Fictional groups are collections of characters or entities created in literature, film, or other media that share a common purpose, identity, or theme. These groups can range from heroic teams, like the Avengers, to villainous organizations, such as SPECTRE. They often serve to drive the plot and develop character relationships. These groups can also reflect real-world social dynamics, exploring themes of friendship, loyalty, and conflict. Examples include the Fellowship of the Ring from The Lord of the Rings and the X-Men from the Marvel universe. Such groups help audiences connect with the story and its characters on a deeper level.
