Shari Wayward is one of the remaining Survivors of the Mayor's attack on Econia.
She survived the attack by hiding in an underground cave, which later became her home for a few years. In that amount of time, she hid in the shadows out of The Mayor's sight.
One night, a mysterious liquid from one of the Mayor's Factories spilled out into the cave, flooding it entirely. Shari should've drowned, but the liquid gave her extraordinary abilites. She could turn into a ghost, and can stay underwater for a long time. However, she lost all memory of he childhood, including the existance of Josh.
