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 भेड़िया Nachi once pointed out that it was very hard to believe Ikki and Shun were related due to the extreme difference in their personalities.

As noted द्वारा Kanon in the Poseidon arc and द्वारा Pandora in the Hades chapter, Ikki's Cosmo is unique to him—it is full of hatred, anger, incredible aggression and power, but it was still guided द्वारा his deep प्यार and loyalty for his younger brother, his फ्रेंड्स and loyalty to Athena. Although he dislikes teamwork, he comes to battle whenever Athena's Saints need his help, and is often seen coming in the nick of time to save his younger brother and फ्रेंड्स from certain death. This tactic has always been exploited to their advantage, since the enemies are caught द्वारा surprise upon meeting/fighting him. He is a noble, complex and mature character, who does not doubt whenever it's necessary to sacrifice his life for his friends.
