One common theme is power exploration. Writers often explore how the stands from Golden Wind interact with powers from other universes. Another theme is friendship. They show how characters from different backgrounds form new bonds.
There's 'Golden Wind Meets the Old Gang'. In this fanfiction, the characters from Golden Wind interact with the previous generation of JoJo characters. It's full of action and nostalgic references. For example, the way they use their stands in different situations is really exciting to read about.
The JoJo manga is mainly in black and white. Colored versions exist but are not the norm. Sometimes, colored illustrations are done for promotional purposes or by fans.
I think it's great. The characters are memorable, the plot is full of twists and turns, and the battles are epic. It's a manga that stands out from the crowd.
