I was thinking maybe a little bit more of a Robot concept, with a sort of “Gunslinger” idea.
His name is “S0R3N The CyberTech”.
Long story short, he is a robot that was programmed to hunt for the vaults all over the galaxy, but after the Hyperion Corporation fell he went dormant for years until Gaige found him while scrounging for scrap metal, and repaired him but has no memory of the Hyperion corporation or Handsome Jack, and went insane over the fact he cant find out where he came from, but still wanted to find the vaults, so he went out with the vault hunters on there quest for the vaults.
If you have a better backstory be sure to let me know, but most of the action skills are based on the back story.
