However , in the gruesome futurity Marvel Comics has written for Earth ’s Mightiest Heroes , the scoundrel who beats the Avengers is revealed - and it ’s not Thanos .

The futuristic landscape painting in which the Avengers have grown old , festering in their bang-up failure , is chronicle inAvengers : Twilight . The record follows Steve Rogers after the Super - Soldier serum was take out from his body , and he formally retired from being Captain America . Steve stays in touch with Luke Cage and Matt Murdock , all of them old men disenchant with the state of the world since the superheroes were ram to fall up their proverbial ( and , in some instances , genuine ) mantle .

Ultron Is The Avengers’ Ultimate MCU Villain, Not Thanos

InAvengers : Twilight#1 by Chip Zdarsky and Daniel Acuña , Rogers is invited onto a talk show to discuss a docu - series that sought to frame Red Skull as a secret bomber , and Captain America as the man who got in the way of Red Skull ’s ‘ righteous ’ efforts to take down Hitler from within .

Ultron had a personal relationship with Hank Pym , and he hated the Avengers with every fiber of his being . Ultron was n’t trying to decimate the creation or court Death , his only goal was to see the Avengers squirm , and he used his unequaled , cybernetically enhanced intelligence to do it . Ultron did n’t just beat the Avengers , he made the globe detest them as much as he did , which is how they stayed beat up .

Ultron Has Always Been The Avengers’ Ultimate Villain (& Should Be Again)

Ultron ’s term of office in the MCU was shamefully short - hold up , as he was defeated bare solar day after he came on-line inAvengers : Age of Ultron . for sure , he prove how really deadly he could be in the What If ? serial , but that ’s an alt - universe Ultron . Ultron in the MCU ’s primary timeline was nothing compare to MCU ’s Thanos , but time and again in the comics , Ultron proves to be the worst of the worst , andAvengers : Twilightis just the in vogue object lesson . Ultron ’s hatred of the Avengers is unequalled , as is his genius , and he needs to make a comeback in the MCU .

Ultron being the Avengers ’ ultimate endgame in the MCU would not only deliver the character himself , but also more accurately portray Ultron ’s arch - enemy status opposite the Avengers . Thanos never really cared about Earth ’s Mightiest Heroes , they just kind of make in his direction a few prison term . But Ultron hates theAvengers , and fans can find that in the lamentable future show inAvengers : Twilight , which is why it ’s stark that Ultron is the villain who actually beats them , notThanos(and why Ultron should do so again in theMCU ) .
