Ant-Man
Avengers: Strength / Tech
The Ant-Man gear allows Scott Lang to shrink to several sizes, from just a few inches tall to microscopic. Originally, this incredible ability came from the use of so-called Pym Particles, released in the form of a gas from canisters on a belt, but over time Lang absorbed enough of the particles to will the size-change through his own mind. Though discovered and popularized by Hank Pym, Lang himself widened the scope of knowledge surrounding Pym Particles by identifying metrics that he applied to their use and in doing so, perhaps grew to be more adept with them than the original Ant-Man.
