Leandros is a supporting protagonist of Warhammer 40,000: Space Marine. He is a young Ultramarine of the command squad of the Ultramarines 2nd Company, who fought to save planet Graia from an Ork WAAAGH!, and then fought against the subsequent Chaos invasion led by Chaos Lord Nemeroth. He served under Captain Titus and Sergeant Sidonus, who he considered to be his friends and mentors, although Leandros' strict, by-the-book nature led him to ultimately hand Titus over to the Inquisition on suspicion of heresy.

Leandros was voiced by Noah Huntley.

Biography[]

Past[]

In the grim darkness of the far future, there is only war. Leandros was born sometime before M41, in the Ultramar System, home of the noble Ultramarines, hailed as the greatest Chapter of the Adeptus Astartes, the strongest defenders of the Imperium of Man. Leandros was recruited into the Ultramarines, and served in the Ultramarines 2nd Company. He was a very formal, by-the-book man, holding the Codex Astartes as sacred rules that must be followed to the letter, making him a soldier of little tact who tended to think little of the average human. Leandros was also prone to enthusiastically trying to prove his loyalty to the Codex Astartes, and would question any strategy that went against its doctrines.

By late M41, Leandros was part of a 2nd Company operation to destroy an invading Eldar Aspect Warriors on Beta-Arcturus. In the battle, Leandros was captured by the Eldar shortly after the company's captain, Trajan, managed to kill the commanding Eldar Autarch. Trajan led a rescue operation to retrieve Leandros, but was caught in an ambush and killed, so Ultramarine Demetrian Titus took command of the operation, driving the xenos out of Beta-Arcturus and rescuing Leandros. Titus was then promoted to captain of the 2nd Company by Chapter Master Marneus Calgar, and Leandros was recruited into the command squad of the 2nd Company, where he served alongside Captain Titus and veteran Sergeant Sidonus, who he soon came to see as close friends and mentors.

Warhammer 40,000: Space Marine[]

In late M41, planet Graia, an important Forge World of the Imperium, was invaded by an Ork WAAAGH!, a war on apocalyptic scale. Over a million Orks landed on Graia and quickly overwhelmed the planet's defenses, intent on capturing Imperial weaponry being developed on the planet, including a powerful Warlord-class Titan. As the planet was deemed to valuable to risk losing with an Exterminatus, and due to reinforcements taking too long to arrive, with the 203rd regiment of Cadian Shock Troops already deployed to Graia being unable to retake it, the Ultramarines 2nd Company were deployed to Graia to secure the Titan manufactorum before the Orks could get it. Captain Titus, with his battle-brothers Sidonus and Leandros, led the drop onto Graia, flying into the planet's atmosphere aboard a Thunderhawk gunship.

As the Thunderhawk descended, Leandros informed Titus that the planetary defense forces have been crippled, and orbital defense armaments were captured by the Orks. Sidonus sarcastically congratulated the Orks on their tactics, only for the Thunderhawk to be struck by Ork fire. An Ork Kill Kroozer was in the atmosphere, its anti-air turret shooting down all support craft that tried to get through. As such, Titus ordered the Thunderhawk to get to safety, having Leandros and Sidonus equip jump packs with him to get to the ground the fastest. Leandros objected, saying that the Codex Astartes did not support such an action, but Titus merely told Leandros to try to keep up, before jumping out of the gunship, followed by Leandros and Sidonus.

In the air, Leandros and Sidonus got separated from Titus, but still managed to land on the ground, while Titus first landed on the Ork Kill Kroozer, disabled it, and made it crash into the ground, riding the Kroozer down before making his way through the Ork-held territory. Leandros, in the meantime, had landed near the Kroozer crash site and shot his way through hordes of Orks, soon met with the landed Titus, where the two slaughtered another incoming Ork horde, although Leandros' helmet was shot off and critically damaged in the encounter. When all the Orks were killed, Leandros continued to fire at the corpse of an Ork he had already slain, until Titus stopped him by asking if he was wounded. Leandros appeared upset, saying that the Codex Astartes advised against jumping blindly into enemy territory the way Titus did, but Titus merely gave Leandros his helmet back and told him that there were benefits of thinking for oneself.

