Fanfiction about 'Sofa Meets Godzilla': What are some interesting plot ideas?

To develop the characters in 'Sofa Meets Godzilla' fanfiction, consider their backstories. The sofa could have been part of a family's home for generations and has seen a lot of human emotions, which makes it empathetic. Godzilla's backstory of being a product of nuclear radiation can be delved deeper into. What if there are parts of his past that he doesn't remember? And how does the sofa's presence stir up old memories or emotions? By exploring these aspects, the characters become more interesting and relatable.

One idea could be that Godzilla accidentally stumbles into Equestria. The ponies are initially terrified but then realize Godzilla is not there to harm them. They try to communicate and find a way to send him back to his own world.

Perhaps Godzilla in human form falls in love with a human. But he is constantly worried about endangering the person he loves because of his true nature. He has to battle his own kind, who see his relationship with a human as a betrayal, while also trying to keep his human love interest safe from the chaos of the kaiju world.

A fanfiction could explore the idea of Shin Godzilla having a more sentient side. Maybe it tries to communicate with humans through some form of telepathy. The story could then revolve around the humans trying to understand what Godzilla is trying to say and if they can co - exist. For example, Godzilla might be warning about an upcoming natural disaster that only it can sense due to its connection with the earth.

One idea could be that Godzilla and Kong team up against a new, even more powerful alien monster. This would force them to put aside their differences and combine their strengths. For example, Godzilla could use his atomic breath while Kong uses his agility and strength to climb on the new monster and attack its weak points.

One idea could be that Godzilla, as a human, has to hide his true identity while trying to understand human emotions. He might struggle with the concept of love and friendship, which are very different from his previous existence.

One idea could be a story where Mechagodzilla is initially built to protect the city from Godzilla, but then they discover a common enemy that forces them to team up. Maybe an alien force arrives that threatens both of them and the planet. So they have to put aside their differences and fight together.

A possible plot idea is that Godzilla is drawn to the Geo - Front in Evangelion. The reason could be the powerful energy sources there. The NERV organization is then forced to either work with Godzilla or find a way to get rid of it. They might study Godzilla's biology to see if they can use any of its abilities to enhance the Evas. Another plot could be that an Angel takes on the form of Godzilla to deceive the Eva pilots. This would make the pilots question their usual tactics when facing an 'Angel' as Godzilla has different strengths and weaknesses compared to the normal Angels. Also, a plot where Godzilla's presence causes a shift in the power dynamics between the different factions in Evangelion, like SEELE and NERV, could be really interesting.

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.

One plot idea could be that Godzilla somehow gets transported to the Star Wars universe. Maybe the Empire tries to capture and weaponize it, leading to a big showdown between the rebels and the Empire over Godzilla.
