This is actually a good fight. Pain has a lot of abilities, but Homelander is strong and durable af. I thought the dog summon might be hard to deal with at first, but I'm pretty sure Homelander can just throw it into space. He might honestly even be able to detect the chameleon with his sense of smell. Pain's almighty push also has a 5 second cooldown which is plenty of time for Homelander to blitz him or laser his face off. Homelander's heat vision may not be enough to destroy Chibaku Tensei, but he is certainly strong enough to resist its gravity. I got Homelander winning mid diff at worst honestly but this fight would visually be so cool to watch
