Jason Hunter: Yes, Sam has, and I agree, Walker is US Agent now.

Guest: Yes, it was an amazing episode for sure, and Sam with the shield is awesome. Yes, Walker is stripped finally, becoming US Agent instead. And now my sympathy for the guy has reduced by a lot because last night I'd a nightmare where he chased me to try to kill me, though I woke up before the shield could hit me *sighs in relief

Chapter 8- I am inevitable

Tony had passed out due to the exhaustion again as everyone mourned for Coulson.

"Where are you going?" Steve asked as Carol was walking off.

"To kill Thanos." Carol explained.

"Hey. You know, we usually work as a team here and between you and I, morale's a little fragile." Natasha intervened.

"We realize up there is more your territory but this is our fight too." Steve pointed out.

"You even know where he is?" Rhodey asked.

"I know people who might." Carol said.

"That's all you have?" Matt asked incredulously.

"No wonder you're not so marvelous." Cordelia quipped as Carol glared again.

"Don't bother." Nebula then said upon entering. "I can tell you where Thanos is."

Rocket turned on the hologram of Earth. "When Thanos snapped his fingers, Earth became ground zero for a power surge of ridiculously cosmic proportions."

They saw a pulse of energy coming throughout the Earth and possibly the entire Milky Way. "No one's ever seen anything like it. Until two days ago… on this planet."

The hologram showed a distant planet marked 0259-S, where the same power surge appeared.

"Thanos is there." Nebula realized.

"He used the Stones again." Natasha deduced.

"Hey, hey, hey, we'd be going in shorthanded, you know?" Bruce argued.

Rhodey spoke up. "Look, he's still got the Stones, so…"

"So let's get them. Use them to bring everyone back." Carol proposed.

"Just like that?" Bruce scoffed.

"Yeah. Just like that." Steve nodded.

"Sounds good to me", Angel shrugged.

"Even if there's a small chance that we can undo this… I mean, we owe it to everyone, who's not in this room to try." Natasha said.

"Yeah." Buffy agreed. "We have to do this for them."

"If we do this, how do we know it's gonna end any differently than it did before?" Bruce pointed out.

"Because before, you didn't have me." Carol said.

"Hey, new girl? Everybody in this room is about that superhero life. And if you don't my asking, where the hell have you been all this time?" Rhodes demanded as he turned to Carol.

"There are a lot of other planets in the universe and unfortunately, they didn't have you, guys." Carol said.

"Bullshit!" Logan snapped, forcing Carol to be silent.

"My father would have known if someone like you were interfering in his business." Nebula sneered.

"Why haven't the Guardians met you? Or Heimdall would have." Thor glared.

"Where were you when Ronan and then Thanos attacked Xandar?!" Rocket snarled.

"Who's this Ronan guy and when did and Thanos attack me?" Xander now demanded.

"Not you, dumbass, there's a planet called Xandar!" Rocket said to him.

"There's a planet named after me?" Xander wondered.

"It's spelled X-A-N-D-A-R." Thor told him.

"Ah, right." Xander said lamely with a nod.

"Clearly, whatever you were doing, you weren't doing it properly", Clint snarled at Carol.

Carol's eyes were now wide as she looked at Rocket before backing down against them all, knowing that accusations against her were very true. Guilt and shame was now flashing in her eyes as she had not done her job properly for sure.

Carol looked at them all with guilt in her eyes and realized she had crossed a line with her arrogance this time.

"I-I knew about Thanos." Carol said as she looked up at them all. "But I was too afraid of him. So I continued trying to find a home for the Skrulls."

She then looked at them apologetically. "I'm sorry for my behavior. I crossed a line with it."

"I think am ready to do this now." Matt said, holding out his clubs as he cracked his neck.

Thor got up and walked up Matt, sizing him up as Matt sensed him nearby. He then held out his hand as Matt tilted his head a little to listen a disturbance in the air.

Stormbreaker flew to Thor's hand right next to Matt, who tilted his head again as Thor said. "I like this one."

"Let's go get this son of a bitch." Steve ordered.

Later

Steve, Natasha, Logan, Buffy, Angel, Matt, Clint, Bruce, Rhodes, Nebula and Thor were in the Benatar as they and Carol flew towards The Garden.

"Okay. Who here hasn't been to space?" Rocket asked.

Steve, Natasha, Logan, Buffy, Angel, Matt, Clint and Rhodes raised their hands.

"What?" Rhodes wondered as Carol chuckled.

"You better not throw up on my ship." Rocket said to them all.

"I am feeling….strange." Matt said.

"Well, your senses." Angel pointed out and Matt nodded.

