The kid pirates have arrived, get ready to take them in. The serous demeanor is the result of Zoro's years of training as we can see clearly that he is as fond of pulling funny faces as all other crew members. Holding his bamboo swords in both of his hands, Zoro is determined to become the next Miyamoto Musashi.
Zoro's figure affords a limited amount of movement, as you can see from the pictures, his right arm can move up and down to wield the swords.
