You've called this a disease? Heh, an Infestation? Well, I call it unity! One army under me! Welcome to your new species!
—Mutalist Alad V
For his normal version, see Alad V.

Mutalist Alad V is a version of Alad V mutated and twisted by the Infestation. From his base on Eris, Alad V invented the Mutalist Strain, allowing the Infested to infect inorganic robotics and weaponry, before succumbing to the Infestation himself.

Upon completion of his assassination mission, player will receive the MesaIcon272 Mesa Chassis, Neuroptics, or Systems blueprint.

Mutalist Alad V Assassinate Key[]

In order to gain mission access to Mutalist Alad V, players must possess a Mutalist Alad V Assassinate Key, whose blueprint is awarded from the Patient Zero quest. One of the main components of the Key is MutalistAladVNavCoordinate Mutalist Alad V Nav Coordinate, which is a battle pay reward from Infested Invasions, Hyf/Terrorem (Defense/Survival, Deimos) reward, or resource caches from Hive Sabotage.

The key unlocks a node called "Mutalist Alad V Assassinate" on Eris. Only the host will have their key consumed on mission completion.

For his lore before his infestation, see Alad V.


Mutalist Alad V was once one of the Corpus Board of Directors, portrayed as a man with a deep interest with the power of the Tenno which led to his various conflicts with the opposing factions, such as capturing a Warframe to complete his Zanuka Project. As a man with deep knowledge, he was able to evolve the Infestation further and eventually became the first man unassociated with the Tenno to control a Warframe, albeit at the cost of his own sanity—becoming the Infested himself.

Suspicious Shipments[]

After the events of The Hunt For Alad V, The Lotus discovered several Corpus ships that were traveling well outside usual shipping routes. These ships were heavily armored, and used several measures to keep themselves hidden from prying eyes. Suspicious about their purpose, Lotus sent the Tenno to investigate these ships and their mysterious cargo.

The Tenno discovered that many of these ships contained samples of Infested tissue, heavily guarded by Corpus platoons, though some of these ships have suffered containment breaches and have been overrun with the Infested. Alad contacts the Tenno during their investigations, explaining that he disagrees with the Corpus ban on Infested Biotechnology, and has decided to focus his resources on this forbidden line of research.

Operation Breeding Grounds[]

The Lotus learns that Alad's experiments have allowed the Infestation to evolve, allowing it to infect and corrupt inorganic beings. Lotus also discovered that Alad has also engineered Infested Hives as a means of directing the spread of the Infested, as these hives can quickly corrupt new ships or colonies almost immediately.

After hearing word of a massive Infestation outbreak near Eris, Lotus ordered the Tenno to intercept the Infested ships and destroy the hives in order to halt the outbreak, fearing that the newly evolved strain would quickly overrun the system if left unchecked.

Although the Tenno succeeded in stopping the outbreak, Alad sent out one last message that mocked the Tenno's efforts, claiming that their actions have left Alad with the hardiest, most vicious strains at his disposal.

Operation: Mutalist Incursions[]

With the evolved Infested at his disposal, Alad unveiled his plan to unleash a new "Mutalist Empire," infecting Tenno, Grineer, and Corpus alike in an attempt to unify and subordinate them. At this point The Lotus believes that the Infestation has corrupted Alad's mind, describing him as the Infested itself. From there, Mutalist Infestations would periodically surface across the Solar System, and the Tenno were tasked to purge them with the help of the Corpus and the Grineer. Through the valiant and combined effort of the three factions, the Mutalist Infestations were quickly pushed back into minimum, but ultimately failed to fully exterminate the new breeds and so remained a permanent threat to the system.

Patient Zero[]

The Lotus also directed the Tenno to locate Alad and destroy his research labs. During their searches, Alad, now hybridized with Infested tissue, contacts the Tenno and reveals that he has another Warframe in his possession, and plans to infuse it with Infested tissue. The search continues, and as they have located his research labs, they encounter the Infested Warframe - the epitome of Alad V's Mutalist Infestation.

Despite Alad V's laboratory being destroyed, he expresses no grudge towards the Tenno and instead announces his disappointment at them, remarking that this was a chance for them to redeem their past mistake.

Operation: Tubemen of Regor[]

Alad V and Nef Anyo duel for the potential cure to Alad's Infestation, which is found within Tyl Regor's ocean labs. As Alad V describes, he wishes the Tenno to obtain Tyl Regor's research before sabotaging the lab to potentially find himself a cure of the plague, to purify his Infested self and to redeem himself of his mistake. Nef Anyo, however, sees his plea to the Lotus as a threat to his position in the Corpus board and immediately broadcasts his alternate proposition to pay the Tenno to destroy Tyl Regor's lab, wanting to prevent Alad V from obtaining the cure and regain power in the board. As both sides offers the locations of the underwater laboratoriums to do their willing, the Lotus refuses to sway the Tenno into a specific choice, and it is ultimately up to themselves to decide which of the two is the lesser evil.


