Invisibility is a special ability which is very hard to accomplish. Shelby Marcus & Cyd Ripley were hit by a machine that can replicate time travel, teleportation & possession. They were hit because they were touching each other causing this charge that can make them time travel. This power is very special. It was created in 2015 by Barry Eisenberg & Naldo Montoya. Invisibility is when you can't be seen by the naked eye.
