Astley Sparkes is sexy doctor on board The Raptor, and part of it's elite hitsquad. His drive is to meet sexy aliens (though he is not opposed to becoming captain).
He is “best characterised by a man leaning back with his arm’s crossed” and being closer to a closer to Brad Pitt look than a George Clooney look. He is described as being slightly older and slightly tan, an angular nose, and having three day’s worth of not shaving, with thick black hair that has a slightly receding hairline (that he is not self-conscious about) which is about 20% grey hair, with more grey in the beard than his hair.
