Visually, the mothership only underwent a single revision during development. After the initial creation and some minor proportion adjustments, it stayed unchanged for a few years. When it came round to the final art pass, it was mainly to make smoother surfaces and more distinct objects thanks to the improved polycounts.
"Scorch the ground beneath the Mothership for 15 seconds, causing damage to enemy ground units below." Deals massive damage to an area directly below the mothership's position (ideal for destroying buildings and slow-moving targets such as siege tanks) over a period of time. It has no effect on air units.
It gains the Stasis ability, which freezes air units in place for 20 seconds. Vortex now affects only ground units. In addition, Vortex will only target one non-massive unit, and will kill that unit.
The energy cost of mass recall for both motherships and mothership cores was decreased in Legacy of the Void. The developers noted that protoss struggled in base defense, so the cost was reduced, making it easier to defend multiple bases, and to play more aggressively in the early/mid stages of the game.
In Patch 4.0, the mothership core was remove, so motherships were returned to being built from the nexus. As Mass Recall was moved to the Nexus, the mothership was given a separate ability named Strategic Recall, which functioned the same but did not share a cooldown with Mass Recall.
Summons all units in target area (6.5) owned by the mothership's player to the mothership's location.
↑ In the current build, only the Queen is 'unique' (only limited to 1 per Zerg player at any given time). The Thor is currently the Terran's primary ground to air mechanized unit. More than one Mothership can also be built, though they are quite expensive in cost. Karune. 2008-03-24. Unique?. Battle.net StarCraft II General Discussion Forum. Accessed 2008-03-24.
↑1. It's a Terran vs. Zerg game. I promise nothing on what week it will come out. You must continue to suffer and wait.
2. I don't know much about these.
3. We have Void Ray, Phoenix, Mothership, Carrier, Warp Prism, Observer. Mothership moves slowly, can teleport to any Protoss building, can do huge damage to a single target with Vortex and cloaks everything nearby on the ground (including buildings). Mothership is build-limit-one. This is done primarily for balance reasons. You use her as a base defense that can be anywhere you want in a flash. Sometimes you push into an enemy base with her. Testing on her remains a pain because she is so high-tech we don't see her in a lot of games. Right now she is reasonably cool, but we are not in love with her yet.
4. I cannot.
↑You can cloak your Mothership with your Dark Pylon's Null Shield.
In this case, the enemy can't see anything in your base without a Detecting unit. Cydra. 2009-03-02. Bue: Question. Battle.net StarCraft II General Discussion Forum. Accessed 2009-03-02.
↑ 12.012.1Mothership's ability:
Cloaking Field(Passive): cloaks nearby ground units and structures
Vortex: creates a gravity vortex that incapacitates units in the target area
Wormhole Transit: allows the Mothership to instantly travel to Protoss building Cydra. 2009-04-30. . Battle.net StarCraft II General Discussion Forum. Accessed 2009-04-30.
Time Bomb is now known as the Temporal Rift and is cast by the High Templar.
Plasma Surge is no longer in the multiplayer version of the game, but will still be in the editor.
The Dark Pylon is now known as the Obelisk - primarily because it no longer cloaks units and no longer provides pylon power/supply. This change was mostly due to balance, since it is relatively easy to spam Dark Pylons everywhere and instantly have a Psi Storm recharge point to decimate incoming forces. Karune. 2009-06-08.

↑It seems like Time Bomb, which is in the current build and makes unit's movement speed and attack speed slow. Cydra. 2009-04-24. Instead of anti-grav, make it more-grav. Battle.net StarCraft II General Discussion Forum. Accessed 2009-04-24.
