Alright. Here we go. This is the last chapter of the final battle with Chase.

I chose this chapter title because this is what I promised in Worlds Collide, Heroes Clash. The Defenders are reassembling. Well, except for Jesse, as she's still back in Earth-2. But all the rest of the Defenders are gonna be making appearances here on Lian Yu, and they'll all have roles to play in this final battle.

Let's get to it.

Chapter 24- The Defenders Reassemble

Bucky and Slade race through the halls of the monastery, knowing they have to find Laurel and the others before Chase finds them.

After a minute, they race around a corner, and they see Rene, Diggle, Quentin, and Laurel all chained to a ring on the ground.

"Bucky!" Laurel cries in relief. However, Quentin and Diggle are more concerned with Bucky's partner.

"Slade!" Diggle growls.

"Easy, guys. The Mirakuru wore off. He's on our side now," Bucky explains calmly.

Slade looks at Diggle and Quentin and says, "I know I've done terrible things, and for that, I am sorry. But like Barnes said, I'm on your side now." Both Diggle and Quentin look hesitant to believe him, but know they don't really have a choice now.

"Alright. Let's get you out of here. Felicity handed me this before we sent them off. SOmething she and Curtis were working on," Bucky says as he pulls out the sound modulators Felicity had at his surprise party and hands them to Laurel. "They'll bypass the sonic dampener and focus your cry," he explains.

"Yes! Remind me to give them both hugs!" Laurel says with a big grin as she puts the modulators around her neck. She gives everybody a quick look and says, "Cover your ears."

Everybody quickly covers their ears, and Laurel unleashes her cry, easily shattering the chains binding her and the others to the ground.

"Alright. We got to move. Barry's getting everyone else to Chase's plane, and Kid Flash is looking for Oliver's son," Bucky explains.

"Wait. Chase took William?" Diggle asks in shock.

"Yeah. And for now, we need to leave finding him to Kid Flash. We need to take care of Chase and the rest of his lieutenants," Bucky says. Diggle nods.

"Alright. Let's move," Bucky says, and he leads them out of the room.

"We find Chase, we hopefully find William," Bucky says.

"Yeah, not so sure about that, Hoss," Rene says as up ahead of them, Chase stalks into the room, drawing his sword from his back. Following behind him are Dinah, Carrie Cutter, China White, Viper, and the rest of Viper's men.

Chase looks smugly at Bucky and says, "Hey, Bucky. Welcome to Purgatory."

The two sides stare each other down for several moments. Then, Bucky demands fiercely, "Where is William Clayton?"

"Ah, your buddy Oliver put you up to this. Tell me, where is he? If he's the devoted father I think he is, why isn't he here?" Chase asks.

"That's not your concern. But to satisfy your curiosity, he thinks I am more than capable of stopping you. And he's right. You have no idea what I've done in my past, and what I'm capable of. So try as you might. You're never gonna get to Oliver Queen again," Bucky says confidently.

Chase shakes his head a little and says, "Never say never."

Right then, the window smashes as an arrow flies down and lands behind Viper's men, who are gathered behind Chase, Dinah, Viper, Cutter, and White. A second later, it explodes, knocking them all off their feet and killing a few of Viper's men from the shrapnel.

Bucky and everyone on Team Arrow looks up to the window, right as Clint, dressed in his new Hawkeye uniform, swings through the window. He lands on one knee, springs to his feet, twirls his bow in hand, then smiles. "Let's get this started," he says before rushing right towards Viper. Two of Viper's men try to stop him, but he easily knocks them out of the way and leaps right at Viper. Viper jumps back to give herself a second to recover herself, then draws two small batons strapped to her legs and strikes back at Clint. Clint strikes at her with his bow, and the two begin fighting fiercely. At the same time, Vincent and Roy race into the room, weapons at the ready.

With the distraction caused by Clint's explosive arrow, the rest of the team attacks. Slade, Rene, Vincent, and Quentin all hurry to attack Viper's men. Laurel races forward and attacks Dinah, while Diggle lunges for China White. FInally, Roy and Carrie Cutter start shooting at each other as they race to attack each other at close range.

Meanwhile, Chase gets back to his feet, and glares at Bucky. "You may have friends, Bucky. But you can't stop me. I'll kill you here and now, and then I will find Queen and break him!" Chase shouts, the look of insanity in his eyes growing ever greater.

