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. Even though 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.

Before leaving the Human World to confront Mercurimon, Masaru gained an alternate motive for going to the Digital World: to find his father Suguru who he believes to still be alive and bring him back home. However, the only clue he has about his whereabouts was given by Mercurimon himself, who revealed to be a friend of Suguru and said he set off in search for Yggdrasil, the god of the Digital World in his effort to build a coexistence between humans and digimons.

Masaru only learned anything else about Suguru when he and his friends reached ElDoradimon and learned that the people there has a debt of gratitude with him for helping the city years ago. They swore to protect the city from Kurata's army, but in the end little they could do to prevent ElDoradimon from being destroyed.

Another moment of despair occurred when Tohma, for personal reasons was forced to side with Kurata and he had to fight him. During the battle between ShineGreymon and MirageGaogamon, Masaru's anger triggered the dark digisoul inside himself digivolving his partner to a corrupt and rampaging version of ShineGreymon Burst Mode, after finally stopping him, he returned to a digi-egg state. But did not took long for Agumon to return to life and Masaru bring him to ShineGreymon Burst Mode once again, this time by the right way to fight Belphemon.

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.
