Richard Mardukas

Richard Mardukas is a supporting protagonist in the light novel and anime series Full Metal Panic!. He is a British veteran soldier who serves as a Commander in Mithril and Teletha Testarossa's second-in-command, being an old friend of her family, and has been her father figure since the death of her parents. Basically, he is to Tessa as Andrei Sergeivich Kalinin is to Sousuke Sagara.

He is voiced by Tomomichi Nishimura in the Japanese version of the anime and Andy McAvin in the English version. In the English version of Invisible Victory, he is voiced by Mark Stoddard.

Appearance
Mardkas is a tall, average-looking man with short, black hair and brown eyes. He is about the same age as Kalinin, though unlike him, he has a clean-shaven face. He is normally seen wearing the typical Mithirl uniform, complete with a navy-blue cap on his head.

Personality
Mardukas is generally a dry, straight-laced, and conservative man. He is extremely pragmatic in both military and non-military matters. His pragmatism is the source of much of his reaction towards various other characters. For example, despite being a legendary and highly capable submarine commander himself, he displays great loyalty and dedication towards Tessa and follows all of her naval commands without question due to his acknowledgement of her unmatched ability to command the highly advanced de Danann. On the other hand, he shows questionable respect for Souske due to various unprofessional acts carried out by the sergeant. He also divorced his wife, seemingly without much regret, due to the incongruous nature of his job and married life.

Mardukas has a habit of wearing his cap backwards whenever things get serious. He did this even back when he was in the navy and it was impractical to do so. In fact, his current cap was given to him by Tessa's father, to make wearing one backwards easier. He is also a very calm man, even under extreme pressure; when the Tuatha is ambushed by three high-speed submarines with even faster torpedoes, the crew start panicking, especially because Tessa is off the boat at the moment. Mardukas, however, just wears his hat backwards and proceeds to calmly give orders.