Like the Mutalist Osprey, half of Alad is still his original self, but Infested mass has spread all over his other arm, leg, and body. No longer accompanied by his Zanuka, Alad V is forced to fend for himself with a Paracyst Paracyst rifle.


Paracyst Rifle[]

Alad V often fires in short bursts that deal high DmgToxinSmall64 Toxin damage, bypassing shields. It is capable of applying a DmgToxinSmall64 Toxin proc, which will often deal high and fatal DoT to Tenno with low health not equipped with Mod TT 20px Antitoxin, and can also apply a DmgCorrosiveSmall64 Corrosive proc.

Nanite Aura[]

Alad V is shrouded in a swarm of nanites, slightly damaging nearby Tenno if they are too close.

Infested Barrier[]


Alad V removes his collar and deploys it on the ground as a temporary cover to hide and shoot behind. Weapons with punch through can penetrate the barrier and damage Alad. Once he has taken enough damage, he will re-equip his collar.

Biomass Launcher[]

While the Infested Barrier is active, it will periodically shoot out multiple projectiles that can deal and proc DmgRadiationSmall64 Radiation damage.

Flare Burst[]

If any Tenno wander too close to Alad V when he deploys the Infested Barrier or when the Barrier is active, the Barrier will explode in a burst of flame, knocking back and damaging anyone who is too close.

Collar Beam[]

Alad V removes his collar and releases a continuous electrical beam that deals very high damage at a rapid rate. If his target is out of range or behind cover or Alad has taken enough damage, he will stop the attack and reequip his collar.

Collar Throw/Mind Control[]

Alad V removes his collar and throws it similarly to a Glaive Glaive at a random Tenno. However, the collar does not bounce across surfaces, and can track and follow fleeing Tenno. If the collar connects to a Tenno, it will be forced under Alad V's will, and will automatically attack allies. The controlled Tenno is marked by an orange link to Alad, and can be rescued by damaging Alad enough. If fighting Alad V alone, the collar will explode on impact, staggering the Tenno and depleting their shields. Shields will be depleted and the Tenno will be staggered even if Rhino's Iron Skin is active, although Iron Skin will remain untouched and will still protect Rhino's health.

This attack can be dodged by performing a sidespring at the last moment before the collar makes contact or through shooting at it mid-air. It can also be negated by a Nyx's first and third abilities. The collar will remain attached, however the affected Tenno will act as if it were an ordinary enemy under Nyx's influence.

Toxin Resistance[]

Alad V possesses an innate 70% damage reduction to DmgToxinSmall64 Toxin damage.


  • Since Alad is still susceptible to status procs while invulnerable, a player can use a high-status beam weapon to stack DmgFireSmall64 Heat on him. Once he takes off his collar, the accumulated damage from the stack will all be dealt at once.
    • While you can still stack DmgToxinSmall64 Toxin, DmgGasSmall64 Gas, or DmgSlashSmall64 Slash, Heat is the only proc that can stack indefinitely, and will also refresh it's entire duration every time a new stack is added.
    • Some optimal weapons for this include Gaze Gaze (Primary), Nukor Nukor(KuvaNukor Kuva), and Cycron Cycron(TenetCycron Tenet).
  • While Alad is using his shield, BansheeIcon272 Banshee can Silence130xWhite Silence him, making Alad permanently vulnerable and easy to kill.
  • Alad V is completely invulnerable to all types of damage while his collar is equipped. Alad V becomes vulnerable when he attempts to attack back with his collar. When another Tenno is controlled, the others should concentrate fire on Alad V while avoiding attacks from the mind-controlled Tenno. DmgSlashSmall64 Slash and DmgToxinSmall64 Toxin attacks can still proc even when Alad is invulnerable, though the damage is only dealt when his collar is removed.
  • Since Alad V isn't status immune, stripping his armor (with DmgCorrosiveSmall64 Corrosive procs for instance) is a good option, especially in Sorties.
  • Throughout the battle, various Infested units will spawn in, increasing the danger level of the mission when Tar-Mutalist MOAs attempt to slow the Tenno down and Swarm-Mutalist MOAs apply nanite swarms across the area. A powerful melee weapon with Mod TT 20px Life Strike can help replenish the DmgToxinSmall64 Toxin damage dealt by Alad V.
  • Try not to have weapons too powerful as you could wipe out your team very quickly if you become controlled by Alad.
  • AshIcon272 Ash can wipe out his entire team very quickly with his fourth ability if mind controlled.
  • EquinoxIcon272 Equinox is an option if playing with others because Maim will discharge if Equinox is controlled, potentially dealing fatal damage to Alad.
  • While playing solo, ValkyrIcon272 Valkyr's Hysteria130xWhite Hysteria can swiftly take down Alad V with ease.
  • LokiIcon272 Loki can kill Alad V in seconds while invisible, given that a high damage bow weapon is equipped.
  • HarrowIcon272 Harrow's Condemn130xWhite Condemn can freeze Alad V at any stages, use it after he throws the collar to give teammates a good amount of time to finish him off.
  • KhoraIcon272 Khora's Ensnare130xWhite Ensnare can trap Alad V when he removes his collar, enabling allies or (if playing solo) yourself more time to damage him. A high damage Whipclaw130xWhite Whipclaw build can finish him with ease.
  • IvaraIcon272 Ivara's Artemis bow can one-shot Alad V when fired from Prowl for bonus headshot damage. See Ivara's ability details for a guide on maximizing Artemis's damage.
  • TrinityIcon272 Trinity with Transient Fortitude, Fleeting Expertise and Blind Rage can use EnergyVampire130xWhite Energy Vampire to deal true damage up to 25% of Alad V's total HP in 1.125 second. Because Energy Vampire bypasses shield and Alad V at sortie level has tremendous amount of HP, this can out-damage any weapon a Tenno can use, as almost no weapon can exploit such a short window of vulnerability while dealing this immense DPS and bypassing shield at the same time. However, one should take care if bringing Trinity, as Alad V can mind control her and use her Blessing130xWhite Blessing to fully heal himself as well as give him a damage resistance buff.
  • A good combination for soloing Mutalist Alad V is to use Nova combined with a high burst damage weapon such as a Tigris, energy restores and a Clem clone. When engaging Alad, drop a Clem clone, move towards Alad and use Molecular Prime. First of all, Alad will become obsessed with Clem and pretty much ignore the player. This doesn't work with other specters however. Secondly, the time it takes for Alad to remove his collar becoming vulnerable and replacing it is very, very, very short. Molecular Prime slows this down giving the player a greater opportunity to damage Alad.
  • If a player has Void Strike and sufficient focus progress a viable strategy, particularly when soloing in Steel Path, is to wait in void form until Alad V deploys his collar as a ring around him, then transfer in and deal a headshot with a high damage single-shot weapon such as Rubico Prime.


