DC Comics' hero Green Lantern proposes marriage to his boyfriend in comic book Earth 2.

The proposal comes after gay superhero Northstar married his boyfriend in Astonishing X-Men No. 51 and Archie's gay character Kevin Keller married his husband in the January issue (#16) of Life with Archie.

Social conservatives have criticized the increasing number of gay characters in comic books.

“This is ridiculous!” the Christian conservative group One Million Moms said. “Why do adult gay men need comic superheroes as role models? They don't but do want to indoctrinate impressive young minds by placing these gay characters on pedestals in a positive light.”

Alan Scott (the Green Lantern) is revealed to be gay in the debut issue of Earth 2.

In the second installment of the comic book, Alan Scott proposes marriage to his boyfriend Sam.

“I love you, Sam. I'm crazy about you. Marry me so we can …,” an emotional Alan Scott proposes as he holds a ring.

The book's final frame, however, shows the bullet train transporting the couple exploding.

SPOILER ALERT. According to ComicBook.com, Sam does not survive the explosion and a heartbroken Alan Scott is left alone.

“Of course, it is comic books, where people don't always stay dead, so who knows what the future may hold,” the site wrote.
