A list of all known Zero Breakers thus far in the series. This is a title specifically given to those who kill an EX-Type Zero. It doesn't matter if it was solo or in group battle, if a Knight manages to kill an Ex-Type Zero, then they are awarded the title. However, there is a difference in strength between Zero Breakers for those who managed to solo kill an EX-Type Zero, those who solo kill a High Class EX-Type Zero (said to be A-Class and above) are considered as superior. Anne and Pray are the only Zero Breakers who have defeated SS-Class Ex-Type Zeros.
