Name: Mikael Raikova
Gender: Male
Age: 24
Class: Pro-Hero ((Was Class A))
Sexuality: Straight

Looks: Mikael's skin in very, very tan, a result of his habits of taking naps in the sun to absorb some heat. He has bronze/red hair that doesn't quite reach his shoulders, but is close. His eye color changes based on how much heat he has stored and how much he is outputting, going from a dark grey at dangerously low levels, through red, orange and yellow up to white at dangerously high levels.
Compared to other heroes, Mikael isn't tall or muscular. But compared to an average citizen, he still isn't particularly tall, but he has the muscular structure of the average football player.

Personality: Mikael has modeled his heroic persona after All-Might, like many others. On patrol, he's been called; "Cheery", "Bright", and, a personal favorite of his, "The embodiment of f%#king sunshine". Though he doesn't interact much with citizens with his normally nocturnal schedule.
When off patrol, he is usually just a toned down version of his heroic persona, with a bit of playful sarcasm added. But if his sunbathing/daytime-naps are interrupted, he is irritable, but quiet and reserved in order to avoid starting conflicts.

Backstory: As his name might suggest, he was born in Russia, but his family moved to Japan while he was in middle school. A fact he's infinitely happy with, as once his quirk didn't have to focus on keeping his temperature high enough to stay alive in the cold temperatures, it fully developed to the quirk he now enjoys. With a fully developed quirk, he got into and eventually graduated from UA. While in his third year, he had been Sidekicking for Endevor, but they parted on bad terms, with Mikael quitting just before Endevor could fire him (literally or otherwise).

Hero Name: Temperature Hero: Kelvin.

Quirk: "Heat Sink"
This quirk has three main parts; Absorption, Release and Control.
Absorption: Mikael is able to passively absorb and stock up heat from sunlight or ambient heat in the air. He could also actively take in heat, effectively cooling things to the point of freezing, he can do this to air around him or anything that he can touch with all five fingers of one hand. One side effect of this is that his body is unable to regulate its own internal temperature, so he is technically classified as cold-blooded. This means his temperature can drop dangerously low when he either spends too much heat, or doesn't absorb enough, or dangerously high if he overuses his quirk, though his temperature doesn't increase as much as it should with how much he he can store.
Release: Mikael can release the heat from anywhere on his body, though he can 'throw' heat in a direction. If the temperature he lets off is high enough, he also lets off some light, which has been found to be identical to sunlight. If he pushes his limits so he starts to burn himself, he can super heat air to the point of turning it into Plasma, though this quickly drains his store of energy.
Control: When he forms Plasma, he is able to shape it and launch it so it keeps its shape until it cools off enough to dissipate. During that time he can adjust its flight path slightly.

Costume: His costume is pretty simple, made up of a pair of fingerless gloves, a sleeveless vest, a pair of pants and boots. The fabric is heat resistant, though he does still burn through it when he makes plasma. It is also heat activated, so it changes color with heat, at his resting temperature it is a dark purple, though as he heats up it goes up through red and orange, then finally a bright yellow. The only constant is the large, white 4-pointed star on his chest and the matching stars on the backs of his gloves.

Special Moves:
"Starfall." Mikael creates and throws a collection of small balls of plasma that explode on contact.

"Thermals." By heating air so it rapidly expands, he can launch himself forward, as well as add force behind his blows. Using this, he can't quite fly, but can launch into the air, then glide until he gets close enough to the ground to launch himself again.
