Pua is very patient and slow to anger. Like Mufasa, he is a firm believer in the Circle of Life. Because of this, Pua, like Kion, recognizes that fighting isn't always necessary and that sometimes you must accept defeat as shown when he tells Kion to back down when he doesn't want to fight. He also has great humility as shown when he ignored Makuu's taunts after he was overthrown by him and when he tells Kion that Makuu is stronger than him and won the mashindano that ended his leadership fair and square. All this has made him a wise leader who is held in high esteem to the point where the Royal Family and the Lion Guard had misgivings about the mashindano and felt his successor left much to be desired as shown when Simba tells Makuu "You have very thick skin to fill". before thanking Pua for his leadership.
Pua is a severely old, hunched, and winkled Nile Crocodile with mud green scales, a dotted hide, and pale underbelly.
Animal Strength: While Pua's strength is not as good as Makuu's, Pua made up for it with greater skills in combat.
Expert Combatant: Pua's combat skills are greater than Makuu's.
Animal Stamina: Pua was able to fight Makuu for certain period of time but he was soon exhausted.
Animal Endurance: Pua was able to take the attacks from Makuu.
High-Level Intellect/Leader: Pua is shown to be highly intelligent as he knows eating the fish will cause the problems for the Circle of Life and knowing that Makuu isn't ready for the leadership, but deep down he knew he will learn from his own mistakes to become a great leader and giving advice to the Lion Guard to back down. He is shown to care for his kind deeply as he promised them to feed them when the time is right, but he has even shown his kindness to other animals and was far too much as Makuu question his leadership, thinking he was afraid of the hippo, but he knows the Circle of Life is far more important than anything.
When Pua takes his float to Big Springs, he asks Basi if it's all right for the crocodiles to eat the fish. After Basi politely declines, explaining that there is not enough fish to feed the float, Pua respectfully leaves. However, a young crocodile named Makuu, believing that the float has a right to the fish, challenges him to a mashindano for control over the float. As the animals of the Pride Lands gather to witness the mashindano, Pua and Makuu combat each other, but Makuu is victorious over the aged Pua. Simba comes forward, recognizing Makuu's leadership, and thanks Pua for his service.
Makuu's leadership proves to be malignant in the Pride Lands, however, as he begins wrecking havoc across the lands. Kion seeks Pua to call for another mashindano to reclaim Pua's leadership, but Pua reminds Kion that Makuu is much stronger than him. He then advises Kion to back down if he's not willing to fight Makuu.
Though it seems mostly likely he wanted Makuu to learn his lesson to see how will the Pride Land will go big disaster for not following Circle of Life ways as he will learn huge lesson that another common enemy didn't learn Scar as Mufasa seemed to agreed with Pua to back down.
