Nightshade

From Digibutterpwiki

Nightshade is a mysterious shadow being who appeared soon after POW Block discovered what the B Block actually was. He currently reigns over Hell itself, has stolen the B Block, and now has absorbed the Creator of Darkness. His motives and history are currently unknown, but it can be assumed that they are not good.

Nightshade led POW Block to Dire, Dire Docks, where the one person who knew what happened to Paul Oswald Wilson (now known as POW Block) lived. Soon after that, Nightshade began to restore POW Block's memories. The two made a pact with one another: Nightshade would continue restoring POW Block's memories, while POW Block would assist Nightshade with his plans.

Nightshade's base of operations is the Creepy Steeple.
