Though he originally created it to help the deaf, because of its temporary side effects multiple people have taken advantage of it, including Langstrom himself, often in the name of vigilantism. However, because the user becomes almost feral with its use, Langstrom has acted as both an ally and an enemy to Batman. Prime Earth/Earth 0
