I’m creating a superhero story, and one of the heroes is a character named Joseph Kroger, AKA The Phoenix. He can create fire with mind, and manipulate it. He also has a high tolerance for heat and therefore cannot be severely burned. He also like black leather, motorcycling and whiskey. Fire manipulation, or pyrokinesis, is often exclusively used for offensive fighting. My question is, what possible ways could pyrokinesis be used defensively?
Wall of fire is usually pretty good. Not as good as they hoped here, but still good.
A firestorm with high winds and fire tornadoes should give attackers pause. They should pause because the wind is towards the fire, through the fire and up; a rough trip. Besides being hot and super windy, there will not be much oxygen left there.
Since Joseph has a high heat tolerance, he would be able to shield himself with a wall of fire. Not a shield in the traditional sense of blocking arrows or something, but nobody would want to get near that wall of fire. Assuming he can also control the temperature of the fire, his fire wall could be hot enough to instantly vaporize bullets, so even ranged attacks would be ineffective against him. Unfortunately, such high heat would probably cook anyone near him alive and things like furniture would combust. To remain as non-destructive as possible, he would have to create an energy spike as the bullet entered the fire shield.
A. Melting/Vaporizing objects
This is self-explanatory. He could radically raise the temperature of incoming projectiles.
He could radically increase air temperature, creating bursts of plasma that result in explosions. These could distract the attacker. Simple heated air could also distort their vision.
C. Defensive heating
He could superheat the weapons of his foes, or the magazines of firearms.
