Kuva Guardian

Wearing heavy armor and adorned in red cloth, the Kuva Guardians are among the fighting elite in the Queens' army. The Kuva Guardians will surround their enemies and with just a few well-placed blows, bring Tenno to their knees. They are followed around by mischievous Jester-like creatures that are quick to attack and are quite deadly.

At least one pair of Kuva Guardian and Jester will spawn in to protect the Kuva Siphon.

Mechanics
The Guardians' Kuva-infused Kesheg makes them immune to any conventional type of damage or crowd control as long as they are holding it. To be able to damage them, the player must utilize their Void powers:
 * 1) Switch to Operator mode by using Transference.
 * 2) Use Void Blast (melee ) in front to stun them, which will cause them to kneel down.
 * 3) Use Void Dash (holding crouch  and pressing jump ) to dash through them while they are stunned.

This will force the Kesheg out of the Guardian's hands, consequently making them vulnerable to all sources of damage. Do not let your guard down however, as they will pull out their devastating Twin Rogga pistols to keep up the attack. If given enough time they will pick their Kesheg back up, which will turn them invulnerable again.

Trivia

 * Kuva Guardians are stylized to represent the elder of Twin Queens.
 * As with the Kuva Jesters, Kuva Guardians feature unique dialog and voices not heard anywhere else throughout the Grineer line of common units.

Bugs

 * Kuva Guardians codex entry displays no weapons.
 * Puncture damage may randomly pierce their immunity.
