Mothra is a great character to include. Her grace and power can contrast with Godzilla's brute force. They could have an interesting dynamic, like in the movies where they sometimes work together.
There might be other monsters too that are important characters. They could be Godzilla's rivals or allies in the story. For example, Mothra or King Ghidorah. And there could be some key human characters such as a brave adventurer or a smart strategist who plays a crucial role in the events related to Godzilla.
King Kong would be an obvious choice. The epic battles between Godzilla and King Kong are well - known, and a fanfiction could explore different scenarios of their encounters, like what if they had to team up against a greater threat.
I'm not entirely sure who the main characters are without reading it. But it's likely to include some scientists who study the titans. Maybe there will be some military personnel involved as well, since they often play a role in dealing with the monsters in the Godzilla universe.
One idea could be a story where Godzilla teams up with other kaiju to fight a new, more powerful alien threat. This would be exciting as it shows Godzilla in a more collaborative role.
I Am the King of Monsters, Godzilla, was a novel about a man who was reborn as the king of monsters, Godzilla. This person was reborn as Godzilla in the parallel universe and successfully bound to a system, becoming stronger through devouring and upgrading. He had subdued all kinds of giant beasts and fought against the sleeping Titans from the immemorial era. In the end, he came to China and trained with another system bound person. The novel also contained some descriptions of the chapters, but the specific plot and story development needed to be read in full.
One idea could be Godzilla teaming up with other kaiju from different universes to fight a common, powerful enemy. Maybe an alien force that is threatening all kaiju-kind.
Well, for a 'duel monsters crossover fanfiction', characters like Bakura Ryou could be included. His dual personality, with the evil Bakura lurking inside, can add a layer of mystery and danger. Mai Valentine is also a good option. Her strong - willed and competitive nature can create interesting dynamics in crossovers. Additionally, Mokuba Kaiba, with his youthful energy and his loyalty to his brother Seto, can be a fun character to involve, especially in crossovers where family relationships play a role.
Definitely include Randall from Monsters University. His sneaky and devious nature can add a lot of conflict in a crossover. If it's a crossover with a magical world, he could try to steal some magic for his own gain. Another good character is Celia Mae. Her relationship with Mike can bring some romantic subplots or comedic moments. For example, if they cross over into a high - school - type setting from another movie, Celia Mae could be the popular girl while Mike tries to win her over in a new and different way.
One popular character to include could be Dr. Serizawa. He has a long - standing connection to Godzilla in the franchise. His scientific knowledge and his moral dilemmas can add depth to a fanfiction story.
Well, it depends on your interests. If you're a huge Godzilla fan, then it's a great read. It expands on the lore, shows different perspectives of the monster battles and the world around Godzilla. However, if you're not into monster - themed stories, you might not find it as appealing.
