Ball and Chain Trooper

The Ball and Chain Trooper first appears in A Link to the Past as the guardian of Princess Zelda's cell. At this early stage of the game it is the most difficult enemy Link has yet faced; the weapon it is named for has a long reach and does serious damage. It also recovers fairly quickly from being stunned by the boomerang. Later in the game, when ascending the Castle Tower, Link must face several more of these foes.

The ball and chain trooper also appears in the snowpeak ruins in the Twilight princess. He seems to be reptillian and to kill him you have to hit his tail. there are two ways to do this, one ues the grapple points on the ceiling to get behind him, or sidestep his attack and ues a back blow (secret skill) to get behind him.
