We first met the cinematic version of Thanos in 2012 -- his face smiling at us during a mid-credits sequence of ‘The Avengers,’ there to let us know that this guy is the mastermind behind the whole operation. OK then! Eventually we learn that Thanos is trying to collect the Infinity Stones, because if he has those, he will become a god. Fair enough. Though, now, after ten movies in the Marvel cinematic universe – ten! – Thanos has a grand total of zero Infinity Stones. So far, Thanos is terrible at being a supervillain.
