Cold, clever, and crafty, Shadowstalker is a silent presence in the background most of the time. He's not one for the spotlight, preferring to stick to the shadows and observe. He's more likely to be a follower than a leader, a loyal supporter willing to use ruthless means to further an end goal, provided he trusts someone with such high ambitions; not that he's likely to trust anyone in the first place.

He's a strict cat when put in any position of authority, to the point of coming across as mean. He's also quite fastidious, by both definitions of the word; a near perfectionist by default, he borderline hyperfocuses on the details of any projects or tasks he embarks on, as well as being very particular about his personal grooming. He can also be quite lazy; he dislikes having to do more than his usual routine unless it's something he wants to do, and would rather just get things done and relax now that he's free to do so.
