One common theme is redemption. Lotor is often portrayed as a character who has done wrong but is seeking redemption, and Shiro can be the one who helps him on that path. For example, in some fics, Lotor's past actions are explored and Shiro sees the good in him that others don't.
There's also 'Shadows and Light'. This fanfiction delves deep into the complex nature of their relationship. It starts with them as enemies but gradually shows how they come to understand and respect each other. It's full of action and political intrigue as well. The author does an amazing job of writing their interactions in a believable way.
Love across differences is also prevalent. Given their different backgrounds and the history between their races, the idea of them falling in love despite all that is a popular theme. For example, in some fics, they have to overcome the mistrust of their respective peoples.
The theme of friendship - turned - more is quite prevalent. They start off as acquaintances or even rivals, and then through various events and shared experiences, their relationship evolves into something deeper, be it romantic or a very deep bond of friendship that blurs the lines.
One common theme is adventure. Lotor is often depicted as leading the reader on some grand adventure across the universe. Another theme is romance, of course, with a focus on the relationship between Lotor and the reader.
A lot of these fanfictions also explore the theme of self - discovery. Through their relationship, both Lotor and Keith learn more about themselves. For example, Keith might discover a more diplomatic side of himself because of Lotor, and Lotor might find a new sense of purpose that he didn't have before. This exploration of self - discovery adds depth to their relationship in the fanfiction.
Character exploration is a key element. Since Lance and Lotor are quite different characters, fanfiction often delves into how they would interact and understand each other. For example, Lance's more carefree nature compared to Lotor's more complex and often mysterious personality.
I really liked a fanfic called 'Hidden Feelings'. It shows how Lance and Shiro deal with their emotions towards each other while also facing the challenges in their galactic adventures. The interactions between them are so well - written and full of unspoken emotions.
One great Shiro x Kuroh fanfiction is 'The Unseen Bond'. It beautifully explores their relationship in a post - apocalyptic setting. The way the author portrays their mutual understanding and the slow - burn romance is really engaging.
One great Lance x Keith x Shiro fanfiction is 'The Bond Beyond Stars'. It beautifully explores their relationships and how they grow together. The characterizations are on point, and the story has a great balance of action and emotional moments.
