To develop Mr Dark, you could give him a more complex backstory. Perhaps he was once an outcast in the Glade of Dreams and his evil actions are a form of revenge against those who wronged him. You can also show his relationships with other characters in a new light. For instance, he could have a begrudging respect for Rayman's tenacity and this could create some internal conflict within him. Also, his appearance could be changed or enhanced in the fanfiction to reflect his evolving character. For example, if he starts to have some good in him, his dark and menacing look could start to fade slightly.
One way to develop Mr Dark is to explore his motives more deeply. For example, is he truly evil just for the sake of being evil? Or does he have some underlying insecurities or desires that drive his actions? Another aspect could be his powers. Maybe in the fanfiction, he discovers new powers or has to learn to control his existing powers in a different way. This could lead to interesting story arcs.
Here's a different plot. Mr Dark decides to create his own parallel Glade of Dreams where he is the supreme ruler. But things go wrong as the fabric of this new world starts to tear and affect the real Glade of Dreams. Rayman has to enter this dark version of the Glade to stop Mr Dark from causing more chaos. Along the way, Rayman discovers that Mr Dark is actually lonely and just wanted a place where he could belong, which adds a new layer of complexity to their relationship.
You could also develop his character by showing his vulnerability. Maybe there's a situation where his dark powers are not enough, and he has to face his weaknesses. This can make him more relatable and complex.
One way to develop Mr Hyde is through his relationships. If he forms a friendship with someone who is completely opposite to him in nature, it can cause him to change. For instance, if he befriends a very moral and law - abiding citizen, he may start to question his own actions. Another aspect is to give him a goal. Suppose he wants to find a cure for his condition. This would drive his actions and decisions. He would have to face many obstacles along the way, and how he overcomes them would shape his character. Also, showing his emotions more vividly, like his fear when he realizes the harm he has caused, can make him a more well - rounded character in the fanfiction.
The Little Dark Master was an author. His work, How to Cure Mr. Huo, was a modern and spicy novel. This novel was about the heroine who thought her husband was a perfect prince, but the doctor told her that her husband had psychological problems and needed her to enter the subconscious world to heal him. However, when the heroine entered the school world, she found that her husband was not the person she had imagined. How to Cure Mr. Huo was a fascinating novel that was highly recommended.
Max's character can be further developed by exploring her emotional side more. For example, showing how she deals with the trauma of her time at Manticore. Also, by giving her more complex relationships, like a love - hate relationship with someone from her Manticore past.
She could be developed by facing more complex moral dilemmas involving the Dark Lord. For example, choosing between saving her friends and giving in to the Dark Lord's demands in a situation where both options have dire consequences.
One common theme is the corruption of the world. The bright and vivid world of Rayman is often made dark and gloomy, with elements of decay and destruction. Another theme could be the loss of hope, where the characters are constantly faced with difficult situations and it seems there is no way out.
Show his vulnerability. In the original, he seems all - powerful and menacing, but in fanfiction, you could give him moments of weakness. Maybe he has nightmares about his past actions or there are certain things that can physically harm him in ways not shown in the original. This would make him a more rounded character. Also, explore his relationships with other characters on a more emotional level. Does he have any friends, or is he truly alone? And if he has friends, how does he interact with them? This can all add depth to his character.
The dark heroine's character can be developed through her relationships. For example, her interactions with Beetlejuice can show different sides of her. If he constantly challenges her, she might learn to be more patient or she could become more assertive in standing her ground. Another way is through her experiences in the strange world she's in. Facing the odd creatures and situations in Beetlejuice's realm can force her to adapt and grow. Also, her backstory can be explored. If she has a tragic past, it can influence how she behaves in the present and how she evolves throughout the fanfiction.
One way to develop their relationship is through communication. Thor could open up more about his fears and insecurities, especially regarding his position as a prince and a hero. Jane could do the same about her scientific work and how it sometimes isolates her. Another aspect could be them learning from each other's strengths. Thor could teach Jane self - defense and combat skills, while Jane could teach Thor about Earth's modern technology. This exchange of knowledge would deepen their connection. Also, they could be involved in a rescue mission where they have to rely solely on each other's skills and trust, which would strengthen their bond.
