Daniel Berkhart used the same weapons as the previous incarnations of Jack O'Lantern, along with chemical weapons that cause psychedelic and mind-bending hallucinations. His accomplice Maguire Beck was an expert designer of special effects devices and stage illusions, a master hypnotist, and skilled in chemistry and robotics, including a lifelike robotic black cat. Beck has used her advanced knowledge of computer imaging and virtual reality to improve upon Mysterio's techniques, allowing for Beck to pretend to be Mad Jack via proxies while safely hidden in her secret lair.
