Infested : Mutalist Alad V


Controlled by the Infested and corrupt with power, Mutalist Alad V is the boss of Eris introduced in Update 15.5. To fight him, players need to craft the Mutalist Alad V Assassinate Key with the blueprint awarded from completing the Patient Zero quest.

Infested : Lephantis


Lephantis (previously known as J-2000 Golem) is a massive Infested boss introduced in Update 10. It was originally going to replace the now retired J3-Golem boss but was moved to the Orokin Derelict tileset instead. Lephantis requires players to craft a special Derelict Assassination key, which requires five Golem Nav Coordinates; items only obtainable though Derelict missions; missions which require regular Nav Coordinates found in normal missions.

Infested : Phorid


Phorid is an infested boss, found when an infested invasion manages to “Infest” the boss node. After defeating it and finishing the mission, you receive a Nyx Helmet, Chassis, or Systems Blueprint. Upon death, Phorid has a chance of dropping rare Resources of the planet he appears on.

Corpus : Sgt. Nef Anyo

Sgt. Nef Anyo is the final boss of Mars system, in charge of the Corpus solar rail systems, and has been using them to obtain Cryopods with dormant Warframes for resale to rogue scientists and splinter groups. When confronted by the player during the mission, he has a very aggressive tone towards the Tenno and warns the player that they are making a fatal mistake by attempting his assassination. He also may demand information regarding Orokin secrets, or like Tyl Regor, make fun of the player’s Warframe or teammates.

Corpus : Raptor


The Raptor is a Corpus Boss found in the Europa system, and the only flying Corpus boss in the game. It has very high stats and heavy hitting weapons, including launching high damage missiles that seek players, deploying mines and firing explosive laser bolts, making fighting in the open a difficult task. It was marked for assassination for being a high threat risk, as more models of this proxy could result in dangerous repercussions.

Corpus : Lynx


The Lynx is a miniboss that is encountered in certain Orokin Sabotage tiers that feature Corpus enemies, acting as the main miniboss from which the mission’s Void Key drops from. It resembles a smaller Jackal with blue armor, and has the ability to deploy Osprey drones and Turrets to assist it in combat.

Corpus : Jackal


Jackal is the final boss of the Venus system, and represents the first Corpus boss that players encounter. Although a more bulky and old model compared to more recent Corpus robotics, the Jackal possesses invulnerable shields, a giant shockwave ability to knock players down, and one of the most powerful corpus weapons, the Plasma Grenade Cluster. Dissected models of the Jackal can be found in some Grineer tilesets, either showing that the Grineer have interest in utilizing Corpus technology, or that they have simply purchased merchandise.
