Characteristics
In the original Star Fox, Fox wears an orange suit with a flight jacket and grey boots, along with a communication device on his head. In Star Fox 64, he wears a green suit and his jacket sleeves are rolled up to his elbows. Also in Star Fox 64, if the game is played at a certain difficulty, Fox wears a pair of sunglasses. In Super Smash Bros. and its sequel, Melee, Fox appears as he did in Star Fox 64. In Star Fox Adventures, he has a white vest instead of a jacket, his headgear is replaced with a device on his wrist, and wears a knee pad on his left leg. He also wears a large backpack for carrying items, such as Krystal's Staff and the CloudRunner Flute. In Star Fox: Assault, his appearance changes drastically. He wears a green and red jumpsuit, a white vest, pads on his knees and shoulders, and his boots are red and black instead of gray. As in Adventures, his communication device is on his wrist. In Star Fox Command, Fox has gone back to his Star Fox 64 attire, but without his sleeves rolled up. In Super Smash Bros. Brawl, Fox has a similar appearance of his Star Fox 64 and Command designs. Although Nintendo has not officially cited Fox's height in a game manual, Nintendo Power released a card featuring Fox, which stated his height, during Star Fox 64, to be 5'8", his weight to be 155 lbs, and his age to be 18. Fox would be 26 in Adventures (as Adventures takes place just 8 years after the events of Star Fox 64), 27 in Assault (the game manual stated 1 year had passed since the conclusion of Adventures), and 29 to 30 in Command.
In the 1993 Nintendo Power Star Fox comic, Fox had a romantic relationship with Fara Phoenix. While slightly ambiguous, it is obvious that they held mutual affections for each other throughout the comics. Still, the comics are considered non-canon, since Star Fox 64 replaced the original SNES Star Fox title. In the official games canon, Fox became infatuated with Krystal when he first saw her trapped on top of Krazoa Palace in Star Fox Adventures. He is romantically involved with Krystal after the events of Star Fox Adventures, confirming that they loved each other when speaking with Lucy about his relationship with Krystal. During Command Krystal soon leaves after Fox asked her to leave because he feared for her safety. Star Fox Command has several different endings in which they either get back together or split apart completely. In one of these endings, the pair settles down and has a son named Marcus McCloud 10 years later. Marcus takes on his father's legacy by becoming the future leader of the Star Fox team.
Fox is known for being professional, cocky, and shy, expressing each trait in different circumstances. His professional side is shown when he is in serious situations especially in his Arwing, this is most notable side to Fox shown in all Star Fox games. Fox's cocky side was more notable than his professional side in Star Fox Adventures, where he acted more like a teenager than compared to an adult, showing low enthusiasm when taking on difficult situations and showing a habit of grasping the back of his neck with his hand when he was put on the spot. Fox's shy side is only expressed when he is around Krystal, who flirts with him frequently. His reactions are shown as him blushing, temperature rising, and constant stuttering. This is a clear sign of Fox's feelings towards Krystal. He also has shown signs of being a little self-centered and money-hungry. In Star Fox Adventures he was constantly grumbling about not being paid enough for what he was being asked to do and made references to only caring about any of this for the inevitable pay-off. He frequently rolled his eyes or sighed when he found out that he was being asked to do even more work or when a conversation with a character simply went on too long. Nonetheless, this was more bravado than anything else, as he ended up saving the day quite willingly.
