The Duke

History
At the age of eight, The Duke is the youngest and smallest of the Freedom Fighters. Jet and the others came across The Duke when they caught him trying to steal food from their camp. According to Jet, the Duke never really had a home, indicating he too was probably orphaned at a very young age by the Fire Nation.

Constant companion to Pipsqueak, the duo originally appeared in the episode "Jet" as guerillas assisting Jet in the fight against the Fire Nation occupation of Gaipan. After Aang, Katara, and Sokka defeated Jet's plan to destroy the village with a flood, the Duke and Pipsqueak lost faith in their once idolized leader and parted ways with the Freedom Fighters. They then traveled through the Earth Kingdom, stealing to eat and struggling to survive. The two eventually came across Hakoda's ship one night and attempted to raid it, but were caught in the act and captured. After hearing their story, Sokka and Katara welcomed Pipsqueak and The Duke to join their makeshift invasion force.

Duke and Pipesqeak are not seen again until the book three episode "The Awakening," where they had joined Sokka, Katara, and Toph in their plan to invade the Fire Nation on the day of a solar eclipse. However the duo does make an appearance in "The Bridge," a canonical interlude comic featured within the second All-Avatar Nick Mag Presents edition. They can briefly be seen playfully mopping up the ship in one scene and donning their Fire Nation outfits in another.
