Oro is depicted as an ancient hermit with thin black hair, golden skin, crimson eyes that glow light blue during battle and is barefoot. His only prominent article of clothing is a large single torn red tarp like cloth, belted with a rope and appears to be like a Kesaya or Chiton like robe draped over his left shoulder and tied at a knot. A magic spell binds one of his arms and he normally fights one-handed, but he can dispel its effects and pull out the other arm at any time.
Unusually for a hermit, Oro has a casual and eased disposition with a lighthearted wile and whimsy. He also possesses a witty insight and a humbling sense of humor and wisdom. His hobbies include touring and leading people through the Amazon, and he enjoys the company of his pets.
Oro's dialogues hint that in his younger days, he was once a devoted and spirited warrior like Ryu, with the pride of a champion akin to Dudley, though his pride also seemed to have got him into trouble, and may be responsible for him becoming a hermit. Oro is also considerably modest, only considering himself a novice of his style.
Oro is not without a sense of justice or a need to humble those extremely proud and boastful of their talents like Urien, the former disciple of Illuminati. In addition, in his conversation before a fight with Akuma, Oro was visibly concerned as to how a violent and disturbingly aggressive individual expressed themselves as the "master of the fist", and was eager to show him how truly distant the path to mastery really was.
Due to his great fighting skills, Oro amazingly enjoys fighting with strong opponents, and finds those lacking exceptional aptitude and refinement boring, though he also does enjoy the simpler comforts of life, and often searches for ways to pass.
Oro has a little weakness for women. When Ibuki fights him as a test to pass her school graduation exam, Oro was disappointed at first because he thought she was asking him to date. His ideal woman is one with an older and mature disposition.
