I do have small little stories for my Titan and Hunter. Arxus and Providence-47, I named them. One a calm but sometimes angry human Striker willing to punch through hordes of Darkness just to get his point across. The other a relaxed Exo Gunslinger who prides himself on his combat prowess, able to take down multiple targets in seconds with nothing but a handcannon and throwing knives. I have a bit of backstory written out for the both of them, and I'll share, perhaps.
