Aittor

The first few years of his life, Aittor lived on his original home planet. The people there treated him as a God, though in reality he is more a Demigod than anything. He remained with his father there for quite a while, not really knowing that really they were actually in hiding. Eventually, they ended up leaving, the Demigod is brought to Asgard to live there with people thinking he was just a lost child that had been found. Nobody quite knew of his real origin aside from Frigga and Heimdall, with the former encouraging him to learn the same sort of magic skill that Loki had been taught. He would take these lessons in secret, hidden away from everybody else, not knowing just how serious the risks would be were he to get discovered by somebody.
It did happen eventually, somebody found their way into the room where Aittor was sat doing some magic, and though he quickly hid himself he knew that he had been spotted. It was his grandmother's decision to move him (only 12 at the time) to Midguard, he couldn't really protest against it, but he was worried about his father as that was the only person here he properly trusted. The Godess got assistance from Heimdall to pull off a secret mission to transport the Demigod, he was taken to Midguard without anybody knowing, not even his father had been told that this was happening.

With a more human appearance, and a name to go with his disguise, Aittor was made to live alone and attempt to survive in America. Which is quite hard for somebody who knew nothing about human life and culture. He struggled with fitting in, and he struggled with finding a school that would actually accept him, and even after that he had further problems with actually hiding his powers and his differences from humans.
After several years of attempting to tough it out, the teenager finds a cat and ends up adopting it, dubbing the cat Andesine and taking it with him when he moved States to the very convenient New York. How handy. Due to his efforts to stay out of the public eye and keep a low profile, Aittor never actually found out about the Avengers' Battle in Manhatten. He never finds out about his father attacking innocent people. He never realises that his own life would be in danger because of his connections with the person who had just attacked the City. It takes about a year or so for Aittor to start paying attention to the news, a convenient time for him to find out how awful the situation was for Superheroes or just anyone who happened to have any sorts of powers. Awful. He also continued to go to school, still under the guise of a new student.

Things would take a turn for the worse for Aittor when, on his very first day upon being transferred to a new school, he lost his temper a little bit. With the way the teacher was speaking to him, how everybody was looking at him, he slammed a hand on the desk and revealed to a whole class that he had powers. Telekinesis, more specifically, as the items on the desk had been flung around the room. That had been a total accident, the poor Demigod looked terrified, and he fled the scene very quickly. It took convincing from the teachers to get him to return to school days later, where he had become colder and more closed off, not wanting people to talk to him because he was terrified of how they might react to him. Nobody managed to get him to speak up for several weeks, but a few students made several attempts to be friendly to him. That didn't really work. He didn't particularly want to make any friends anymore. He wanted to be alone, thinking that he had messed up everything.
The year was spent with it becoming harder and harder for him to hide his magic, until eventually he broke and dropped his illusion. People saw him as who he truly was, the word most definitely got around, he returned to hiding at his home to try and avoid being confronted and question.

The hiding that Aittor attempted would not work for very long. A small group of Agents appear at his door, the Demigod would have resisted if he didn't know about the Superheroes they could call, being attacked by people stronger than him didn't sound very fun. As such, the teenager gave himself up, allowing himself to be detained. Sure, their questioning attempts would be ignored, he was just miserable and he wanted to go home and he hadn't meant to do anything wrong. It was only when Loki was brought up that the Agents gained his attention, he wanted to know how they knew about his father. He wanted to know what had happened.
It was then that Aittor finally found out about what had happened to his father. He was devestated. He also didn't realise that he had confirmed his relation to the person that these humans saw as a Villain. The Agents left him there, deciding to talk to any of the Superheroes still around New York to figure out what to do with the teen who could become a problem in the future. They couldn't lock him up, that would surely make things worse, but leaving him to be free would also be an issue.
Leaving him stuck there was an accident.
Aittor was left completely forgotten when the snap happened. Nobody came to check up on him, he was left alone for several years, it was quite detrimental to his mental health. And then, when the Infinity Stones were taken and used to restore the timeline's balance, it didn't stop the Demigod from remembering things. He held a little bit of a grudge and, the first moment he could, he took advantage of the Agent and escaped. His current role fluctuates between Hero and Villain, sometimes he does good, sometimes he deliberately does what he can to harm people. Aittor still believes that this wouldn't have happened if he wasn't left detained there for years.

-----------------------

Nobody actually knows how Aittor originally looked because of his shapeshifting, he defaults to his more human appearance now.

While he normally takes the appearance of an 21-year-old male, he has used his shapeshifting power to pretend to be female or somebody else who he isn't.

At some point, he found and stole the Sceptre that was once used by Loki. Using this, Aittor boosts his magic's power, making him stronger. And letting him illusion his own outfit into armour inspired by his father's.

Aittor doesn't actually know that his father is for realsies dead yet and he might never find out. Very sad.

He secretly really loves chocolate, and those sorts of sweet things, it's a little bit of a weakness of his, oopsie.

Aittor plays the piano, he's extremely good at it. It was a hobby of his, and he used to play it while at home quite often, but nowadays he doesn't really get the chance to play his favourite instrument.

He is left handed, and he always will be, even when disguised via an illusion. That's one thing that can give him away.

His magic is green, naturally, but with the sceptre it occasionally appears blue, very odd indeed.

He is somewhat partial to raspberries as well but shhh that's a secret nobody is supposed to know.

Aittor is pansexual. Due to he himself being genderfluid, for he can physically change his gender whenever he wants, he never really had a preference over which gender he liked. He would kiss anybody.

He luckily hasn't gone toe-to-toe with any of the Avengers yet but feels like things would probably go really badly if he did encounter any of them. the only one he feels he has any sort of real chance against is Spiderman, and even then that's only if he gets lucky with a fight.

Aittor really loves cold places. Due to his parentage, and his own natural preferences, he survives better in cold weather, if it gets to hot he very noticably gets very exhausted and tired. The one downside to being part Frost Giant is the fact that he can't stop his skin from turning blue when it gets really cold, so he wears warm sweaters to try and hide the blue. Because more people finding out would make him feel very awkward.
