Avengers: Endgame was full of moments that had fans talking months and months after release. One fight that viewers never got to see was just revealed in the Avengers: Endgame artbook. Thanos has conquered thousands of worlds by the time he reaches the heroes inAvengers: Infinity War. But, there was one struggle between his forces and some aliens got left on the cutting room floor. The people on that alien world had access to some sort of futuristic technology that gets shown off in great detail over a couple of pages in the artbook. However, like so many before them, they just couldn’t stand before the might of the Mad Titan. Endgame was already a pretty lengthy movie and it is interesting to see how many of these details just couldn’t make the final cut. The film could have easily ended up being four hours or more if these tough decisions didn’t end up getting made.
