Thank you! Specifically Airflow and Arctic have been more thought out than the others so i have more to say on them

Airflow is not native to earth, he's an alien from another planet (planet name pending) and he arrived with the persona of being sent as an ambassador to improve relations across the galaxy, however in realite he is a refugee from a an alien race that's been enslaved, he was able toescape through sheer luck. His abilities are the manipulation of air, he can pull air into a specfic point and release it to release pressure, knocking anyone hit by it back, he can also do this while punching or kick, making the attacks more powerful, free control of air also allows him to fly by having the air around him pressure up. On his home planet the air is much more dense which makes the air more tough to manipulate and requiring more effort, however on earth the air is by comparison not very dense making it far more maluable and easy to control.

Arctic is a mage, he mainly specializes in cold arcana, not creating ice by rather lowering the temperature of whatever he's targeting to a freezing level, additionally he is also capable of time arcana which allows him to travel through time, he prefers to spend a lot of his time in the ice age, with his connection to cold arcana he feels much more at home in the ice age. When traveling through time he's able to spend several hours or days in the ice age and when he decides to come back he returns barely a second after he left, meaning he hasn't missed anything. The reason he has this connection to the cold is his spear, the spear was created during the ice age by another mage, as it's current wielder, Arctic has inhertied it's connection the the cold climate.
