Andrei Strasser is a greedy poacher who captures and exploits wild animals for profit. He is responsible for capturing Joe, a giant gorilla, and bringing him to the United States for exhibition and exploitation in a nightclub. Strasser's actions and mistreatment of Joe become a central conflict in the film.

As the antagonist, Strasser's character represents the exploitation of wildlife and the harm done to animals in the pursuit of profit. He is confronted by the film's protagonist, Jill Young (played by Charlize Theron), who forms a bond with Joe and seeks to protect him from Strasser's cruel intentions.

"Mighty Joe Young" is a remake of the 1949 film of the same name and is known for its heartwarming story of the relationship between Jill and Joe, as well as its portrayal of the need for wildlife conservation and protection. Strasser's character serves as the embodiment of the film's message against animal exploitation.
