The Master is

Mad and insane, I mean, who else takes over the world to 'Here come the drums' by Voodoo Child

Arrogant and very cocky, but one of everyone's favourite bad guys, even better than the daleks

Sexy, oh so very sexy, especially with that mop of messy blond hair, love the blond hair

Talkative, all enemies are, it's like get on with your evil plan already I'm board

Eccentric and very very hyper, I swear him and the Doctor are like small children fighting over their favorite toy (the earth)

Reckless, only he would piss off the doctor on purpose, just for the hell of it or maybe he was board
