The Vision as portrayed in the Avengers movies - generally has more valid viewpoints than anyone else on the screen. Flies like a rather muscular ballerina. Also, he's played by Paul Bettany. I'm sure he's interesting in the comics, too, but I can't comment on what I haven't read yet. Coincidentally, when I played a Captain America-focused video game as a child, I always chose to play as Vision, mostly because he could fly.
