Henry Pym (Earth-1955)

"Since I was seven years old, I've let myself be a slave to other people's expectations. Leashed to a life that drags me nowhere worth going. Robotizing soullessly through my days in the most colorless, thudding unimaginative, least frivolous way possible. All because I let people convince me that I was inconsequential without a necktie on and breakers in both hands."

Doctor Henry "Hank" Pym is an American-born English scientist and entomologist who discovered the Pym Particles, an element which can decrease and increase the size of living beings and objects. Married to Janet van Dyne, Pym unwillingly took up the role of a vigilante in the form of Ant-Man duo to his wife's obsession of using their equipment for the security of civilians. Both became founding members Justice League, and Pym later became the more violent Yellowjacket after leaving the League for his guilt in unleashing Ultron.
