You have managed to avoid your fate of Spontaneous Human Combustion by having compatibility with your Doppelgänger. This has awakened within you special pyrokinetic abilities. Notably, your ability to control fire is much greater than your peers, granting you both Second and Third Generation abilities. You are immune to fire and being burned, but are still capable of feeling heat.
As a Second Generation pyrokinetic, you are able to control and manipulate any flames that exist in your surroundings, whether they are natural or produced by other pyrokinetics. Your control might manifest as the ability to construct a wide barrier around yourself through which fire and heat are unable to pass, the ability to manipulate the flames and explosive formed when firing a gun to control the velocity and trajectory of bullets, or even absorbing kinetic energy and releasing it after conversion into thermal energy.
As a Third Generation pyrokinetic, you possess a unique way of forming and using flames from your body known as an Ignition Ability. This might take the form of producing jets of flames from your feet, allowing for flight or enhanced kicks, form and launch arrows of fire from your index finger as if from a bow, to generating fire within your body to massively increase your strength and durability.
Your pyrokinetic and martial arts abilities put you on par with those of Benimaru Shinmon; you can choose to have the same set of martial arts techniques as Benimaru, or an equivalent set of your choosing. You have mastered Hysterical Strength, allowing you to maximize your potential and utilize 100% of your pyrokinetic abilities. Your strength and pyrokinetic abilities are nearly peerless. Your durability allows you to take hits from the likes of Dragon who was able to split the Sea with his blasts of fire, and shatter the Moon's crust with his punches. Your speed allows you to easily react to and outpace individuals who can move at hypersonic speeds.
