Voltigore

The Voltigore, not to be confused with Vortigaunts, is a gigantic and lumbering creature serving as the heavy support infantry of the Race X. Voltigore have four legs and two arms that end in scythe-like claws, and are distinguished by vivid purple stripes on their bloated carapace similar to those on a houndeye, though in a different color. These aggressive creatures use their innate ability to harness electrical charges to create a devastating ranged energy bolt attack, bearing some similarity to the Vortigaunt's green energy stream, although the Voltigore's energy attack is purple, and is much more lethal. At close range, they attack viciously with their claws. A player can recognize a Voltigore from afar by the unusual, electric-sounding bellows of the creature. When a Voltigore dies, its carapace explodes, causing massive damage to nearby creatures. It is notable that the Crab Synth manufactured by the Combine resembles these creatures, as well as the Antlion guard.

Baby Voltigores can be found later in the game. They are much smaller and weaker, lighter in color, and cannot yet use the energy attack commonly used by their parents. Despite this, they will make valiant efforts to use it, which simply produces a harmless purple spark. These versions also utter snorts which sound much like pigs when attacking. Baby Voltigore are only found in concealed underground nests and are closely guarded by the adults, suggesting that the Voltigore have a strong social structure. While at a great disadvantage in battle thanks to their under-developed bodies, Baby Voltigores are just as agressive as their parents and will not hesitate to attack the player.
