In "Avatar: The Last Airbender" and "The Legend of Korra", Lavabending is a specialized bending technique of Firebending.

The answer is false because lavabending is not a specialized bending technique of firebending in the Avatar universe. Lavabending is actually a specialized bending technique of earthbending. Only skilled earthbenders like Ghazan from the Red Lotus and Bolin from Team Avatar can manipulate and control lava, utilizing their connection with the earth element rather than fire. This ability involves manipulating molten rock and earth to form lava and control its movement, making it distinct from firebending techniques.
