Dr. Mardock (マードック 博士 Mādokku Hakase ), sometimes translated as Dr. Murdoch, is a character and a recurrent antagonist in the TwinBee series. He is friends with Dr. Cinnamon, although his naive personality and disconnection from the world often makes him to cause trouble. He is Madoka's grandfather.
He is voiced by Jōji Yanami.
Apparently, Mardock was a peaceful scientist until one day he hit his head upon a pole and ended up trying to take over the world. Whether this insanity is temporary or irreversible is unknown. He loves rabbits, is fairly unhygienic, and lives in a huge mountaintop onto which he has carved a gigantic image of his own likeness. He is Madoka's grandfather.
He is friends with Dr. Cinnamon, although he often causes trouble with his naive personality. He is also known to be a bit perverted, a trait Madoka remarks every time he is seen humming songs.
