First Appearance: Uncanny X-Men#323 (August, 1995)

Powers/Abilities: Composed of blue ectoplasm, Sack is capable of melding himself inside a human body and taking possession of that body. Sack can wear a human body, always killing its host, until it is killed or he chooses to leave the form. His skin is pliable and transparent, allowing bullets to pass through without harm. Sack quickly regenerates from wounds.


(Uncanny X-Men#325 (fb) - BTS) - Mikhail Rasputin transported the Morlocks to an alternate dimension, called the Hill. After the first generation of Morlocks lived in peace, the young grew up disenfranchised, angry, and full of rage that their elders had abandoned Earth so easily.

(Uncanny X-Men#374 (fb)) - In the Hill dimension, time passed quickly as decades would flow by in a matter of Earth months. The children were kept in a stony citadel, where they grew.

(Uncanny X-Men#374 (fb)) - Life for the Morlock youths was one of constant combat as they struggled and fought to make it to Mikhail's citadel at the top of the Hill. When young mutants manifested their powers, they were immediately required to enter the combat. Those that reached the top of the Hill were required to continue fighting for their place there, even when they became Mikhail's personal guards.

(Uncanny X-Men#325 (fb) - BTS) - They found a way to return to Earth so that they could get revenge on the humans.

(Uncanny X-Men#322 (fb) - BTS) - Gene Nation attacked a disco, killing dozens of humans there in the name of mutants.

(Uncanny X-Men#323 (fb) - BTS) - Sack took over the body of forensic investigator Glenn Chen. The process is painful for the host, but always fatal.

(Uncanny X-Men#323) - When Charlotte Jones brought Cannonball, Storm, and Wolverine to Chen to learn more about the bodies, "Chen" told them that 33 had died from mysterious circumstances. Wolverine smelled Sack on Chen, though, and sliced him open. Sack emerged, impressed that Wolverine had smelled him, the Vessel burst into the room as well.

(Uncanny X-Men#324) - Jones tried placing Sack and Vessel under arrest, but Vessel stated that if the Morlocks couldn't keep them down, neither could the X-Men. Sack leapt at Jones, who shot him repeatedly, but the bullets passed through and he easily healed. Cannonball knocked Sack through the wall while Wolverine attacked Vessel. Storm blew Vessel into a wall while Sack tried possessing Cannonball, who attempted to resist as best he could. Before Sack could finish his possession, Cannonball took off and sent Sack flying. Storm hit Vessel with a mighty lightning blast that drained the rest of the remnant energy, sending all the souls sprawling out of him. One of them hit Sack, who disappeared. Vessel soon escaped as well.

(Uncanny X-Men#325) - On the anniversary of the Mutant Massacre, Marrow led Gene Nation in capturing an entire subway full of humans. Callisto returned from the Hill to recruit the help of the X-Men, claiming that the former attacks had only been tests by Gene Nation on the X-Men. They used advanced technology to block themselves from the X-Men's Cerebro. Callisto soon led Colossus, Storm, and Wolverine into the Tunnels, where they found a human murdered with his bicycle and a message painted in blood to the X-Men. Reverb tracked the X-Men's thought-prints, revealing the roster to Marrow and Sack, shocked at Callisto being there. Marrow, uncaring, told Reverb to tell the others telepathically. Gene Nation attacked, and Storm and Callisto found the subway humans running off as Sack, possessing one, shot Callisto before shedding his form and holding a gun to Storm's head. She hit him into the water with a powerful wind. The X-Men soon defeated Marrow.

(Storm I#3) - Back in the Hill dimension, Mikhail kept several members of Gene Nation as his personal guard. He kidnapped Storm and introduced her to Pain (Hemingway), Snow (Vessel), Loss, Glass (Sack), and Charm. He told Storm that they were being sent to Virginia to destroy X-Factor headquarters. When Storm vowed to stop them, the attacked, slashing her back with a knife as Callisto rushed in. Mikhail involuntarily began opening a gateway to Earth as someone was performing the Ceremony  of Light as Storm downed the Gene Nationals with a whirlwind. Callisto threatened to kill Mikhail as he'd killed Marilou (to fake Storm's corpse), but the Gene Nationals told Mikhail that if he did as Storm asked, they would detonate the bomb there.

(Storm I#4) - Loss reminded Storm of the bomb as they waited for her decision. At Storm's prompting, Mikhail moved the entire Hill population to New York City, shocking the Gene Nationals. They landed in the old Tunnels, where Cable waited, and Storm ensured that Mikhail got every last mutant there. As Cable struggled to figure out what was going on, Loss reminded them of the bomb, still threatening to detonate. Storm kept Cable under control, though he punched Mikhail once the transport was complete, and Storm held Callisto off with lightning.  Callisto departed, meeting up with Marrow, and Storm seemingly killed Mikhail, causing the Gene Nationals to respect her, not knowing Mikhail had only teleported away. As the X-Men (Cyclops, Gambit, Phoenix, Wolverine) arrived, Storm determined she would send the Gene Nationals to a struggling village in Africa, where they would have to work and strive to survive. She promised to keep a close eye on them.

(X-Men: The 198#2 (fb) - BTS) - When M-Day hit, most of the world's mutants lost their powers. Many of those who remained rushed to the X-Men mansion for safety, and were placed in a camp together. The mutants, including Fever Pitch, called themselves the 198. They were surrounded by Sentinels run by the O*N*E (Office of National Emergency), who were meant to protect the mutants. 

(X-Men: The 198#2) - Fever Pitch and Sack complained when Cyclops gave Magma and Outlaw a personal tour of the camp. With Erg, they tried leaving the camp for a walk, but the O*N*E agents refused to let them, telling them the ten miles within the compound were big enough. Erg knocked the guard aside, Sack covered another with his ectoplasm, and Fever Pitch tried blasting through the gate. When the Sentinels moved to stop them, Fever Pitch and Erg opened fire as other mutants surrounded them. Mr. M broke up the fight with a force field and helped calm the situation.

(X-Men: The 198#4) - Back at camp, Erg united the others in wanting to get out of the camp. When they tried to storm the gates, the X-Men and O*N*E blocked the way. The government activated Erg's tag to make him stand down and Sack found him unable to get the tag through the ectoplasm. Mr. M revealed that he could remove the tags peaceable and did so one by one, starting with Sack. He then, with Lorelei at his side, announced his intentions to lead the refugees outside the gates. They headed out into the woods, Mr. M turning the water solid and blocking the way of the X-Men.

(X-Men: The 198#5) - Mr. M announced his ability to protect the refugees, but Cyclops didn't believe him. From afar, Johnny Dee used his puppetry powers to force Fever Pitch into firing a blast, but Iceman shielded it. Fever Pitch shook the effects off while battle broke out. The Sentinels got involved, Mr. M was killed, and Johnny Dee was exposed before the refugees returned to camp. Later, Mr. M's body hatched butterflies.

(Psylocke I#1 (fb) - BTS) - Sack moved to the mutant island haven Utopia.

(Psylocke I#1) - Sack put Anole, Loa and Dust under his influence and threatened to kill them. Nezhno, Rockslide, Mercury, Surge and Pixie prepared to attack him, but before they could act Psylocke and Dazzler arrived. After dealing with Sack, Psylocke ordered the students to take him to the cellblock.

(New Mutants IV#14) - Sack was among the mutants assembled on Utopia inspired by Cyclops to fight an incoming wave of Nimrods for the future of the mutant race. As Random, Toad, Sack, Scalphunter, and Litterbug moved to join the fight, a Nimrod beheaded Sack and then attacked the others after squashing Sack's head under his foot.
