Final Fantasy XV - Gladiolus Amicitia

Gladiolus Amicitia is a companion of Prince Noctis and a party member in Final Fantasy XV. Although not directly controllable, he is in Noctis's party and the player can co-opt moves with him and issue him commands.

He is a childhood friend of Noctis and Ignis, the eldest son of Clarus Amicitia and older brother to Iris Amicitia. As a member of the Crownsguard, Gladiolus acts as the shield of Noctis, like his father has been to King Regis. He has known Noctis since childhood and considers him a brother.

Gladiolus is the main playable character in his own DLC episode, and in an added segment to Chapter 13.