"I don't think so," Bucky says firmly, and he rushes at Chase. Chase swings with his sword, but Bucky blocks it with his cybernetic arm. The two begin exchanging blows almost faster than the others can follow. Not that they're paying much attention.

Roy and Cutter keep exchanging blows, alternating between using their bows and their fists. After a minute, they end up in a standstill, both bows pressing against the other.

"I remember you. The Arrow's old sidekick. I took out you too easily last time I saw you," Cutter says.

"I know. And I've gotten much better since then," Roy says in his disguised voice. He then lifts his foot up and kicks Cutter in the knee. Cutter stumbles, and Roy uses the chance to force her bow out of her hand, then jumping up and kicking her in the head, knocking her out.

Meanwhile, in a hall off the main chamber, Laurel and DInah are fighting tooth and nail with each other. Laurel finds herself extremely grateful that Bucky trained her so much in hand to hand. Otherwise, she may not be able to stand against Dinah.

The two keep exchanging blows until Laurel finally manages to get in a good hit and knock DInah down. Dinah looks up in anger, and Laurel knows what's coming. She opens her mouth at the same time Dinah does, and the two unleash their cries at the same time The collision from the two cries sends both of them flying back. Laurel ends up getting knocked into some shelves, while Dinah ends up crashing into some steps.

Laurel groans as she tries to recover her senses. Dinah, however, struggles to her feet quickly and stalks towards Laurel. "You thought you could beat me? You will never measure up to me! I am better than you will ever be!" Dinah shouts. Suddenly, before she can unleash her cry again, something grabs her wrist. She turns to her right, and sees Vincent standing there, still with his mask on.

She glares at him and his about to unleash her cry when he shouts, "Enough, Dinah!" And with that, he yanks his mask off, revealing his face to her.

Dinah's eyes widen, stunned into silence. It takes a moment before she's able to splutter, "Vinnie? Is that you?"

"Yes. It is, Dinah. I survived the bullet, thanks to that particle accelerator explosion. And frankly, I am disappointed in you. I can understand wanting revenge for me and killing Sonus. But singing on with someone like Chase?! Dinah, what has happened to you?! You're not the woman I loved!" Vincent says angrily.

Dinah looks like she doesn't know what to say. After a few moments, Vincent sighs and says, "We'll talk about this later." He then grabs a syringe with a sedative in it and jabs it into her arm. In seconds, Dinah is unconscious.

Vincent turns towards Laurel, then walks over to her and helps her up. "Thanks," laurel says simply. She then looks him over and asks, "What took you so long to get here?"

"Digger Harkness. He and two of Viper's men held me and Roy Harper up. Harper took care of Viper's goons, and I killed Harkness," Vincent says simply. Laurel just nods in response before they turn and run back into the main room.

As they do, Diggle is still fighting China White. He manages to dodge a slash from one of White's knives, then grabs her wrist to stop her from doing it again.

"You've gotten in my way too many times, John Diggle. I'm going to be so happy to finally put you in a grave," White says.

"And you've threatened me and my loved ones a time too many," Diggle says.

White smiles before getting in a cheap shot and knocking him onto his back. She raises her knife and prepares to strike. Until a blade sprouts from her chest. She gasps, and looks down at the blade. Then, it's withdrawn, and White collapses to the ground, lifeless. And Diggle sees Slade standing behind her, his sword bloodied.

Diggle just looks at him for a few moments. Finally, he says, "Thanks, Slade."

Slade nods as he extends his hand. Diggle accepts it and lets Slade help him back to his feet.

As he does, across the room, Clint gets under Viper's guard and manages to knock one of her batons out of her hand. He then blocks her other baton with his bow. For a moment, they struggle against each other. Then, Clint smirks, and says, "Nighty-night, snake." He then draws a sedative tipped arrow out of his quiver and stabs it into VIper's leg. Viper cries out in pain, but the sedative overwhelms her in seconds, and she collapses.

As Clint stands triumphantly over Viper, the rest of the team finishes off the rest of Viper's men, leaving just Bucky and Chase still fighting. Everyone stands and watches them for a few moments before Bucky finally manages to get under Chase's guard for a split second and delivers a punch from his cybernetic arm powerful enough to not only knock Chase flying back into the wall, but also break two of his ribs.

Bucky stalks over to Chase, his face a mask of no emotion. "I'm gonna ask you again, Chase. Where is William Clayton?" he demands.

Chase chuckles a little bit. Then, he says mockingly, "I knew we'd come to this. William is dead, Barnes."

Everything goes quiet. Everyone starts at Chase, not wanting to accept that.

