The armored suit could notably adapt to all systems that tried to detect it. After that, it would adjust itself to remain undetected.
Considering, Batman hid from Superman's X-ray vision and other detection methods, the suit's remarkable nature is unquestionable.
You and whose army, Batman?
Batman has contingencies planned to combat members of the Justice League.
The Justice Buster is the answer.
It can track Flash's movements and attack with a frictionless coating, dehydrate Aquaman of all moisture using a foam coating. It has a citrine neutralizer and nerve attack system for Green Lantern and Cyborg.
The suit's Red Sun, Plasma Shield and Thermal function help Batman subdue Superman.
Like a Bat out of hell
Designed together by members of the Justice League, the Hellbat suit is clearly the most powerful suit in this list.
It was forged specifically to enhance Batman's physical abilities.
Equipped with wings, claws, energy blasts from the chest, the suit makes Batman strong enough to hurt Darkseid, who is almost the DC equivalent of Thanos.
However, the suit severely drains Batman's energy and metabolism.
