Here's why:
* "Avatar" refers to multiple things. Are you talking about the video game "Avatar: The Last Airbender" or the movie "Avatar"? Each has different ways of customizing your character.
* No "Inferno" costume. There isn't a specific costume named "Inferno" in either of these games.
If you're referring to the "Avatar: The Last Airbender" game, you can customize your character with different outfits:
* Character creation: You can choose from a selection of different outfits and accessories during character creation.
* Unlockable outfits: Some outfits can be unlocked through gameplay or special events.
If you're talking about the movie "Avatar," there's no character customization:
* Pre-defined characters: The characters in the movie "Avatar" have fixed appearances and costumes.
To get more specific help, please tell me which "Avatar" game or movie you're referring to.
