Marvel Studios’ second trailer for Ant-Man and the Wasp sets up Cassie Lang to become a fully fledged superhero in Avengers 4. When Peyton Reed’s Ant-Man debuted in 2015, following on from Marvel Studios and closing out Phase 2 of the Marvel Cinematic Universe, only Scott Lang received a super-suit. However, there were teases for plenty of other characters to suit up; Hank Pym had once donned the Ant-Man suit alongside his wife, Janet van Dyne, who took the mantle of the Wasp.
