Just so, will Ant Man go up Thanos?
By now, almost everyone in the world has seen Avengers: Endgame, which means we're all aware that Ant-Man does not crawl into Thanos' butt and expand, thus killing the Mad Titan from the inside out.
Likewise, how did ant man kill Thanos? The theory is that Ant-Man (played by Paul Rudd) will defeat Thanos by crawling up his anus and expanding inside of him. One theory stated that Hulk would borrow Ant-Man's suit, shrink down in size, crawl into Thanos's mouth, and journey into his digestive system, before taking him down from within.
Beside above, did Ant Man fight Thanos?
Fans expected Scott Lang (Paul Rudd), better known as Ant-Man, to make an appearance to help fight Thanos (Josh Brolin) and protect the Infinity Stones. Both Ant-Man and the Wasp are slated to show up in “Avengers 4,” so this solidifies that their exploits are going to be a factor in the conclusion of the Thanos story.
Why didnt Antman fight Thanos?
Actually if he shrunk himself small enough he could have theoretically punched thanos skin or flew into his nose and then did havoc from the inside. They obviously couldnt do it because it would have ruined the movie but a millimeter or smaller ant man inside thanos would have really hurt him badly.
