Mothership

The Protoss Mothership is an extremely powerful capital ship.

After the destruction of Aiur, and the attacks on Shakuras, the Protoss has decided to create safe havens within the sky. These glass domes that encase entire Protoss cities are a symbol of hope and power. Headed by the leaders of the Protoss Conclave, Motherships are not only armed to the teeth, but also act as a funnel for the Conclave's immense psionic power. Only deployed in the battle field during the most dire of circumstances, the Mothership has the capacity to turn a defeat to victory, and single handedly level small armies.

Statistics
As of May 21, 2007, the Mothership possesses 350 Shields, 950 Hitpoints, and 300 Energy; The Black Hole ability costs 150 Energy, the Time Bomb ability costs 75 Energy, and the Planet Cracker costs 100 Energy.

Strategic Properties
The Mothership's standard attack consists of eight psionic missiles, that spread out and attack all enemies within range. 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.

The true power of the Mothership comes from its three special abilities, though only two of them can be used in any one battle due to energy constraints. Each one has the capacity to turn defeat to victory.
 * Time Bomb - Slows down all enemy movement within a radius around the Mothership's position when it casts this. It also stops ranged weapons from reaching their targets. Ideal for dealing with static defense like Missile Turrets.
 * 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.
 * Black Hole - Creates a black hole in the air, drawing enemy air units into it to be destroyed. It's unclear if it also affects friendly and allied units.

From the demo, it is known that a normal Mothership doesn't have the mana to cast all three abilities in a row.

The design of the ship seems to be model on the city ship Atlantis from the TV series Stargate Atlantis.