After brutally slaying all Orks they came across, the Ultramarines encountered still-living Imperial guardsmen, members of the 203rd Cadian regiment, who were still under assault from hordes of Orks. Titus and Leandros then met with Sidonus, who had landed by a ruined monument. With the squad reunited, Titus led Sidonus and Leandros in helping the guardsmen destroy the Ork attackers, including the Ork Nobs leading the charge. With the area temporarily secure, the Cadians thanked the Ultramarines for their help, in awe of being in the presence of the mighty Ultramarines, although Leandros was patronizing to the guardsmen, having lost his connection with regular humans following his ascension to an Astartes. Titus and his companions were then brought to 2nd Lieutenant Mira, the only surviving officer of the 203rd Cadian, who informed them that the Orks had captured a planetary defense cannon known as the Goliath, which they had been using to destroy any support crafts of the Imperial Guard, preventing more Cadian forces currently in orbit from landing.

Titus assured Mira that he would disable the Goliath, and accompanied by Mira and other guardsmen, Titus, Sidonus, and Leandros fought their way through the Ork hordes, finally breaching the domed structure housing the Goliath. As the Ultramarines entered, Mira and her forces stayed outside to continue holding the line, with Mira's hope in repelling the Ork invasion restored by the Ultramarines' presence. Titus soon retrieved a Melta-bomb within the structure, and after killing the Orks that infested the building, he had the bomb planted on a shell that was being loaded into the Goliath, which would make the gun explode once the shell was fired. However, some Orks got ahold of the shell on a higher level of the structure and removed it from the sequence, forcing Titus to kill those Orks as Sidonus and Leandros returned the shell to the firing sequence. Once the shell was loaded, it was quickly fired, but exploded within the barrel of the Goliath, blasting the weapon apart. With that, Valkyrie gunships of the Cadian Shock Troops began landing in orbit, bringing much-needed support to the 203rd Cadian.

With the gun emplacement down, Leandros accompanied Titus and Sidonus towards Manufactorum Ajakis, where a Warlord-class Titan was being held, as the orders to stop the Orks from capturing the Titan remained in effect. To reach the manufactorum, they found an Ork vehicle loaded onto a cargo railway system, meant to ram through the gates of Manufactorum Ajakis. Leandros and his companions boarded the vehicle and quickly killed the Orks aboard, with Titus picking up a plasma cannon emplacement and used it to shoot down an Ork dropship that engaged them, before forcing the train to crash. Once they disembarked from the wreckage, they soon came across a Servo-skull that was scanning corpses of guardsmen, seeking a living subject to deliver its message to. Once it found the Ultramarines, the Servo-skull relayed a message from Inquisitor Drogan, an Ordo Xenos Inquisitor on Graia, who had sent a desperate distress call when the Orks first invaded. The message spoke of the Orks closing in on the Titan manufactorum, seeking an experimental device, prompting the Ultramarines to double the pace to reach it. At the manufactorum, the Ultramarines met up with another surviving 203rd soldier, Corporal Antioch, who helped the Ultramarines gain entry into the complex.

Inside, Leandros and his companions were relieved to see the complex still free of Orks, and soon met with Inquisitor Drogan. Drogan told the Ultramarines of the facility's power source, a novel device of incredible power that could not be allowed to fall into Ork hands. As such, Drogan led Titus and his companions deeper into the facility, where Orks broke in through the pipes and attacked them. Regardless, Titus and his companions pressed forward, killing the Orks until they reached the chamber of the power source, where Titus descended alone to retrieve it, finding that the power source appeared to be a strange, hand-sized cylinder wreathed in mysterious energy. However, Grimskull himself broke into the chamber, fixated on the power source as a "shiny thing." Drogan warned that the power source was unstable and could blow, ordering Titus to manually insert it into its containment unit. Titus quickly killed several Orks that jumped into the chamber after him, and grabbed the unshielded power source, which unleashed a powerful, Warp-based explosion, although Titus managed to force the power source into its container as the blast engulfed the area. Leandros and Sidonus, who attempted to rush to Titus' aid, were blasted away by the explosion.

Titus survived the blast, emerging in the sewers under the facility with he power source in his possession. By then, Sidonus, Leandros, and Drogan had already evacuated the facility, with Drogan insisting that Titus couldn't have survived the blast. However, Leandros and Sidonus split off from Drogan anyways, with Sidonus discovering that Titus did indeed survive. Titus soon merged from the sewers, power source still secured, and reunited with Sidonus and Leandros. The three then met with Drogan again, who still believed that there was no way for Titus to have survived the blast, and revealed that the power source was actually Warp energy, something that Leandros exclaimed was heresy. Drogan insisted that his work was sanctioned by the Imperium, and that the power source could power a weapon known as the Psychic Scourge, a weapon capable of destroying the Orks. Sidonus then demanded to know why using the weapon wasn't the first resort, but Drogan explained that the weapon had never been test fired, and was capable of destroying the planet if things went wrong, saying that he needed proper sanction to use it. However, another Ork Rok, the asteroid-like invasion crafts that Orks used, crashed through a nearby building, with Titus noting that the increasing Ork forces should be sanction enough. With that, Drogan led the Ultramarines to the location of the Psychic Scourge, in the Kalkys facility. First, the Ultramarines met with Lieutenant Mira again in Bastion Primus, helping the 203rd Cadian secure some key positions from the Orks, allowing Mira to use Valkyrie gunships to ferry the Ultramarines companions to Kalkys.

