Deathwatch - Watch Captains: Artemis, Captain of the Mortifactors - Watch Captain Artemis has the uncanny ability to sense and recognise alien incursions and influence on Imperial individuals and locations. He was originally a battle-brother of the Mortifactors Chapter but was brought into the Deathwatch to put his unusual abilities to use. Artemis commanded several Deathwatch kill-teams against the K'nib in the Donorian Sector. This was done at the request of the Imperial Guard's Kaslon Regiment. Artemis personally slew the K'nib Alcayde and ended their attack upon Imperial space, even though the credit was given to the Kaslon Regiment. He is quoted as saying: "Do not ask, 'Why kill the alien?' rather, ask, 'Why not?'" He wields a Space Marine bolter, a Power Sword, an assortment of grenades, and his power armour as wargear. His right arm is augmetic, lost in battle with the Tyranids and he possesses a bionic eye that has a bio-detection capability.Audin, Captain of the Mantis WarriorsBannon, Captain of the Imperial Fists - Bannon served as watch captain of a Deathwatch kill-team that was summoned to Tarsis Ultra in 999.M41, to assist Lord Inquisitor Kryptman in combating the Tyranids of Hive Fleet Leviathan. When a Lictor appeared in the Imperial city of Erebus, Bannon was ordered by the venerable Inquisitor to capture it alive. Following this deadly errand, Bannon next led his team on an extremely hazardous mission in order to power up a ground-based Defence Laser that was located to the rear area of the main Tyranid assault. Firing the Defence Laser in conjunction with the attack of the Ultramarines' Strike Cruiser Vae Victus allowed the defending forces to destroy one of the two remaining Tyranid Hive Ships that controlled the swarm. Ultimately, Bannon's position would be overrun by attacking Tyranids, and so his Deathwatch team was extracted by a Thunderhawk gunship. Bannon was the last to be extracted, but as he was being lifted aboard by a rappel cable, his leg was seized by a monstrous Tyranid bioform. Refusing to allow his team to be killed, Bannon bravely cut his line, sacrificing himself. Surviving witnesses report last seeing Bannon disappear beneath a tide of chitin and claws, armed with only his Combat Blade, fighting to the last. Following his death, command of the kill-team briefly fell to Brother Henghast, but was later assumed by Ultramarines 4th Company Captain Uriel Ventris for the team's assault on the final Hive Ship.Barradan - Barradan is one of the few Primaris Space Marines to become a Deathwatch Watch Captain. Barradan serves in Fort Excalibris, and is one of the few Primaris Space Marines to have risen to the rank of watch captain in the Era Indomitus. He has already distinguished himself in many battles with xenos forces. Such promotions have proved strategically beneficial, for with their intrinsic understanding of Primaris infantry forces and Repulsor tanks, these watch captains have helped to fully integrate these weapons into the Deathwatch's arsenal.Bron, Captain of the Dark Sons - When Captain Bron was mortally wounded during a confrontation with a Slaugth Overseer in the Black Reef, he recommended that the Marines Errant Battle-Brother Kail Vibius be promoted to the rank of Watch Captain in his stead, a role he has held ever since.Cynewolf, Captain of the Space WolvesEsteban de Dominova, Captain of the Crimson Fists - An intense, laconic, sallow-faced battle-brother with pale, colourless eyes prone to brooding silences and piercing glares, Watch Captain de Dominova hails from the Crimson Fists Chapter of the Adeptus Astartes. Currently serving his fifth Vigil with the Jericho Reach Deathwatch, the Watch Captain is a highly respected Apothecary whose prowess in the operating theatre has reached near mythic proportions among the kill-teams with which he has served. Indeed, many battle-brothers currently serving a vigil in the Jericho Reach owe their limbs, if not their very lives, to his quick thinking and sure hands. Along with his prodigious medical skills, and the usual finely honed warrior abilities possessed by every battle-brother, Watch Captain de Dominova is also a noted xenobiologist who is known to work closely with the Ordo Xenos and the Mechanicus' Magos Biologis in various capacities.Jerron, Captain of the UltramarinesQuiron Octavius, Captain of the Imperial Fists (KIA) - Instrumental in combating a splinter hive fleet of Tyranids near the Herodian IV Warp Gate. He was later slain by a Drukhari Talos Pain Engine.Andar Scarion, Captain of the Astral Claws - Andar Scarion is a member of the Astral Claws Space Marine Chapter who was seconded to the Jericho Reach to serve in the Deathwatch. His arrival was the cause of much controversy due to his Chapter's questionable actions in the decades before the outbreak of the Badab War. Nevertheless, Scarion was allowed to commence