World of Light current completion percentage

What I did was set up a 20 minute match and just play it and when its done you should get a new challenger. After you beat it, go to the home menu, close smash, then reopen it. This resets the 10 minute timer to a new challenger. Set up a match with one stock then immediately jump off the stage. You will then get a new challenger. After beating it, close the game, reopen and repeat.

Your online Smash Tag name is based on your user profile's nickname in the Switch’s system settings.

To change your nickname, go to the home menu and open System Settings. Scroll down to "Users" and select your profile. Select the "Nickname" option to pick a new name.

Note: If you change nicknames while Smash Bros is open, your new name will be applied after closing and relaunching the game.
