Overcoming differences is a theme that frequently shows up. The characters in 'Sing' are very different from those in other fictional worlds. In a crossover with a fantasy world full of magic, they need to overcome the differences in their abilities and cultures to achieve a common goal, like putting on a great show together.
One common theme is the exploration of different musical styles. Since 'Sing' is all about music, when it crosses over with other universes, new musical styles are often introduced. For example, in a crossover with a historical - themed story, the characters might discover old - fashioned music styles.
Friendship is also a big theme. Fanfiction might show how the different animals in the movie form stronger bonds, or how they overcome difficulties in their relationships. It could be about two characters who initially didn't get along but then become great friends through a shared experience.
Since I'm not familiar with this specific 'sing ash crying fanfiction', it's hard to say exactly. But generally in fanfiction, common themes could be love, friendship, or struggle. Maybe in this one, it could be about a character named Sing or Ash going through some emotional turmoil and crying as a result.
One common theme is the overcoming of insecurities. For example, Meena is often portrayed as shy and having to overcome her self - doubt, especially when it comes to her singing in front of large audiences. Mike, on the other hand, may have to deal with his own past or his reputation among other characters. And through their relationship, they help each other grow.
Overcoming obstacles is also a prevalent theme. It could be external obstacles like the cut - throat competition in the 'Sing' world. Or it could be internal ones like Johnny's own family expectations conflicting with his dreams. The reader character might play a crucial role in helping him overcome these, and this theme of mutual support and growth is often seen in this type of fanfiction.
Another theme could be about their growth as musicians. How they inspire each other to improve their music, try new styles, or overcome stage fright. For instance, Johnny's discipline might influence Ash to be more focused on her music, and Ash's creativity could inspire Johnny to break out of his comfort zone.
One common theme is adventure. Since the Valerian universe is full of exciting and unknown elements, when crossed with other universes, it often leads to epic adventures. For example, a crossover with a space - opera like Star Trek could result in a story where Valerian and his companions explore new galaxies together with the Star Trek crew.
One common theme is the clash of different powers. For example, when the Incredibles cross with other superhero groups, there's always the exploration of how their powers compare and contrast.
Power struggle is a common theme. Starscream is often power - hungry in the original Transformers series, and in crossovers, this trait is magnified when he enters new universes with different power hierarchies. For example, in a crossover with the Lord of the Rings, he might try to claim the One Ring to gain ultimate power.
The theme of adaptation is quite prevalent. Asriel has to adapt to different cultures, technologies, and ways of life in the crossovers. For instance, if he enters a cyberpunk - themed world, he has to get used to the high - tech environment and the different social structures. Another common theme is the exploration of good and evil. When he crosses over to a world like the Lord of the Rings, he has to decide which side he's on and how to fight against the forces of evil in that world. This exploration of moral concepts is an important part of many Asriel crossover fanfictions.
A common theme is the clash of different assassin cultures. For example, when Hitman crosses with other assassin - themed franchises, their methods of killing, their code of ethics, and their loyalty to their respective organizations are often compared and contrasted.
