The relationship can start with a power dynamic. Kotal Kahn being a ruler and Erron Black being a mercenary. Kotal Kahn could hire Erron Black for a mission. This initial professional relationship can then evolve as they face challenges during the mission. Maybe they get into a dangerous situation where Erron Black saves Kotal Kahn's life, and that changes how Kotal Kahn views him.
Another way is through cultural exchange. Kotal Kahn represents the Aztec - like culture of Outworld, and Erron Black is from a different background. They can start to understand each other's cultures. For example, Kotal Kahn could introduce Erron Black to the religious ceremonies in his kingdom. Erron Black, in turn, could share his knowledge of the different regions he has traveled in Outworld with Kotal Kahn. This mutual exchange can lead to a closer relationship.
One common theme could be power dynamics. Given that Kotal Kahn is a powerful leader and Erron Black is a skilled mercenary, their relationship might explore how their different levels of power interact. For example, in some fanfictions, Erron Black might be initially in awe of Kotal Kahn's power but then find ways to be an equal in their relationship.

Another aspect could be the exploration of power dynamics. Claude is a powerful demon, and Ciel is his master in a sense. But as they interact more, the lines between master and servant could blur, leading to a more equal and complex relationship. This could involve Ciel challenging Claude's authority in some situations and Claude respecting Ciel's leadership in others.
