Sarkies is Bellamy's right hand in his pirate crew. He is known for attacking with a extremely sharped big knife, which has gained him his nickname, "Big Knife". Besides all this, Sarkies is very fast, so his knife attacks are really deadly.

Sarkies goes into a vertical spin and uses his trademark "Big Knife" to turn himself into a human buzzsaw.
