Hunhow is a massive Sentient discovered deep beneath the oceanic surface of Uranus. Revealed to be the father of Natah, who had since defected from the Sentients to become the Lotus, Hunhow sets out to accomplish what his daughter ultimately refused to do: kill the Tenno.
Although he is dead by the time players encounter him, Hunhow's remains still house his living consciousness, allowing him to communicate with others whenever someone comes into contact with his remains. Even after the Old War the Lotus still fears him, and he still has Sentient drones (which he refers to as his "fragments", "children" or "body") at his disposal to do his bidding and is willing to forge a temporary alliance with the Stalker to attain his goals. The Lotus describes Hunhow as the individual mind of all his Sentient fighters, though it is unclear how many Sentient minds were active in the Old War. Regardless, Hunhow's influence speaks volumes, as Alad V claims he is a "bogeyman to the Corpus", indicating that they have either a great fear of him or believe that he no longer exists, possibly assigning him to legend.
As part of his research, Tyl Regor unearths Hunhow's remains from the depths of Uranus and reawakens his drones, news of which shocks the Lotus and forces her into hiding. After the Tenno and Teshin confront the Lotus about her past as Natah, they set out to seal Hunhow's tomb once more and delay his return. While the Tenno perform the deed, Hunhow communicates directly to the Lotus, disappointed at her apparent betrayal.
Setting out to complete the Lotus' failed task, Hunhow convinces the Stalker (using their mutual hatred of the Tenno) to serve as his agent and help him destroy the Tenno, giving the Stalker a greatsword forged from his remains. Fearing the worst, the Lotus (with assistance from Alad V) orders the Tenno to locate Hunhow's remains on Uranus in order to figure out her father's plans. Once the Tenno locate his remains however, the Lotus realizes that Hunhow has tricked her into giving away the location of the Reservoir - the source of the Tenno's power and their one weakness - which is hidden within the Void, a place impassable to Sentients. The Lotus sends the Tenno to the Void to save the Reservoir, later revealed to be located on the Earth's missing Moon. As the Tenno race to protect the Reservoir, Hunhow - speaking through the Stalker's sword - taunts the Tenno and the Lotus on their impending destruction.
During the siege, the Tenno uncover their true nature, and subsequently struggle to get back to their Landing Craft. However, the Stalker manages to infiltrate the Orbiter and ambush the Tenno. Just as the Tenno manage to secure the Somatic Link, the Stalker manages to impale the Warframe with Hunhow's sword and have the Operator at his mercy. Using the last of its strength, the Warframe manages to rip the sword apart, severing Hunhow's connection to the Stalker and forcing the latter to flee. What remains of the sword is kept as a trophy by the Tenno and does not seem to house his consciousness.
It is revealed Hunhow, having survived the Stalker's defeat, has infiltrated the Cephalon Weave, with his consciousness existing as a virus within Cephalon Suda. Intending to absorb the Cephalon data-weave and protect his drones from the environs from the Void, he gradually overtakes Suda's memories while the Tenno are helping her with her research into music. Recognizing that Suda's memories are invigorated by music, he seeks to destroy the Hydraulus musical organs Suda was seeking, and by the time the Tenno and Ordis manage to complete the song 's Anthem, Hunhow has almost finished overwriting Suda's personality and renders her deaf to the song. When Ordis enters into Suda's datascape in a desperate attempt to save her, and fails, the Tenno convinces a reluctant Cephalon Simaris to send them in themselves; therein Hunhow manifests as a menacing red outline of his original Sentient body. The Tenno remove the corrupted, dissonant notes he was using to prevent Suda from hearing the full song of Octavia and, with Ordis' and Simaris' assistance, allow Suda to remove Hunhow's invasive presence from her consciousness.
Early in the Old War's flashback, Hunhow appears, charging towards Lua as a flight of Tenno and Railjacks try to stop him. A barrage of Seeker Missiles strikes his head to little effect, before a squad of Condrix heading towards the Moon divert the sight away from him.
- During Octavia's Anthem, Hunhow makes reference to the "Naga Drums" first referenced by the Stalker in his Codex entry. These ceremonial Tenno drums were played during victory celebrations. Apparently they, along with Octavia's music, could "cross the gap" (presumably meaning the interstellar space between the Tau and Origin systems) and had a hand in defeating the Sentients during the Old War. Hunhow speaks of them "coordinating the slaughter of the Orokin across the gap", which refers to the moment following the end of the war when the Tenno 'betrayed' the Orokin by slaughtering them all. It is unknown if Hunhow is simply referencing the event, or implying that the Sentients somehow had a part in the Tenno turning on their masters.
- Within Cephalon Suda’s datascape during Octavia’s Anthem, Hunhow is actually spawned in the game as an entity. However, the model used for him is not the apparition of his body that the player sees, but rather a large, invisible Osprey. This Osprey model can be temporarily revealed using a Codex Scanner or Synthesis Scanner, via the outline placed on the model immediately following a successful scan. Note that this does not provide any information or unlocks in the codex.
- Interestingly there is a Sentinel Cosmetic called the "Hunhow Sentinel Mask", which predates Hunhow's introduction by a considerable margin (many of the early Sentinel Cosmetics were introduced in Update 7.8 (2013-04-19), roughly 2 years before Hunhow would make his debut). It is unknown if this was an intentional case of foreshadowing on the developers' part or not.
- Hunhow's name was revealed during TennoVIP 2015. Prior to this his name was unknown.
- Hunhow's name may be derived from Hun-Hunahpu, a Mayan god mentioned in the Popol Vuh. Hun-Hunahpu was beheaded and imprisoned in the Underworld along with his brother Vucub-Hunahpu, and their remains were recovered by Hun-Hunahpu's sons, Hunahpu and Xbalanque. This is similar to Hunhow's remains being trapped beneath Uranus' oceans, and some of his remains being reforged into and given to the Stalker.
- He seems to have the ability to use mind-control, as shown when the Tenno fights Stalker in the Orbiter as Stalker's energy color of his armor turned from blue to orange.
- He appears as a charred version of Lotus during the Natah quest.
- According to Natah during the Ropalolyst fight, he was "a farmer". Assuming this to be metaphor, it could allude to him being originally meant as a terraformer or agricultural system.
