Ono is the quaternary protagonist of the Disney Junior series The Lion Guard. He is one of Kion's friends and a member of the Lion Guard. His position on the team is the keenest of sight. When he becomes vision-impaired, he gives his position to Anga while he becomes the smartest of the team.
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 is quite well-informed in regards to the animals of the Serengeti, and he often states facts out loud for the benefit of his friends. He is very respectful to royalty and is noted to be punctual. 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.
Ono is a narrowly built egret with a very skinny pair of black legs that are striped with orange, which lead to a pair of orange claws. The end of each claw also has a black spot. His upper body is compact, with pure white feathers across the main part of his body. Some pale orange and yellow feathers reach into the end of his wings and form a band around his neck.
High-Level Intellect/Skilled Leader: Ono is the most intelligent member in the entire Lion Guard; as he was able to find ways to make Bunga smell good, knew that Kion was wrong about being unable to move the bees to another location, and many about other animals abilities or behaviors. Though he is proven to not have enough intelligence for good strategy compare to Kion. Ono was also able to help out the Lion Guard, when Kion was (temporarily) was separated to guide them out of a forest when they were lost, but unlike Kion, he doesn't know much of the geography of the Pride Lands.
Eidetic Memory: Ono has a photographic memory; as he can memorize important information like specific details of paintings on cave walls with incredible accuracy.
Skilled Combatant: As a member of the Lion Guard, Ono is a capable combatant. He was able to defeat Mzingo easily by doing a quick dive attack. He even pecked Mwoga on the head repeatedly to keep him away from Fuli.
Flight: As an egret, Ono is able to fly at very high altitudes.
Animal Speed: Ono is the fourth fastest member in the entire Lion Guard; due to him being a flyer. Ono is surpassed only by Fuli, Kion, Makucha, and Anga respectively in terms of physical speed.
Animal Eyesight: Ono has the second best eyesight in the entire Lion Guard; as he is able to see at far distances. In Too Many Termites, he can see through the smallest crack.
Animal Stamina: As an egret, Ono has the third highest stamina in the entire Lion Guard; as proven by Ono who was doing his very best to stay on top of Fuli in the races, as he was using full speed for such a young bird he did many times in the races, but he was proven to be quite exhausted.
Animal Agility: Ono has amazing agility, as he is able to make quick turns.
Ono Spin: Ono originally wanted to learn this special skill of from his biggest hero of the all birds, named Hadithi who made up this skill to make others impression of other animals. Though he wanted to learn this skill more correctly but turns out he made this skill correctly against Janja and his clan.
Blindness: As of "Battle for the Pride Lands", Ono has become (partially) blind after his eyes were exposed to volcanic vog; as a result his vision has become extremely blur, as Ono is no longer the keenest of sight in the entire Lion Guard, as that position was given to Anga; as a result of him (partially) losing his eyesight.
Limited Altitude: Ono's species is not adapted to flying higher than the clouds, unlike vultures or eagles.
Ono, along with Bunga, appears in The Lion Guard's spin-off short series It's UnBungalievable, which involves him and Bunga choosing two animals and deciding which one is better at something.
His specific species is cattle egret (Bubulculus ibis), which is one of the birds with the largest year-round range.
Ono's most common catchphrase "Hapana!" means "Oh no!" in Swahili.
Ono is the only member of Guard who has never sung a solo song.
His primary form of attack is pecking.
It is revealed that Ono has chiroptophobia, which is the fear of bats.
In the beginning of season three, Ono's keen eyesight becomes impaired from an injury.
It is revealed in a flashback in the episode The Lake of Reflection that Kion, Bunga, Beshte and Fuli saved Ono from Janja and his clan shortly before he hatched from his egg while Anga observes from the air, which reveals that he is the youngest member of Kion's Lion Guard.