Once they landed, Titus, Sidonus, and Leandros followed Drogan into the facility, where they were forced to destroy and disable the facility's security systems, which were set to shoot every living being, including them. Titus, Leandros, and Sidonus then had to fight off several Orks who broke into the facility, ensuring the weapon's power source was secure, before manually inserting the power source and traveling to the top of the towering facility, just as Grimskull caught up with them and breached the top of the facility. However, the Ultramarines still managed to fire the Psychic Scourge, which sent out a blast of Warp energy that struck an Orbital Spire specifically meant to channel the energy into a psychic blast that would destroy all the Orks. However, to the dismay of the Ultramarines, the weapon did not work, as the Orks rose after the initial shockwave passed. However, before the two sides could fight again, Warp rifts opened up behind the Orks, revealing Bloodletter Daemons that quickly tore the Orks apart, even overwhelming Grimskull and sending him plummeting off the top level.

Then, another Warp rift opened, and from the rift came Nemeroth, a grotesque Chaos Lord and Sorcerer clad in powerful Chaos Terminator Armor. Nemeroth promptly restrained the Ultramarines with his Warp powers, and Drogan then entered the room, nonchalantly approaching Nemeroth. To the horror of the Ultramarines, Drogan knelt before Nemeroth and said that his part of the plan had been completed. As it turns out, Leandros and his companions had been talking to a corpse all along, as the real Drogan had been killed by a Daemon just after sending his distress signal, with the Daemon using Drogan's body as a host ever since, rewiring the Psychic Scourge to open Warp rifts, and tricked the Ultramarines into being nothing more than pawns in Nemeroth's scheme.

Nemeroth then recalled the Daemon within Drogan's body, and noted that Titus had an abnormally strong resilience to the Warp, doubling the energies used in restraining Titus. However, before Nemeroth could try to kill the Ultramarines, Grimskull climbed back onto the top floor, declaring he wasn't so easy to kill, before attacking Nemeroth and tackling him off the tower once more, the two falling to the lower levels and freeing the Ultramarines, also leaving the Warp power source behind. Once freed, the Ultramarines began descending the tower, discovering platoons of Chaos Cultists and Chaos Marines of the Chosen of Nemeroth warband teleporting into the structure. After killing the Chaos soldiers, Leandros and his companions got outside, seeing the massive Warp storm forming over the Orbital Spire, which could allow a Chaos fleet to come through if it grew too large.

Titus, who had retrieved the Warp power source, once again held onto it as he led Sidonus and Leandros to Manufactorum Ajakis, with Titus planning to use the Titan within to destroy the Orbital Spire by supercharging its weaponry with the power source. However, Leandros then stopped and became increasingly unnerved by Titus' ability to withstand so much raw Warp energy, a sign of Chaos corruption. Sidonus rebuked Leandros for speaking out of line, but Leandros continued to protest, once again referring to the Codex Astartes, making Sidonus order him to be silent again. The three then pressed on despite Leandros' lingering doubts, reuniting with Lieutenant Mira and helping the 203rd Cadian fight through Chaos Marines, cultists, and Orks. However, Grimskull and his WAAAGH! Orks remained active, and kept hunting down Titus to get the power source. As such, Titus separated from his companions and engaged Grimskull in an outpost on the way to Manufactorum Ajakis, where Titus finally slew Grimskull. With Grimskull dead, the WAAAGH! fell into disarray, Orks scattering and being easily picked off by the 203rd Cadian. However, the threat from the Warp was still active, so Titus rejoined Sidonus and Leandros and took the rail system back to Manufactorum Ajakis, where the Titan, known as Invictus, was being crewed and loaded.

At Manufactorum Ajakis, the Ultramarines fought their way through Chaos forces, reaching Invictus. There, they released the Titan's mooring clamps, boarded Invictus, and Titus fended off Chaos forces who tried to stop the Titan's launch, before loading the power source into the Titan. With the power boost, Invictus unleashed a powerful blast that destroyed the Orbital Spire, preventing the Warp rift above it from growing larger, but did not close it. Additionally, the pieces of the tower remained suspended in defiance of gravity due to the Warp energy, but at that moment, Imperial reinforcements arrived in the form of a Liberation Fleet, including more Ultramarines and Space Marines of the Blood Ravens Chapter, all moving in to assault the Orbital Tower and clear it of heretics. Titus requested an evacuation ship, giving the power source to Sidonus and telling him to get it back to the Ultramarines homeworld of Macragge, where they could figure out how to neutralize it. Sidonus then went off on his own to reach the evacuation point, a landing pad, while Leandros stayed with Titus to hold off incoming Chaos forces.

