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 to fight. He lives with his mother and younger sister Chika. Masaru meets and fights Agumon in the first episode of the series. When the fight ends in a draw Agumon agrees to become his partner. Soon afterwards he's recruited as a member of DATS. As Masaru's partner, Agumon idolizes 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 counts on Agumon's help to fight the stronger opponents. Despite other humans can evoke their digisouls by themselves, Masaru must connect a punch on an enemy to do so, subsequently using it to digivolve Agumon.

When he learned the truth about his father, Masaru gained an alternate motive for going to the Digital World: to find his father who he believes is still alive and bring him home. However, though he wasn't able to fulfill that goal when he was forced to return to the real world, he learned that Mercurimon knew his father.

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. Masaru is also the first human to hurt a digimon on a regular basis.
 * 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.
 * He appears in the game Digimon World DS, in a quest.
