A large man by nature, Kave's early life resulted in particularly tanned and sun wrinkled skin, the latter partially due to genetics. While the tan has been lost from spending most of his time on space ships, the wrinkles have remained to give him an appearance almost in his early fifties, despite his three decades. His eyes are grey, though this is largely dependent on personal opinion, as some consider the colour to be a peculiar blue. While he used to have a series of tattoos on his left cheek, he has had these carefully removed, and it would take a close eye and practice to determine that something had even been there in the first place. His dyed red hair is rather messy, short (approximately 7 centimeters), and somewhat thin.

Kave favours loose fitting dark brown clothing, often robes, which serves to disguise his thickly built figure. This is accompanied by soft, short brown boots, and (whenever possible) gloves. While Kave still appears as a large man, the majority of his wardrobe makes it difficult to ascertain just how much of this is due to musculature.

Kave is built for endurance; rather than a lean build emphasizing efficient energy usage or a large build emphasizing pure power, his training has given him an endomorphic build.
