Release Date: December 22nd, 2016
Epitome of the endlessly evolving Infestation, Nidus bends the vile corruption to his will, mutates his genetic potency to adapt and assimilates his victims with an insatiable parasitic hunger. Nidus and his strain developed in .

==Lore==
Little is known about the history of the Nidus Warframe aside from its Orokin era origins. However, the Myconians have apparently used information learned from their time possessing the relic, the Nidus blueprint, to produce the Triuna, an infection passed down from generation to generation, which the Infestation fears due to the hybrid nature of the resulting host, allowing the Myconians to harvest Infested flesh as part of their livelihood.
Nidus has a mysterious connection with the Helminth being that resides in the Orbiter, being the only Warframe that can purposely command the Helminth to infect him with the Helminth Virus; the extent of this relationship is currently unknown.
==Notes==
*Nidus has unique interactions due to his lack of shields:
**The shield reduction from the Decaying Dragon Key has no effect, allowing Nidus to carry it without issue.
**The No Shields Nightmare Mode condition has no effect.
**Cryogenic Leakage has no effect on his nonexistent shields. His friction is still affected however.
**The increased shield damage from has no effect. Energy drain and HUD disruption still occurs however.
** and will always give energy when damage is taken.
**The Hijack objective will drain his health instead in order to move.
**He cannot receive overshields, or gain shields from allied Shield Ospreys, Orokin Drones, 's , or 's .
**His lack of shields prevents him from receiving shield gating.
*Nidus can uniquely access the Orbiter's Helminth Infirmary without the Helminth Segment prerequisite. If he sits in the infirmary's chair, he will be injected with the "Helminth Virus", forming an Infested cyst on the left side of his neck after 24 hours and grows to full size after 7 days, while simultaneously "awakening" the Helminth which will begin to communicate to the Tenno. Nidus can also spread this virus to other players he comes into contact with in combat and in a Clan Dojo or Orbiter, causing the cyst to grow on their Warframe, and those Warframes can also further propagate the virus.
**The injection will only occur once, and will not happen again to additionally built Nidus. However, Nidus can still receive the cyst from another infected player.
*When entering the Helminth room, Nidus will automatically switch to his fully infested form (as he appears with 10 Mutation Stacks). As he leaves the room, he will revert to his normal appearance.
*Nidus' appearance changes as he accumulates Mutation Stacks:
**At 3 stacks, tendrils will protrude from his neck and upper spine, while the carapace around his ribs will open.
**At 5 and 7 stacks respectively, the carapace around his thighs and arms will open to reveal more infested flesh and tendrils beneath.
**At 10 stacks, the sides of his head extend outward to form a pair of horns, also exposing many more tendrils.
==Trivia==
*The word nidus (Latin root: "nest") is defined as the site of origin for disease or bacteria or a place where bacteria multiplies.
*Nidus is the first Warframe to use as a blueprint ingredient.
*Nidus is the second Warframe after to have no base shields whatsoever.
*Nidus is also the first Warframe to use another type of ability resource besides energy, in the form of Mutation stacks.
**This trend would later be followed by , , , , , and .
*Nidus is the first and only Warframe to innately regenerate Health.
*Nidus is the first frame to have extra stat bonuses when leveling up.
*The screech of Nidus' fourth ability was done by Digital Extremes sound designer, Willem Schonken.Devstream #102
