Max

Max (マックス) is one of the primary protagonists of Level 1 Demon Lord and One Room Hero manga and anime series. He was once a heroic warrior responsible for the downfall of a powerful Demon Lord, though in the ten years since, he has slacked off. With Maou's return, the Demon Lord has moved in along with his assistant, Zenia, in an effort to get his old rival back into fighting shape.

Appearance
Ten years before the defeat of the powerful Demon Lord, Max was a young warrior with black hair and eyes, and a well defined muscular build. At the time, his clothing consisted mostly of his warrior suit, equipped with several pieces of armor, a pair of jeans with knee-length armor, and a red bandana that he wore around his forehead.

Accused and criticized by the public following the defeat of the Demon Lord, due to his misguided actions, Max resigned from his title as a hero and got rid of all his old gear, except for the Blazebringer sword. His current clothing consisting of a plain white t-shirt, a pair of jeans, and some sandals.

Despite being a slacker for many years, he's still maintained most of his muscular physique, and he's apparently grown quite a bit of a moustache.

History
In his past Max was once a brave man, and a formidable warrior, with an unimaginable will and sense of justice. Who eventually came to be known as the legendary hero who defeated the powerful Demon Lord.

Although this victory of his saved the whole world, because of the scandals he ended up causing later, Max was forced to leave his position as a great hero. Which ultimately made him lead a self-indulgent life ever since, in the hope that he would be able to stay out of society as much as possible.
