Jasper is a minor antagonist on the animated series Steven Universe, and is a Gem aligned with the Homeworld.


Jasper is a Quartz-type Gem created on Earth by the Gem Homeworld. Despite the poor condition of the Beta Kindergarten she was made in, Jasper, unlike the other Gems made there, was considered to be the ultimate Quartz, stronger and tougher than the rest. She was originally made for Pink Diamond, though she was reassigned to Yellow Diamond after Pink's death at the hands of Rose Quartz, leader of the Gem rebellion against Homeworld. Despite her hatred for Rose over killing her leader, Jasper respected her skills in leadership and tactics. Thousands of years after the Gem war, Jasper was assigned to be the escort of a Peridot as she went to Earth to check on the growth of the Cluster, a Gem superweapon growing inside the Earth's crust. Jasper accepted in the hopes that she could find Rose on Earth and destroy the remnants of her army.
