Wolf cub pack leaders have traditionally taken the names of animal characters from Rudyard Kipling's Jungle Book since the founder of the Boy Scouts Robert Baden Powell approved its moral tone and took it up as a motivational book for the movement. Thus we have:
Akela - the father figure of the wolves; cub-master.
Baloo - the sloth bear; assistant cub-master.
Bagheera - the black panther; assistant cub-master.
