Homelander is said to have been an alien baby discovered in a prairie after crash-landing who aged rapidly before becoming leader of a superhero team, The Seven, as the strongest and greatest superhero in the world.
In reality, Homelander, along with every other superhero, is the product of an experiment with refined Compound V, a chemical developed by Nazi Germany used to grant superhuman powers, by the Vought-American corporation to create a team of superheroes for merchandising profit. Also like the other "heroes" (but worse), beneath his public heroic facade he is a highly depraved, corrupt, immoral, arrogant, sociopathic bully due to a combination of the chemical's side effects and his childhood in an isolated militaristic silo.
He is allegedly responsible for the sexual assault and death (from subsequent complications) of Becky Butcher, wife of Billy Butcher, the leader of a power-patrolling CIA black ops team known as "the Boys", putting him at the top of Billy's extensive superhuman hit list.
