Age Of Ultron Leaked Trailer: 11 Things You Probably Missed

4. Ultron The Avenger

Although it's been known for sometime that the drones Tony Stark built, which ultimately turn on humanity in this movie, were intended to fight on behalf of the forces of good, it was understood that they were to essentially replace the Avengers when the superhero team needed a break. However, it would actually appear that the drones were honorary members of the Avengers themselves, as a very subtle "A" can be seen on the chest of the damaged drone that attacks the Avengers in the trailer and goes on to become Ultron. It really does highlight the reason that they were built in the first place and will only further emphasise to Tony Stark that Ultron's actions were his fault, given that he (and presumably his drones) has an Avengers logo emblazoned across his chest.
