R.B. "Arby" Benton was an African-American seventh-grade student at Woodside Junior High and school mate of Kelly Curtis. He was only eleven years-old having moved up two grades due to his intelligence, Arby’s only friend was Kelly Curtis. Both of his parents were doctors in San Jose, CA, and Arby was accustomed to an easier lifestyle with good, reliable parents. His mother was a gynecologist and very kind. Both Arby and Kelly worked odd jobs for Richard Levine, who was working as their teacher as part of his court order. Arby had discovered the hidden files on Levine’s computer, and thus gave Malcolm and Thorne the location of Site B. Originally, both he and Kelly were prepared to go on a field trip during school break to test out a large range of equipment that Levine had ordered from Jack “Doc” Thorne. However, they were disappointed to find that the testing session was cancelled. Not wanting to be left out of finding Levine, who had gone missing, both kids stowed away in the field trailers that were destined for Isla Sorna. Once found by the adults, Arby first acted to save them from a Tyrannosaurus. Later, during a raptor attack on the high hide, Arby fell and sought refuge in the predator cage. The raptors brought him to the nest, injuring him, until he was rescued by Levine and Thorne. He later escaped the island on a boat with the rest of the survivors.
