The Wasp (Janet van Dyne) is a fictional character, a superheroine in the Marvel Comics universe and founding member of The Avengers. Created by Stan Lee and Jack Kirby, the character first appeared in Tales to Astonish #44 (June 1963).
After the character's 2008 death, Henry Pym became Marvel Comics' new Wasp briefly.
Both versions are depicted as having the ability to shrink to a height of perhaps several centimeters, grow to giant size, fly by means of insectoid wings (which appear only at small size), and fire energy blasts.
In May 2011, the Wasp placed 99th on IGN's Top 100 Comic Book Heroes of All Time.
