He wears a red jacket with short sleeves and fingerless gloves. He wears black combat boots and red goggles with tinted lenses. He has black spiky hair and blueish gray eyes.
Aen can transform into 10 aliens via the Omnitrix
Aen is quick and cocky. He often doesn't think of a plan before engaging the enemy. He has been shown to act a little serious occasionally.
