I have a lot of problems with Captain Planet & The Planeteers, but I also need an article link. Most superheroes end up with an “opposite number” at some point. Some last and become popular like Venom, Black Adam, or Bizarro. But then you have the ones nobody remembers, like the Owlman that isn’t from Watchmen. The “evil twin” was a trope even Captain Planet couldn’t escape. Dinosaur Dracula chronicles the brief and surprisingly dark life and death of Captain Pollution.
