Mother Wolf, Akela, Father Wolf, Shere Khan (tiger), Mowgli (man-cub), Baloo (bear), and Bagheera (black panther), Colonel Hathi (elephant), Shanti (village girl), Kaa (python), King Louie (king of the Bandar Log monkeys),
From the Book by Rudyard Kipling:
Ikki,the porcupine; Mang,the bat, Chil, the kite, Tabaqui, the jackal, Gray Brother and Mowgli's other wolf brothers.
Also all of the above from the film, except for Shanti, King Louie, and Colonel Hathi. In the book, Mowgli never meets a girl, save his mother. Hathi, while still an elephant, does not control the other elephants (there appear to be only him and his three sons) in a military fashion. The Bandar-Log exsist, but they have no leader, and they are outcasts from the jungle.
