Mothership

The Protoss Mothership is an extremely powerful capital ship. They were originally constructed centuries ago during the Golden Age of Expansion, acting as command ships for Protoss explorers sent on expeditions; they were crewed by mystics and historians. As the Golden Age reached its end, the Motherships were left in place as monuments at the farthest reaches of Protoss exploration. After the Zerg devastated Aiur, the surviving Motherships were converted into warships and crewed by warriors, although they are also treated as holy shrines.

At the heart of each Mothership is a huge khaydarin crystal infused with an incredible amount of psionic energy. By tapping into this energy, a mothership can warp or crack the very fabric of spacetime itself. The devastating power of a Mothership can wipe out squadrons of enemy ships in the blink of an eye or lay waste to entire planets.

Strategic Properties
The Mothership's standard attack consists of eight disruptor pulses, that spread out and attack all enemies within range. These can attack both air and ground units. This makes them quite ideal as support in the back lines of a battle, dishing out pain to the front lines. While the Mothership has an immense amount of a hit points, they are incredibly expensive, and are not worth the risk of being exposed to open fire. Indeed, expect the enemy to throw everything they have in destroying these immense vessels.

Abilities
The true power of the Mothership comes from its three special abilities. Each one has the capacity to turn defeat to victory.

The Mothership can drain energy from allied units and use the energy itself.
 * Cloaking Field
 * The Mothership has the ability to nearby units. The ability has a very large range.
 * Planet Cracker
 * 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.
 * Share Energy
 * Time Bomb
 * Cast on a stationary area, Time Bomb protects units from damage.
 * Void
 * This ability can quickly destroy air and ground units in an area of effect.

In the most current development version of StarCraft II, the Mothership was reversed to a one-of a-kind unit.

Any abilities that do not make it into the final Mothership will still be available in the game editor.

Trivia
If the Blizzard game demonstration video is any indication, not to mention the voice of the quotes on the official StarCraft II website, it is thus far the only Protoss non-hero unit to be voiced by a female representative.

The Mothership's "Planet Cracker" ability is based on the energy beam from the ship in the introduction video for StarCraft I. That ship is the "conceptual anchor" for the Mothership idea.
