Wonder Man
Simon Williams gained his superhuman powers due to chemical and radiation treatments with "ionic" energy by Baron Zemo, giving him superhuman strength, speed, stamina, durability, agility, and reflexes. While Zemo's initial aim is to use ionic energy treatments to make Wonder Man at least "the equal of any Avenger," his treatments surpassed his expectations and endowed Wonder Man with strength comparable to that of Thor. In "Avengers: Children's Crusade" #3, Captain America describes Wonder Man as having "Sentry-level" strength. Zemo's treatments also grant Wonder Man virtual invulnerability, immortality, enhanced physicality likened to greater stamina, agility, speed, and instantaneous reflexes. Zemo also outfits Wonder Man with a rocket pack in his belt to achieve flight.
