Defense Specialist was an advanced Haos Fighting Style on Bakugan Dimensions, which focuses on a set of powerful Defenses that's your opponent will be scared to attack into. The Defenses in this Fighting Style are all very different from each other, so if you play them concealed your opponent won't know which attack to use. This Fighting Style can wear an opponent out by defending his attacks, and whittling his Health Points down with your own attacks, but it can be tricky to master since you need to always be watching to see, which attacks your opponent has.
