The Slayer is a heavy combat strider.
After the fall of Aiur, the Protoss were hard pressed to compensate for the lost of Dragoon factories. Due to the actions of Tassadar and Zeratul, the Protoss began to understand the necessity of adapting to their new "life-style" and developing newer methods to combat the Zerg. Of their many advances in military technology, the Immortals stood out as prime targets to be added and warped into the Vaul arsenal.
Using captured schematics, Slayers are made for waging assaults with heavy artillery against armored forces. Like all annexed Protoss units, these new exoskeletons have inverted color schemes to outline the difference to their counterparts. Another visible difference in the Slayer's design is its more intimidating head component (Transformers - live action: The Fallen).
What made the Immortals interesting was their use of Hardened Shield technology. The ability to take the brunt of a Siege Tank barrage is by no means a small feet. As such, Slayers retain this particular ability despite its weakness to small attacks. To compensate for this flaw, standard Plasma shield emitters are equipped to the chassis to handle damage that would not activate the hardened shields.
Replacing the twin disruptor canons are powerful antimatter crystal launchers, which have the appearance of guns with shards growing out of them (Halo: Needler; Command & Conquer - Tiberium: Ravager). The launchers can further be augmented by charging the crystal ammunition with psionic energy. Once fired, the shards just pass through armor and plasma shields unimpeded until out of energy demolishing anything in their way (Transformers: Chaos). This makes Slayers ideal for confronting heavily armored and shielded targets. So powerful are these new exoskeletons, it is guaranteed that even Immortals will bleed (Warner Bros. Pictures: 300).
- Hardened Shields (passive) - reduces incoming heavy damage to 10. Ineffective to small caliber projectiles
- Vorpal Crystals - doubles bonus damage and ignores armor and plasma shielding (if present)
