Tony pushes past his grief over Jarvis' death and Natasha's betrayal and suits up as Iron Man. Jarvis' death was simply an act of cruelty on Black Widow's behalf, using their constant friction as some kind of justification when he was simply a victim of circumstance.
Tony said he saw "a suit of armor around the world," and that he needed Ultron to run the Iron Legion. But JARVIS was already doing a pretty decent job of that, and he didn't seem to have reached the height of his capabilities.
What Makes Him Pure Evil? He betrayed his creator Pym mere moments after being created, quickly deemed humanity as flawed and has made numerous attempts to wipe out the entire race. He attempted to destroy any of his own creations, such as Vision and Jocasta, when they rebelled against him.
Voiced by Paul Bettany, the AI was created by Tony to function as his main assistant. Being extremely secretive and cautious, JARVIS also served as Iron Man's company and even his friend. So when JARVIS was essentially killed by the corrupted Ultron in Avengers: Age of Ultron, Tony was understandably distraught.
Ultron sees the Avengers as one of the main problems with the world's stunted evolution. He particularly dislikes his maker Tony Stark and flies into a rage when compared to him.
But if you want to know why he came so close, it's because he is a far more advanced AI than Jarvis. Jarvis was created just from Tony's genius, nothing more. Ultron was created using the sentience of an Infinity Stone, the Mind Stone. His AI is faster-learning and arguably smarter than any human mind.
Ultron Mark-12 debuted in Vision and Scarlet Witch #1 in 1985 as a villain, but over time came to reconsider his actions, and decided to become a good guy. Created by Steve Englehart and Richard Howell, his heroic career did not last long, and this version has been all but forgotten.
Moments before Vision destroyed him, Vision pointed out that Ultron was afraid of death, to which Ultron didn't even bother to deny as he admitted that he was afraid of Vision despite standing up to him.
J.A.R.V.I.S. is an artificial intelligence created by Tony Stark, who later controls his Iron Man and Hulkbuster armor for him. In Avengers: Age of Ultron, after being partially destroyed by Ultron, J.A.R.V.I.S. is given physical form as Vision, physically portrayed by Bettany.
Edwin Jarvis appears in Ultimate Avengers 2, voiced again by Fred Tatasciore. James D'Arcy reprised his role as Edwin Jarvis in the MCU film Avengers: Endgame.
might just not have the technology to detect Tony's new suits. Tony's new, more highly advanced technology was made to be undetectable/untraceable to his earlier tech.
Ultimately, the Avengers foil Ultron's plan by destroying Novi Grad once it has been evacuated, while Wanda and the Vision destroy Ultron's body and Ultron himself respectively, ending his threat. An alternate timeline version of Ultron appears in the Disney+ animated series What If...? (2021), voiced by Ross Marquand.
Thanos would have been expecting as much. Ultron, however, is not natural. He is completely logical (and fast) in his thinking, and know that there is no purpose in melodrama. So he acted fast, and sliced Thanos into two perfectly balanced halves.
Tony Stark uploads F.R.I.D.A.Y. In 2015, after J.A.R.V.I.S.'s matrices were uploaded into the Vision, Tony Stark sought to find a replacement user interface program for his Iron Man suits. Sorting through a pool of back-up programs that included ones named J.O.C.A.S.T.A. and T.A.D.A.S.H.I. , he selected F.R.I.D.A.Y.
A machine can pick up the weapon and move it anywhere since it's mindless and incapable of possessing the morals necessary to be considered worthy. By this logic, Ultron himself could have lifted it, but it wouldn't have done him much good.
In Marvel's What If…?, Ultron used the Mind Stone to instantly bisect Thanos before the two could properly fight. In a fight without any Infinity Stones, however, Thanos would destroy Ultron, further cementing him as one of the MCU's deadliest threats.
Steve was a weapon that was used to fight the enemies, in a way he was a part of the war. But despite having the choice later to give up on fighting and choosing a normal life, he decided to keep being Captain America. That's why Ultron was disgusted by him.
The technology of Ultron is so powerful that two of the most dangerous Avengers can get insta-killed casually without either seeing it coming. Ultron defeated both She-Hulk and the Hulk not by outsmarting them or even besting them in a real one-on-one fight, but by overwhelming them both with his strength.
He's a robot, an unfeeling machine with no way to comprehend the concept of pain, but she warped his existence so he could actually feel, just so he would suffer in this moment.
He even called down the lightning, just like Thor. Now, Kevin Feige has confirmed that Steve Rogers was indeed always worthy, but did not lift the hammer out of respect for Thor in Avengers: Age of Ultron. In a Reddit AMA, he said, “We think he was always worthy, and was being polite in Age of Ultron.”
This is a huge and humiliating end for the Asgardian trickster, and proves that as powerful as Loki is, even he cannot resist the technological terror of Ultron.
Jarvis uses several artificial intelligence techniques, including natural language processing, speech recognition, face recognition, and reinforcement learning, written in Python, PHP and Objective C.
Over time, he was upgraded into an artificially intelligent system, tasked with running business for Stark Industries as well as security for Tony Stark's Mansion and Stark Tower. After creating the Mark II armor, Stark uploaded J.A.R.V.I.S.
