Suki

 Suki was the eldest member and leader of the all-female Kyoshi Warriors of the Earth Kingdom's Kyoshi Island. Having begun her training when she was only eight years old, Suki was well-respected by her fellow warriors for her leadership and combat skills. When Team Avatar arrived on Kyoshi Island, Suki and a few other Kyoshi Warriors captured them, thinking they were Fire Nation spies. Later, after realizing Aang was the Avatar, they released and befriended them, with Suki in particular forming a bond with Sokka.
