AzBats (Jean Paul Valley as Batman) is the focus of Knightquest : The Crusade. The crossover showed AzBats' breakdown of mental stability, falling into eventual madness.
AzBats was a much more violent Batman then Bruce Wayne, he fired Robin and nearly strangled him to death when he got in the way. AzBats violence became more and more apparent as he changed costumes, adding more wepons and more ammo. He went through three costumes, the third not only had his trademark shurikens but also a flame thrower. His mind was breaking down as "The System" tried to make sense of his role as Batman and his previous role as Azrael.
As AzBats he went up against many oponents, Catwoman, Joker and Gunhawk, wounding most and nearly killed many of them. When AzBats found Mr. Freeze deranged and ready to kill Montoya, he would have killed him had Montoya not put a gun to his head, and told him that if he had knocked Freeze out there was no need to kill him. Earlier in the crusade AzBats fought a mercenery called Mekros not thinking twice he ducked so that the mercenary would shoot, and kill a man standing in front of him. At the end of the crossover AzBats let the serial killer Abbatoir die, this resulted in another man's death, Graham Etchison, finally sending AzBats over the edge.
During this time AzBats and Jim Gordon drifted further and further apart, Jim not liking the new "look" and destroying the Batsignal on the police station roof. Harvey Bullock however, liking the change and aided AzBats.
