Described as "the deadliest of blossoms," Deadly Nightshade possessed an unexplained and formidable control over the world of plants. She was having a potentially catastrophic affair with Imp. Her real name was never revealed.
Deadly Nightshade had complete control over plants and anything related to the plant world, being able to instantly grow and animate them at will. She used these powers as her primary means of assassination. She once killed a man by filling his throat with pollen, slowly choking him to death. Her vines were shown to have consumed entire city blocks.
