- "The Avatar State is a defense mechanism, designed to empower you with the skills and knowledge of all the past Avatars. The glow is the combination of all your past lives, focusing their energy through your body. In the Avatar State, you are at your most powerful, but you are also at your most vulnerable. If you are killed in the Avatar State, the reincarnation cycle will be broken and the Avatar will cease to exist."
- ―Roku to Naruto Uzumaki
The Avatar State is the strongest and most powerful technique that the Avatar can invoke upon conflict. It allows the Avatar to channel vast cosmic energies with the knowledge of previous Avatars, granting them immense strength and the ability to masterfully bending techniques.
