Buchwald is a dark brown, thoroughbred horse with a black mane, specially bred by the Survey Corps to be fearless, fast, and patient. His personality is lively, but amicable, though he's anxious the longer he's made to sit still, and prefers to be at least running around or trotting. He was originally ridden by Jean at age fifteen in Paradis, but died during (one of) the (many) rescue expedition(s) to retrieve Eren. Jean wished for him to be returned at the crystal.

He and Elke can sometimes be found sharing their carrots or touching noses.