After slaying scores of Daemons and Chaos Marines, Leandros and Titus then made their way to the landing pad, where Sidonus had been cornered by more of Nemeroth's forces, managing to just narrowly kill them. However, just as Leandros and Titus arrived, Nemeroth himself emerged from a Warp rift behind Sidonus and impaled Sidonus with his Lightning Claws, killing him. Nemeroth then used his Warp energies to restrain Leandros and the enraged Titus, taking the power source for himself and declaring that he would use it to ascend to a Daemon Prince, mockingly asking if Titus would be joining Chaos soon. Nemeroth then used another rift to leave, leaving Leandros and Titus with Sidonus' body. Leandros was distraught, lamenting the fact that he wasn't fast enough to save Sidonus, but Titus urged Leandros not to give into grief. Lieutenant Mira then arrived in a Valkyrie, and Titus explained what happened, and how he planned to kill Nemeroth during Nemeroth's transformation into a Daemon, when the Chaos Lord would be vulnerable. Leandros, however, vehemently disagreed with the plan, calling it suicide and claiming that whatever was behind Titus' Warp resilience could be used by Nemeroth to gain an advantage, although Leandros still denied that Titus could fall to heresy. Mira instead suggested that Titus could use that resilience to get close enough to Nemeroth to deliver a killing blow, and Titus agreed, ordering Leandros to guard Sidonus' body until the Apothecaries arrived.

With that, Titus left for the Orbital Spire, joining with Blood Ravens and other Ultramarines in a charge towards the Spire. As Titus ascended the Spire to engage Nemeroth, Leandros' concerns over Titus' unnatural ability finally overwhelmed his loyalty, and he contacted the Inquisition, reporting Titus on suspicion of heresy. Titus soon slew Nemeroth in single combat, and destroyed the power source, being returned to the ground by a Thunderhawk as the Warp rift finally closed. As Graia once again fell under Imperial control, Titus met with Lieutenant Mira, Leandros, and a few other Ultramarines. At that moment, an Inquisition craft landed, and an Inquisitor, Thrax, disembarked with a squad of Black Templar Space Marines.

Leandros tells Inquisitor Thrax of Titus' suspected heresy

Thrax questioned if Titus had turned to heresy, explaining the charges against him, much to Titus' anger. Thrax then ordered Titus to come with him, or else Thrax would have the Ultramarines 2nd Company and the 203rd Cadian charged with being complicit in heresy and dealt with accordingly. Leandros supported Thrax, saying that the Codex Astartes left no room for doubt concerning Chaos corruption, for only heretics could survive the touch of the Warp in the manner Titus did. Titus decided to go peacefully with the Inquisitor, as to preserve the honor of the Ultramarines and the lives of the 203rd Cadian, but not before telling Leandros that the true test of an Ultramarine was not following the letter of the Codex Astartes, but rather, choosing how to live by its values, a test that Leandros had failed. As Titus boarded Inquisitor Thrax' ship, Leandros, now wrought with shame, turned and walked away.

Warhammer 40,000: Space Marine 2[]

Leandros is now the Chaplain of the second company of the Ultramines, the elevated role among the Ultramarines thus with the having to maintain spiritual and moral purity with his battle brothers. He meets Titus again after Titus successfuly survives the Rubicon Surgery to become a Primaris Space Marine. He is still suspicious of Titus and does not reveal his identity to him until the end of the game.

Trivia[]

  • Leandros was originally relegated to an alternate universe of the mainstream Warhammer 40,000 timeline, as in the main canon, the Ultramarines 2nd Company is captained by Cato Sicarius in late M41. However, as of Space Marine II, he has been officially included in the mainstream Warhammer 40,000 timeline.
  • Despite following the Codex rigidly, he actually violates the Codex by calling the Inquistion on Titus as the Codex clearly states that if any of the battle brothers are suspected of heresy, they must be reported to the nearest chapter Chaplain or Librarian to investigate the potential for Chaos Taint, not the Inquisition.
    • Ironically, he becomes a Chaplain in the events of Warhammer 40,000: Space Marine 2.
  • Leandros' "by-the-book" behavior has gained a large notoriety over the years to the point fans would often ridicule and mock him, even creating communities to despise solely Leandros.
