In fanfictions, they often come into conflict or cooperation based on these powers. Also, the theme of isolation is present. Both characters can be seen as isolated in their own ways, and when they interact, it's about breaking down those barriers of isolation. There's also the theme of acceptance, accepting each other's differences and the role they play in the world.
The 'Jack Frost and Pitch Lemon fanfic' could potentially be a very creative take on the relationship between Jack Frost and Pitch.

In many Jack Frost x Pitch Black fanfictions, a theme of opposites attract is quite prevalent.

They start off as adversaries but gradually develop feelings for each other. And of course, there are often themes related to the magical worlds they come from and how their powers interact.
Another popular theme is adventure. Writers often send them on quests or adventures together, exploring different mythical or icy landscapes.
