Ant-Man’s character background

Hank Pym discovered a micro-shaped atom that can shrink the body to the size of an ant and then return to the size of a normal human. He named the atom Pym particle after himself (Pym particles). After becoming smaller, Pym's strength increased. Afterwards, he studied ants vigorously and made an electronic helmet that could communicate with ants, becoming Ant-Man who could shrink and control ants freely.

After the scientist Dr. Dine was killed by an alien villain, his daughter Janet approached Hank, hoping to use Pym particles to avenge her father. Hank told Janet his identity as a hero and gave her Pym particles to become the Wasp. Afterwards, the two worked together to arrest the alien villain, and the two became heroic partners and lovers. Later, Hank proposed the concept of forming a team of heroes, and Janet came up with the name of the team, Avengers. Later, Ant-Man and the Wasp joined Iron Man, Thor and the Hulk to resist the threat of the evil god Loki. At the suggestion of the Wasp, the five formed the Avengers, the most powerful group of heroes on earth.

After joining the team, he found that his strength was not as strong as Thor and Captain America, so Hank decided to study using Pym particles to enlarge his body and become a Giant-Man. However, due to the use of Pym's improper particle caused him to be locked for a long time at a size between a giant giant and an ordinary size - 10 feet tall (approximately 3.05 meters). He finally recovered, during which he used Goliath ( Goliath).
