Description of effect
Fire-type moves become stronger when Pokémon is low on HP.
Physiological Response - Biological
When the Pokémon experiences great pain and weakness, the body produces a unique adrenaline that triggers a chemical reaction in the Pyro-Sac (responsible for Fire-type Pokémon's ability to breathe fire), creating substance(s) that ignite more powerfully than normal, but cannot be produced willingly since the Pyro-Sac wasn't built to withstand the excess strain, and the higher temperatures have risk of self-injury over long-term use.
Physiological Response - Physical
None known besides those related to activing Ability, see below.
Psychological Response - Mental
This ability has no known effect on a Pokémon's mental processes or abilities.
In battle Response
When the Blaze Ability of Pokémon activates, the flames on its body burn much more intensely. Additionally, when an offensive Fire-type move is used, its power greatly increases.
This ability has no known effect outside of battle.
Researchers are currently studying how exactly the Ability affects Pyro-Sac and the fire Pokémon is using, largely in hope of even more effective heat-resistant items as well as higher-quality anti-burn medicine. Another research focuses on why Pokémon most likely to be seen with this Ability are group which Trainers nickname as "Fire-type starter Pokémon".
