[Rank/Name] Spike Hydra (Variant) [Weapons/Equipment] Bangalores [Description] 
This variant deploys modified spike grenades that generate power to the top of the spike upon landing on top of the spike, creating a shield. This means while the Hydra in question is on top of the spike, it cannot be killed. This makes them much more dangerous to engage to compensate for the lack of teamwork from other Pacifican units. Unconventional means such as the Lodestone rifle will help to draw them from the spike. Less effective methods include destroying the spike the Hydra is on, as well as sticking Black Widow grenades to it, then as soon as it leaves its spike, detonate. An interesting note about the spike grenades is that they can be used by the player to give them a shield, also making them invulnerable to direct fire, though because of the lack of accompanying enemies with the Spike Hydra, this is of almost no practical use.
