Hysterical Strength

Hysterical Strength also sometimes referred to as Superfire, is a technique used by some Third Generation pyrokinetics.

Usage
is a technique that gives a Third Generation 100% usage of their Ignition Ability, whereas only 30% is usually used. While Shinra uses it, his flames turn blue and claw-like.

Benimaru Shinmon somewhat confusingly remarks that unpowered individuals can also utilize Hysterical Strength, later cryptically calling Akitaru Obi's physical might an application of "Hysterical Strength". Whether he was speaking metaphorically or literally is unclear.

Trivia

 * This technique seems to be based on the real world phenomena of hysterical strength: a display of extreme strength by humans beyond what is believed to be normal, usually occurring when people are in life-and-death situations.
 * The aspect of Third Generations only using 30% of their full power under normal conditions may be a reference to a now-debunked theory that humans only use 30% of their brain at any time.
