One of the main themes is identity. When Alex Mercer is in a crossover situation, especially in a godlike form, his identity can be challenged or enhanced. There's also the theme of morality. His actions in a new, different setting might be questioned in terms of right and wrong. And of course, the theme of discovery as he explores the new world he's in. For example, if he crosses over into a fantasy world, he has to discover how magic works and how it affects him. These themes often interact with each other to create complex and interesting stories.

Another theme could be growth. The child reader might grow and develop under the influence of Alex Mercer. This could be in terms of their personality, abilities, or just their general outlook on life. It's interesting to see how the two characters interact and how the child's journey unfolds in the story. There could also be themes of discovery, as the child discovers more about Alex Mercer's world and powers, and Alex Mercer might also discover new things about himself through his interactions with the child. This can add a layer of depth to the story.

Conflict is a major theme. When Issei crosses over into another universe, there are bound to be conflicts, whether it's against villains from that universe or differences in ideology with the characters there. For instance, in a crossover with 'Attack on Titan', Issei might have to deal with the Titans and also the complex political and moral issues within the Walls. And of course, there's always the theme of survival as he faces new and dangerous situations in the crossover.
