His legs appear to be quite powerful, as shown when he swiped Holed'em in the groin and caused both of them great pain.
Though he is limited by only going where Holed'em goes, Kamijiro possesses tremendous strength that assists Holed'em greatly in battle. However, the two's similar personalities can cause them to sometimes get annoyed with and attack each other, even though they share the same body. Kamijiro usually obeys Holed'em's commands during battle and when dealing with enemies. Kamijiro shares a body with Holed'em after the latter consumed a SMILE Devil Fruit, and so the two normally act in tandem. It is implied by Holed'em's subordinates that Kamijiro is not very intelligent, given that he does not seem to realize that he and Holed'em share the same body, and thus each other's pain.
However, his rage can sometimes make him act rashly and attack Holed'em himself. Much like Holed'em, though, he is very violent and quick to anger. Kamijiro has a mind of his own, allowing him to act independently of Holed'em.
