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).

Masaru is one of the few humans able to fight Digimon by himself, though he still count on Agumon's help to fight the stronger opponents. It is also though this reason that Masaru can evoke his DigiSoul by merely connect a punch on an enemy to do it for Agumon to digivolve into GeoGreymon.

When he learn the truth about his father, Masaru's gain a alternate reason for going to the Digital World, to find his father whom, he believe is still alive and bring him home.

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.