Bucky, however, glares at Chase. "If that is true, then you will pay for it" He reaches for his pistol, but right then, Barry races into the room.

"STOP!" he yells as he sees Bucky pulling out his pistol. Bucky stops, and everyone turns to Barry.

"Barry? What is it?" Bucky demands.

"Chase has wired the entire island with explosives. And Felicity just figured out they're linked to a dead man's switch. He wants you to kill him so the island blows up and kills us all," Barry explains.

A chill runs down Bucky's spine. A rustling behind him quickly catches his attention. He turns and sees Chase has regained his feet. He reaches into his jacket, and Bucky realizes what he's doing.

"Get down!" he shouts as Chase throws down the sphere he just drew out of his pocket. The sphere explodes in a blinding flash and a cloud of smoke, temporarily disorienting everybody.

Once the smoke clears, everybody looks up to see that Chase is gone. Right then, Wally races into the room too.

"I've searched just about everywhere. I haven't been able to find him," he says.

"We've got bigger problems. Barry, Wally, I need you to get everybody out of here. Unfortunately, that includes our unconscious enemies. Get them to the plane, and make sure you get them all off the island," Bucky orders.

"What about you, Bucky?" Clint asks.

"I'm going after him. He might lead me to WIlliam. But one way or another, Adrian Chase is not getting off this island," he says before he turns to race away.

"Wait!" Laurel cries out. Bucky turns back to face Laurel, and has just enough time to register her running up to him before she grabs his face, pulls him closer, and kisses him.

For a moment, he stands there stunned. When she pulls back, he looks at her and asks, "What was that for?"

With a hint of a tear in her eye, Laurel says softly, "Just in case something happens, I wanted you to know how I feel."

Bucky looks back at her silently for a moment, then smiles comfortingly. "I'll be okay. And we'll talk about this when we're off the island," he says. Then, he turns and runs out of the monastery, determined to find Chase.

Barry and Wally begin racing everybody to the plane one by one. At the same time, Bucky races through the woods. Thankfully, in his haste, Chase had left tracks for Bucky to follow. At the same time, Bucky knows that with Chase, he's probably left the tracks on purpose, luring Bucky after him.

It doesn't take him too long before he reaches the coastline, and finds himself next to a set of docks. And, with fury, he sees Chase standing on the aft section of a small motorboat. Chase looks back at him, smiling smugly, before he revs up the engine, and the boat begins to pull away from the dock.

Bucky races along the shore, leaping onto one of the docks to get closer. FInally, he's close enough to the boat, and leaps from the dock onto the front of the boat. He clambers over the roof covering the interior of the boat and leaping down on Chase, punching him in the head and knocking him down.

Bucky spins around, grabs Chase by the throat, lifts him into the air, and demands, "Where is William Clayton?!"

Chase just chuckles, so Bucky throws him to the ground. He ends up hitting the controls, and accidently pulling down the throttle, cutting the engine and slowing the boat to a stop.

(The plane)

Barry and Wally speed up, bringing Vincent and Dinah with them.

"Is that the last of them?" Thea asks.

"Yeah," Barry says. Everybody is there, including Viper, Cutter, and Evelyn, the three of whom are all tied up.

"Alright. Let's go!" Malcolm says, very impatient to get off the island.

"Actually, we're not going anywhere," Slade calls out. Everyone turns to him, as he holds a piece of machinery.

"I found this 10 feet from one of the wings. It's a crucial part of the plane's hydraulic systems. Without this, we'll never be able to maintain control of the plane," Slade says.

A chill runs down most everybody's spine. Samantha, now terrified for William, says, "I have to go find William!"

"No! You're staying with us. Bucky will find him. We need to get off the island," Roy says firmly.

"Somebody has to contact Bucky and let him know the situation," Barry says. Laurel reaches for a comms unit.

(The boat)

Bucky pins Chase to the ground, glaring down at him with absolute fury. "Where is William?!" he bellows before punching him several times. He then lifts Chase into the air again before throwing him into the ground again.

Suddenly, his comms crackle to life. "Bucky? Do you copy?" Laurel's voice calls over his earpiece.

"Yes, I copy. What is it?" Bucky demands.

"Chase sabotaged the plane. We can't use it," Laurel explains.

"There's an ARGUS supply boat docked on the eastern shore. Slade knows where it is, and Barry and Wally can get you all there," Bucky says.

