Poison Ivy

Poison Ivy is a character who appears in DC Comics comic books, most often in Batman adventures. Poison Ivy debuted in Batman #181, created by Robert Kanigher and Sheldon Moldoff. She is a misanthropic botanist and scientist with a poisonous touch, improved physical ability, and supernatural influence over plant life, capabilities she employs for ecoterrorism. She is partly inspired by the title character in Nathaniel Hawthorne's short story "Rappaccini's Daughter".

The character's appearance is regarded as iconic; she is often depicted barefoot in a one-piece garment covered with leaves and vines, with minor variances in her skin tone. She employs plant toxins and mind-controlling pheromones in her criminal acts, which are normally intended to safeguard endangered species and the natural environment from human carelessness. She has appeared in a number of Batman-related media adaptations. The Swamp Thing recognizes Poison Ivy as an entity with an elemental mystical component, whom he refers to as the "May Queen". With this power, Ivy can communicate over long distances, as she manifests in a vase of roses in Zatanna's dressing room to speak with the magician. Her control over plants has improved since her death and rebirth to the point where she can produce gigantic animated plants from seedlings in seconds, hear through plants, and channel her consciousness into plant material from great distances.
