X-Men: Emperor Vulcan#1 (fb) - BTS) - A secret cabal within the Shi'ar Empire organized the Shi'ar Death Commandos, a unit composed of warriors from various extraterrestrial races, and sent them to Earth to slay Marvel Girl (Rachel Grey, who once wielded part of the Phoenix Force) and all related to her.
(Uncanny X-Men#468 (fb) - BTS) - The leader, Blackcloak, was tasked to brand Marvel Girl according to canon law, and brand her according to civil law. The brand would allow the Shi'ar to always track her.
(Uncanny X-Men#466 - BTS) - On Earth, the Commandos surrounded the home of John and Elaine Grey.
(Uncanny X-Men#467 - BTS) - Unable to decipher who Rachel was among all those inside, the Commandos initiated their secondary objective, that of slaying all those who were biologically related to Rachel. Over the next 24 seconds, multiple targets were killed, including Gailyn and Joseph Bailey, Derry Campbell, Phyllis and Roy Dennefer, Brian and Julia Grey, John Grey, Fred Harriman, Julian, Kindra, Liam, Terry Maguire, Mary-Margaret, Roger, and Bekka Wallis, leaving only Rachel and Elaine Grey alive. The X-Men (Nightcrawler, Psylocke, and Shadowcat) attacked. Blackcloak marked Marvel Girl with a phoenix tattoo so that she would always be trackable from then on.
(Uncanny X-Men#468) - The battle continued and more X-Men (Bishop, Cannonball, Colossus, Cyclops, Emma Frost, Gambit, Rogue) and Sentinels joined the attack. Flaw threatened Psylocke and Elaine Grey unless Marvel Girl stood down, but Marvel Girl knocked him aside. Later, Colossus defeated Flaw. In the following battle, Elaine Grey was killed and the Commandos ended up surrendering.
(Uncanny X-Men#470) - After being incarcerated in Manhattan for a time, the Commandos escaped. They tracked Marvel Girl to Chicago, though they fought Bishop and Detective Charlotte Jones on their way out. Bishop was hit by Hypernova's blast , but absorbed the energy from the shot and took down Warshot and Flaw. The Death Commandos managed to utilize their orbiting Shi'ar ship to teleport to Chicago so they could attack Marvel Girl directly. They burst through the window of Dr. Maureen Lyszinski to attack her.
(Uncanny X-Men#471) - Marvel Girl fled with Maureen in her arms, blocking Flaw with a telekinetic shield as she went. She sent out a telepathic pulse to the Commandos, causing them severe psychic feedback. Blackcloak paged his ship for aid, but they told him to handle it himself. The X-Men (Bishop, Cannonball, Nightcrawler, Psylocke) and a Sentinel arrived. Flaw taunted Marvel Girl by shrugging off her blasts, then taunted her by assuming the shape of her best friend and grandmother, but Psylocke knocked him out with her psychic knife. The Shi'ar ship dropped a bomb that would have killed many, including the Commandos, for miles around, but the X-Men blocked it. The crew of the starship was apprehended, and the Commandos were presumably jailed again.
(X-Men: Emperor Vulcan#3 (fb) BTS) The Commandos began acting as the private guard to Chancellor Araki in Shi'ar space.
(X-Men: Emperor Vulcan#3) Araki entered with the Shi'ar Death Commandos for a meeting with Vulcan (current emperor of the Shi'ar), Deathbird, and the Guard (Gladiator, Manta, Nightside, Oracle, Starbolt, Titan, Warstar). Inside, they found Ka'ardum, Lilandra, and the Starjammers (Ch'od, Havok, Korvus, Marvel Girl, Polaris, Raza). Marvel Girl grew furious at seeing the Commandos and lashed out in a powerful attack, sending the Commandos scattering, and threatened Araki's life, even accusing him of running the secret order of the Shi'ar and ordering the death of her family, until Polaris stopped her. The Commandos soon departed peaceably.
(X-Men: Kingbreaker#1 (fb) - BTS) - When Vulcan focused on expanding the Shi'ar empire via conquest, he put the Imperial Guard on the front lines along with the Shi'ar Death Commandos, though many were reported killed in battle with Marvel Girl.
(War of Kings#4) - Gladiator and the Starjammers met with Councilor D'bek, with whom they interrupted a speech of Araki's in order to proclaim Lilandra ruler of the Shi'ar once again. They fought back Araki's secret order and Lilandra announced her return to rule with mighty cheers from the crowd. As Chandilar broke out in war around them, Lilandra, flanked by the Starjammers, headed toward the temple to claim her right to rule. The Shi'ar Death Commandos then attacked, Sega permeating the crowd with his clouds. Blackcloak killed D'bek with a thrown spear. Marvel Girl furiously hit Devo with a telekinetic blast as Polaris used magnetism to crush Krait's wings. Lilandra stabbed Offset with a spear as Korvus and Marvel Girl tried to get her to cover. As the Commandos began reigning death on the crowd, Gladiator quickly took down Hypernova and Warshot before Flaw attacked him. As Blackcloak held off Gladiator with his spear's energy blast, Araki ordered the others to kill Lilandra. One of the Fraternity of Raptors hid himself in the crowd and fired multiple shots, one of them killing Lilandra during the chaos. Commandos in this mission: Blackcloak, Devo, Flaw, Hypernova, Krait, Offset, Sega, Shell, and Warshot.
