Pua is a crocodile who appears in The Lion Guard. He is first seen in "The Rise of Makuu".
Background
Physical Appearence
Pua is a severely old, hunched, and winkled Nile Crocodile with mud green scales, a dotted hide, and pale underbelly.
Personality
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, reconizes that fighting isn't always nessecary 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 masindano 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.
Abilities
Strength and Combat: While his strength wasn't as Makuu's, Pua made up for it with greater skills in combat that proves a great battler.
Endurance and Stamina: He was able to take the attacks of Makuu well enough to fight for certain period of time but he was soon exhausted .
Intelligence: He shown to be intelligent as knowing 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 great leadership and giving advice to the Lion Guard to back down.
Leadership Skill: He shown to care for his kind deeply as he promised them to feed them when time is ready but he even shown his kindness to other animals was far too much as Makuu question of his leadership thinking he was afraid of the hippo but knowing the Circle of Life is far more important then anything.
Role in the series
"The Rise of Makuu"
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.
