Superman gave Batman a kryptonite ring to keep safe in case he ever needed to stop the Man of Steel.

When The Joker corrupted Superman and the rest of the Justice League with Joker Toxin, Batman had to quickly adapt.

Valley dived into the role, though his Azrael programming drove him to redesign Batman’s iconic batsuit into something entirely different.

Valley added armor that resembled his Azrael suit, along with bladed gauntlets that fired razor-sharp bat shurikens. However, the worst gadget he added to his arsenal was a bat-flamethrower connected to his gauntlets as well. The shurikens were at least potentially non-fatal. The bat-flamethrower only added violence and carnage, which went against everything Batman stood for.
