, some cash. This is totally better. Mom is gonna have her mind blown when she sees this. This could save the Jewelry Shop if I won more." She stated.

Emerald then hears a screeching sound. It was a car. Stopping in front of her. "What the–?!" Then a group of people in armored suits and weapons hopped off the car. Then more emerged behind her. Then Emerald sees the emblem on their armor suits. And her eyes widened and recognized the symbols. "That symbol..."

But before Emerald can ask herself. One of the combatants in suits swung his arm behind her, and Emerald ducked under and springs a kick behind him. Emerald shifts away to get into a stance.Then Emerald performs a throw over her shoulder as another combatant charges at her with a saber sword. But Emerald steals it and lands a punch on him.

One of the armed combatants scanned Emerald using visors from their helmets. Predicting her abilities and every move she makes. Then it becomes complete and shares it with his comrades to defeat Emerald.

"Accessing: Emerald Sustrai."

Emerald then takes out her pistol blades and spins them to fend off. "Back off, you freaks!" But none has replied, nor did they repond. Emerald figured they had something planned for her. But doesn't know what it is yet.

"Alright then, you asked for it." Emerald warned them fiercely. Shifting her blades into chains. But one of the enemies had got a hold of her chains and pulled her in. "Ah!" Emerald wasted no time to land a kick on the enemy in front of her. But he disappeared in a similar fashion of her illusions. "What?"

Emerald landed on her feet. Emerald then proceeds to swing her blades. But to her shock, their suits also summoned pistol blades similar to hers. "Oh, you have got to be kidding me!" Emerald exclaimed.

She clashes her pistol blades against the strangely suited men. Then some had disappearsd and shifted to another spot. "Hey!" Emerald shouted seeing this and throws chains at them. Swinging them around her.

But they swarm around her and run in circles. Confusing Emerald. And then one got to her and knocked her out. "Ugh!"

Earlier

Elsewhere in a main room of the Mishima Dojo, an elderly, but also muscular man is greeted by Lex Luthor. "Mr. Mishima, Mr. Luthor is here." Said a security guard. The main head of Mishima Zaibatsu, Heihachi Mishima, meditates until he gets up and turns to the bald billionaire.

Lex bows to Heihachi in respect. "Mr. Mishima. How wonderful it is to see you again. A comfort for your loss of your son, Kazuya." Heihachi bows back as they look at each other to talk about the matters at hand. "Lex, my old friend. It had been years since we last spoken. I supposed there is something you had in mind."

"You and I have an issue when it comes to dealing with our adversaries." Heihachi comes to the realization of how Lex sees anyone who he sees and deems inhuman. Something his bloodline is cursed with. "Adversaries you say? As much as I want to find out more. I have more enemies to deal with."

Heihachi seems to have a dealing with his own issues. Lex sees that Heihachi is not bothered by his son's "death." Which for some reason what he is looking for. He is a perfect addition to The Light organization. "I have some partners who want to meet you. Ones that might take interest in your agendas."

"And who are these associates of yours?" Heihachi asked. Wondering if Lex is planning something bigger. If he does, itnwill be an oppotunity for him to prove to the world that the Mishima weren't to be bested, nor to be beaten. Either way, gaining alllies and eliminating them is his way of winning.

"That is for you to choose. If you meet my partners, perhaps you can be part of something grand. That is, if you can accept their hand in friendship." Lex said to him.

Author's note: The characters in Tekken in my fanfic are not from the main Tekken universe. But the versions from Earth-16 where the YJ story took place. Needless to say, in this version, Heihachi Mishima kept his true personality in secrecy under the pretense of mourning the loss of his son. Kazuya. The plot is, they are kidnapping teenagers with super powers with high-tech armor after grabbing samples of AMAZO's parts after the events of Season 1: the episode Schooled after the Team stops Amazo. What is Heihachi and Lex's plan? And what will they do next? Find out in the next chapter. Sorry for the short prologue. Also the characters of Tekken and Young Justice are not mine. But the property of Namco and DC Comics.

As for Emerald Sustrai, I am adding RWBY Characters, but not the Remnant versions, just the Earth-16 versions of them.
