Sokka was one of the main characters of Avatar: The Last Airbender on Nickelodeon. He was pretty funny.
He was pretty much the only one in the group who couldn’t bend any element. Something that he is frustrated about later in the series.
His best moments was for comic relief.
He did have a romance with Suki, which was OK.
He does become better at swordsmanship, under the guidance of a sword master in the Fire Nation who doesn’t judge him because he is from the Water Tribe.
He manages to survive the whole global war. Which wasn’t too surprising.
