No Jagged Fel is the head of the Imperial Remnant, and Admiral Daala (yes that evil Imperial bitch from the maw cluster who tortured Han) is the head of the Galactic Alliance.
Me i like Canderous Ordo from the Kotor games as the Mandalore, though Fett is not half bad.
The Sith War comics pretty much set up the fact that the sith used Mandalore and the mandalorians as their goons. Which explains why Fett has a business relationship with Darth Vader other than the fact that the Empire is the legitimate government and the rebels are terrorists and criminals, or at least that is the imperial view.
To me Fett was never meant to be anything but a Foil for Han Solo to be played off of. Kind of like Belloq to Indiana Jones in Raiders of the Lost Ark. Fett gets his coolness from being mysterious, as Lucas said he was kind of modeled on Clint Eastwood who played the man with no name in the famous trilogy by Sergio Leone.
Once fett is no longer mysterious he is no longer cool. The prequels ruined him as a cool character in the same way they ruined Darth Vader.
The funny thing is the most interresting part of Vader's story was left out of the movies. How he is in the between time between Episode III and IV. How he hunts down the Jedi. His obcession with hunting down and killing obi wan kenobi, He transition from a Sith Apprentice into a badass Sith Lord who makes all tremble in fear of his presence. Funny though he is just a weak incomplete man in a suit, he lost his humanity to serve an imposed system of rule by an iron fist.
Also he never was shown as the morally compassionate, champion for the people and a knight in shining armor When he was known as Anakin. Other than for a start in Episode 1 he is shown as a little slave boy who knows nothing of greed. Once we get to Episode II though, the whole slave angle is dropped as well as Anakin starting out a good dude and becoming bad. He is already a selfish Jerk. Kills all the women and Children and male warrior sandpeople in revenge. A Jedi must never succumb to revenge. Revenge is of the dark side.
It is clear though he does not really cross over the abyss until he is compelled by palpatine to do his first pre-meditated murder. Count Dookus only reason for existing was to push anakin over the brink. Still he was only wading in darkness and was not drowned in it yet. He was not consumed by it until he was manipulated by his emotional attachment to padme to save her from dying. Ironic that his attempt to change fate is what causes her death.
Plus yoda already hit on a critical point in the phantom menace. Anakin was affraid to lose his mother, which grew into a selfish desire to prevent people from dying no matter the cost. His Fear, his inability to let go. To be serene like a good jedi, to surrender all emotional attachments. Fear truly is the path to the dark side. lol.
