Abel is a light-skinned angel with wavy shoulder-length pale blonde hair, pupil-less amber-gold eyes, and a noticeable gap in his top row of teeth. His halo has a slight wavy dent and sits tilted to accommodate his hat. He wears a yellow marching band-style uniform with epaulets, golden buttons, and pink trim, and large golden wings rest on his back. Unlike his father Adam, Abel is easygoing and calm, often speaking his mind without hesitation. He can be oblivious and tactless, unintentionally making awkward comments, but his benevolent nature drives him to welcome new friends and defend what is right, as shown when he stood up to Lute during Sir Pentious' ascension hearing.
