Adonis is an average and slim child with long, blonde hair and brown eyes (blue in the movie). In the anime he wears a green shirt, but in the movie he wears grey noble clothes.
He is a timid young boy who trains with his father in swordplay, though his father is excessively brutal and harsh when they spar.
Golden Age Arc
When he was young Adonis lost his mother, and he has been raised by his father Julius and caretaker Hassan ever since. When Guts infiltrates General Julius' manor to assassinate Julius at Griffith's behest, he witnesses Adonis training with his father. Adonis' father has great expectations of him; he exclaims that Adonis is to succeed him as leader of what he believes to be the mightiest force in Midland, the White Dragon Knights. Furthermore, Julius states that Adonis is to marry his cousin, Princess Charlotte, and rule all Midland. Hiding behind a chimney, Guts is reminded of his relationship with Gambino while watching Julius train his son. After his assassination of General Julius, Guts accidentally stabs the young boy through the chest when he approaches the door to the scene. Adonis grasps Guts' hand before he dies, much to the swordsman's horror. According to the caretaker Hassan, Adonis never once saw his father smile, nor ever knew the latter's love.