"Approaching jump in 3.. 2.. 1." Nebula said and pulled a lever as the speed increased and soon, they passed a jump point.

As they reached their destination, the lower portion opened up and Carol flew out.

"I'll head down for recon." She said and flew down.

Steve took out his old compass and looked at the picture of Peggy on it

"This is gonna work, Steve." Natasha assured him.

"I know it will." Steve said optimistically. "Because I don't know what I'm gonna do, if it doesn't."

"Me neither." Buffy muttered to herself.

Carol flew back up. "No satellites. No ships. No armies. No ground defenses of any kind. It's just him."

"And that's enough." Nebula pointed out.

Thanos was walking down the Garden and harvesting crops and he entered his hut and prepared food, when suddenly a portal opened in front of him and Willow was there.

"You…." He said when she suddenly fired a powerful blast of magic at him, enhanced by the little power she'd absorbed from the Gauntlet as he rolled away, growling, and then a beam from outside hit him as he put the Gauntlet in the way to protect himself when a burst of energy from Willow covered him, making him scream while Carol leapt inside and tackled him to the ground.

"Your soul seems….pleased." Willow snarled in rage as she pressed her fist and purple energy covered Thanos, making him scream in pain while Bruce and Rhodes arrived, shocked at what Willow was doing. Then Thor burst in and chopped off Thanos's hand with Stormbreaker as he screamed even louder in pain.

Steve, Natasha, Logan, Buffy, Angel (holding a blanket over himself), Matt, Clint and Rocket then walked in.

"Will?" Buffy asked in shock. "What are you doing here?"

"Same thing you are", Willow snarled as she pressed her hand tighter and Thanos screamed louder. "You killed her, you bastard!"

"Will, stop!" Buffy said.

Matt used his senses and said. "I don't think these Stones are here."

"What makes you so sure, bub?" Logan asked him.

Rocket turned the chopped off hand around to see the Stones were missing from the Gauntlet.

"Where are they?" Steve asked Thanos who groaned.

Willow hit him with another powerful burst as he screamed while all looked at her in concern. "Answer the question, you filth!"

"The Universe required correction. After that, the Stones served no purpose beyond temptation." Thanos explained to them.

"You murdered trillions!" Bruce yelled, outraged as he shoved Thanos, knocking him down.

"You should be grateful…" Thanos grunted when Willow hit his face with a powerful burst, making him spit out blood.

"You bastard", Willow sneered.

"Hey, stop", Angel said as he tried to hold her back gently but she pushed him away.

"Where are the Stones?" Natasha demanded.

"Gone. Reduced to atoms." Thanos said.

"You used them two days ago!" Bruce snapped.

"I used the Stones to destroy the Stones." Thanos revealed as they saw half of his body burned. "It nearly killed me. But the work is done. It always will be. I am… inevitable."

Everyone stared in disbelief as Willow was growling.

"Will, control yourself", Buffy said gently, trying to hold her back.

"We have to tear this place apart. He has to be lying!" Rhodey said desperately.

"My father is many things." Nebula said. "A liar is not one of them."

"I could smell it if he lied", Logan sneered, his claws popping out as he watched, enraged.

Clint now fell to his knees, looking broken as Natasha put a hand on his shoulder.

Thanos turned to Nebula gratefully, wondering if he should have treated her better. "Ah. Thank you, daughter. Perhaps I treated you too harshly…"

"Bored now", Willow then said with a sadistic smirk.

That moment, Thor roared as he swung his axe while Willow pressed her fist and Thanos' head fell off his neck at the same second his entire body was skinned by Willow's 'Power Stone' magic, the magically peeled off skin now falling to the ground as his head rolled down on the floor and skinless body toppled a moment later, the blood spattering everywhere.

"What?" Bruce said in shock.

"What did you two do?" Rocket whispered, realizing that all hope was gone.

"I went for the head." Thor said, sounding hollow and defeated as he started walking away.

"This…is…." Willow screamed as she let out a powerful burst of magic, sending all but Thor flying back as he planted his feet to the ground, unmoving.

"Willow, don't do this!" Buffy said as she staggered back up with the rest.

"I understand you've lost everything", Steve said as he held out his hand in sympathy. "I really do-"

"You could never", Willow snarled.

"Willow, this isn't you!" Angel said.

"Tara wouldn't want you to", Buffy told her and now Willow glared. "I know you, Willow."

"Let me tell you something about Willow. She's a loser. Always has been. She got picked on through junior high, high school, right up until college. With her stupid mousy ways. And now?" She laughed bitterly, her brokenness clear for everyone to hear and see. "Willow is too much into magic without thinking it through. The only thing Willow was ever good for...the only thing I ever had going for me were those moments...just moments...where Tara would look at me and I was wonderful. And that will never happen again."

