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.
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.

A lot of these fanfictions also explore the theme of self - discovery. Through their relationship, both Lotor and Keith learn more about themselves.

This exploration of self - discovery adds depth to their relationship in the fanfiction.
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.
