Cain, who portrayed the superhero in the '90s TV series "Lois & Clark: The New Adventures of Superman," accused the comic book publisher of "bandwagoning" over the news.
"They said it’s a bold new direction. I say they’re bandwagoning," Cain said while appearing on "Fox & Friends" Tuesday.
He added, "I don’t think it’s bold or brave or some crazy new direction. If they had done this 20 years ago, perhaps that would be bold or brave. But brave would be having him fight for the rights of gay people in Iran where they’ll throw you off a building for the offense of being gay."
Cain argued that focusing on other issues would have been more noteworthy.
"Why don’t they have him fight the injustices that created the refugees whose deportation he’s protesting? That would be brave, I'd read that. Or fighting for the rights of women to attend school and work and live and boys not to be raped by men under the new warm and fuzzy Taliban."
He added, "There’s real evil in this world today, real corruption and government overreach… It’d be great to tackle those issues. I’d like to see the character doing that."
DC Comics hailed their new direction for Superman in a Monday statement, in which DC Chief Creative Officer and Publisher Jim Lee said they "couldn’t be prouder to tell this important story."
Tom Taylor, the writer of the newest Superman take, said, "Everyone needs heroes and everyone deserves to see themselves in their heroes."
He added, "Superman's symbol has always stood for hope, for truth and for justice. Today, that symbol represents something more. Today, more people can see themselves in the most powerful superhero in comics."
The romantic relationship between Superman and a male friend will debut in the Nov. 7 issue of "Superman: Son of Kal-El."
