15 Crazy Facts You Just Have To Accept To Enjoy The Marvel Cinematic Universe

2. Thanos Probably Won't Fight The Avengers Until 2018

Thanos was first introduced into the MCU in the mid-credits sequence of The Avengers, and the only glimpse seen of him since was in Guardians of the Galaxy, voiced and mo-capped by Josh Brolin, and basically, looking freaking awesome. Still, while he does feature in the plot for Age of Ultron, Thanos won't be facing off directly against the Avengers until the third film, which means a lengthy wait until 2018 before this slow-cooked tease finally gives the payoff fans have been desperately waiting for. What Can Be Done About It?: Nothing. Hopefully Age of Ultron will give fans a lengthier glimpse of the big guy, though this one's all about playing the waiting game until the summer of 2018, sadly.
