Pokemon: Umbreon
Ability: Moonshadow
Moonshadow is an ability that allows the user to turn into shadows. In a sense, this is the only way a shadow can exist without anything to cast it. At first glance, it may seem similar to Shadowgate, but there are great differences. Shadowgate does not turn the user into shadows, it merely allows them to use shadows as gateways. Moonshadow does not allow the user to teleport around places; it only turns the user into shadows, an intangible absence of light. The only way to hurt the user while in he/she's in shadow form is to use your own shadow to fight. Umbreon uses this ability to do petty crimes (Such as replacing coffee with apple juice), so he's always being chased after by the cops.
