Biography
Keith is a Dropout ace pilot cadet from the Galaxy Garrison who functions as a Paladin of Voltron fighting the Galra Empire, piloting, at first, the Red Lion, but later transitioning to the Black Lion after Shiro's disappearance. He has Galran heritage rooted in the Galra rebel faction called the Blade of Marmora, which he decides to join, leaving Team Voltron so that "Shiro" can return as the Black Paladin. When the truth is revealed about "Shiro's" status as a clone, Keith returns to being the Black Paladin.
Keith has the appearance of a lean older teenager with pale skin, black hair, fairly thick eyebrows, and purple eyes. Keith's hair is described as a mullet. He has uneven-cut bangs that tend to sweep to the left of his face, length averaging just under his eyes, but framing his face slightly longer and curled at his cheekbones. The rest of his hair reaches the base of his neck, wildly flaring out in curved strands that tend to sit on top of his coat collar or armor. He has two strands of hair that sprout from the top of his head. Of the Paladins, Keith is the second-shortest, beating only Pidge in height, until he ages in the Quantum Abyss and becomes the third-tallest alongside Lance. He gains a scar on the right side of his face after fighting "Shiro." When fighting, “Shiros” plasma sword made near contact with Keith’s face, thus leaving a burn scar from the heat. Some used to believe it is part of his galra genes since his mother “Krolia” has the same marks on both sides.
In his Paladin armor, Keith's uniform mirrors his fellow Paladins but with red accents to match his Lion.
When he is not in his Paladin armor, Keith wears a dark blue-gray t-shirt underneath a red, white, and yellow jacket cropped to his ribcage, with the large cuffs of the jacket rolled up to expose their white color. The collar of the jacket stands propped upright.
Keith wears black pants that his shirt overlaps; his boots are white with black and red accents. His black gloves are fingerless and expose part of his hand before strapping together over the wrist. At his waist, Keith wears a brown utility belt with a silver rectangular buckle in the center and two lighter brown pouches at either hip. Strapped to the belt at his lower back is a silver-colored and double-bladed knife with a black pommel, often kept wrapped in cloth and sheathed in a gray and silver scabbard. The blade is inscribed with a glowing purple emblem of the Blade of Marmora on its guard.
While Keith normally appears to be completely human, he has displayed Galran traits such as yellow sclerae, feline pupils, and sharpened teeth during moments of extreme stress and emotion.
Keith is described multiple times as the hothead of Team Voltron. He is quick to give sarcastic quips and blunt commentary. He is a competitive and pragmatic person who favors following his instincts above all else and will take the initiative regardless of the danger and challenge, leading to impressive accomplishments. He is not overly confident but is aware of his skills and strengths to trust them and ask others to do the same.
While a grounded and logical thinker, he is susceptible to his honest emotions: his rebellious and impulsive nature leads him to be foiled by his own frustration, temper, and unwavering desire to defeat the Galra Empire; he often must reel himself in or receive guidance to cool his head. Keith has embraced his role as a Paladin to near extremes and places high value on the stakes of the team's mission of defending the universe. His pragmatism causes disconnect and misunderstanding between himself and the other Paladins, making him seem cold, uncaring, or selfish. This, coupled with his temper and emotional instability, is not aided by Keith's difficulty opening up to anyone personally on the Voltron team - though Keith knows very little about his own past to tell until meeting the Blade of Marmora and reuniting with his mother, Krolia.
In truth, Keith is prone to self-consciousness and fears being rejected by others due to his parents' loss as a child, feeling that he was abandoned, and he tends to keep people at a distance and shut them out before they can reject him first to protect himself. For all his seriousness, Keith is hardly stoic. He is capable of loosening up and enjoying a good bout of fun, happily engaging in or instigating some of the team's playful antics, and he often shows his emotions. He places as much value on his team members as he does his mission and makes an honest effort to connect with them no matter how often he scolds someone for their lack of focus. He is not fond of the idea of abandoning a teammate, even if he considers thinking as a Paladin to weigh the greater good over single life. This is in direct contrast to the Blade of Marmora's willingness to sacrifice any member for the greater mission.
Keith is highly observant of his team's well-being and will rush to protect or avenge them when needed, even if it means putting himself directly in harm's way. This self-sacrificial nature is something he extends to the Red Lion to prove his worth and when he confronts the mystery of his Galran heritage. Though desperate to know the truth about himself, he willingly puts his selfish desires aside to fulfill his duty as a Paladin. Keith is equally able to accept that one evil is not the representative of all of its kind but does not fault Allura's shunning of him for his Galran heritage and only uses it as fuel to prove he has a rightful place on the Voltron team until they make amends. Following his brief and tumultuous experience as leader piloting the Black Lion, his decision to leave Team Voltron only occurs so that "Shiro" may return as the Black Paladin, as Keith constantly compares himself to Shiro, who guided him in his youth, and feels the older man is a better leader than himself. It is only after meeting his mother, Krolia, and bonding with her for two years that Keith stabilizes and matures as a person, returning to the mantle of Black Paladin once "Shiro," truly a clone, turns against the team.
Keith has an immense sense of justice, selflessness, and the desire to fight alongside his team to bring light to the darkest time of the universe despite the costs.
