Isaac had a neatly combed hair parted to the right, a thin mustache and eyebrows, and a Grecian nose. He wore a sleeveless tunic with linear marking around the collar and one around the lower waist area, a long-sleeved shirt, pants, and shoes.
Like his fellow alliance members, he had an informative personality with extensive knowledge on the Greed Island game.
Greed Island arc
Isaac, alongside Genthru, Nomdieu, Assam, and Nickes try and recruit new players Abengane, Puhat, Biscuit Krueger, Gon, and Killua to Nickes' Alliance. The group manages to convince Puhat and Abengane to join, but fail to convince Gon, Killua, and Biscuit to join for their own respective reasons.
Although a supposed senior member of the alliance group, he and fellow alliance member Nomdieu were left out of a conversation had by Genthru, Assam, and Nickes. It's uncertain if Isaac was at the alliance base when Genthru revealed himself as the Bomber, he along with the rest of the alliance, aside from Abengane and Cuzco all die as the bombs set onto them all detonate simultaneously. Later, Isaac's name is mentioned on Gon's binder, when he looks to see which players are dead or alive.
