Marvel's Other Immigrants Super Post!

Every so often, a random change made in an adaptation will find its way into the original comics.  They're not whole new characters, they're not a certain look, they're just...stuff.  These are their stories.

Morph's name

A character named Changeling (Kevin Sidney) first appeared in Uncanny X-Men #35 (August 1967) as a member of the villainous Factor Three; he later secretly joined the X-Men but died the same issue.  In the first episode of the X-Men animated series (1992), the creators wanted to show the seriousness of the series, so they made the character an X-Men member so they could kill him off; however, in the show, he was named "Morph".  This would be the name he used when he appeared in the alternate reality "Age of Apocalypse" in X-Men Alpha (January 1995).

Spider-Man's organic web spinners

Until the Spider-Man movie (2002), Spider-Man's webs had always come from a device he invented.  The creators of the movie thought it wouldn't make sense for a high school student to invent such a complex device, so they gave him organic web-spinners.  The storyline Spider-Man: The Other (2005) gave him organic webshooters as well (among other new powers), but they have all disappeared after the Brand New Day storyline.

Rogue's real name 

One of Rogue's defining traits was that she had no recollection of who she was.  In the X-Men movie (2000), though, her name was Marie. After X-Treme X-Men #43 (April 2004) claimed her name was "Anna Raven" (alluding to actress Anna Paquin and using Mystique's first name as her last), the Rogue ongoing series followed in the footsteps of both in September 2004 by revealing her name is "Anna Marie", last name still unknown.

Mutant Response Division

The Mutant Response Division is a UN-affiliated office whose purpose is to deal with international mutant threats.  They first appeared in the first episode of Wolverine and the X-Men (September 2008) and later made the jump to comics in X-Factor #204 (June 2010).  They have since also been mentioned in The Avengers: Earth's Mightiest Heroes (episode: "The Man in the Ant Hill", September 2010).
