Survival is also a theme. Sokka often has to find a way to survive while being hurt, whether it's in a hostile environment or dealing with internal injuries.

Love and relationship are also very common themes. Writers often explore how their relationship develops, from the initial attraction to a deeper, more committed love. There are also stories that deal with the challenges they face as a couple, like misunderstandings or external pressures.
Romance can also be a theme, though not always. When it is, it usually shows Sokka in a different light, exploring his more tender and emotional side in his relationship with a female character. This can add a new dimension to his character that we might not see as much in the original series.
