Prompto Argentum

Prompto is a young man of average height and a slender build, whose visage gives off the impression of a youthful punk. He has blue eyes with violet undertones, light freckles and short, unruly blond hair, which he at a point insists "does not look like a chocobo butt". He wears two bands on his right arm, black gloves, a black shirt with a white pattern, and a sleeveless black vest with a dark red flannel shirt attached underneath. He wears dark pants with a faint leopard print. He wears black boots with red soles that are lined with white fur.

Prompto maintains a playful attitude. He is described as a skirt-chasing mood maker with a chip on his shoulder from a different social status compared to his other friends, and thus feels inferior but wishes to be useful. He makes pop culture references, mimicking old song lyrics and lines from previous Final Fantasy games, and at times breaks the fourth wall by inferring their quest is like that of in an RPG. Not having been raised among nobility like Noctis, Ignis and Gladiolus, Prompto feels out of place in formal situations.

Prompto's upbeat personality makes him easy to engage in conversations with and makes him the life of Noctis's group, but he has a short attention span. When driving the Regalia in the post-credit scene of Kingsglaive: Final Fantasy XV, Prompto loses focus on the road and afterward, he is not seen driving again.
