any way the wind blows
Aero very much impersonates air with his personality. Completely carefree and frivolous when calm, and unpredictable and dangerous when angry. Because of this Aero is pretty unpredictable at the best of times and prone to mood swings. this means when he feel any emotion strong enough it triggers his powers. For example is if he is curious enough about something the air around that thing would vibrate. Another example if he wanted to be left alone because of some strong emotion a wave of air might launch them away with wave of air centered on him. Despite this he is usually calm and frivolous not worrying about the consequence his emotion may cause. he always controls an aura of wind around him that blows puts his clothes in a frenzy.
Aero carried no tools as his power source of abundant. His powers over air include being able to change to any creature of the skies specifically birds, being able to control the air around him as in to blow things away or create twisters, changing how air looks as in to create illusions, to turn into air and to feel vibrations in the air to get the location of something specific. the problem is his control over air is also influenced his emotions so when he feels an emotion strong enough it will manifest in the air around himself.
Back in heaven or where ever they were before Aero was almost feared. When he was born a massive blast of air almost destroyed the hospital he was in. they knew he could have great potential for both good and evil so they placed him in the monk monastery. For the first 4000 years life training in the monastery was enough but air needs motion and he grew restless. He started to sneak out and explore his realm. This is about when tornadoes started as the manifestion of his anger at what he saw. he saw more good than bad though and this put him into an almost impenetrable good mood. he was able to be almost completely care free compared to the other gods as as long as winds circulated the realm people were happy.
