Mwoga has dark feathers with lighter gray tips at the tip of his wings. He bears a bald head, thin legs, and a large dark yellow beak with a red tip and a chip at the end. He has a few black hairs on his head, and black bushy eyebrows. His neck and face are a dull pink, and is covered in wrinkles. He also has a fluffy white neck ruff, and his claws are dark yellow with black claws.
Mwoga is a rather foolish vulture. Despite this, he is able to intimidate members of his flock. He is sneaky and devious, and is willing to jump at the opportunity to take advantage of a weakness in the Lion Guard. He also is somewhat of a coward and prefers to attack only if his prey is unable to fight back. He takes orders from Mzingo without fail, although is open to questioning him.
Mwoga is first seen bumping into Ono, whose left eye has been wounded. He is slightly annoyed at this, though becomes inquisitive when he finds out just who Ono is. He returns back to the Outlands, and Mwoga is seen being permitted to join the committee current procedure. When Mzingo says that he hopes Mwoga has a good reason for being late, Mwoga responds that he indeed does. He then reports to Mzingo that a member of the Lion Guard, Ono, cannot see out of one eye. Mzingo is interested by this, and decides to study the situation.
Mwoga in seen in a dead tree with the other members of Mzingo's Committee. After singing the parliamentary anthem, Mwoga spots Fuli lying down below them, and he comments that he hasn't ever seen Fuli when she wasn't running. He asks what's wrong with her, and Mzingo answers that it appears Fuli did not know her limits. He has Mzingo confirm that what Fuli doesn't know is that cheetahs can't run for too long without a rest. Mzingo tells him that since Fuli has no energy, she can't fight back. Mwoga asks if a subcommittee should be formed to discuss attacking Fuli in her weakened state, but Mzingo tells him that this is the one time that they will not follow parliamentary procedure and attack right away.
The vultures gather around Fuli, who orders them to back off and warns them that they don't won't any part of her. Mzingo replies that they do, and Mwoga adds that he wants a leg. When Mzingo tells Fuli that she can't fight back due to her low energy, Mwoga questions whether or not she can. Mzingo assures him that she cannot and asks who is in favor of attacking from all sides. Mwoga agrees, along with the rest of the flock.
However, when the vultures attack Fuli, they are stopped by the Lion Guard. Ono attacks Mzingo, pecking him on the head repeatedly while Mwoga cries out in pain. He is then blown away by Kion's Roar.
Mwoga, Mzingo and another vulture circle around a Baby Baboon and soon give chase. After a vote, they swoop down to attack, but Mwoga is halted by Ono, who flies up to greet him. When his leader is stopped by Beshte, the vultures yield to the Guard and fly away.
A bit later, they start to circle again, with Mzingo having sworn that he saw their target from earlier. Once they hear the Baby Baboon's cry, they settle on a nearby withered tree, watching the tall grass blades intently. When Fuli pops her head above the grass, Mwoga questions if she's all alone. She explains that she's hunting, and hints towards her prey being Mzingo. He quickly calls for his Committee to leave.
Mwoga returns with his two fellow vultures when Fuli delivers the Baby Baboon to his mother. They swoop down to attack, but are thrown off course when the baboons fight back by throwing fruit at them. Mwoga collides heads with the other vulture and plummets to the ground. A short while later, he is back in the air, and follows Mzingo's commands by aiming for the Baby Baboon whilst he deals with Fuli. Mzingo meets his match and is pinned by Fuli, and calls to Mwoga and the other vulture to cease their actions. Mwoga questions his leader as to whether or not they should have a vote, but Mzingo is adamant that they leave immediately. Mwoga obeys him and the trio fly away.
Mwoga flies behind a harrier hawk in silence, until she confronts him on his actions. He informs her that he is indeed following her, since hawks are such great hunters and he was hoping to enjoy the leftovers. The hawk seems humbled by his comment, and allows him to follow, introducing herself to him as Mpishi. After introducing himself, Mwoga asks her why she's in the Pride Lands' territory. Mpishi speaks of how she has been trying to get a meal, and how the Lion Guard keep foiling her plans. Mwoga seems hesitant to believe she can get food if the Lion Guard are keeping an eye on her, but she believes she just needs to team up with someone, and offers Mwoga a fresh meal. Mwoga rejects this, claiming carrion is the only meal for him, which offends Mpishi. The two then share their idea of a perfect meal, and Mpish offers Mwoga a deal - if he helps her get a meal, he gets all the leftovers. Although hesitant to take up a deal without the committee's permission, he is eventually persuaded and agrees to go ahead.
Later, Mpishi grabs a baby hamerkop, but is pursued by Ono and Kulinda, the baby's mother. When ordered to let the baby go, she relents by throwing the baby behind them, where Mwoga catches the baby with his beak. He flies away, but does not see Bunga climb a tree just ahead of him. As he passes, the honey badger leaps onto his back, dragging him down. Mwoga quickly passes the hatchling back to Mpishi as she passes, eventually slamming into the ground. When he looks up, the Lion Guard have arrived, and Mwoga decides that it's time to head back to the Outlands.