his Vigil with the Deathwatch and served for over five decades with honour, achieving the rank of Watch Captain. Like his Chapter Master Lufgt Huron, Scarion is a proud and ruthless warrior with a keen grasp of strategy and military politics, and has proven himself to be a valuable asset in liaising with the Achilus Crusade's officers. He expects the kill-teams under his command to perform to the most exacting of standards and does not tolerate laxity, weakness or failure. As is common to many of his Chapter, Scarion regards non-Astartes with a mixture of scorn and pity, holding that the Astartes ideal is fundamentally superior to the physical and especially moral frailty of the common run of Humanity. He masks this arrogance well when political goals require it, but discards the façade when amongst other Astartes, seeing little issue with collateral damage amongst Human allies whom he regards as inherently expendable.Uriel Ventris, Captain of the Ultramarines 4th Company - Uriel Ventris temporarily assumed command of a Deathwatch kill-team, replacing Imperial Fists' Captain Bannon, when he was killed during the defence of the world of Tarsis Ultra from the Tyranids. Uriel Ventris led the Deathwatch kill-team into a Tyranid Hive Ship to kill the hive fleet's Norn-Queen with a gene-poison derived from the genome of a Lictor, which was genetically-engineered to induce hyper-evolution in any Tyranid affected by it. Ventris was later exiled from the Ultramarines for breaking the Codex Astartes, condemned to fulfill a Death Oath in the Eye of Terror against the Iron Warriors. Ventris completed this quest and returned to honourable service with his Chapter.Kail Vibius, Captain of the Marines Errant - Kail Vibius is a Marines Errant battle-brother who serves as a watch captain in the Deathwatch. Vibius has a burning desire for vengeance against xenos, which has marked him out even amongst the alien-hunters of the Deathwatch. During the Corinth Crusade, Vibius and a squad of his fellow Marines Errant were captured by the vile Drukhari and taken into the Webway to the dark realm of Commorragh. Surviving their cruel treatment at the hands of his xenos captors, Vibius bided his time until he was able to seize the opportunity to escape, leading a slave revolt against his surprised captors. Eventually the Space Marines fought their way to freedom and returned to the Imperium. Vibius was nominated for the honour of representing his Chapter in the Deathwatch, and rose swiftly through the ranks until he led his own kill-team. When his former commander, Captain Bron of the Dark Sons Chapter, was mortally wounded, he recommended Vibius be promoted to the rank of Watch Captain in his stead, a role he has held ever since.Caltanix, Captain of the Black Templars - Caltanix was the commander of Kill-team Caltanix of the Furor Shield Watch Fortress and along with Kill-teams Artemis and Krycses particpated in the boarding of Gorsnik Magash's flagship during the defence of the Kurbynola System. Caltanix and almost his entire kill-team perished during the assault.Ska Mordentodt, Deathwatch Black Shield - Distant and forbidding, even to the Astartes under his command, Watch Captain Mordentodt commands a Watch Company of the watch fortress at Zarabek and the kill-teams housed within. Upon receipt of reports of pirate attacks using Aeldari weapons from the Elkinian Reach, Mordentodt dispatched Kill-Team Courlanth to investigate what turned out to be an asteroid base in the Teramus System commanded by the pirate Arlon Buke. However, Mordentodt's real goal was to secure an entryway into the lair of the Drukhari Kabal of the Crimson Blossom which was colloborating with Buke's pirates in return for new supplies of Human slaves. Using Teleport Homers carried by Courlanth and his team without knowledge of Mordentodt's goals, Mordentodt and a Terminator Assault Squad teleported into the kabal's lair within Buke's asteroid base and rescued Courlanth and the surviving members of his kill-team while slaughtering most of the pirates and the kabal's upper leadership, including its archon Gharax.Lyone of the Novamarines - Prior to his secondment to the watch fortress of Null Breach in the Segmentum Solar, Lyone was a Primaris Intercessor of the Novamarines Chapter. He aided the kill-teams commanded by Watch Captain Daxis in their battles against the Orks of the world of Calverna and within six solar months of joining the Deathwatch, he became fearfully known to the Orks as "Da Black Butcha," while his battle-brothers began to call him "Orksbane." When Watch Captain Daxis was later killed in battle by a rampaging Squiggoth, Lyone single-handily killed the massive creature with pinpoint fire. This earned him Daxis' former command and Lyone has excelled as a watch captain ever since, one of the first of the Primaris Marines to achieve this rank in the Deathwatch.
