Makucha is a stocky, well-built leopard with incredible agility and physical strength. His fur is a pale lemon color, and his rosettes are brown outlined with black. The spots on his face and neck are smaller and solid colored. His sclerae are dark yellow, with his irises being green. His inner ears are light pink, rimmed with black and a single rosette on the back of each. Half of his long tail is banded in white, and his underbelly and paws are white in color. He has thick, bushy dark brown eyebrows, long black whiskers, black claws, white teeth, and a black nose. His paw pads are red-brown.
Makucha is a very persistent and territorial character. He is a ruthless predator and will not relent until he is successful in killing his quarry. He is confident in his jumping abilities, as proved when he jumped over Big Ravine without hesitating. When confronted, he is fierce and willing to fight, but also employs a cocky casualness. He is very confident in his fighting skills, believing himself capable of taking on two at once. Despite his confidence, however, he is not arrogant or foolish: If he is severely outnumbered or overpowered, he will back down. Makucha has a great liking for okapis as food, and will go to great lengths to catch one. He frequently roars and growls to express anger or irritation.
When he feels that someone has wronged him, he can be severely vengeful. With these individuals in particular, he becomes incredibly uncompromising, and refuses to accept peace when offered to him. When an enemy encounters him on his home turf, he is fully capable of working in a team, and using their numbers to even out the odds.
Makucha chases Ajabu all the way into the Pride Lands, trying to catch him. Ono spots him stalking gazelles, and the Lion Guard confronts him. They demand that he leaves, to which he responds that they will have to make him. He flees, and is immediately pursued by the team. However, he is able to evade them by leaping over Big Ravine. He laughs before bounding away.
Makucha later spots Ajabu as he speaks with Thurston. He issues a low growl and murmurs, "Look who's here." He steps into a crouch and slowly approaches his intended prey. A surprised Ajabu remarks that he cannot believe Makucha followed him so far, and Makucha replies telling Ajabu that because okapis are rare, they are to be persistently tracked until they are caught. After informing Ajabu that his trail is about to come to an end, he moves forward, but his progress is impeded when Thurston runs into him in a panic and bowls him over. As he strains to rise, Thurston requests that Makucha does not eat him. As he frees himself, Makucha roars and pushes Thurston away with a hind paw and responds that he is after something far tastier, to Thurston's resentment.
While chasing Ajabu, Makucha passes by the Lion Guard. As the two run farther, Ajabu demands that Makucha leave him alone while he flees. Makucha insists that he will not, having chased Ajabu for so long. He springs with a snarl, but is kicked back by Ajabu's hind hoof. He bounces once with a grunt before coming to a halt, dust clouding around him. He sits up and pants before announcing that Ajabu is just making him mad. He resumes the pursuit, exclaiming that he has Ajabu when the okapi trips and falls.
However, as he charges, Beshte lifts him up with his muzzle and flings him away. Once again, he gives a grunt as he bounces once before landing on his side. Inhaling deeply, he rises with a shake of his head and asks the Lion Guard why they do not mind their own business. He comments that he is simply greeting a friend, to which Fuli replies that he was not behaving in a friendly manner. With a flick of his tail and a turn of his head, Makucha responds that leopards say hello using their teeth. He rolls his eyes and asks "So what?"
Kion tells Makucha that it is time to say good-bye, and he fiercely responds that he can fight two at once. He roars as Bunga grabs his tail, swiveling his head to glare at the honey badger. Makucha turns his body until he is facing Bunga, and, lifting his tail with Bunga still gripping it, expresses the hope that Bunga will taste better than he smells. He is forced to duck when Ono dives for him, but after a moment, he approaches Kion and Fuli, quietly growling and dragging Bunga along. He bares his teeth at the two felines, but surrenders when Beshte bellows at him. He declares that the Lion Guard can have it their way, adding that even an okapi is not worth so much trouble. He turns away and breaks into a run before bounding out of sight.
Makucha appears when the Lion Guard are passing through his territory in the Back Lands. He tries to drive them off, but, after a fight, he reluctantly allows the Lion Guard to pass through his territory but to make it quick.
Later, when the Lion Guard is trying to get rid of a dam that is blocking the watering hole for Dhahabu's herd, and he reveals that they are in his territory once again, and he has brought reinforcements. The Lion Guard manages to fend off each of Makucha's fellow leopards, but Makucha threatens to eat Dhahabu if they get any closer to the waterhole.
Bunga tries to offer himself in Dhahabu's place, but Makucha isn't interested. With a little encouragement from the Lion Guard Dhahabu realizing what she must do, so she kicks Makucha knocking him at the dam. The impact from his hit causes the dam to break, causing Makucha to make a hasty retreat.
When Fuli and Makini escort the wise tortoiseKongwe across the Back Lands, Makucha notices their presence from a tree branch and he approaches them, assuring them that they're always 'welcome', especially the tortoise. Makini mistakes his words for friendly banter and attempts to introduce herself, before Makucha reveals his true intentions. Fuli steps between the leopard and her two associates, warning him away. Makucha succumbs to her wishes, but warns her that she's in his territory.
Later, Makucha leaps out in front of the tortoise and mandrill. Once again, Fuli stands between him and the other two animals, but this time, Fuli chases Makucha away, until he climbs up a tree. Fuli sinks her claws into the tree, but is unable to follow the leopard, or remove her claws. With Fuli trapped, Makucha approaches Kongwe, who hides in her shell. Makini distracts Makucha briefly with some performance moves, but Makucha bats her away. He tells her that she's lucky he doesn't like mandrill, just before Fuli tackles him again. Makucha proceeds to run away, performing a zigzag movement which Fuli cannot keep up with.
The leopard decides to rest for a while, when suddenly Fuli approaches him, asking him for round 2. Makucha is pretty certain that number is higher, but gladly accepts her challenge. He speeds on ahead with confidence, until the cheetah tackles him, pinning his body to the ground. Shocked, Makucha decides that his taste for tortoise has gone. But when Fuli suggests that her taste for leopard is still there, Makucha laughs nervously, before retreating.
