One common theme is self - sacrifice. Altruistic warriors often put their own lives on the line for the well - being of others. For example, in many war - related novels, soldiers sacrifice themselves to save their comrades or civilians.
Sure. 'The Three Musketeers' can be considered as one. The musketeers are like altruistic warriors. They fight for justice, protect the weak and uphold honor. They are always ready to put themselves in danger for the greater good.
My knowledge ends in 2021. However, if you are referring to the novel Rebirth Warrior, I can tell you that it has yet to debut. Rebirth Warrior was a very popular fantasy novel that had been published in digital and comic versions on multiple platforms, but it had yet to be adapted into a television series or movie.
Well, the story often portrays the hardships and obstacles faced while trying to find this altruistic man. It might include unexpected turns and lessons along the way.
