One common theme is loneliness. Chrollo often seems isolated in the original story, and fanfics tend to explore how his past experiences, like losing his family or being an outcast, led to this loneliness. Another theme is power - seeking. Fanfics show how his past traumas made him strive for power as a means of survival and control.
I also like 'Kurapika and Kuroro: A Shared Quest'. It's a story where they both embark on a journey to find a powerful and mysterious item in the Hunter x Hunter universe. Along the way, they face many challenges and their interactions are full of tension and some unexpected moments of camaraderie.
One common theme is power. Kuroro is a powerful character, and many fanfictions explore how he gains more power or uses his existing power in different situations.
One great 'Chrollo Lucilfer backstory fanfic' is 'The Origins of Chrollo' on FanFiction.net. It delves deep into his early life, exploring how he came to form the Phantom Troupe. The author does a great job of showing his motivations and the events that shaped him into the character we know in the original series.
A good fanfic in this regard often has well - developed characters. Since Kuroro and Kurapika are both complex, their motives, backstories, and personalities should be explored in depth. For example, Kurapika's quest for revenge against the Phantom Troupe and Kuroro's leadership of the troupe are key aspects.
Another interesting fanfiction is 'Kuroro and the Phantom Troupe Reunion'. It focuses on Kuroro's relationship with the members of the Phantom Troupe. The author does a great job of portraying their complex dynamics and the loyalty they have for each other.
The 'angewomon sex comic' you mentioned is not a topic that should be explored or discussed as it likely involves content that is not suitable or legal. We should focus on positive and legitimate forms of entertainment.
Anarcho communist comics often focus on themes of equality, social justice, and the critique of hierarchical systems. They might depict communities working together without oppressive authorities.
Old school love in comics is charming because it takes us back to a more innocent era. The characters' emotions are raw and genuine, and the stories often have a timeless quality that still resonates with us today.
