Appearance
Isaac has bushy brown hair and brown eyes (blue in the anime and 2015 manga). His choice of clothing varies on the occasion.

Personality
Isaac is extremely charismatic and effervescent, spreading happiness to anyone and everyone he and Miria meet without conscious effort. In the process, he and Miria often befriend all manner of unlikely people - including the likes of famed hitman. Ladd Russo and stoic assassin, Chané Laforet. That he and Miria's personalities remain unchanged into the early 2000s is a testament to their indomitable will.

Abilities
Isaac possess true immortality, meaning he cannot age, get sick, be injured, or die via conventional means. Immortality aside, he possess an endlessly large amount of good luck, having escaped numerous dangerous situations throughout the series without serious injury.

Isaac is also fairly competent thief, with his successful theft of the Genoard fortune one of the most significant testaments to their abilities. Isaac's skill at hotwiring automobiles has allowed them to steal multiple cars for their getaways, and they have concocted a special mixture of lime and pepper powder to use as an offensive tool during their heists.
