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. But he shows he cares on the downlow. Quite the tsundere.
