Transformation is also a key theme. Dark Mikey has obviously transformed into a darker version of himself, and Karai may also experience some sort of change in relation to him. This can be physical, like in a fight where they both gain new skills or powers, or it can be emotional, such as growing to trust or distrust each other more. Additionally, the theme of mystery often comes into play. Karai has always been a bit of an enigma, and Dark Mikey's new state adds another layer of mystery to their relationship.

It's all about exploring the uncharted territories of their personalities and the possible dynamics between them.

Another theme might be the idea of forbidden love, as they are on opposing sides in the show. Also, the exploration of their complex feelings for each other, which a kiss would represent a significant moment in.
Another theme might be adventure. Given their nature as turtles who often go on adventures, the fanfiction might incorporate their adventures in a way that also showcases their relationship. For example, they could be on a mission together and their bond is tested or strengthened during that time. It could also involve themes of self - discovery, as they learn more about themselves and each other through their interactions.
One common theme could be reconciliation. Maybe they've had a huge fight and the kiss is a way to make up. Another could be a moment of shared joy or celebration. It might also be used as a way to show a new level of understanding between them.
One theme could be redemption. As mentioned before, Karai has been involved in the Foot Clan's wrongdoings. April could be the catalyst for her redemption, showing her that there is a better way. Another theme could be friendship against all odds. Their different backgrounds and loyalties make it seem impossible for them to be friends, but the fanfiction could explore how they overcome these barriers.
