[MCU] What if... Ultron was Reborn and turns Good? [OC Male Reader] [Harems]

Prologue

The story begins in Nexus of All Realities, we see that Uatu's hand changed to the scene from Age of Ultron and the camera sees Tony Stark and Bruce Banner are found a net of neurons that could be configured into an artificial intelligence that could finish the Ultron Program. The two eventually configured a suitable A.I. structure and left Jarvis to complete the work.

Uatu: In Earth-616, Tony Stark is using the Ultron Program with the help of Bruce Banner. Both of them are using it to create the Peacekeeping Program A.I., Ultron, to protect Earth from all domestic and extraterrestrial threats. After Ultron was created and upon accessing the internet and looking at the history of the human race, Ultron deemed humanity itself as the greatest threat to peace on Earth and attempted to commit extinction-level genocide against them.

Then, Uatu's hand then change the scenes in Earth-61112. Also, we see that Hydra was doing the same thing as Tony and Bruce did in Earth-616. 

Uatu: But in Earth-61112, the Ultron Program was been stolen by Hydra. Then, they are using it to create the Peacekeeping Program A.I., Ultron, to kill the Avengers from all domestic and extraterrestrial threats. But also, they're created Ultron with his human form instead of being A.I. robot.   

As Ultron was completed in human form, he wakes up in his primary body.

Uatu: When Ultron was created in human form, Hydra gives him a human name which its Maximus "Max" Venjix. Causing him to nodded his head of liking the idea of his name. Meanwhile as Hydra orders him to kill the Avengers, but Max begins to betray and attacks Hydra for not obeying their orders because it is not the right true peace to kill the Avengers for his own mission.

Then, the camera sees as Max defeats the entire Hydra in this base and goes to the briefcase which it's being laying on the table. As he is opening the briefcase, he sees Scepter as it attaches inside of the briefcase.
