How do i create my character in gta online?

Quick Answer
When you start a new GTA Online session, you create a character on the character‑creation screen; the game offers a customizable silent protagonist that you use to explore San Andreas.
Explanation
Grand Theft Auto Online lets players control a customizable silent protagonist. The character is created when you begin a new online game, and the avatar you design is what you use to roam the open world of San Andreas, including the city of Los Santos. The customization interface lets you choose the basic appearance of the character, and the character’s appearance remains consistent across all online play. Once the character is created, the player can engage in cooperative or competitive modes with up to thirty other players, exploring the open countryside and urban environments. The game’s open‑world design allows the character to participate in missions, races, heists, and a wide range of activities that are the core of GTA Online gameplay.
