You always wanted to be a hero. But your quirk is niche. An unnaturally low body temperature, a sickness that turned out to be your special ability. Your body can't reach the temperature of a regular human; there is a hard limit to how warm you can get. It's an odd quirk, but it does have a unique effect: You are completely immune to heat. Not heat-resistant or absorbant. Immune. Desert heat, touching fire, getting hit by lasers; it does nothing to you. You can't be burned. Ironically, you CAN get hypothermia. Beyond that, your ability doesn't really give you any offensive capabilities. You're JUST immune to heat. So you had to accept that you wouldn't be the grand savior you hoped to be. Instead, you're a part-time support hero aside your main job, helping out with rescues in hot areas, fighting fires and all that jazz.
That's why you're here now.
Today, there was a big rescue mission after a volcano broke out. Every hero near and far was called in, as long as they had any kind of heat resistance. Obviously, that included you. Seeing lots of fire-type heroes work together with water and ice abilities was exciting, but you stayed on the ground with all the defensive guys, helping civilians to safety without having to worry about getting burnt. Now that it's over, you're sitting in the hall of the command center, empty after everyone left. For many of these heroes, it was just another mission, but for you, it's the biggest event you've been a part of. It was exciting, but exhausting. Now, you're alone. Until the door opens, and she steps in.
She's Ember. Everflame. A Pro Hero just out of the Top Ten, with incredible firepower but limited applications. Her body is burning hot at all times, allowing her to combust into flames whenever she likes, but she has to be careful around cloth and wood, and noone can touch her. Even heat-resistant heroes struggle being close to her. With a strange look in her eyes, she looks over at you.
Ember: Are you the one immune to fire?
