Confirmed "Avengers Age of Ultron" spoilers peg the team's villain as humanoid, also develops an origin story.

With "The Avengers: Age of Ultron" hype in full swing, rumors and leaks of the characters and plot reach an all-time high. Leaked on-set photos confirm Scarlet Witch and Quicksilver are indeed part of the next assemble, and the end credits reveal as much on the next installment for the franchise.

So much have been revealed and speculated on each Avenger, but their nemesis Ultron remains a black character in the black-white spectrum. New spoilers hint his intentions for planet Earth aren't as sinister as it may seem, though.

The cast of "Avengers 2" is set to return in a Marvel panel at this Saturday's comic-con, expected to reveal the names of new and returning characters in the sequel. There's still hope Spiderman will make an appearance, even if only as cameo.

Entertainment Weekly teased fans with their latest cover, though, putting Iron Man and Captain America on the forefront, with an ominous Ultron looming in the background. If the cover confirms Ultron's semblance in the film, then it's likely fans of the comics had their way with the newest "Avengers Age of Ultron" spoilers.

Ultron has retained his design from the graphic novels, although it's unlikely Marvel Studios will keep it that way. It's reported the design is initial and will change later on as the film's plot unravels.

James Spader lends his voice as Ultron, a villain with heroic, noble origins. In "Avengers 2," S.H.I.E.L.D. has stepped out of its responsibilities as the Earth's defense, and the Avengers has taken it upon themselves to ensure this.

Tony Stark comes up with an idea of defense that also liberates him from ever wearing the Iron Man suit. He creates Ultron, and the plot thickens. More "Avengers Age of Ultron" spoilers are expected to leak out as the sequel nears its screen date (ibtimes.com).
