One thing that really fascinated me about Gohan was his relationships with other characters in the series. We all know that Goku is the main protagonist of Dragon Ball, but Gohan was the one that made more interesting relationships in my opinion.
Piccolo served as a secondary father figure to Gohan throughout the Manga despite them being different species, Krillin became very close to Gohan in the late Saiyan Arc and the Freeza Arc despite Krillin being Goku's best friend, and Vegeta saw another rival in Gohan despite Vegeta being Goku's rival.
Gohan & Videl is the only good romantic relationship in Dragon Ball too.
