|Manga||Shinra Kusakabe Joins the Force|
The Third Generation (第三世代, Daisansedai) are a group of individuals that have adapted to the Human Body Ignition Phenomenon, and instead of becoming a Flame Human, awakened the ability to generate their own flames via a body part or object. Because of their unique abilities, such as being immune to being burned, Third Generations usually become Fire Officers in the Special Fire Force.
Ignition Ability Edit
Main article: Ignition Ability
An Ignition Ability (発火能力, Hakka Nōryoku) is an ability granted to Third Generations. This ability allows the user to generate flames from certain body parts, such as their tongue, fist or leg, and the ability can be combined with specific types of objects like sword hilts or bubblegum.
Though gifted with the power of igniting flames, this ability also comes with some drawbacks. If the ability is overused, the user can use so much oxygen that they'll no longer be able to use their Ignition Abilities until they've regathered more. As well as this, with repetitive use of the ability, the body can begin to char, and the user can gain a lung disease.
