Katarou was a skilled Martial Artist who defeated Robin one on one in the episode " The Quest". He said this was because he trained with the Master. Robin went in search of the Master and fought a bear, a giant snake, and a monkey, before reaching the Master. In Reality Katarou was following him, because he didn't train with the Master, he just wanted to get past the guards easily , by Robin wearing them out. Robin fought him again and one, using techniques he learned from the guards. Katarou joined the Brotherhood, only to be beaten by Bushido.