Everyone could feel their hearts break at the pain in her voice as Thor said gently, holding out his hand. "I know what it is like to lose everything, trust me I do, but what you are doing now, young witch, it is not going to help."

"SHUT UP!" Willow screamed as she fired another powerful burst but Thor deflected in time with Stormbreaker.

As the rest moved to her, she sent them all flying back with her power. Thor tried to hit her with a weak lightning blast but she escaped into a portal before he could.

"Where did she go?" Steve asked as he looked around.

"I tried to sense what was on the other side of the portal", Matt informed him. "She is on Earth now."

"We need to get back right now", Buffy said urgently.

"How did she get this powerful this quickly?" Natasha then asked.

"The bursts of power she used on Thanos, it resembled that of the Power Stone", Thor noted.

"And she said to him that she could feel his soul was pleased", Carol remembered.

"The portal looks like what you would get from the Space Stone", Logan added.

"The Stones", Angel realized. "She has some of their power inside somehow."

"Can that work?" Rocket asked hopefully as Clint now looked up, slightly hopeful.

"We don't know, but we need to talk her down first", Bruce pointed out.

"Yeah, let's go back to Earth", Steve agreed with a nod.

Few hours later, Avengers Compound

Everyone was back as Buffy walked to where Xander and Dawn, Dawn now up.

"What happened?" Dawn asked Buffy desperately.

"Guys", Buffy said, gulping, wondering how to do this conversation. "It's Willow-"

"Where would she be?" Steve wondered.

"We can try to track her", Natasha said as she typed on her computer.

"Can you lot track magic?" Cordelia asked.

"No, but the Stones' power, we might", Fitz told them as he and Jemma helped.

"We just have to lock onto it", Jemma said.

"You don't need to."

Matt sighed, 'seeing' a yellow circle with his sight again as Wong stepped out of it.

"Wong", Bruce greeted him.

"Who are you?" Logan asked. "Wait, you can open a portal like the Strange guy."

"You're a Mystic", Angel realized.

"I know where she is, she has grown powerful", Wong told them. "And unstable."

"The power she has", Clint asked desperately. "Can it be used to undo this?"

"No", Wong shook his head as all now felt their hearts had been hit by a hammer, Matt falling to his knees as he punched the ground angrily. "She absorbed the bare minimum of the power of 3 Stones- Power, Space and Soul. She can now use some energy resembling the Power Stone, open portals, and sense everyone's souls, and feel them, but that is all she can do."

Clint immediately turned around and stormed off as Natasha walked after him. "Clint, hey! Clint!"

Clint turned around to look at her, looking completely broken, and then turning around, walked off, leaving Natasha behind and ignoring her shouting his name.

"What is she doing now?" Gunn then asked Wong with a gulp.

"She is trying to destroy the world", Wong revealed to their horror.

Cordelia started. "All right, I get it, she's unstable, but she'd never-"

"She can feel the pain of all the souls that is left, and they grieve and they mourn, and she cannot take it", Wong explained. "She wants it all to just end, like her own pain."

"We have to stop her", Bobbi said as all looked at her. "Half of the world is gone, but we can't let her do this."

"This will just make it worse", Mack agreed.

"I can feel what she's going through", Thor said as Natasha came back in. "What should we do, Cap?"

Steve was about to say something when Xander's voice said. "I'll talk to her."

They turned to see Xander standing there with Buffy and Dawn nearby.

"What?" Rhodes asked. "Are you crazy, she will-"

"Out of everyone in this room, I have known her the longest, if she'll listen to anyone, it's me", Xander said.

"Guys, give him a chance, please", Buffy requested.

"He can bring her back", Dawn nodded, not wanting to lose Willow as well after having lost Peter, Tara, Giles and Anya, just about 2 months after mom.

"What do you think, Cap?" Bruce asked, turning to him.

"We'll follow your lead", Logan said in agreement.

"Just say the word", Wesley nodded.

Steve looked at them and said. "Xander will go and try to talk to her, but we must stay hidden nearby and make sure she doesn't see us."

He turned to Xander and said. "If you fail, then I am sorry, but we must do what needs to be done."

"I won't fail, I promise", Xander assured.

"I'll take you all there", Wong told them.

Willow was attempting to channel the power of the Earth and focus it on Proserpexa's effigy to burn the world to a cinder.

Green magic was flowing from Willow towards the statue. Wind swirled around them, filled with dirt and debris, etc. Also some lightning, nothing compared to Thor though.

