Prompto Argentum

a character from a game

Prompto Argentum is a playable character of Noctis's gang in Final Fantasy XV. He's a foreign fugitive who is also a childhood friend of Noctis. He wields firearms despite their ban in Noctis's kingdom of Lucis.

Appearance and Personality
Prompto is a young man of average height and a slender build. He has blue eyes, light freckles and short, unruly blond hair. He wears two bands on his right arm, black gloves, a dark green shirt and a sleeveless black vest with a dark red flannel shirt attached underneath. He wears black pants and black boots with red soles and lined with white fur.

Prompto maintains a playful attitude towards Noctis despite being a wanted felon. In the 1st Production Premier trailer, he acknowledges Noctis's strength, but warns Noctis's body has yet to adjust to his newfound powers. 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 to them but wishes to be useful.

In Battle
Prompto uses a variety of firearms, including handguns and shotguns. As an expert marksman, he's the only playable character who can manually aim firearms, which can be used to target enemy weak points. Prompto has the same powers as Noctis to teleport. He is presumably able to manifest guns and use them as shields.

Etymology
Prompto is a Latin word, from which the word "prompt" was derived. In this case, Prompto may mean "for the ready [man]", or "for the quick [man]". Argentum, meanwhile is the Latin word for "silver". Thus, Prompto's name may have been an attempt to translate "Quicksilver" into Latin.
