This is What?! - An Avengers watch the future fanfiction

Siberian Bunker Part 2

Then, Tony punches Steve, sending him flying back.

Everyone winced. (Yes, even Vision.)

Bucky raises his rifle but Tony blasts it out of his hand. Bucky tries to punch him with his robotic arm but Tony stops him with his gauntlet. Zemo smirks, leaving through a door as Tony flies Bucky across the room, slamming him onto the ground. Stepping on Bucky's robotic hand, Tony prepares to blast Bucky execution style when Steve's throws his shield. It hits Tony's helmet, distracting him and causing his blast to miss Bucky's head by mere inches.

Tony was a mix of emotions. He still felt a deal of anger towards Barnes, but now after the distance from it, he could see that Barnes was brainwashed. 

Seeing the look of dawning horror on his friend's face, Steve was once again hit with the guilt of not telling Tony the truth.

The others simply watched the two Avengers sadly. It was impossible to take a side in this, because neither of them were completely right or wrong. Both of them had messed up.

The shield returns to Steve as he rushes Tony, tackling him and forcing him off Bucky. Tony flies back at Steve, punching the shield. The force of it sends Steve flying back and Tony then fires off some electric clamps, which clap around Steve's ankles, restraining him. Bucky sends a punch to Tony's helmet but this doesn't faze Tony. Tony then grabs Bucky and flies him into the wall. Bucky quickly grabs Tony's gauntlet, grabbing it and crushing the repulsor beam focuser. Angrily, Tony tries to fire a missile point blank but Bucky moves his hand, causing the missile to wildly hit the wall. Steve breaks free of Tony's clamps as the chamber begins to come down around them.

This was worse than the airport. The airport had been about a misunderstanding, it hadn't been personal. But this, this was personal. And it was painful for everyone to watch.

In the resulting chaos, Steve rolls out of the way of the debris as Bucky and Tony are both knocked down. Tony ends up pinned under some debris, Steve shouted at Bucky to get out of there. Bucky starts to run for the exit as Tony frees himself. Tony tries to head after Bucky, shooting at him as Steve jumped in his path, standing in his way. Outside the chamber, Bucky activated a hatch, which lifted as inside, Steve attempted to reason with Tony. However, Tony is passed listening to reason at this point, ordering Steve to move as he lifts into the air.

Tony attempted to fly passed Steve only for Steve to grab onto his leg. Steve damages the thruster in Tony's boots with his shield before letting go and Tony lands outside the chamber. Tony then uses a laser to cut out some rocks, locking Steve in the chamber as the rocks block the exit. Tony tries to fly after Bucky as he sees the soldier running up towards the hatch but the damage to his thrusters has compromised his flying ability, FRIDAY alerts him. Frustrated, Tony flies up as quickly as he can and kicks Bucky down. Tony attempts to fire a blast at Bucky but Steve jumps down to Bucky, deflecting the blast back at Tony with his shield.

Steve flinched, guilty at harming Tony filling his heart. Seeing the look on his face, Sam placed a hand on Steve's shoulder, trying to let him know he was there.

Tony is knocked down to a lower level as Steve warns Bucky to leave, as Tony wasn't going to stop. Bucky begins climbing onto a higher level as Steve pulls out a wire. As Tony flew up towards Bucky, Steve jumped; wrapping the wire around Tony's neck and the two fell below.

Steve and Tony winced at this, avoiding looking at each other. The longer this went on, the more they just wished it would end. They both silently hoped it would end soon.

They landed on separate levels and Tony prepares to shoot at the hatch as Bucky nears it. Steve throws his shield at Tony but Tony blasts it, sending the shield falling down below. Tony resumed trying to blast the hatch but his targeting system had been damaged during the fight. Tony retracts his helmet, relying on his own aim. Tony fires a missile, which hits the lever, forcing the hatch closed. Bucky barely manages to avoid getting squashed as the hatch slams closed when Tony flies up to him. Bucky grabs a metal pipe and strikes Tony's helmet but Tony knocks the pipe out of his hands before putting Bucky in a choke hold, trying to crush his neck.