The statue glowed bright yellow-white. Suddenly the stream of magic was interrupted and the glowing subsided, as Xander appeared in front of the statue. Willow looked surprised.

"Hey, black-eyed girl. Whatcha doin'?" Xander asked, both horrified and heartbroken to see her like this.

Willow snarled. "Get out of here."

Xander quipped. "Ah, no. You're not the only one with powers, you know. You may be a hopped-up uber-witch, but ... this carpenter can dry-wall you into the next century."

Willow again snarled. "I'm not joking, Xander. Get out of my way. Now."

Willow sent a bolt of magic at Xander. It lifted him off his feet and threw him to the ground at the base of the statue.

Dawn gasped from where she was and tried to move but Buffy stopped her. "Wait."

"Just let him talk to her, as long as he is up and the world isn't gone, she can be brought back", Steve told the rest.

Lightning continued to flash around the statue. The green magic began flowing from Willow again, toward the statue with the Earth rumbling, winds swirling, etc.

Xander sat up at the base of the temple, holding his ribs. He staggered to his feet and blocked the flow of magic again. The magic stopped flowing. Willow glared at him. "You can't stop this."

Xander nodded. "Yeah, I get that. It's just, where else am I gonna go? You've been my best friend my whole life. World gonna end ... where else would I want to be?"

Willow sounded scornful. "Is this the master plan? You're going to stop me by telling me you love me?

Xander quipped. "Well, I was going to walk you off a cliff and hand you an anvil, but ... it seemed kinda cartoony."

Willow scoffed. "Still making jokes."

Xander told her. "I'm not joking. I know you're in pain. I know the pain you're in, I lost Anya too. And I know you're about to do something apocalyptically", he glanced back at the statue, "evil and stupid, and hey." He spread out his arms. "I still want to hang. You're Willow."

Willow was angry. "Don't call me that."

Xander then reminded her. "First day of kindergarten. You cried because you broke the yellow crayon, and you were too afraid to tell anyone. You've come pretty far, ending the world, not a terrific notion. But the thing is? Yeah. I love you. I loved crayon-breaky Willow and I love ... scary veiny Willow. So if I'm going out, it's here. If you wanna kill the world? Well, then start with me. I've earned that."

Willow sounded upset. "You think I won't?"

Xander assured her. "It doesn't matter. I'll still love you."

"Shut up." Willow angrily gestured with her hand. No magic bolts of light, but Xander's head jerked to the side as if he'd been hit. Three parallel cuts appeared on his cheek, bloody as if scratched.

He put his hand up to them, looking at his fingers.

Willow watched, panting and looking a bit nervous. Xander looked back up at her. "I love you."

Willow made another slashing gesture. Xander doubled over and fell to his knees. Panting, he got up again, and now his shirt is ripped open over the heart, more scratches visible on his chest.

He panted and grimaced from the pain but faced Willow again. "I ... love y-"

"Shut up!"

Now she did throw a blast of magic at him, and he staggered backward but didn't fall down. Willow still held her hand out, a little bit of magic crackling around it but not as much as she had expected.

She looked surprised and anxious. Xander moved slowly towards her. "I love you, Willow."

"Stop!"

She sent another magic blast, but it was weak and barely hurt Xander at all. He continued walking toward her.

Willow continued holding out her hand and making the magic gesture, but nothing happened. She started to get teary.

"I love you."

"Stop."

Willow started to cry and, as Xander got right up to her, she started hitting him with her fists in anger. Xander just stood there and took it.

After a moment she stopped hitting and started to cry for real. She fell to her knees and Xander kneeled with her, putting his arms around her and held her while she sobbed.

"I love you."

As Willow continued to cry in Xander's arms, the veins faded away from her face and her hair returned to its usual red.

Buffy and Dawn now ran to Willow too as Steve said in relief. "He did it."

"Yeah", Angel nodded, reminded of himself and Faith. "He saved her."

"What happens to her now?" Natasha asked.

"I will take her with me to the New York Sanctum", Wong said to them. "She drew power from the Hellmouth before, it was corrupting, and now the power of the Infinity Stones, even the most minimum of it, is inside of her, she has to learn to control it. I will teach her to use sources of magic that are not corruptive, and they will purify her."

"I believe that is a wise choice", Wesley agreed with a nod.

One day later, Sunnydale, Parker house

May was working in the kitchen, still worried for Peter, Dawn and the rest, not having heard from them ever since the dusting, when there was a knock on the door.

Dropping everything, she rushed to the door and opened it. "Pet-"

But it wasn't Peter. It was Buffy and Dawn, both looking tearful.

