Finding your main (primary character) in Super Smash Bros. Ultimate can be a process of experimentation and discovery. Here are some tips to help you find the character that best fits your playstyle:

Experiment with different characters: Try out a variety of characters and see which ones feel most comfortable and effective for you. Each character has their own unique moves and abilities, so it's important to find one that fits your playstyle.

Pay attention to your strengths and weaknesses: Consider which aspects of the game you excel at and which ones you struggle with. For example, if you are good at spacing and zoning, you might want to consider a character with long-range attacks. On the other hand, if you prefer close-quarters combat, you might want to look for a character with strong close-range moves.

Consider your preferred playstyle: Do you like to play aggressively or defensively? Do you prefer to play a more technical or flashy style? Different characters are better suited to different playstyles, so consider what kind of player you are and look for a character that matches your preferences.

Watch and learn from other players: Watch streams or tournaments to see how top players approach the game with different characters. Pay attention to their strategies and try to incorporate what you learn into your own play.

Overall, finding your main in Super Smash Bros. Ultimate is a process of experimentation and discovery. It may take some time to find the character that best fits your playstyle, but the more you play and learn about the game, the better equipped you will be to make an informed decision.
