Bruce reached the laboratory only to see Stark crawling towards the previous arc reactor which Pepper gifted him. His original arc reactor was missing from his chest. Bruce ran to the old arc reactor and placed the it in his chest.Tony finally returned to normal after few minutes.
At that point Rhodes too came and saw Tony getting ready in the suit. "This is the coolest thing I have ever seen" Rhodes said.
"Tony, Obadiah took away your reactor to fuel his own version of suit he got from your Mark 1. You will have to be careful." Bruce said as he himself started to put his suit.
"You are?" Rhodes asked feeling weird because he had never seen this new person before and from his words it felt like Tony and him are good friends but he had never seen him before.
"Bruce Wayne. A friend of Tony. We can talk about myself later. We have to go now. Alfred, Jarvis guide us when required" Bruce said.
"Sure sir." both said immediately.
"Rhodes keep the sky clear for us" Tony said after putting his suit on.
"Jarvis bring out the TUMBLER, Alfred I might need the batwing. Take it's wheel. " Bruce said. Bruce had brought all the 3 vehicles in the garage as he needed some modification to do. The batmobile came near him as he went to the garage. He went inside while Tony flew away.
Rhodes was stunned when he saw such a huge vehicle and wondered where he had seen this vehicle before. "Hello. Can I know who is he?" Rhodes asked Alfred as he saw them riding away.
Alfred just smiled but didn't say anything as it's not his secret to say.
Tony reached when Pepper was about to be attacked and fought with him but the fight led to the streets. It happened exactly as the same in the original world. But as soon as the fight started in the streets suddenly Obadiah was hit by big bullets from behind. Even though the bullets failed to penetrate the armor but it dented the armor by lot. Bruce realized that Obadiah had changed the exoskeleton because the bullets in the batmobile didn't pierce the armor.
"Tony, he has upgraded your armor." Bruce said over the network.
" Who are you? Well! It doesn't matter. Since you shot me now it's my turn" Obadiah said and immediately launched a missile towards the batmobile and it exploded immediately after it was hit.
"No Bruce.. You piece of shit" Tony shouted in an agitated voice and Tony started fighting after against Obadiah.
"You care about a person's life who you have probably met a few days ago. You disappointed me Tony." Obadiah said. And while they were fighting Obadiah was hit by a small device on his neck and it exploded immediately after. The device came from exploded Batmobile. And from there emerged a motorbike with huge tires and mounted guns on both sides and a man in a batsuit riding it.
After coming out of the fire he immediately started raining bullets on Obadiah and he was thrown away by the impact as the bike was up close now. "We need to disable his suit. Take him to high altitude. His suit will develop ice on its armor." Bruce suggested after approaching Tony riding the bike.
"Yes. Where is your batwing? We need it" Tony said
"We are here Master Stark. Now mount him over the plane. Be sure that he doesn't fall of" Alfred said over the call.
Bruce and Tony immediately went towards Obadiah who was lying down. Tony sent a missile to Obadiah while Bruce threw incendiary device at him which exploded immediately. Obadiah who was trying to get up got blasted away again and became unconscious. Tony put Obadiah over the batwing after spending a lot of energy as the Obadiah's suit was really heavy. The batwing immediately flew away to high altitude while Tony made sure that he doesn't fall down from the batwing.
They went to high altitude and icing started to form on Obadiah's suit. After a certain altitude, Tony threw him down.
Tony, whose energy on his reactor was negligible started to come down and Alfred gave him a lift at the end as he saw Tony working on fumes. Obadiah didn't survive the fall as he was unconscious and his suit was heavily damaged from missiles and bullets before.
A day later after the fight John, Bruce, Coulson, Tony, Alfred and Pepper were in a room. John came in the next morning when he saw the fight happen in the streets. Though there was a huge change in the plot but the general trajectory was the same. It reinforced his belief that even if there was a butterfly effect on the events but still it didn't change the actual heroes' story very much. John came to see that famous scene in the press conference that will mark an era to come.
