I kind of hate how Tony Stark is a tech god in the MCU. I can't stand how it's one man who does all of this and no one else can compete. I know they can't have Reed Richards, but Bruce Banner is smarter than Tony Stark (something we will never see), Hank Pym is at least his equal though with a shit ton harder on himself for every little failure. I just think it's a cop out that they make Tony Stark such a focal point in the entire Universe.
That said... what does Ultron look like? On the cover, he looks kind of like he does in the comics (IE Pretty Awesome). If you click on the link in the article, he looks terrible.
