History
A gravitational force meter is a pocket-size device used to measure the gravity and its chances in a surrounding area. Superhuman weapon manufacturer Moses Magnum always had one on his person whenever he was out, in case he needed to use it. When at an open-air concert outside Timbuktu, Magnum witnessed the attack of an alien Space-Lubber, which escaped through a small, self-generated black hole. While other attendees escaped, Magnum decided to stay because he believed the creature's power had potential as marketable weapons, especially for a man with his powers. Magnum identified that the creature was extraterrestrial in origin, and then used his gravitational force meter to make some readings, which he claimed were "off the charts". He then decided to stay and test more things, either with the meter or not.[1] In the end, Magnum fell through a black hole, probably with the meter on his person, and went missing.[2]
