Merge:Marrow

Marrow (alias Sarah Rushman) is a Marvel Comics character, associated with the X-Men. She is a mutant whose bones grow out of her skin, providing her knives and clubs as well as body armor.

As a child, Marrow was taken in by the Morlocks, a band of grotesque-looking mutants who hid in tunnels beneath New York City. As a young adult, she formed the violent splinter cell Gene Nation until, under the orders of Morlock leader Callisto, she joined the X-Men to redeem herself. She made progress controlling her powers and learning a moral code, but eventually fell in with the paramilitary group Weapon X.

As a child, Marrow first appeared in Cable #15 (September 1994) and was created by writer Jeph Loeb and artist David Brewer. However Uncanny X-Men writer Scott Lobdell and artist Joe Madureira defined her powers and temperament.

She has shown herself to be a staunch team player (more-so with the X-Men than with either Gene Nation or Weapon X) who is prepared to risk her own life to protect those of her team-mates. Also, despite her apparent disdain for humanity, she has revealed that she would like nothing more than to be able to fit in with them and be happy. Whilst there have been occasions that this has happened for her (in an art gallery with Colossus and immediately following her genetic redesign by Weapon X), they have never lasted long and only served to increase her anger and bitterness towards the world when they have been taken away from her.

Origins
As a child, Sarah was one of the underground-dwelling Morlocks. During the Mutant Massacre that devastated the Morlock community, she witnessed the mauling of Angel by the Marauders. She was also personally saved by Gambit, who was not yet known by the X-Men. Years later, most of the surviving Morlocks (including Sarah) were apparently killed by Mikhail Rasputin, although they were actually brought to another dimension. There, Mikhail had established a citadel for himself on the top of a massive hill. The Social Darwinist philosophy of "survival of the fittest" was the only thing which governed the society. If someone could reach the summit of the hill they were considered "fit" and worthy of being part of Gene Nation.

The former Morlock leader Callisto cared for Marrow during this period and displayed a maternal attitude towards the young mutant, although the two are not known to be biologically related. When her powers fully manifested she was forced to "up the hill", becoming more savage and killing her opponents to survive. When she managed to reach the top, Mikhail considered her fit to join his elite fighting team Gene Nation, which eventually became a terrorist group whose mission was to punish humans for their hatred towards mutants.

Gene Nation
In that harsh dimension, time passed quickly, and when Marrow and several other members of Gene Nation (of who she had become their leader) returned to Earth, they discovered only a few years had passed during their absence. Marrow and the other members of Gene Nation began a homicidal terrorist campaign against surface-dwelling humans. After inconclusive battles with the X-Men and Generation X, Gene Nation were defeated by the X-Men. Marrow wired a time bomb to her own heart to force the X-Man Storm, who had herself led the Morlocks in the past, to either yield or kill her; Storm tore out Marrow's heart. However, due to Marrow's possession of two hearts to compensate for her random bone growth and superhuman regenerative abilities, she survived. Marrow eventually reunited with Callisto, and while they continued their terrorist activities, Callisto tried to hold back Marrow's more violent ways.

X-Men
After a battle with Cable, Marrow and Callisto returned to seclusion. When Callisto was injured by a Prime Sentinel during the events of Operation: Zero Tolerance, she directed Marrow to seek the aid of the X-Men. After teaming up with Iceman and Cecilia Reyes, Marrow went to the Xavier Institute. She joined the X-Men for a time, coming under the mentorship of Wolverine and flirting with her teammate Cannonball. During an adventure in another dimension, Gambit, unable to control his powers, accidentally injured Marrow. She was later hospitalized on the Skrull homeworld, thanks to the alien technology Marrow gained more control over her powers, giving her a "prettier" appearance. This led to major softening of her personality, to the point where she reached out to Jubilee following Wolverine's disappearance in the lead up to "The Twelve" storyline. Following the reorganization of the X-Men's roster during the six-month gap preceding the "X-Men Revolution", she disappeared from the X-Men.

Used by SHIELD
She was next seen brainwashed by SHIELD under the alias of "Sarah Rushman" (an alias that had also been used by the Black Widow) used as a sleeper agent. Her mission was to terminate rogue Life Model Decoys. She had a split personality (Mutant Marrow and human teenager Sarah) and had to be periodically injected to keep her implanted memory. With Spider-Man's help, she freed herself from SHIELD's control by faking a suicide.

