"Lightning. I—me too. I mean, at least I'll try. I'll try to watch out for you, too.
—Hope, promising to protect Lightning
Hope is close to his mother, confiding in her and relying on her for protection, but has had a distant relationship with his father ever since he reached adolescence. In Final Fantasy XIII -Episode i-, Hope says he runs from his problems, specifically things he can't change.
Hope starts off as naive, insecure, and sensitive. His speech is normally reserved but he has outbursts when his emotions get the best of him. His naivety makes him quick to blame others for his misfortunes, and he is easily affected by harsh words and rash actions, especially when they involve personal subjects. Hope has little to no battle experience and fears confrontation, and thus tries to flee from a fight when he has the chance.
Hope initially turns to Vanille for emotional support and protection, but later depends on Lightning as he comes to idolize her and tries to follow her example. Under her tutelage he matures into an efficient fighter and confident individual in control of his emotions. Hope becomes willing to throw himself into harm's way for the sake of others, show his sense of humor, and comfort his friends. Hope advises his companions and remains positive in dire situations, ultimately living up to his namesake.
In Final Fantasy XIII-2, Hope has grown into an intelligent and confident leader, admired by many, but continues to show moments of vulnerability whenever he reflects on his past.
During Lightning Returns: Final Fantasy XIII, Hope has physically regressed to his 14-year-old self from Final Fantasy XIII. His personality is still that of an adult, though his emotions have been sapped, distancing him from the woes of the world below. He has become emotionally disconnected from his memories, remembering past events as though he wasn't there. He still trusts and cares about Lightning, supporting her at all times and promising to be on her side no matter what decisions she makes.
"Hope is a normal boy from a normal family whose childhood on Cocoon can best be described as uneventful. Inexperienced in the ways of the world, and wont to turn to his mother for protection, he is completely unprepared for the turmoil into which his life is thrown when he is unexpectedly caught up in the Sanctum's brutal Purge.
