The Circuit
From Hope City Stories
A mask, but not a particularly successful one. Curator Chad Benedictine was exposed to Savant radiation from one of the exhibits at the Hope City Museum of Past Innovation, and gained the ability to transform himself into an electrostatic wave and travel through telephone circuits. However, this ability only works with analogue circuits, making the power unusable outside the museum's three-line demonstration system.
Rather than fighting crime, Benedictine wrote and illustrated a comic book series, The Human Circuit, about a hero who had the same powers in 1970s Canada, and so was a lot more effective. The comics later helped him find a successor, Closed Circuit, who applied lateral thinking to find a way to make the power useful again. This occured in a short story also called The Human Circuit.
