Antasma (Japanese: アックーム, Akkumu) is one of the main antagonists in Mario & Luigi: Dream Team. Many years ago, he was once a normal bat living on Pi'illo Island. He was feeding on the nightmares of the Pi'illo race which eventually turned him into a living infestation of nightmare itself. Seeking domination, he stolen the Dark Stone, stone made of pure nightmares and the dark equivalent of the Dream Stone, and waged a war against the Pi'illo Kingdom. The Pi'illos, along with the Zeekeeper, fought Antasma to stop his wishes from coming true and managed to imprison him into the Dream World; however, just before his seal was complete, Antasma shattered the Dark Stone, causing the chunks to rain down all over the island. The shards of the Dark Stone turned all the Pi'illo into stone, causing the demise of the Pi'illo civilization.