Their expressions were enough to let her know what had happened.

"No", she broke down falling to her knees. "No, my boy-"

She burst into tears as Buffy and Dawn both hugged her, attempting to comfort the poor woman while they cried themselves over all their losses.

New York, Hell's Kitchen, Clinton Church

Matt stumbled into the Church, the brokenness on his face showing as he felt to his knees in front of the altar, dropping his cane and glasses and sobbing at all of the losses he had just experienced- Maggie, Foggy, Karen, Marci, Foggy's family, Danny and Colleen.

God was punishing him for what he was- a Demon!

His grief and rage getting to him, he let out a loud roar.

"EEEEEAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAARRRRGGGGGGHHHHHHHHH!"

A shadow moved across Spike's face.

"You have endured the required trials."

Spike nodded. "Bloody right I have."

Slowly, painfully, Spike rolled onto his side and pushed himself up onto his knees. His face was swollen and bruised, with more bruising and injuries on his chest and arms. "So you'll give me what I want. Make me what I was. So Buffy can get what she deserves."

The Demon's eyes were green and glowing. "Very well."

Spike watched the demon nervously. "We will return..."

The demon's hand reached out toward Spike's chest. "...your soul."

The hand touched Spike's chest and it glowed fiery yellow-orange. Spike's eyes glowed the same color. He threw back his head and screamed.

New York, Hell's Kitchen

Days had become weeks, and Matt was still in his house, not going out again, just sitting and brooding, almost everything he cared about gone now.

His phone beeped as he got a voice message from Cordelia- "Matt, it's Cordy, but you knew that already, of course. Just, uhh, just call me back, okay?"

Then there was another from Angel- "Look, buddy, if you need anyone, I'm here for you."

That was followed by Wesley- "Matthew, I hope you are taking care of yourself. At times like this, that's the only thing you can do, I am sorry."

And then there was Gunn too- "Hey man, look, I don't know what to say, I'm sorry, just, don't go around behaving like me, okay?"

Matt just closed his blind eyes, trying to block it all out.

Then he heard something. A little girl! Screaming for her father! There were sounds of beating as the bloodied father was dragged somewhere.

A little girl was crying in a corner, watching as three men dragged her beaten and bloodied father into a van. She ran to them and tried to pull one back but he tossed her to the ground, making her head bleed.

They put the father in the van and turned around, only to see Daredevil standing there!

Before anyone could react, Daredevil punched the first one hard, sending him down as he grabbed the other, and leaping, kicked the third away.

He then brought the face of the one he'd grabbed down on his knee, breaking his nose, and kneed his face repeatedly till it was bloodied.

The one he'd first punched grabbed him from behind as Daredevil elbowed him twice, making him let go, then grabbing him, flipped him to the ground, and stomped on his chest hard, breaking his ribs as he coughed.

The third ran at him as Matt grabbed the one whose face he'd kneed and tossed him to that one, sending both falling. And then he grabbed the third one and slammed his head on the ground multiple times, finally taking him out too as the back of his head bled.

"Th-thank you", the girl said to him.

"Call 911", he immediately told her.

Later

The girl clutched her unconscious father as paramedics took him into the ambulance, and the 3 beaten up thugs were put into a police van.

Daredevil was perched above on a building as he realized that even with half of the world gone, darkness existed, and he was needed to fight it, fight for his city.

Next night

A group of 5 Demons walked to the Metro-General Hospital, deciding to raid it, since they all believed Daredevil was dusted, so now nothing stood in the way of Demons coming to New York City again.

Just as they made it to the door, one of them was hit from behind and fell down, and they turned to see Daredevil standing there, suited up, putting his club back inside.

They gulped as Daredevil grabbed the one in the front, clearly the leader, by the throat. "You're going to deliver a message for me. Tell them, tell them all, if I even smell a Demon in my city, I'll show them Hell."

And with that, ends Part 1 of this story.

Now I won't be dividing IW and Endgame into 2 parts, I'm gonna keep it as one story, because movies have time limits, fanfics don't have that constraint.

Willow's speech of 'Tara would look at me and I was wonderful' always breaks my heart.

So now since Giles is gone, instead of the Devon Coven, Wong will take her in

Spike's soul is back too.

And Matt has realized he can't give up, but he has lost hope now.

Now I will be doing a leap, but not a 5 year leap like the MCU. I think that was only done so that Morgan could be 5 years old, and she and Tony would have sweet moments before he sacrificed himself at the end.

But I don't need to do that, so there will be a leap, and how long, you'll know in next chapter.

Hope all enjoyed and see you all next time with another chapter. Stay safe from the coronavirus ya all!
