The odd possibility of Ed and Spike being related came to mind with the above image. Little is known about Ed's family, and even less is known of Spike's. The animated version of Cowboy Bebop was spawned from 2 seperate mangas, Shooting Star Bebop and Cowboy Bebop. In Shooting Star, Spike's face is horrifically (i made that up, i think) androgenous, as Ed is through the entire series. They're also both tall, lanky, and sport unruly mops of hair.
