Ono is described as an intellectual and brainy egret. He never hesitates to take to the air and seek out animals in help, and will sometimes act even before Kion asks him to. Ono is loyal to Kion and rarely questions his leader. Despite his sharp social skills and optimism, Ono is exceptionally blunt and able to lay out his feelings without any sugar-coating. He is by far the most down-to-earth member of the Lion Guard, always thinking things through before jumping in. Perhaps this is in part because of his keen eye and ability to step back and assess before taking action. His intellect is sharp, and he has the cleverness and patience to act on it. Ono is brave and has a knack for following the rules. His principles are clear in his willingness to fight with his full heart for the Circle of Life, and he is a valued member of the Lion Guard for his intelligence and ability to see things from afar.

Ono isn't afraid to show his annoyance to other animals and is also very reserved. Ono's value to the Lion Guard doesn't get to his ego, but it does make him a workaholic, as revealed when he tries to continue flying after he's temporarily hurt his eye.
