X-Men is set to make comic book history by featuring the first same-sex marriage of a superhero.
Openly gay mutant hero Northstar proposes to his longtime partner, Kyle, in the 50th edition of Astonishing X-Men.
Northstar, who came out as Marvel's first gay character in 1992, will marry in issue No. 51.
"Whenever you tell a story that touches upon an issue people are passionate about, you open yourself up to controversy and some very heated comments, both supportive and critical," Marvel's editor-in-chief Axel Alonso said.
"But as long as we continue to tell good stories, with nuanced characters from different walks of life, we feel that we're making our comics accessible to the widest possible audience."
Alonso says the writers started thinking about such a storyline after New York legalised same-sex marriage last June.
"Most of our characters reside in New York, and our stories always work best when we reconcile them against the real world, so it raised some questions," he said.
