The Dark Knight faced a powerful new threat known as Failsafe, which began as one of his most secret weapons. Failsafe was an android created by an alter of Batman in the event that he ever turned on his city. The advanced robot was a secret even to Batman, though he’s often employed his own secret weapons to get him out of a pinch.
Batman utilizes a number of important tools and gadgets like his batarangs and grapple gun. However, he also keeps a few hidden weapons that help him keep Gotham City safe. Something as simple as a colony of bats has helped him escape his enemies, and he keeps a close but secret group of allies to help him in his mission as well.
10 Candy Lollipops
Batman's created a dark and terrifying persona to utilize fear against criminals, who he felt were a cowardly and superstitious lot. However, he softened his edge a bit over the years so that he wouldn't also terrify the kids he was trying to help.
Nightwing revealed one of Batman's best weapons in his utility belt to young Jon Kent during his brief period as one of the best versions of Superboy. He pulled out a candy lollipop for Jon Kent, teasing his mentor about his potentially dangerous decision to keep the sweet treats so close to similarly shaped smoke bombs.
9 Gas And Tasers
Batman is well-known for his utility belt, which holds most of his incredible weapons and gadgets. However, his batsuit also contains other secret weapons that help Batman keep his identity secret if criminals get the advantage during a fight.
Bruce Wayne outfitted his Batsuit with a few different devices that could help conceal his identity. If anyone tried to remove his mask, knock-out gas or flames sprayed from hidden nozzles. The batsuit also featured a built-in taser that could electrocute anyone who touched Batman to keep anyone from removing his costume.
8 Matches Malone
Bruce Wayne developed a number of useful skills in the years before his life as Batman, including the ability to disguise himself and blend in with a crowd. Batman was the only witness to the death of a criminal named Matches Malone, which gave him an idea.
Batman decided to keep Matches Malone alive, and disguised himself as the deceased criminal. He has used the Matches Malone identity quite a few times over the years to go undercover and get inside information to use as Batman. Matches Malone is one of Batman’s most effective secret weapons that he continues to use to get closer than ever to his enemies.
7 Ultrasonic Bat Beacon
The Dark Knight has overcome insurmountable odds over and over again due to his ability to prepare for any possible outcome with a contingency plan. Batman always has a trick up his sleeve, but one of his first is still one of his best. In Batman: Year One, Gotham City police trapped the untested vigilante in an abandoned tenement building.
While it wasn't Batman's smartest decision he's ever made, he had a backup plan that helped him escape the trap. He used a device hidden within his boot to call an entire colony of bats from the Batcave for assistance. The bats swarmed the police and covered Batman’s escape while dramatically announcing his presence in Gotham City.
6 Kryptonite Ring
One of Batman’s closest friends in the comics is Superman. Fans know the Dark Knight and the Man of Steel collectively as the “world’s finest.” Superman developed a close trust with Batman that made them incredibly effective allies.
However, Superman also trusted Batman with a powerful weapon just in case. He gave Batman a secret Kryptonite ring to use against him if he ever went rogue. Batman has used the ring on more than one occasion against Superman, though it remains a closely guarded secret among the Batman Family.
5 Batmobile
Batman has used quite a few different vehicles over the years that have become known to both fans and criminals. He can fly across the city skies in the Batwing or race across the city streets in his ever-improving Batmobile.
Batman's main vehicle is definitely not a secret to the criminals he brings into Arkham. However,, they are still continually surprised by the sheer amount of varied firepower he carries on board. Nightwing even remarked it's one of Batman's final cards to play when he called it in to blast Amazo out to sea with onboard missiles.
4 T-Rex Replica
Bruce Wayne has collected quite a few interesting and unique trophies to display in the Batcave over the years. Some of his most eye-catching include a giant Joker playing card, an oversized Lincoln penny, and of course, his lifesize replica of a Tyrannosaurus Rex.
Anyone invading the Batcave would soon discover that the T-Rex replica is actually a fully animatronic robot connected to the Dark Knight's security systems. In one of the numerous realities in the Dark Multiverse, a version of Bruce Wayne even uploaded his consciousness into the animatronic replica to become the deadly Batmanasaurus Rex.
3 Martial Arts Skills
The Dark Knight is an intimidating presence in Gotham City who has become known for his menacing behavior. He's also developed a reputation thanks to some of his best inventions, though he relies mostly on his physical skills. However, Batman often surprises criminals with his incredible martial arts abilities.
Batman spent years training both physically and mentally to take on his mission as a costumed crimefighter. He worked with different martial arts masters across the world to become one of the DC universe's greatest fighters. Some criminals even believe they could take Batman out in a fight, but they are quickly taken down by his far superior fighting skills.
2 Covert Allies
Not all of Batman’s secret weapons are high-tech gadgets or specially-created tools. The Dark Knight’s greatest hidden assets are the people he has running things in the background. Batman has a few “guys-in-the-chair” who help him while in the field.
Batman’s most secret and trusted ally is his family butler and father figure, Alfred Pennyworth. He’s helped Batman in his mission since the start and dutifully operated the batcomputer when needed. Batman is also assisted by former Batgirl Barbara Gordon, who became the information broker Oracle. Batman could still do his job without them, but it would be much more difficult.
1 Incredible Wealth
Batman's greatest tool in his arsenal is also what facilitates all the other tools in his arsenal. the Dark Knight is one of the richest superheroes in comics. Bruce Wayne inherited his incredible financial wealth after the death of his parents, and it increased over the years due to his successful company.
Wayne used those resources to fund his career as Batman and manufacture the various inventions he needed to improve his tactics and gear. Batman's incredible wealth was a secret to most of his villains, and he was able to use it when needed to buy corporations, buildings, or other huge expenses to keep his mission running.
