Jasper is a 6'04" tall man with a strong build, wearing a space colored cape, as well as a dark grey shirt and light blue pants. He also has an orange bandana. He also has average length dark brown hair, black eyes and a beige skintone.
Jasper is a considerate, but uncertain father. He loves his wife and both his daughters all about evenly, but has a soft spot for his daughter Pearl as he has witnessed her go through so much, and her mother has moved onto the younger Diamond, neglecting her other daughter. While Jade is not around, Jasper tries to comfort and help Pearl, while being too fearful of what will happen if he stands up for her against her mother, who is also the leader of the Space tribe as of recently. His more gentle and calm personality makes it hard for him to do what he wishes to, making him rely more on his wife to be thoughtful, but as he feels less like a husband but a second mind to his wife, he finds challenge in thinking for himself when she is around.
