Azrael (Deathbringer or more commonly, The Mad Dog), is a playable character and one of the supporting antagonists in the BlazBlue series, specifically in Chrono Phantasma and Central Fiction, where he appears. He returns as a playable character and as an antagonist in BlazBlue Cross Tag Battle.
A member of the organization "Sector Seven" whose creed is to improve the world through science, opposing the NOL's creed to improve the world through Ars Magus. Azrael could care less about any of that, though. He lives for one purpose only: the thrill of fighting strong opponents. Feared far and wide as "The Mad Dog" and "Deathbringer", Azrael's physical strength is nigh-impossible to gauge. He is so powerful without the use of any Ars Magus enhancements that he can fight on even ground with some of the strongest beings in the world, such as the Six Heroes. Not helping matters is his extremely violent temperament. Once he gets worked up, he becomes a rampaging beast who will attack anyone in sight, ally and enemy alike. One of his victim was one of Sector Seven’s mercenary squad captain who is now a cyborg known as Iron Tager. No one is safe when this man decides to "devour" his prey. Because of his insatiable bloodlust, Azrael has purposefully limited his own strength using a seal called "Enchant Dragunov" to give his opponents a fighting chance: by not dying too quickly.
Azrael's fighting style reflects how proud he is of his own power. He does not use weapons and prefers to let his own body do the talking, with unrefined but extremely dangerous and brutal attacks. Beneath the raging beast, however, lies a dangerously tactical mind with battle experience to spare.
