Colonel Tusker is shown to be the leader of a herd of Phan Phan, and he runs the herd similarly to a military squadron. Every day from dawn, Tusker has his unwilling herd march all over the Dream Land. However, his strict orders and constant marching sometimes cause members to consider a "transfer to another herd". Tusker also has a mate called Westley and a calf called Tula, with both appearing to be part of the army.
Tusker is portrayed as a pompous, buffoonish, stereotypical British soldier who is not too bright. Tusker can be petty at times, criticizing one elephant for having dust in his trunk and another for smiling too widely. He also refuses to help search for Mowgli as it would interfere with his marching. He believes himself to have an excellent memory, despite his frequent forgetfulness. Later on he is destructive, crushing trees the second time he and the Quintet of Phan Phan sing their song again. However, despite his strict orders he seems quite charismatic and gets command of the Quintet of Phan Phan.
