Galahad distinctive characteristic is his white hair and black eyes. He wears a white buttoned vest. He wears light grey pants and a black belt, connected with the sheath of his sword. He wears silver and golden armour on both shoulders and knees. He wears black, elbow-length gloves and black boots.
Galahad is the most intelligent member of the guild, due to the fact that he had learnt much from books in the Real World, plus the fact that his father worked as programmer of SAO, therefore he serves as Galant's advisor and the one that shows the team a strategy, as Galant leads the Guild during the battle.
Galahad is also merciful and kind-hearted, even with NPC and monsters, he does not like to kill, but he knows that without this, he will not be back to the real world so he resigned to do so.
Galahad also feels guilty, and blames himself of trapping his own friends in the death-game.Though his friends told him many times that they did not think that, Galahad still does not forgive himself.
He attended school as every typical boy of his age. Among his classmates where his friends: Galant, Lance, Guinevere, Gawn, Dagonet, Bors, Percival, and Tristan. Thanks to the last one, they obtained the game Sword Art Online and the NerveGear, since his father was a worker in Argus. They logged in and soon discovered that they could not log out. When Kayaba Akihiko revealed his true intentions creating SAO, they created a guild called "Royal Knights".
Galahad shows very little skill in the ways of combat. If overwhelmed by an opponent, he is quick to surrender or be saved by another of his teammates. Even still, as his training as a warrior continues, his skill augments a little. Galahad's best weapons are his courage and his intelligence.
