Batman's latest gadget, crafted from Killer Moth's formula, is an impregnable shield that can withstand the most powerful villains' attacks. It possesses an unparalleled ability to trap and immobilize enemies in a thick, viscous foam, making it a formidable weapon against lesser adversaries but proving ineffective against Zur-En-Arrh, a formidable foe capable of disarming and overpowering Batman with ease.
Thanks to an unexpected member of Batman's rogues' gallery, the Dark Knight has developed a new gadget that could mean the difference between life and death in his latest fight.
Knowing that he can't outrun Zur-En-Arrh's improved body, Batman maneuvers the car so that the android is forced to break in through the back window. However, Bruce leaves several high-pressure foam bombs in the car as he escapes. Bruce notes that the fire suppressants are harder than steel and is based on a formula created by Killer Moth. While it's not enough to stop Zur-En-Arrh, it's enough to momentarily incapacitate him, forcing Batman to intervene.
The last several months have pushed Batman to the brink of his physical and emotional limits. As he navigated the multiverse and faced a multitude of stressors, Batman's psyche began to shift, mirroring the erratic nature of his alternate persona from Zur-En-Arrh. The backup persona's manipulations pushed Bruce to sever his ties with the Bat-Family, leading to an unprecedented solo quest that would determine the fate of the Joker. However, this confrontation exposed Batman to Zur-En-Arrh's insidious influence, briefly taking control of his body before the persona transferred its consciousness to the formidable Failsafe body.
Batman's latest creation draws heavily from a villain like Killer Moth. While Drury Walker may not be one of Batman's most prominent rogues, his extensive criminal career has yielded numerous innovative gadgets. Killer Moth is considered an anti-Batman, and his fire suppressant is an effective countermeasure against Batman's various weapons. However, this weapon's effectiveness is questionable against an opponent like Failsafe whose body is not suitable for such a weapon to be effective.Thanks to Batman's chaotic enemies, fires are an all-too-common sight in Gotham (especially because of foes like Firefly). But something as powerful as this new fire suppressant could go a long way when combating villains that love using flames to cause damage. Not only is it effective at dampening any fires, but it can trap enemies in foam that hardens to become stronger than Steel. Granted, it's not as useful when used on something as powerful as Zur-En-Arrh. But for less powerful enemies, it could really aid Batman in combating their fiery foes.
