• Mowgli (voiced by Emma Tate in seasons 1–2 and Sarah Natochenny in season 3) is a human boy raised by wolves in the jungle, as the adoptive son of Daruka and Raksha, and the brother of Lali and Bala.

• Bagheera (voiced by Sam Gold in seasons 1–2 and Abe Goldfarb in season 3) is a black panther. He is Mowgli's best friend. Unlike most other adaptations (like Disney's 1967 film), Bagheera is not as wise or strict as in the book. Most animals in the jungle never dare to step in the way of the panther. He often fights Shere Khan to save Mowgli.
• Baloo (voiced by Jimmy Hibbert in seasons 1–2 and David Wills in season 3) is a sloth bear In the series, he is bipedal, wears glasses and he is Mowgli's mentor. Baloo likes to tell stories of the jungle.
• Kaa (voiced by Joseph J. Terry in seasons 1–2, Billy Bob Thompson in season 3) is an Indian python who is sort of friends with Mowgli, Bagheera, and Baloo, yet moody and feared.

• Raksha is the adopted mother of Mowgli. She is patient and motherly, but can be stern when necessary.
• Lali is the daughter of Daruka and Raksha. She is sweet, and caring, like her mother, but can be extremely protective and rebellious. Her grandfather is Akela.
• Bala is the son of Daruka and Raksha. He is a brave and loyal, but competitive wolf, who often gets in trouble. His grandfather is Akela.

Villains

• Shere Khan (voiced by David Holt in seasons 1–2 and Marc Thompson in season 3) is a Bengal tiger who is the main antagonist of the series. He's territorial and going to kill and eat Mowgli, but often fails in his attempts. He has a scar on his left eye. Shere Khan lost one of his claws in an earlier fight with Mowgli who keeps the claw as a pendant.
• Tabaqui (voiced by Nigel Pilkington in seasons 1–2) is an Indian jackal. He is Shere Khan's sycophantic, greedy, devious sidekick where he lacks the courage to disagree with his tiger master. He is usually the one to set up traps for Mowgli so Shere Khan can eat him.
• Bandar-log are a group of langurs who like to cause trouble for Mowgli and his friends. They live in the Cold Lair temple ruins.

• Phaona (voiced by Aaron Albertus in seasons 1–2) is an Indian wolf who is the grandson of Akela.
