4. Ultron Vs. Everyone (Almost)
One of the coolest things about this trailer is the fact that we get to see a lot more of Ultron himself in action. Everyone is obviously an exaggeration, but we do get a glimpse at what appears to be a very brutal beatdown for Captain America, and Thor later getting electrocuted by someone we have to assume is indeed Ultron at this point. Him firing a red energy blast is also visually very exciting, and while you might think that one robot (who does admittedly have a robot army backing him up) should be an easy foe for a whole team of Avengers to take down, this trailer smartly establishes just how menacing and powerful Ultron is!
