Another theme could be the clash of different universes. Amazo is from the DC universe and Saitama is from One Punch Man. Fanfics might play around with how these two different universes' rules and powers interact when these two characters meet. Also, there could be themes related to respect and rivalry. Saitama is often very nonchalant about his power, while Amazo is a complex android with various abilities. How they view each other in the fanfic can create interesting storylines.
Saitama would win. He has shown incredible strength with just one punch. His power seems limitless, and in a fanfiction scenario, his simplicity and raw power would likely overpower Jiren's more complex abilities.
One possible plot twist could be that Jiren discovers a way to nullify Saitama's strength. Maybe he finds some sort of energy - draining technique that weakens Saitama over time. Another could be that Saitama holds back for some reason, like he wants to see the full extent of Jiren's power, and in doing so, he gets into a real struggle.
There was no conclusive evidence to prove that there was a god living in Saitama's body. In the story of One Punch Superman, Saitama was a character with superpowers. His abilities came from his strong body and combat experience. Although he had shown supernatural powers in some plots, such as being able to emit powerful light or changing the weather, these powers were all fictional and not real superpowers. Therefore, there was no conclusive evidence that a god lived in Saitama's body.
Once in Gacha Life, there was a girl named Lily. A group of mean characters would always make fun of her unique outfits. They would laugh and call her 'weirdo' whenever she entered the virtual schoolyard. One day, Lily decided she had enough. She started to focus on making real friends who liked her for who she was. She found a small group that loved her creativity in dressing up her Gacha character. Eventually, those bullies saw how happy Lily was and they stopped their mean behavior.
There was a Gacha Life love story of two characters, Rose and David. Rose was a bookworm and David was a sports enthusiast. They met at a club fair where David was trying to promote the sports club and Rose was looking for a reading club. By mistake, Rose walked into the sports club area and David kindly showed her the way to the reading club. After that, they kept running into each other. David started to borrow books from Rose and Rose would go to watch David's sports games. Their different interests brought them together and they fell in love.
A sad Gacha Life story could be about a character who loses their best friend in the game. For example, they might have planned to build a virtual world together, but then the friend quits playing. It makes the remaining character feel lonely and sad.
Once in Gacha Life, there was a character named Lily. She was always left out by the other characters in the club. They would go on adventures and have parties, but never invited her. Lily would sit alone in the corner of the virtual schoolyard, feeling so sad and unwanted. It made her virtual heart break every day.
One positive aspect of Gacha Life is its high level of creativity. Players can create a vast variety of unique characters with different looks, outfits, and personalities. Another plus is the story - making feature. It allows players to express their ideas and fantasies through creating their own little worlds and narratives. Also, it has a large and active community where players can share their creations and get inspiration from others.
Gacha Life is generally considered suitable for a wide range of ages, but it also has some potential issues. The game allows users to create characters and stories, which can be very creative and positive. However, there have been some reports of inappropriate use by some players who create disturbing or inappropriate content within the game. So, while it can be great for kids with proper supervision, it's not entirely without concerns.
