In these fanfictions, the theme of family legacy is prominent. Draco has the burden of the Malfoy name, and how he deals with that in relation to Harry is explored. Another theme is the struggle between good and evil. Even though Draco was initially on the 'evil' side, fanfictions often blur the lines and show that he may not be all bad. And the theme of self - discovery is also there. Both Draco and Harry learn more about themselves through their interactions in the fanfictions, which can be really fascinating.

And of course, the theme of friendship itself, how it develops in spite of their initial enmity, and how it changes them both for the better.
Another theme is the exploration of complex relationships. Since they were enemies in the original series, in mature fanfiction, their relationship becomes more than just hatred.
