Masaru Daimon (大門　大 Daimon Masaru) is a fictional character in the anime series Digimon Savers. He is voiced by Soichiro Hoshi for the Japanese version.

Masaru is a 14 year old student and loves fighting. Masaru lives with his mother and younger sister. He meets and fights Agumon in the first episode of the series. Agumon agrees to become his partner and soon Masaru becomes a member of DATS. As Masaru's partner, Agumon will do anything for him and refers to him as his "aniki" (兄貴, a Japanese colloquialism for "older brother," used in this case with the connotation of "boss" as seen in the Yakuza).

Trivia

 * According to the first episode, his birthday is the same day as the one on which Digimon Savers started in Japan, April 2nd.
 * Masaru is the first human lead character of any Digimon series (anime as well as manga) that doesn't wear goggles.
 * His name is probably also an intended pun as it could be read Daimon Dai while daimondai means "big problem", which would make sense given his love for fighting.
 * Practically the only human able to fight Digimons by himself, as he must count with Agumon's help to fight stronger opponents.
 * Despite his partners Tohma and Yoshino are able to bring out their digisouls by themselves to evolve their partners, for some reason he must connect a punch on an enemy to do it. Despite he must do this process to evolve Agumon to GeoGreymon, later episodes reveal he doesn't need to repeat it to evolve him to his perfect form, RiseGreymon.
 * Masaru Suguru, Daimon's father was a lead researcher of the Digital World and even lead an expedition there 10 years ago, but did not return and is missing since then. After learning the truth, Daimon believes his father may still be alive, and swore to find him and bring him back.
