{{for|the data of the monster in other variants|Mother Hydra}}
'''Mother Hydra''', {{brightgreen|H}}, is a '[[unique]]' [[monster]] that appears in [[dNetHack]], [[notdNetHack]] and [[notnotdNetHack]]. Her male counterpart is [[Father Dagon (dNetHack)|Father Dagon]].

Mother Hydra is a huge-sized and omnivorous female [[giant humanoid]] with a long neck that is an [[aquatic]] [[Giant (monster attribute)|giant]] and [[Great Old One]], and acts as an [[overlord]] to deep one-kind: like [[Deepest one (dNetHack)|deepest ones]], Mother Hydra is [[strong]] and [[thick-skinned]]; is [[amphibious]] and capable of [[swimming]]; has [[infravision]] and can be seen via [[infravision]]; can tear through [[web]]s and break open locked [[door]]s; will pick up [[weapon]]s, [[armor]], [[food]], [[gold]], and [[gem]]s that she comes across; and will [[follow]] a [[hero]] to other levels if she is adjacent. Mother Hydra cannot be made [[tame]], and can turn [[traitor]] if somehow tamed.

Seeing Mother Hydra can lower the hero's [[sanity]] and increase their [[insight]]. Witnessing Mother Hydra or Father Dagon reincarnate from the body of a deepest one can increase the hero's deep one-specific [[impurity]] with a {{frac|''n''}} chance (where ''n'' is the current impurity level)—reaching impurity levels of 1, 4 and 15 for this counter will also increase the hero's overall impurity.

Mother Hydra has four bite attacks, a weapon attack, an offhand weapon attack, and a [[passive attack]] that triggers on death and raises the current maximum HP of every other deep one-related monster that is on the current [[dungeon level]], increasing their [[monster level]] if necessary—this applies to the [[Deep one (dNetHack)|deep one]], [[Deeper one (dNetHack)|deeper one]] and deepest one, as well as Mother Hydra and Father Dagon, and Mother Hydra herself gains +8 HP when this passive from any deep one-related monster triggers. Mother Hydra has expert prowess in martial combat, and possesses [[sleep resistance]] and [[cold resistance]].

[[Eating]] the [[corpse]] or [[tin]] of Mother Hydra–or [[quaffing]] her [[Potion of blood (dNetHack)|blood]]–grants [[Temporary intrinsic|permanent sleep resistance]].

Mother Hydra can be [[Ward (dNetHack)|warded]] by a fully-reinforced [[User:Chris/dNetHack/Elder Sign|Elder Sign]].

==Generation==
Mother Hydra is always generated hostile. She is not a valid polymorph form or genocide target, and [[figurine]]s or [[statue]]s of her cannot be wished for.

Mother Hydra is always generated asleep on R'lyeh, the lowest floor of the Lost Cities and the [[Neutral Quest (dNetHack)|Neutral Quest]], where she is placed near the center of the rightmost section close to the river during level creation. A [[statue]] of Mother Hydra appears within the Temples of the Old Gods earlier in the branch, where it shares a square with the statue of Father Dagon—Mother Hydra's statue contains eight [[rubies]].

If Mother Hydra is killed, she will reincarnate by transforming from the earliest female deepest one that the hero has encountered outside of the future (i.e. the [[Anachrononaut quest]] and [[Android quest]]), with that deepest one's level and HP being raised to the appropriate values first.

Mother Hydra is [[generated with]] several items: a huge erosion-proofed +9 [[trident]]; a huge erosion-proofed +9 [[ranseur]]; a huge [[crossbow]] and 18 huge erosion-proofed +9 [[crossbow bolt]]s; a huge erosion-proofed +9 [[copper]] [[shield of reflection]]; two randomly-selected [[potion]]s from a potion of {{! of|acid|confusion|blindness|sleeping|or=1|paralysis}}, with acid having twice as much chance of being selected as the other potions; and two randomly-selected uncursed items from a potion of {{! of|invisibility|speed|confusion|gain level|extra healing|full healing|gain energy}}, or a [[scroll of remove curse]].

==History==
Mother Hydra first appears in the [[Lethe patch]] against [[NetHack 3.3.1]]

==Encyclopedia entry==
{{encyclopedia|
"Yield up enough sacrifices an' savage knick-knacks an'
harbourage in the taown when they wanted it, an' they'd let
well enough alone. Wudn't bother no strangers as might bear
tales aoutside - that is, withaout they got pryin'. All in
the band of the faithful - Order o' Dagon - an' the children
shud never die, but go back to the Mother Hydra an' Father
Dagon what we all come from once ... Ia! Ia! Cthulhu ..."
