Those are all traits of a Hunter. Every last one of them. Why do you think the traveller made Hunters? To hunt down creatures of the dark, or to do exactly what Titans do? Wouldn't serve much purpose waisting energy and power to create something entirely different, merely for it to to the same thing as the others. Hunters, such as Cade-6 are cynical and sarcastic, hunters are the fastest class, and apparently have the fastest reflexes, they are usually used for recon or scouting, the prefer to be alone and don't trust anyone who hasn't earned it.
