Gordon Gekko is a fictional character in the 1987 film "Wall Street," directed by Oliver Stone. Gekko, portrayed by actor Michael Douglas, is a ruthless and charismatic corporate raider who is willing to do whatever it takes to make a profit. He is a symbol of the excesses and greed of the 1980s, and his character has become a cultural icon.

Before starting his own company, Gekko worked as a stockbroker and became one of the most successful traders on Wall Street. He was known for his ruthless tactics and willingness to take risks in pursuit of profits. Gekko was also infamous for his "Gekkoisms," which were pithy sayings that encapsulated his philosophy of greed and self-interest.

Despite his success, Gekko was not satisfied with being a mere trader. He had ambitions of running his own company and making even more money. In the film, he famously declares, "Greed, for lack of a better word, is good. Greed is right, greed works. Greed clarifies, cuts through, and captures the essence of the evolutionary spirit."

In pursuit of his ambitions, Gekko takes on a young and ambitious stockbroker named Bud Fox, played by Charlie Sheen. Gekko recognizes Fox's potential and takes him under his wing, teaching him the tricks of the trade and introducing him to the world of corporate raiders.

With Gekko's guidance, Fox becomes more successful and begins to make a name for himself on Wall Street. However, as Fox becomes more involved in Gekko's schemes, he begins to see the darker side of Gekko's personality and the lengths he is willing to go to make a profit.

Gekko's downfall comes when he is caught engaging in insider trading and is arrested. In the film's climactic scene, Gekko delivers his famous "Greed is good" speech to a group of stockholders, but his words fall on deaf ears as he is led away in handcuffs.

Although Gekko is a fictional character, his legacy has endured long after the release of "Wall Street." He has become a cultural touchstone for the excesses of the 1980s and a symbol of the dangers of unbridled greed in the corporate world. The character has been referenced in numerous films, television shows, and other works of popular culture, cementing his place in the collective imagination of the public