"They'll never make it in time," Chase's voice says behind him. Bucky turns around, just in time to see Chase open the door leading below and pulling William out, putting him in a headlock.

Bucky growls and yanks one of his pistols out of its holster. "Let the kid go!" he bellows.

"Oh, don't posture. You won't shoot me when I've got him like this. You care too much about protecting innocents. Or do you?" Chase says with a smirk on his face. He pauses for a moment, then says, "If you kill me, everyone you care about that's on that island dies. But if you don't kill me, I kill him. And you have that death on your conscience, and you get to tell Oliver his son is dead."

Bucky glares at Chase with pure hate. "You SOB," he growls.

"William or everyone else?" Chase asks.

Bucky continues to glare at him for a few more moments. Then, he slowly lowers his pistol. Chase smirks triumphantly, not noticing Bucky's free hand slowly getting closer to his thigh. Then, right as his hand holding the pistol drops to his side, Bucky uses his free hand to yank another pistol from its holster, and in a movement so fast Chase couldn't hope to react, aims it at Chase and fires. The round hits Chase right in the knee and blowing out his kneecap and tendons. Chase collapses, unable to support himself with one leg, and giving Bucky the opportunity to pull William out of his grasp.

Bucky puts his hands on William's shoulders and bends down, suddenly anxious to make sure the boy is okay. "Hey, are you okay? Are you alright, William?" he asks. William nods, still very shaken.

Bucky gives him a hug, saying softly, "Don't worry, William. You're safe now. He's not gonna hurt you anymore. I'm gonna get you back to your mom."

He then slowly lets William go and says, "Don't look, William." WIlliam nods and tries not to look at Chase as Bucky steps away from him.

Bucky steps towards Chase as Chase is getting into a sitting position, then punches him in the face with a growl of "You SOB!" He then grabs Chase and puts him in a headlock.

Chase struggles against Bucky, but it is painfully clear which of them is stronger.

After a minute, Bucky's comms crackle to life again. "Bucky, it's Barry. We got everyone to the boat, and we cast off. We're clear," Barry says.

"Understood," Bucky replies. Then, he tightens his hold on Chase.

Bucky leans down so his mouth is next to Chase's ear. "Oliver Queen is still missing. That was me that apprehended you as the Green Arrow. Just wanted you to know," he says.

He pauses for a second, then says, "I know you're trying to prove to Oliver Queen that he's a killer. And I know, if he was here, he wouldn't kill you. But, I already know I'm a killer. You don't have to prove that to me. So, I have no qualms about doing this." He adjusts his grip on Chase, then says, "Have a nice trip to hell, Chase." And with that, and a powerful twist of his arms, he snaps Chase's neck.

A second later, he lets go and stands up, letting Chase's body fall to the ground. And right then, the explosions begin. Bomb after bomb detonates as Lian Yu begins to be eveloped in flames.

"Mom!" William calls out. Bucky steps up and puts a comforting hand on his shoulder.

"Don't worry, buddy. The Flash showed up and got your mom everybody else off the island," Bucky says.

William looks up at Bucky. "He did?" he asks hopefully.

"Yeah. He did. Everyone's going to be fine," Bucky says.

He glances back at Chase's body, and feels a grim satisfaction flow through him. At last, Prometheus has been defeated.

And with that, the final battle comes to an end. I hope you enjoyed how I did this. I sure enjoyed writing it. This is actually my longest chapter so far.

I hope you like I brought the Defenders back. Sure, Wally didn't do too much, but he still helped. Plus, I thought it would be nice to bring them all back (except Jesse), and to have Clint fight Viper.

I decided to kill off Harkness and White because I have no further plans for them. I'm planning to use Cutter as a member of the Suicide Squad in the future, and Viper will play a role in the future of this series at some point.

Now, I'm sure you're wondering why I had Bucky kill Chase. I found it simple. Bucky didn't have the same problem Oliver did. He wasn't the one being targeted by Prometheus for being a killer, and I think he would've had less of a problem killing Chase than Oliver did. Plus, I had no reason for Chase to stick around.

As for Dinah and Vincent. I had always planned for Vincent to stop Dinah. In part because I want to use her in a hero capacity in the future, and Vincent turning her back was one way I liked. Now, after this story, we won't see them again for a while. But, they will be returning at some point. When, I'm not sure. Guess we'll have to wait and find out.

Next chapter will be the final chapter, and it will wrap up most loose ends and bring this story to a close.

Well, until the next chapter, please review and tell me what you thought of this one, and stay tuned!
