How to import characters in gta v?

Within the core game, the only characters available are those created by Rockstar for the story and side missions. There is no built‑in feature that allows a player to import or add additional characters through standard gameplay options. Any attempt to add new characters would require modifying the game files, which is not supported by Rockstar and is typically done through unofficial mods. Modders have created character packs that can be installed via third‑party tools, but these are not part of the official game and may violate the terms of service. Therefore, using the official game alone, you cannot import characters.
