Tony looked at Bucky with murder eyes now. He was almost sure of what John had said was true but he wanted to look into his eyes when he would ask the question. Bucky who was still disoriented didn't know what was going on. He looked blankly at John.

"Are you sure John of what you are saying?" Steve asked to remedy the situation as he wasn't sure of what really happened. It's not been many days since Bucky had returned to normalcy.

"Yes. In that car accident Bucky went after Tony's parents." John said.

Tony didn't hold it as soon John said that. He directly opened his hand thruster and blasted at Bucky. Before the blast could reach Bucky, Steve defended against it with his shield. Both didn't even doubt John as he never lied to anyone and him being able to dream about other universes meant it was most probably true.

"Tony we need to talk. He wasn't in his right mind. You saw what the words of John did to him. He was brainwashed."

"I don't care. He killed my mom." Tony replied.

He flew to Bucky but Steve thew his shield to him with force. Tony stopped the shield with his hand and flung it away. Then they started having melee combat. But since Captain America was more good in melee combat he was bale to over power Tony easily.

Tony knew that and got back few steps and started flying. He directly went up and so that he could use his thrusters directly from above to Bucky and kill him.

"Aren't you gonna stop them. Tony will kill Bucky. You could have spoken of this matter much later when they are in right mind. You even equipped them with armor and suit. Why?" Banner said.

"Banner this truth needed to be out when the whole scene is under our control. They would fight it out anyways no matter what so let them fight the solution out until they both calm down. For this reason I let them use their full power. I don't want this truth to come out from a third party and ruin what we have now. Bigger and nastier wars are coming. I need us to be united. Not broken when the wars arrive." John said.

"Bigger wars?..."

John didn't reply to that and continued watching the fight between Tony and Steve. And now even Bucky joined him as after a year of calmness he could get out of subconscious control faster. In the original version, Bucky and Steve had the upper hand as the environment was closed. But here it was an open field and since John had closed the Park for today as he knew that today would be an important one Tony didn't hold back at all while fighting against them.

Bucky and Steve's melee attack wouldn't matter if Tony used hand thrusters while being far away.

"I can't let you kill him Tony. He is my friend." Steve said.

"So was I." Tony replied as he blasted two of his hand thrusters to Steve again which was defended using his shield.

"You don't deserve this shield." Tony said as he knuckled two of his hands together and flew to Steve and touched it.

There was a lightning spark around the shield as it got dismantled into two pieces. Thus the famous shield of Captain America was broken for the first time in history. Tony directly lifted Steve by his neck and threw him away a few yards.

Tony then directly had a fight against Bucky and he wanted to beat Bucky first before killing him. The anger wouldn't dissipate for him if he just killed Bucky. He had to have a close fight against him.

"Jarvis analyse his fight pattern and deploy counter measures."

"Analysed. Counter measures deployed." came Jarvis' tone.

He finally able to stop the onslaught of Bucky which was one of weakness of Tony. As soon as he stopped his hand, Tony directly blasted his thruster at Bucky's metal arm. And like the original world Bucky lost his metal arm. Only this time it was done by Tony's hand thruster instead of using the arc reactor.

This sudden attack flung Bucky a few yards behind. Even though he didn't lose consciousness he was pretty much beaten up after Tony used counter measures. Tony walked to him and asked while pointing both his hand thruster at Bucky

"Do you even remember them?" Tony said while pointing his thruster to Bucky getting ready to kill him.

"I remember everyone." Bucky replied.

"Good. I want you to ....." Tony couldn't even finish his words when a huge impact came from behind. It was Steve. He had taken two pieces of the shield and equipped in his both hands using the previous strap.

It looked almost exactly like the shield Captain America used during the infinity war. The only difference was that the shields looked irregular and out of shape. Steve directly assaulted his shoulder making Tony miss the target. He then proceeded to use both his shields to choke Tony.

Since Tony was covered in armor it wouldn't be possible to actually choke him but it would actually just stop him from moving around.

Bucky who finally got up and saw this as a chance to stop Tony. He directly put his right hand at the arc reactor. Due to super serum it was possible to at least damage the arc reactor a bit so that it could stop it from functioning and providing energy to his armor.

But what happened next was not what Bucky expected. Even John and others who were watching them fight without stopping them didn't expect the next situation. Tony directly used his arc reactor to blast at Bucky. Since his right hand was on the arc reactor it directly cut off his remaining arm too.
