Avengers: Endgame 3rd Act Pitch Keyframe

We were asked to come up with interesting Tag-Teams and Action "Gags" for Avengers: Endgame's 3rd Act. Antman is incredibly powerful if you don't think of him only as comic relief. What if he enlarged his ant army? The Chitauri won't stand a chance! This is my pitch to take on the Leviathans.
