I like the disillusioned soldier.
I always imagined that Boba was wearing his own armour. After all, it's his size and everything.
The ESB novelisation says he's wearing the armour of a group of dark warriors that fought in the Clone Wars.
Well, so maybe Boba is the last of his group? He wears the armour out of his love for his vanished people.
I sometimes wondered if that armour wasn't clone wars-era stormtrooper armor.
