Phoenix Ikki is a bronze saint of Phoenix. Although he was introduced later than the other four main Bronze Saints, Ikki's role in the story is quite significant. He serves as the first antagonist in the series that the other Saints must defeat, as well as a powerful ally later in the series. While Ikki is officially recognized as a Bronze Saint, his base power easily places him well above most Silver Saints, and his reputation as a powerhouse is common knowledge among his peers and fellow Bronze Saints. Even as a child, Ikki was known as the toughest kid of the 100 orphans, and would often defend his delicate younger brother Shun from the other children. He could easily be recognized as the strongest Bronze Saint when it comes to raw power.
Ikki's personality is drastically different from his fellow Saints. He is almost the opposite of his younger brother—Shun is calm, soft, caring and very emotional, whereas Ikki is harsh, cold, aggressive, and very much of a loner. Fellow Saint Wolf Nachi once pointed out that it was very hard to believe Ikki and Shun were related due to the extreme difference in their personalities.
