One common theme is redemption. Cole has a dark past in the Charmed series, and many fanfics focus on his journey to redeem himself. Another theme is love. His relationships with the Halliwell sisters, especially Phoebe, are often explored in different ways.
A common theme is family. Since Cole and his niece are related, it often explores the family dynamic within the Charmed world. It might show how family ties can be both a strength and a source of conflict.
I really like 'Cole Drake's Unseen Adventures'. This fanfic takes Cole on adventures that we didn't get to see in the original show. It explores his powers in new ways and his relationships with various magical beings. The writing style is engaging and it keeps you hooked from start to finish as you discover new aspects of Cole's character.
One main theme is redemption. Cole often has to face his past actions and seek redemption in limbo. Another theme is love, as his relationships with the Charmed Ones still play a role even in limbo.
One possible theme could be redemption. Cole's character has had a complex journey, and as a father figure, he might be seeking redemption through his relationship with his child or children. Another theme could be the power of love and family. His soul might be intertwined with his role as a father, and the fic could explore how that affects his actions and decisions.
Well, there are several themes that are quite prevalent. Mystery is one. The OC could be a mysterious figure that Cole is drawn to, and as the story unfolds, the secrets of the OC are gradually revealed. Another is the theme of sacrifice. Cole has made sacrifices in the show, and in fanfiction, the OC might also be put in a position where they have to sacrifice something for Cole or for the greater good. There's also the theme of family. The OC could be integrated into Cole's complex family situation, whether it's his relationship with the Charmed Ones or his own demonic family. This can lead to some really intense and emotional storylines.
One common theme is family. Since the Charmed series is all about the Halliwell sisters' bond as a family, many fanfics explore this further. Another theme is magic, of course. Fanfics often come up with new magical elements or expand on the existing powers of the sisters. And love is also a common theme, whether it's the sisters' love for each other or their romantic relationships.
In a 'Sister Charmed' fanfic involving Cole and Elizabeth, the author might be reimagining the characters' personalities. For example, Cole could be more heroic in his interactions with Elizabeth, or Elizabeth could have some unique powers that Cole is drawn to. This can add new layers to the existing 'Sister Charmed' lore.
Cole might be initially hesitant. He has a complicated relationship with his mother. He could be suspicious of her motives, especially if he has grown used to his new life away from her influence.
A common theme is power development. Since Cole has such unique powers, many fanfics explore how he can further enhance or control them.
One common theme is friendship. Cole and Walter's relationship is often explored in depth, showing how they support and care for each other. Another theme could be adventure, where they go on exciting journeys together.
