Ant-Man and the Wasp: Quantumania will see Scott Lang, Hope Pym and many other characters go up against the biggest threat yet: Kang the Conqueror!
An image of Ace Ruele wearing a stunt team crew merch has surfaced in a tweet from November 22, 2021.

If you look closely, Kang is in the reflection and it also appears that Scott will take a beating or at least his helmet is broken, likely by Kang.

A variant of Kang called He Who Remains played by Jonathan Majors recently appeared in the 2021 Disney Plus series Loki. In the nex Ant-Man movie. This will be another variant also played by Majors.
Ant-Man and the Wasp is currently set for a release date of February 17, 2023.
