James Hammond was a male Human clone from the planet Mariposa. He was created in or shortly before 2365, from the 15th generation cell line of Mariposan Progenitor John Hammond. He was just out of Incubation and had just begun Imprinting when the USS Enterprise-D visited Mariposa and put an end to their practice of cloning.
By 2376, Hammond was head of the Alliance for Mariposan Primacy, an anti-Bringloidi group, and launched a short-lived coup d'état in the wake of the accidental release of a genetically engineered pathogen on the planet. He was eventually arrested by Security Minister Kevin Hammond. (SCE eBook: Out of the Cocoon)
