Saint Seiya POP! Animation figurine Gold Leo Ikki 9 cm

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 Andromeda 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 than his fellow bronze saints. He is very unlike his younger brother - who is almost the opposite of him: Shun is calm, soft, caring and very emotional, whereas Ikki is harsh, cold, aggressive, and very much of a loner. Fellow bronze 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.

As noted by Kanon in the Poseidon arc and by Pandora in the Hades chapter, Ikki's cosmos is unique to him -- it is a cosmos full of hate, anger, and incredible aggression and power, but guided by his love for his younger brother, his friends and Athena. Although he dislikes working in groups, 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 from certain death.This tactic has always been exploited to their advantage, since the enemies are caught by surprise upon meeting/fighting him. He is a noble character, mature, and that does not doubt whenever it's necessary to sacrifice his life for his friends. Ikki is a complex character, very rich in nuances.
