Commander Richard Sampson

Commander Richard Sampson, known in the Japanese version as Captain Rentarou Satsuma (薩摩 廉太郎) is Marcus Damon (Masaru Daimon), Thomas H. Norstein (Tohma H. Norstein), and Yoshino "Yoshi" Fujieda's superior officer, responsible for giving them orders and supervising all operations from the base. More often than not, his purpose was to delegate to his subordinates from the command center. However, when Akihiro Kurata's machinations led to his team being dissolved, he was arrested. Presumably broken out by his digimon partner, Kudamon, he rejoined his team. When they resolved to try and enter the Digital World, Sampson and Kudamon were forced to remain behind, and hold off the three mysterious beings known as Kouki, Ivan, and Nanami, who had the power to turn into Digimon. Sampson and Kudamon battled them, and were last seen in an explosion. The two later return in Episode 41, with Kudamon being able to Digivolve into Sleipmon.

Before the start of the series, Sampson was a private investigator who worked with Hiroshi Yushima. After investigating multiple missing persons cases, they came to learn that the disappearances were the result of the opening of numerous gates that led to the strange realm known as the Digital World. Sampson and Yushima joined an expedition into the Digital World, where they came to know Marcus's father, Suguru. However, they were forced to return to the Human World without him. After this, Suguru somehow managed to send something to the human world - Sampson and Yushima's partners, Kudamon and Kamemon, as well as the data for the Digivice. Sampson then became the Captain of the Japanese branch of DATS.
