Masaru Daimon (大門　大 Daimon Masaru) is a fictional character in the anime series Digimon Savers. He is a 14 year old student and loves fights, frequently challenging virtual strangers. He meets and defeats Agumon in the first episode of the series. Agumon afterwards agrees to become his partner. Later, Masaru becomes a member of DATS. His father, Suguru Daimon, was the leading authority of Digimon research until he disappeared ten years ago. He lives with his mother and kid sister. He is voiced by Soichiro Hoshi for the Japanese version.

Trivia

 * 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. He is also the first Digimon anime leader whose name doesn't start with Ta/Da. He does follow the latter tradition in a way though by having his name written as　大, which (a) also has the readings Dai and Tai, (b) is also the first character in Daisuke's given name and (c) the kanji of which the first character (太) in Tai's name was derived from, also sharing the same basic meaning (big).
 * His name is probably also an intended pun as it could be read Daimon Dai while daimondai (大問題) means "big problem", which would make sense given his love for fighting.
