Their troubled sister, Kaori, joined a religious cult. Rising Sun is a founding member of the Japanese equivalent of the Justice League of America, a team called Big Science Action which came together to defend the hero Ultimon from the Monster Army.

He helps save Japan in the Crisis on Infinite Earths, and helps Artemis save her parents, Huntress and Sportsmaster with the help of Infinity Inc.. The Japanese hero volunteers to help the Queen Bee but was brainwashed by her forces and technology. Under her influence he destroys a Neo-Nazi stronghold in Germany, killing many of the people inside. When Justice League members Power Girl and Rocket Red arrive, he attacks them also, believing them to be Nazi loyalists. When defeated, he falls into a coma, all part of a plan. While in a coma, he is taken care of at the Justice League Internationalembassy in Tokyo, Japan. He awakens at the call of the Queen Bee, at the same time as his friends Wild Huntsman and Tuatara, who were also in comas. These two had also attacked Nazi facilities and had fallen into comas when defeated by Justice League members. All three return to duty with the Global Guardians, where they are duly brainwashed. After a few battles with his team, Izumi secretly betrays them and helps fellow Japanese hero Doctor Light battle a horde of Bialyan soldiers. Afterwards, he joins with Doctor Mist, Jack O'Lantern, and Owlwoman together and he helps the three heroes reform the Global Guardians. Fain Y'onia, an ancient enemy of Doctor Mist, targets the team.
