Haohmaru
覇王丸
Haohmaru is the star character of the series and is one of the series' most known characters (the other being Nakoruru). He is introduced in Samurai Shodown and continues to appear in every title of the series. His character origin was originally based around the famed swordsman, Miyamoto Musashi, a duelist who claimed to have never lost a match. He is visually modeled after Hyakkimaru from the manga, Dororo. Though he is a swordsman with no loyalties to any lord, Haohmaru has a "samurai spirit" which is often stressed in the series. He is also often accredited to defeating most of the series' villains.
In Gamest's 1997 Heroes Collection, Haohmaru was tied with Ukyo for 29th (out of 50) of the staff's favorite character rank. He was also voted as the second favorite character by the development team and fans in Samurai Shodown II. According to the Q&A page for Neo Geo Battle Coliseum, developers admitted that no matter what the fans wanted, they wanted to include Samurai Shodown characters and made Haohmaru's inclusion one of their top priorities in development. He also makes regular appearances in the series' merchandise and has at least two action figures.
Story
At the age of fifteen, he challenged Jubei to a duel but lost due to lack of experience. Jubei, amused by the youth's bravado, brought Haohmaru to Nicotine so that he may gain proper training. Whilst living there, he also met and befriended Genjuro, fellow student and another orphan like himself.
Orphaned, Nicotine Caffeine spotted him and took him under his tutelage along with Haohmaru in his home. Both students were close friends yet Genjuro's hunger for power worried Nicotine. To test his students, he tempted them to fight over the treasured sword, Fugudoku. They were tested by facing off with a group of other fighters. In contrast to his friend, Haohmaru fought only until his opponent lost the will to fight and didn't give chase. After Genjuro left Nicotine's home, Haohmaru was rewarded with the sword. Encouraged by his master to further improve himself, Haohmaru travels the lands perfecting his sword skills, and searches for worthy challengers in the name of Shura.
During his many travels, Haohmaru trains Shizumaru and inspires Takechiyo. He guided both until he felt they had matured enough before continuing his journey. He will sometimes challenge them to a duel after a certain amount of time to test their skill and resolve.
