Next year Avengers: Infinity War explodes into theaters. The film will see 10 years worth of Marvel heroes created on the big screen uniting for a battle against their toughest opponent yet: Thanos. At Disney's D23 Expo over the weekend Marvel Studios revealed this battle to be even more of a challenge than anyone had previously imagined. One of Thanos' main goals in the Infinity comic was to find his son Thane. Thanos dispatched four members of his elite guard, The Black Order, to find him. However, in the Avengers: Infinity War movie, these characters will be the children of Thanos. This major change was revealed by the host at Marvel Studios' booth who introduced each character individually before calling them the "children of Thanos."
