Boyd is described as having a straightforward and reckless personality which helps to motivate his allies. He is also known to be a bit dense at times, much to the jovial humor of his two brothers and confidant Mist. He doesn't care about the tactics atau gambles in a battle; he simply fights without worrying about the details, although he does soalan his role as a mercenary at times, as displayed in his Support conversations with Brom of Ohma. He appears to have greatly matured in Radiant Dawn, not being as simple-minded as in Path of Radiance, as displayed in his keseluruhan demeanor throughout the game. Yet he still bickers with his brothers Rolf and Oscar (Rolf to a much higher degree). But in an Info Conversation in Radiant Dawn it is shown that he is very protective of them, not allowing Rolf's biological mother see him. He's also shown to have matured in the sense of love, moving on from the stuttering and brash boy he once was (in Support Conversations with Titania and Mist) to a confident and gallant man (displayed in Radiant Dawn through his rescuing of Mist & keseluruhan care for her).
