I miss when people made web browsers without appeasing advertisers. Remember when mozilla introduced the popup blocker and netscape actually incorporated that into their mainstream product? You never see stuff like that anymore because advertisers control everything on the internet now.

They are fairly diffent origins, viltrum is a conquering empire sending agents to other planets to conquer them, superman is the last son on a world that no longer exists and whos powers are stronger because of earths smaller yellow sun. Homelander was created by humans in a lab for marketing and profiting off of. On top of that it probabl also counts as parody.
There are a lot of superheros with similar powers or similar origins, but i dont know of any that are similar enough to win a lawsuit.
One that comes to mind is when DC sued over the similarity of captain marvel to superman But it was settled out of court and im not aware of any more recent ones.
