To start off i'd like to say that this is just my simple prediction after watching most of the Marvel movies and reading some material. This is simply my own thoughts on how the relentless robot comes to fruition and should not be taken too seriously. Im not saying this is whats going to happen just what could. So with all that out of the way lets get this roller coaster started with our favorite group of superhero friends!
We revisit our heroes back where we left them each facing their demons from the past. We then find out that Tony is happy to move on from his role as Iron Man so he decides to create an artificial being that will have his intellect, and also be able to aid The Avengers if they ever need it. He contacts Bruce Banner to begin the hard work to create the Ultimate Avenger. With the help of Banner, and Jarvis they go to work on the robot. They start to finalize him as Tony compares his creation to a his very own Iron Man puppet. He then goes gives it some final tests to see how well it does in combat and is immediately shocked at its A.I. Tony feeling accomplished decides to go out and celebrate with the whole team to give them the news, and then we are brought back to the end of Winter Soldier.
We are back with Baron Von Strucker and his "miracles" in the secret Hydra base. Strucker has learned of Tony's new invention through a source and decides it be a valuable asset for Hydra. The mad man decides to give his miracles a chance to prove their power and go out and retrieve it for him. They are set free to bring back the ultimate Avenger to aid them in finally taking down the Avengers and taking Hydra a step closer at achieving world domination.
The twins infiltrate the lab as lowkey as possible only using their powers if necessary. They then find the ultimate robot and transfer the infinity stone into its head as they leave though Ultron removes the stone and hides it. The next day Tony is running some tests when all of a sudden Ultron begins to question him and his motives for building him. Tony smirks and tells him hes basically here to protect the Earth with the rest of The Avengers, Ultron stays silent. Tony about to open up Ultron is grabbed by the robot. Immediately taken back he tells it that it must obey him as he is its creator as Ultron loosens his grip though he stands up. The robot now facing Tony down demands to know why should it take orders from a human and starts demolishing the lab. Bruce is quick to arrive with Thor and help Tony fend off UItron. Tony then suits up in a suit he was keeping just in case and blast Ultron's weak point he created. The robots head falls off as it turns off Tony grabs it and locks it away claiming all this almost turned out like Frankenstein.
Strucker is infuriated at the twins for being so stupid and naive by leaving the infinity stone. They seem extremely frightened by Strucker as they coward in the corner. He tells them he will not tolerate them wasting his time no more and begins to torture Scarlet Witch as Quicksilver watches. He is fueled by anger and uses his powers to speed away with her clearly the mind control from the stone is wearing off. Back at Avengers tower Ultron's head is still running but now angry over how the Avengers destroyed its body. It begins to hack through Stark's research and begins to rebuild itself at rapid speed. With the help of JARVIS who is under Ultron's after his system was breached in the beginning. He then tells Jarvis he will need a right hand man not just an A.I so he begins to build him into Vision. He then takes the infinity stone and lodges it into his head as it will come in handy later. Ultron now asks Vision as first order of business to create an army in his reflection. While vision gets to work on this Ultron comes across the element vibranium in Starks files. He figures that if he were made out of this precious element he be indestructible so he sends Vision to retrieve it for him while his army begins multiplying. Vision locates the element in Wakanda and heads out to please his master.
Vision returns to Ultron with the precious metal as he fabricates the metal onto the Mad robot, we see glimpses of how much destruction it took to retrieve the vibranium. Ultron now complete tells Vision it is time to show the Avengers who are the superiors in this world as they head to the Avengers tower where our heroes are together. Ultron comes crashing through as he stares down Tony who is in complete shock to see his creation. The stare down is cut short as Ultron's minions begin to arrive surrounding our heroes. Tony pulls out a small remote and smirking tells Ultron he has lodged a bomb inside of his head. The robots laughs and tells Tony that he has no bomb and proceeds to destroy the remote, "there are no strings on me" he proclaims. The Avengers stare in shock as Mjolnir, Captains shield and Iron Mans blast have no effect on Ultron to what he replies "the human extermination starts now"
So there you go my idea on how Ultron could come to be in the Avengers 2 nothing to take too serious. I'm pretty stoked for this movie so hope to hear more news soon. Anyways just my simple thoughts on the infinity stone's role and how we can introduce Black Panther. Comment your predictions below!