Weapon X
Marrow was later recruited by the most recent incarnation of Weapon X, who again normalized her appearance and her powers. She betrayed the Weapon X organization upon discovering their anti-mutant nature. She reformed the Gene Nation terrorist cell and, as their leader, led several terrorist attacks on Weapon X until the rest of the group was slaughtered by Agent Zero. Agent Zero left her alone, not wanting her to become a martyr, but he warned her that he would come after her again after he had hunted down the remaining members of Gene Nation.



Decimation
Marrow was next seen as the leader of a band of Morlocks after M-Day. She gave an interview to Sally Floyd for her ex-mutant diaries. Marrow remains underground to protect and give hope to the few mutants that remain and those that fear going to the surface to live normal lives. Mike Marts, editor for the X-Men comic books, confirmed in a recent interview that although Sarah retains some of the physical attributes of her mutation, her actual mutant powers disappeared during Decimation.

Marrows interview also had a part with heavy subtext towards the upcoming Superhero Registration Act. Marrow tells her that, the louder Congressman Sykes calls for mutant registration, the easier it is for him to hide the truth. Americans are already labeled and registered a hundred different ways. There are social security numbers and credit cards. Such indignities afford you the privilege of police and ambulance services.

In Civil War: Frontline, Spider-Man explains that he trusts Sally Floyd because of this interview with Marrow.

Powers and abilities
Marrow is a mutant, with the ability to control the growth of her bone structure. Initially this was uncontrolled, but after enhancement by a Skrull medical facility, and later by Weapon X, she can mostly control this, despite each enhancement having partially failed over time. She utilizes this power in many ways, including the creation of knuckle guards, spears, and projectile spikes. She also possesses a healing factor, much in the same vein as Wolverine since every time a bone is ripped out a wound remains which closes itself soon after. She also possessed two hearts to compensate for her random bone growth, so when Storm ripped one out she was able to survive. It's possible that the first heart could have regrown due to the healing factor.

Her Skeletal bones seems to be also more durable than normal, she had easily survived heavy hits on several body parts. For example Flagsmasher hit her twice with his mace on the head without creating much damage and Sabertooth threw her against a wall with no result on her inner bones. She also jumped off the Brooklyn Bridge twice (something that would often result in death or broken bones) without any major damage being able to walk normally afterwards.

Like most mutants in X-Men who possess a healing factor, she is also more agile and stronger than average. Marrow has excellent tracking skills. Spoting a hidden Prime Sentinel even a super soldier like Sabra didn't noticed.

Alternative versions

 * Marrow makes a brief appearance in the second issue of the 2005 X-Men: Age of Apocalypse limited series, as the first one to refuse the help of the X-Men and attack them.
 * In the Ultimate Universe Mister Sinister killed four mutant kids as a tribute to Apocalypse. One of them was a girl with purple hair and bones growing out of her head. Even thought not named most people believe her to be the Ultimate version of Marrow. Since all kids where shot in the heart its possible that the girl had survived since the main universe version posses a healing factor and a second heart. The girl is the only victim whose age and area of residence were revealed. She was 14 and lived in Midtown Manhattan.

In other media

 * Marrow appears in two video games: she is a playable character in Marvel vs. Capcom 2, and is a boss character who leads both the Morlocks and Gene Nation in X-Men Legends.

Trivia

 * Marrow is the only Morlock who ever joined the main X-Men team as a member. Most others (e.g. Callisto, Leech) only helped them out as supporting characters.
 * Spyke, a male trainee X-Man possessing similar powers, appeared on X-Men Evolution, but he shared no similarities to Marrow other than his powers and the fact that he joined the Morlocks.
 * Marrow's skin, eye and hair color seem to change from artist to artist for unknown reasons.
 * In her most recent appearance in Generation M #4, Marrow can be seen in her second costume (including the unique bone structure and Caucasian skin tone), last used in Uncanny X-Men #370 from July 1999.
 * She is the only one of the four people (Joseph, Maggot, Cecilia Reyes and Marrow herself) who joined the X-men after operation Zero Tolerance who is official still alive. Maggot and Joesph have died and Cecilia Reyes whereabouts are unknown (assumed to be dead).
 * While Marrow doesn't appear directly in House of M mini series she makes a little cameo appearance in issue 8. One of the news shows the Avengers watch shows an old picture of her. It can be seen on page 17 behind the speaking bubble: "-- And we will get that information out to the public as soon as we can."
