Gumshoe
During his time as a detective, he has made many enemies over the years. He was always nervous that his daughter would prove tempting to some of his less savoury opponents. These fears eventually came true, upon finding out that his daughter was kidnapped by a mafia boss known as King Dom. His ransom was no less than the five Black Panther diamonds that had been lost. Stevenson knew where they might be found, so he set off to claim them.

His travels to find the five Black Panther diamonds took him across highways, across deserts, into deep jungles, and on top of rooftops. Upon finding the fourth Black Panther diamond, he was given a machine gun in order to fight off the monster of the jungle, Zulie. Once he Zulie was defeated, he found the fifth Black Panther diamond and encountered King Dom face-to-face. King Dom held a gun at Mr. Stevenson, but a random gunshot made King Dom drop his gun. As Mr. Stevenson suspected, he had been followed the entire time by a marksman, and thanks to him, Mr. Stevenson's daughter was returned to him and the five Black Panther diamonds were returned to their rightful places.
