Mount Justice was a mountain just outside Happy Harbor, Rhode Island. Inside was the first headquarters of the Justice League, the Secret Sanctuary. It was later re-purposed as the Team's base of operations, commonly referred to as the Cave. It was destroyed by a bomb detonated by Aqualad on March 23, 2016.
Mount Justice Destroyed Edit
Impulse inadvertedly brought a trojan horse tracking device that wirelessly bypassed security systems. This allowed Aqualad's Team to infiltrate the Cave, incapacitate Wolf, Sphere, Nightwing, and Superboy, and capture Blue Beetle, Impulse, and Beast Boy. Aqualad also planted a bomb which he placed in the Mission Room. Once at a safe distance, they blew up Mount Justice.
