I really like 'Croc's Choice'. It's a short but impactful fanfic. In it, Killer Croc has to choose between following his old criminal ways or helping Batman to stop a new threat to Gotham. The author does a great job of showing the internal struggle within Croc. He's not just a mindless monster, but a character with his own thoughts and emotions.
To create a believable character arc for Killer Croc, start with his backstory. Show his early life and how he became the way he is. Maybe he was once an ordinary person who was experimented on. Then, as the story progresses, have him face challenges that force him to change. For example, if he meets a group that accepts him, he might start to become more trusting. By the end, he could be on his way to becoming a more heroic figure, or at least less of a feared outcast.
It could be a really dark and intense story. Killer Croc is a menacing character and paired with the Joker, it's bound to be full of chaos. Maybe it explores their relationship, like whether they are allies or enemies in this graphic novel.
One great fanfic could be 'The Redemption of Killer Croc'. In this, Killer Croc is shown as more than just a brute. Batman tries to understand his past traumas that led him to become the way he is. It delves into Croc's early life, how he was bullied for his appearance and how that rage turned him into a criminal. Batman, instead of just fighting him, offers a chance at redemption, which creates a very interesting dynamic between the two characters.
Killer Croc was born Waylon Jones with a rare skin condition that made him look reptilian. He was bullied and ostracized, leading him to a life of crime.
Well, Killer Croc in Batman Arkham City has a rather interesting story. He's been in Arkham City, making the sewers his domain. His story is intertwined with the overall dark and gritty atmosphere of the game. He's a formidable foe for Batman. Croc's backstory of how he became this monstrous being adds depth to his character in the game. His encounters with Batman are intense, with Croc using his physical prowess and the environment of the sewers to his advantage. Batman has to use his wits and combat skills to deal with Croc.
His origin story is also a common theme. Writers might expand on it, change certain elements, or explore how his past traumas have shaped him into the character he is. For example, they could delve deeper into his genetic mutation and how it affected his life growing up, his family's reaction, and how that led to his life of crime in Gotham.
In Batman fanfiction involving Killer Croc, their relationship is often complex. Killer Croc is a formidable foe for Batman. He represents a more bestial and primal threat compared to some of Batman's other villains. Their encounters can be really intense. Batman has to use his wits and combat skills to deal with Croc's brute strength. Fanfiction might explore how Batman tries to rehabilitate Croc at times or just keep him in check in Gotham's sewers where Croc often lurks.
To develop their relationship, focus on their differences. The OC might be a symbol of normalcy while Killer Croc is an outcast. Have the OC slowly accept Killer Croc's differences and vice versa. They could also have shared interests, like a love for a certain part of the sewers where Killer Croc lives. By exploring these shared interests and respecting their differences, their relationship can grow. For instance, the OC could decorate Killer Croc's lair with things from the surface world that he secretly likes.
The combination of Killer Croc and the Joker. These two characters have very distinct personalities and powers. When put together, they create a unique and unpredictable story.
