Dr. Henry "Hank" Pym, Ph.D., was an American entomologist, biochemist, roboticist, engineer and physicist, and "Scientific Adventurer". He was considered one of the smartest humans on Earth. He discovered the Pym Particles, subatomic particles which can increase or decrease the size and mass of objects or living beings. He built a suit and for a time, became the original Ant-Man, fighting beside his future wife, Janet Van Dyne, who had taken on the mantle of the Wasp. Alongside Van Dyne, he became a founding member of the Avengers, "Earth's Mightiest Heroes". Pym was the creator of the deadly android, Ultron. He was also able to modify his Pym Particles to allow him to grow in size to become Giant-Man, and later Goliath. After a nervous breakdown, he changed his identity to Yellowjacket, and then later to the Wasp to honor his deceased ex-wife. His skills in science also led him to be appointed Earth's Scientist Supreme.
