Jamie has come to the USA for his graduate studies in Accounting. To support himself financially, he used to fight as a mercenary for Commodus.
For some reason, Commodus and Jamie got into an argument. Commodus became angry and began to suspect that Jamie might betray him. Hence Commodus put Jamie in prison.
After Apollo freed Jamie from his prison, he fought against Commodus's army to protect the Waystation.
Jamie is described as tall, glossy dark-skinned and handsome by Apollo, with the latter swiftly developing on crush on him. He has a muscular build, a shaved head, and a booming, thunderous voice. He wore only a red-and-white loincloth with matching beads around his neck, but he did not seem underdressed. His eyes were teak brown, piercing and angry but beautiful in the way only dangerous things can be. Tattooed on his right shoulder was a symbol that looked like some sort of a double-bladed ax.
- Electrokinesis: Jamie is able to generate red-colored electricity, as he has demonstrated during his fight against Commodus' forces.
- He is the first demigod introduced in the series who is neither Greco-Roman or Norse. He is revealed to be ethnically Yoruba, a people that comprise over one-fifth of Nigeria's population.
- Apollo noted that Jamie's fighting style is similar to the children of Zeus/Jupiter.
- Jamie's possible godly parent is Shango, the Yoruba god of lightning, due to his Electrokinesis.
- A curious difference exists between the physical and eBook editions of The Dark Prophecy, where instead of Jamie, Olujime is called Jimmy.
- Jamie seems to know how to interact with ostriches to make friends with them.
