I'm not entirely sure specifically what 'avenging 10 fanfic' is about without more context. It could potentially be a fan - made story related to the Avengers (since 'avenging' might refer to them) but the '10' part is a bit unclear. It might be a volume number, or part of a series.
Avenging remnant fanfiction might be a story where the 'remnant' refers to a small remaining part of a group or society. In fanfiction, it could be that these remnants are out to avenge the destruction or wrongdoings that led to their being remnants. For example, if it's related to a superhero franchise, it could be about the last few superheroes avenging the defeat of their team by a powerful villain.
Love is also a fairly common theme. It could be love for the angel that drives the characters to seek vengeance. There might also be themes of sacrifice. The characters may have to sacrifice a lot in their quest to avenge the angel. For example, they might sacrifice their own safety or relationships. In addition, the theme of power often comes up. Whether it's the power the angel had, or the power the avengers need to gain to succeed in their mission.
In 'avenging ranma fanfic', Ranma is the key protagonist. He is the one who is on the path of avenging something or someone. Akane is bound to be an important character as well. Their relationship is always a crucial part of the Ranma 1/2 universe, and here it could be intertwined with the avenging plot. Additionally, characters like Shampoo and Ukyo might also be main characters. Shampoo, with her own strong martial arts skills and her complex relationship with Ranma, could be involved in the avenging in some way. Ukyo, too, has her own connection to Ranma and could bring her own brand of help or hindrance to his avenging mission.

The 'Avenging Angel' in GTA Liberty City Stories could be a fan - made concept. GTA games often have a lot of room for interpretation and creativity. Since Liberty City Stories has a complex world filled with crime, corruption, and power struggles, players might have come up with the idea of an 'Avenging Angel' - someone who tries to bring justice or their own version of it. It could be a character that players envision as having special abilities or a moral code within the chaotic world of the game.
Some great avenging spider fanfiction stories involve crossovers. For instance, a story might bring in characters from other Marvel universes. Maybe Spider - Man meets a character from the X - Men while on an Avengers - related adventure. In some fanfictions, Spider - Man has to adapt to new technology provided by Tony Stark during an Avengers operation. This could lead to really cool action scenes and new ways for him to use his powers. Also, there could be a fanfiction where Spider - Man has to mentor a new young hero while being part of the Avengers.
Revenge is the obvious one. The characters usually have a strong motivation to right a wrong that was done to them. It could be something like a betrayal or the loss of a loved one.
