Well, a common theme is the clash of different cultures. When they cross over with a different genre like a historical setting, there's a clash between the modern punk - rock attitude of Hollywood Undead and the more traditional values of the historical characters. Also, the theme of friendship and rivalry is quite popular. In crossovers with other bands or groups, there are often elements of friendship forming or intense rivalries developing over things like music style or popularity.
Some fanfictions might focus on the theme of redemption. Danny may have made mistakes in his past, either in the context of the band's story or in a more personal sense, and fanfiction could be about his journey to make amends and become a better person. Also, themes related to the music itself, like how Danny's lyrics are inspired by his life experiences, can be explored in fanfiction.
One common theme is the exploration of the band members' backstories. Writers often create detailed accounts of their lives before fame. Another theme is adventure. They might be on a quest or journey, like in a lot of the post - apocalyptic or alternate - universe settings. Music is also a big theme, of course, showing how their music affects different situations and people.
I'm not sure it's a widely popular concept. It's a very specific crossover idea. While both Naruto and Hollywood Undead have their own large fan bases, combining them in this way might be a niche thing that only a subset of fans who are into both would be interested in.
Well, a frequent theme is adventure. The reader might go on tours or crazy escapades with the band. Love can also be a theme, whether it's platonic or romantic love between the reader and a band member. And of course, the theme of fandom is there too. The reader is usually a big fan of the band at the start, and that's what kicks off the whole story.
One popular theme is adventure. When the Moomins cross over into other worlds, they often go on exciting adventures. For example, in crossovers with fantasy worlds like Narnia, they might join the fight against the White Witch. Another theme is friendship. Meeting new characters from different universes and forming bonds with them is a common and heartwarming aspect. Like when the Moomins befriend characters from a different anime in a crossover.
A common theme is the exploration of different relationships. In a crossover with a different game's characters, Alexios may form alliances or rivalries. For instance, if he crosses with a Final Fantasy character, they might have to work together to fight a common enemy. Also, the theme of self - discovery is popular. As he experiences new worlds, he learns more about himself and his place in different universes.
One popular theme is power - level comparisons. Fans like to see how characters from different universes stack up against the extremely powerful DBZ characters in terms of strength and abilities. For example, comparing Superman's strength to Goku's.
Redemption arcs are another popular theme. Many fanfictions explore the possibility of Azula changing her ways. Given her complex and often villainous past in the original Avatar series, seeing her struggle with her own nature and strive for a better self in a crossover setting can be very engaging for readers.
A third popular theme is the fish - out - of - water concept. When Glee characters are thrust into the world of another show, like if they cross over with a show set in a different time period or a different type of setting. They have to adapt and it creates a lot of humorous and also heartwarming situations as they figure out how to fit in while still being true to themselves.
One popular theme is the clash of cultures. For example, when Zenyatta crosses over with a universe like the Elder Scrolls. His peaceful, Omnic nature is very different from the often war - torn and diverse cultures in Tamriel. Writers explore how his presence might change the political and social dynamics.
