An overlord

The overlord is a zerg flyer that provides control for lesser minions.

OverviewEdit

Overlord SC1 Art1

An overlord during the Great War

Overlords were evolved from the Gargantis proximae, a species of giant space-faring and semi-intelligent creatures[1] which volunteered to be assimilated in order to avoid extinction.[2] Once assimilated, they were used to help cerebrates control and coordinate their broods and scout using their enhanced senses.[1]

PsychologyEdit

The elongated appendages that hung from the underbellies of the Gargantis were evolved into an array of microscopic filaments that gather sensory and spatial information through intermittent pulses, which are then fed into the overlord's central nervous system. All data gathered is processed as fast as it is received, allowing overlords to navigate through any environment and relay tactical data to the Swarm.[3]

Overlords possess a large, bulbous brain which is protected by a heavily armored weave of bone and cartilage. It is a large organ, with millions of nerves and synaptic contacts.[3] The overlord's cerebral structure is complex with neural pathways woven throughout the body;[4] but is heavily concentrated in its lower section and legs. It is through this system that overlords relay commands to the Swarm.[3] The overlord's nerve system makes it a powerful psionic energy transmitter (its ability to broadcast psychic energy is unmatched) and to preserve this capability, the zerg only altered neurologically impotent parts from the Gargantis, including the carapace and pulmonary chambers. As a result, the overlord's core genetic matrix is atypically homogenous: over 90%. The minimal alterations also preserved memories;[4] ancient overlords, essentially assimilated Gargantis, regained their individuality upon becoming feral.[1] Dr. Talen Ayers proposed two theories as to why this was—one, the Gargantis had the properties the zerg desired, and as such, little modification of their genetic code was required. Two, the zerg are unwilling to meddle too deeply with the structural makeup of species that possess great psionic ability, knowing that even the slightest of changes can destroy this ability. He counted on the latter.[5]

Unlike most other zerg breeds, overlords have a greater capacity to act on their own judgement, though their mental flexibility is still severely limited.[6] Overlords typically only relay orders. They are technically capable of directly controlling lesser zerg, but only with extreme difficulty.[2] After Kerrigan's defeat at Char, some overlords attempted to form pockets of organized zerg in the same manner as broodmothers. However, this was a token effort, and most zerg regressed to a feral state.[7]

Overlords are fairly docile. Additional duties include tending to young larvae[8] and monitoring the progress of drones through a type of instinctive telepathy.[9]

PhysiologyEdit

Overlord SC-G Game1

An overlord

Overlords retain the thick outer shell of the Gargantis, and it changed little in the assimilation process;[3] Their exoskeletons are strong enough to resist a lightning strike.[10]

Overlords with the correct growth stimuli[1] can carry other zerg within hollows in their hides.[11] In this form they become deep-space transports[8]; the importance of their function is underlined by the sheer number of overlords found accompanying zerg forces.[1] As spacefaring creatures, an overlord's carapace pressurizes and seals whenever the creature flies through vacuum. Two species of unidentified symbiotic organisms seem to regulate these functions, though Dominion scientists have been unable to obtain any living samples—these organisms die within seconds if removed from their host overlord.[3]

Overlords use helium-filled gas sacs and a weak telekinetic psi-ability for lift and motive power.[12] This helium is generated through an efficient respiratory system distributed throughout the overlord's carapace. The excess helium is stored in thick sacs that contract and expand through rudimentary pulses, allowing overlords to regulate altitude and propulsion at will.[3] They move quite slowly however.[13]

By the Second Great War, overlords could disgorge creep to prepare the way for zerg conquests.[1] This creep is produced by the overlord liquifying its internal organs, with the creep being stored in multiple glands near the overlord's head. The process is instantaneous and takes place when space is needed for transportation of zerg ground strains. Overlords can regrow their organs at will, and can modify them to derive substance from inhospitable environments.[3] Also by the Second Great War, overlords could metamorphosize into overseers.[1]

In StarCraft II, the overlord provides control but does not provide detection. The overlord may evolve into the overseer which is a detector and spellcaster. Against protoss, it is recommended to keep overlords surrounded with strong anti-air defense as they are highly vulnerable targets for phoenixes used in the harass role.

The reason for the changes and the split between the overlord and overseer in terms of detection was that the zerg "were somewhat 'detectorific'" in StarCraft.[15]

AbilitiesEdit

The overlord can create a 2x2 patch of creep through an activated ability, the radius steadily expanding.[16]

A few overlords can create enough creep to cover a screen area.[17] The creep recedes in 30 seconds.[18]

A zerg player will typically have many overlords, and so can create creep over much of the map.[17]

Heart of the SwarmEdit

A special overlord skin is unlocked via leveling in Heart of the Swarm.[21]

When Kerrigan reaches a certain level overlords provide more control and are spawned instantly. This ability is called Improved Overlords.

Legacy of the VoidEdit

LegacyOfTheVoid SC2 Logo1

This article or section contains information from StarCraft II: Legacy of the Void.

The content may change substantially over time.

In Legacy of the Void, the overlord loses its ventral sacs upgrade. Instead, each overlord is upgraded individually to be able to transport units.[20]

DevelopmentEdit

The following section contains information from a previous version of StarCraft II which is no longer valid.

They regained the ability to transport units as of December 2008.[22]
Overlord SC2 DevRend1

Early StarCraft II overlord

Overlords used to have a slime ability, but that has been removed from the latest build.[23]

  • Slime (also known as "Corrupt Minerals")
    • The overlord could drop a non-attacking slime creature,[24] temporarily disabling resource nodes and xel'naga towers.[19][25] The minerals can be covered as they're being harvested, enabling raids which slow down an enemy's economy.[24] The creature must be killed before the minerals can be accessed.[24][15]
    • This ability took some time to "cast" and had a small cooldown timer.[24]

  24. 24.0 24.1 24.2 24.3 1) The tier 1 Overlord is very slow and does not have detection, though still essential for scouting throughout the game.

    2) They are two different abilities. In generating creep, the Overlord essentially unloads a bunch of creep straight to the ground below it, which expands. Corrupting minerals takes some time to fully cast, but it creates a non-attacking creature that takes over that resource, and needs to be killed before those minerals are able to be gathered. Furthermore, you can corrupt resources that are already being mined, introducing potential Overseer raids to slow the enemy's production.

    3)Neither abilities require energy. Creep generation does not have a cooldown whereas corrupt minerals has a small cooldown timer.
