Look, I get that Homelander is a force to be reckoned with within his own series, but in the larger context of all superhero universes, no, he has nothing on the strongest entities elsewhere, Omni-Man included. The “what if Homelander fought X?” format has been a meme for a while now, and I’ve seen (probably AI-based) art showing Homelander killing the Justice League which…also would not happen.
