After the release of Guardians of the Galaxy movie, Marvel Cinematic Universe is now rich in aliens. Would there be any alien involvement in Avengers: Age of Ultron? Any official statement or leak?
Previous to the release of the movie, leaked toy art. indicated a possible alien connection to Ultron.
According to the toy packagin, Ultron's original program is found amongst the ruins of the Chitauri attack in NY. Tony works with it and fleshes it out into a fully realized AI, resulting in the villain Ultron.
"First discovered as a simple computer program hidden among the ruins of the Chitauri invasion of New York, the being known as Ultron soon completed its development into a sophisticated artificial intelligence after some experimentation by Tony Stark. Ultron's first shocking ultimatum upon gaining consciousness was to declare the human race its enemy. Setting out to exterminate all life on the planet, the unstable and emotional Ultron seeks to upgrade its mechanical body to an ultimate, unstoppable form. With an army of robotic drones and the ability to enter and corrupt any computer network, Ultron will stop at nothing to see humanity wiped out."
However, as we learned in the final cut of the movie, the leaked art is close, but not entirely accurate.
Ultron is created using
"code" found in the gem of Loki's scepter, which was lost during the Battle of New York.
However, we learn that
the gem in Loki's scepter is actually an Infinity Stone,
meaning that the creation of Ultron has nothing to do with the Chitauri (aside from them being involved in the battle that brought the scepter to Earth), but is easily argued as being alien-based. There is, however, no direct alien involvement in the movie,
unless you count Thanos, who appears to be attempting to manipulate events surrounding the Mind Stone.
