Mjolnir Breaker is Azreal's Battle Gear designed by Keith Clay and Gus Grav. Unlike most Battle Gear it is has a base power level of 200Gs and was constructed using Azreal's and Maelstrom's DNA. Though it will still function with just Azreal, it functions at full power when Maelstrom is also on the field.
Mjolnir Breaker's design was influenced by canon Battle Gears Cross Buster and Terror Crest.
