Often, a theme of coexistence or conflict is present. Since they are so different, they can either find a way to live side by side in the story world or be in constant conflict. Also, the idea of redemption might be there. If Mechagodzilla is initially a force of evil, it could seek redemption through its interactions with Mothra. And there's the theme of the balance of the world. Their actions can tip the balance towards destruction or restoration.
A Mechagodzilla x Mothra fanfic might explore their different natures. Mechagodzilla, being a man - made weapon of destruction, and Mothra, a symbol of nature and rebirth. The story could be set in a post - apocalyptic world where they have to work together to restore balance. Or perhaps it's a story of how their conflict shakes the very foundation of their world. There could be elements of human interference, like scientists trying to control Mechagodzilla while Mothra tries to protect the natural order.
One common theme is the battle between technology (Mechagodzilla) and nature (Mothra). It often explores how these two very different forces interact and conflict.
Another option is to look on social media platforms. There might be groups or pages focused on Godzilla and kaiju fanfiction. People could be sharing their works or know of others who write about Mechagodzilla and Mothra. You can search using relevant hashtags like #Mechagodzilla #Mothra #Fanfiction.
A common theme is the exploration of their relationship. Whether it's a friendship that develops into something more or a pre - existing bond that is tested.
A common theme is friendship. The human and Mothra often form a deep bond of friendship that helps them face challenges. Another theme is protection. They usually work together to protect the Earth from other threats like other kaiju.
A common theme is the power of friendship. The reader often forms a deep bond with Mothra, which helps them both in difficult situations. For example, in many fanfics, they face off against other monsters together, relying on their friendship.
Obviously, Godzilla and Mothra are the main characters. Godzilla, the powerful and often misunderstood behemoth, and Mothra, the more graceful and often seen as a protector figure.
In a Mothra x Destoroyah fanfic, a possible plot is that a group of humans discover a way to manipulate both kaiju. They try to use Mothra and Destoroyah as weapons in a war against other countries. However, Mothra and Destoroyah resist and end up joining forces against the humans who are trying to control them. This would show a different side of their relationship, not just as enemies but also as beings that can unite against a common foe.
One common theme is cooperation. Since they are both powerful creatures, in fanfics they often have to work together against greater threats like alien invaders or some super - powerful ancient monsters.
