Homelander vs Solder Boy 1v1, Homelander was winning and would win. It took Suped Butcher to help in holding Homelander down. Plus suped Huey. And Homelander was still able to break free and get away. 3v1 Isn't exactly a fair fight.
It's Soldier Boy, he's not soldering. Homelander was never winning. Soldier Boy made Suped Butcher look like a peasant, literally kicks his ass like it's nothing. Homelander went toe-to-toe with Suped Butcher and it was a stalemate, arguably a win for Suped Butcher. If not for Homelander's ability to flee combat on a dime, he would be absolutely embarrassed by Soldier Boy who has a far superior strength scale, a far superior 1-hitter quitter ability and isn't reliant on Mom's Milk to sooth him. The real difference between a battle tested SOLDIER vs a lab created man child with some cool abilities.
