One common theme is power comparison. Since Saitama has such overwhelming power in One Punch Man, fanfictions often explore how that power stacks up against the Huntsmen and Huntresses in RWBY. Another theme is the clash of different worlds. The modern, somewhat comical world of One Punch Man and the more fantasy - based RWBY world coming together creates interesting scenarios.
Character interaction is also a big theme. Writers like to imagine how the characters from both series would get along or not. For example, Genos and Ruby could form an interesting friendship based on their different but equally strong desires to be heroes. Also, the idea of training and growth is there. Maybe Ruby could learn some unique fighting styles from Saitama or vice versa.
A common theme is the clash of powers. Since Deku has his own set of powers from My Hero Academia and he's in the One Punch Man world, there's often exploration of how his powers compare to the likes of Saitama's. Another theme is adaptation. How does Deku adapt to this new and very different hero environment.
The theme of adventure is also prevalent. Fangirls take their characters on adventures through the various locations in the One Punch Man world. They might explore the strange and dangerous places, face off against powerful monsters, or uncover secrets about the world that weren't known before. This allows for a lot of action and excitement in the fanfiction, and it also gives the fangirl character a chance to prove herself and grow.
One common theme is power and powerlessness. In the context of slavery, characters who are slaves often lack power, while those in control have a lot. This is interesting when compared to the normal One Punch Man setup where Saitama has all the power.
One common theme is power comparison. Writers often explore how Gohan's power from Dragon Ball would stack up against Saitama's in One Punch Man.
One common theme is the clash of power levels. One Punch Man is known for its extremely powerful characters like Saitama, while Undertale has a range of characters with different abilities. Fanfictions often explore how these different power levels interact. For example, how would Saitama's one - punch ability fare against the powerful bosses in Undertale? Another theme is the exploration of different worlds. The two universes are very different, and fanfictions like to play with the idea of characters traveling between the two. It can be a really interesting concept as they bring their own cultures and values with them.
Character growth is also a big theme. For example, some fanfics might have characters from One Punch Man learning about the importance of teamwork from the Persona 5 crew, or the Persona users becoming more confident like Saitama. Additionally, the exploration of different worlds is a theme. How would the normal world of One Punch Man react to the Metaverse of Persona 5 and vice versa? There are many possibilities that fanfic writers like to play with.
One common theme is the exploration of Saitama's power in different universes. For example, when he crosses over to a universe with magic, how his physical strength compares to magical abilities.
There are several. The theme of identity is one. Shirou has to re - evaluate who he is in a world full of overpowered heroes. Cultural clash can also be a theme as he comes from a different fictional universe with its own set of values. And then there's the theme of friendship. How he forms bonds with the characters in One Punch Man, whether it's with the laid - back Saitama or the ambitious Genos.
One common theme is Sonic's training. Fans often write about Sonic trying to become stronger, maybe learning from Saitama or other powerful characters in the One Punch Man world. Another theme is Sonic's rivalry, perhaps with other speed - based characters or those who underestimate his abilities.
Identity exploration is also a theme. The sister might be struggling with being in Saitama's shadow or trying to find her own identity as a hero or just as an individual. She could be trying to make a name for herself without relying on her brother's fame.
