The most charismatic anti-hero.

Yes, they have some issues with names there :) Several Sandros, several Alamars, and Krodos. And Lord Haart seems to participate in the War of the Succession and at the same time, he seems to live in Erathia.

I got a bit sidetracked ;) I think Archibald Ironfist is the most charming anti-hero. And what emotional turmoil he had to endure! (Might and Magic VII) Sandro is just too cliché.