  • Mutalist Alad V has twice the armor and over twice the health of his previous non-Infested self.
  • Occasionally, Grineer troops will invade during the mission, gradually taking over the Infested presence and even assisting in fighting against Alad V, though they will still remain hostile to any Tenno.
  • Alad V can mind control Specters, which are arguably a less dangerous threat than fellow players.


  • After Alad V's mind control, players may fall through the map upon recovery.
  • Occasionally after spawning, he may stand still and become non-hostile, refusing to remove his collar, thus making him invincible until the mission is restarted.
  • When Alad V Spawns there is a chance your screen will go very dark. Falling out of bounds (or the map) and letting the game respawn you seems to fix this.
  • If you are mind controlled while reviving an ally, the ally will continue to be revived, regardless of you being there.
  • Upon death, a mind control beam may be linked between players while no one is actually mind controlled.
  • When viewed outside of his own Codex entry (Ex. Boiler) Alad V will not have his headgear.
  • In one of the corners, after using any ability there is a high chance Alad V will clip through the map, making the fight impossible unless restarted.
    • If you have a LokiIcon272 Loki in your squad and have line of sight of Alad V, it's possible to use SwitchTeleport130xWhite Switch Teleport to free Alad V and resume the fight.
  • When Alad V uses mind control on a ValkyrIcon272 Valkyr and said Valkyr uses Warcry130xWhite Warcry, any players hit will be slowed permanently, even after the ability's duration ends and/or Valkyr is freed from mind control. This can be fixed by dying.
    • This effect also applies to the casting Valkyr, usually allowing them to permanently gain increased melee speed, which can prove beneficial to dealing with the large number of infested enemies in the area.
  • In public sessions with higher ping, Alad V will rarely, if ever, fire his Paracyst Paracyst at players, making him relatively harmless outside of his collar attacks.
  • Occasionally, when Alad V mind controlls you, your Warframe may 'duplicate;' one will begin attacking other players as intended with the camera following it, while the other will continue to remain under your control. The second Warframe is only visible to you, however, and cannot interact with anything until you're freed from mind control, causing the first one to dissapear.
    • This is likely due to how the game handles the mind control effect, as it simply spawns an enemy specter of the mind-controlled player while hiding the player themselves until they are freed from the effect, thus creating the illusion of the player's Warframe being taken over by Alad V.


  • Alad V is the first boss to become Infested.
  • Despite his radically altered form, he still possesses the same mod drops as his original self.
  • Like the Specter, when Alad V controls a player's Warframe, their energy color will be bright cyan for their Warframe, Abilities, and their Weapons.
  • Much like his uninfested self during the Gradivus Dilemma, Mutalist Alad V set up a forum account that he used to argue with Nef Anyo as part of Operation: Tubemen of Regor.
