He's ambitious as all hell, a competent leader to those who've served under him long enough and a terror to those who haven't. Good at recruiting and commanding child soldiers. Was once a prominent ladies man, and had a right hand woman who served as his moral compass and limiter on his actions. The kind of man who could lead a nation, and pines for that power because he knows in his bones that he can use it for the right reasons.
War veteran who did a lot of unsavory acts for a cause he didn't believe in, but followed orders because he knew it was the best way to get the power to change things.

I could go on, but think that is good for now.
