Rock's facial structure is seemingly identical, to that of Jeff Pleasant. According to his SimDNA in SimPE, his hair was blond before it turned grey. According to Rock's age information, he had 14 days left in the elder life stage when he died. As with many pre-made Sims in Strangetown, the "Skintone" part of Rock's Sim DNA is missing. He has no skill points, like most other deceased Sims, contradicting his eligibility for promotion to General.
This Sim has no character data and cannot be resurrected in-game. For more information, read this guide.
