Edison was the foremost technologist of the early 20th Century. He worked with Dr. Axel Brass and Hark to build the world's first supercomputer. It was room-sized, and capable of mapping the entirety of the multiverse as a snowflake with 196,833 dimensions. The computer would create and destroy Earths, looking for the answers to unimaginably complex problems.
By activating the computer, however, a portal into The Bleed was opened, and a group of metahumans came through, determined to save their world by destroying Edison's. Edison and most of his teammates died stopping them.
