Avengers 4: Every Character Confirmed So Far
18. Ant-Man
Confirmed By: Avengers Facebook Group
Though he was rather shoe-horned into Civil War in the interest of adding an exceptional battle sequence, Scott Lang is now probably best considered a fully fledged Avenger, since he was driven underground along with Captain America's "rebels", even though he's temporarily under house arrest.
But he's coming back for Avengers 4, along with his new team-mate The Wasp, as was confirmed in a set video posted by The Avengers official Facebook group in support of the Hurricane Harvey fund-raising cause.
Don't be surprised if we see some sort of impressive effects-heavy action sequences showing Ant-Man and The Wasp jumping into the Quantum Realm to fight Thanos and his followers, since their solo sequel will no doubt focus on that story element.
