Defining Bo-bobo's personality can be somewhat difficult. He is an unpredictable person, not even his allies are aware of what he will do next. However, when he is not involved with one of his antics, he manages to retain a semi-serious composure, though he is very sensitive; even the slightest put-down can make him depressive. Bo-bobo's personality becomes increasingly more serious when he is faced with strong opponents. Bo-bobo's offense is a technique called Super Fist of the Nose Hair.
