Mzingo's Parliament is a flock of vultures that live in the Pride Lands and the Outlands. They are allies with Janja's Clan, but are shown to be more sophisticated than the hyenas, choosing to vote on and study situations before taking action. They work in a Parliament, and often form subcommittees to focus on situations before taking action.
The flock is seen gathered on a tree, when they are suddenly interrupted by Mwoga, who is late to an in-progress meeting. Mzingo offers up a vote to allow Mwoga to join the meeting, and his fellow vultures agree, and Mwoga settles next to a fellow member. When Mzingo asks if Mwoga had a good reason for being late, Mwoga replies that he discovered that Ono of the Lion Guard had lost sight from one of his eyes. Mzingo and his flock decide to keep an eye on the situation and consider a sub-committee to deal with the issue. After a unanimous vote, they agree, before shifting the conversation to other matters.
Mzingo's committee appears perched in a dead tree. Before calling their meeting to order, they first chose to sing their anthem, All Hail the Vultures. Once they are finished, Mwoga notices the worn-out Fuli resting not far from them. Mwoga suggests forming a subcommittee to assess their options, but Mzingo decides to simply attack her without the usual procedures.
The vultures land and taunt the cheetah. When Mwoga double checks with his leader on her physical state, Mzingo informs him that she has overexerted herself and is thus harmless. As per a parliamentary vote, they then move forward to attack, promising her that it will be over quickly. Nearby, Ono sees Fuli in danger. The Guard rushes to her aid, with Kion pushing Mzingo out of the way, Bunga attacking another vulture and Ono taking care of Mwoga. As another pair are about to strike the fallen cheetah, Beshte charges in and knocks them away. Mzingo calls for his group to reconvene, and Kion steps forward. He warns the vultures that when you mess with one member of the Guard, you mess with the whole Guard. He then uses the Roar of the Elders to blast the birds away.
Mzingo, Mwoga and another member of the committee are first seen chasing after a Baby Baboon. When they dive into action, the Lion Guard arrive just in time to frighten the vultures away, having seen them circling the baboon just before the attack. Once safe, the Guard task Fuli with getting him home.
Fuli later meets up with the same three vultures while on her way to Mapango Cliffs. Mzingo comments that he saw the Baby Baboon somewhere nearby, but he only becomes certain when the Baby Baboon accidentally steps on a stick. As Mzingo and his committee settle to investigate nearby, Fuli announces that she has an idea. Part of the grass begins to shake, and Mzingo gets excited. His excitement vanishes when Fuli pops her head out. He questions where the Baby Baboon is that he was trying to 'help', and she responds by telling him that the Baby Baboon has likely gone home and that she's busy hunting, though Mzingo is still visibly suspicious. He asks her what she is hunting, and she replies that Mzingo himself is looking rather plump. The vulture hurriedly flies away with the rest of his Committee, leaving the path open again.
But just as she reaches the cliffs and the Baby Baboon reaches his mother, the vultures appear again. They dive towards the Baby Baboon and his mother with Mzingo exclaiming that Fuli can't climb faster than they can fly. He is soon hit by a flying fruit, since entire troop is throwing fruit towards them. This causes Mwoga and the other vulture to crash into one another. Mzingo instructs Mwoga and the other vulture to go for the baby, whilst he takes care of Fuli. He dives towards her and she swipes back, but Fuli slips at the edge of her rock. She manages to grab hold of the side. Before Mzingo can strike her, Baby Baboon hits him with a fruit, which knocks him down. He becomes briefly entangled in a tree branch hanging over the cliff, but soon regains his posture. He flies upwards but Fuli leaps towards him, pinning him to the ground. She orders Mzingo to call off his committee and he does so, flying away with them.
Mwoga is a member of the flock. He appears to be somewhat unpopular among the other members, perhaps due to his foolish ways. Despite this, he is shown to be both sly and fierce, making him a valuable member of the flock.
