Spoilering it just to err on the side of caution.
For all the digital ink that’s been spilled comparing Invincible and The Boys (subject matter, gore, characters etc.) I think there’s a key difference that the most recent episode highlighted.
We see humans in a universe of supes and we see a lot more of the human side of supes, especially Robot and Dupli-kate. They are both grappling with their own humanity in separate ways, with Robot >!learning about life in a new body!<, and dupli kate elaborating on what having multiple bodies feels like. Whereas in The Boys, you don’t have much of an “am I still human?” Question from a typical supe who learned about what compound v was, though kimiko does have something of an identity crisis in s3. Even supervillains like the mauler twins get that ship of theseus question as part of their identity.
In essence, there’s a human factor in Invincible that differentiates it from The Boys.
While the Boys series have improveda lot from the awful comics. The Boys shows is still based on a comicbook run that was basically a hit piece on superheroes (so a hit piece on fictional people). So they cared less about the characters as people and more about them being morally abhorrent to be justifiably murdered by the Boys (with the Boys’ life outside the murdering being as close to unimportant as possible).
Meanwhile Invincible (both the comic and the show) isna love-letter to the superhero genre, even if it subverts a few of uts tropes. So it takes the Marvel approach of being as much about the characters’ personal life as about them being superheroes.
