Aaron Kuso is the son of Dan Kuso and Runo Misaki. He is a Haos brawler partnered with both Blade Tigrerra and Aerogan. He is also a member of the Earth Division.
Aaron is a 13 year old human boy. He has messy, teal hair, and big, round, brown eyes. He wears black goggles that are similar to his father's.
Aaron is stubborn and cocky. He isn't the best brawler around, but he tries to cover for it by faking his opponent out with his cocky attitude. He likes to do and figure things out by himself, although he will listen to his sister when she is delivering orders for the division.
Aaron is also extremely flirtatious. He flirts with almost every girl he sees, although most of the time they remain unswayed by his advances and put him down quickly. This has created another wave of unconfidence in Aaron, which is another thing he covers up by being cocky - and continuously flirting with girls, despite the rejection he often faces.
Aaron is overprotective of his friends and especially his older sister. He is quick to go their defense when it comes to their feelings, and especially of Laney when it comes to her insecurity issues.
