The Kuva Jesters are special enemies that appear together with the Kuva Guardians in the Kuva Siphon sub-mission.

Jesters are tiny malformed creatures, that are limited to melee attacks. From time to time they will latch on Tenno and deal a series of fist bashes. Overall Jesters are quite weak and die easily to AoE attacks, but have a potential to be annoying on higher levels or during Operator form.


  • Kuva Jesters are stylized to represent the Worm, the younger of the Twin Queens.
  • When attacking a target, the Kuva Jester will make comical squeaking noises with each hit of the enemy it is currently latched to.
  • Due to not having any idle animation when unlatched, when viewed within the Codex the Kuva Jester will grapple and sit upon nothing and will float.
  • Unlike all other Kuva prefixed units, the Kuva Jester is the only unit not to share the red and black livery that is found within the Kuva unit, instead wearing a singular shade of tan.


  • When Mind Controlled, the Kuva jester will not possess the outline given by the power and will display on the enemy or ally the Kuva Jester is currently grappled to.
    • This does not allow for the Nyx Augment, Mind Freak to stack its bonuses with the target currently possessing the power outline.
    • This also applies to Tenno operators, Warframes and Rescue targets if the Kuva Jester is mind controlled mid-leap.
  • The Kuva Jester will sometimes not adopt its usual animation set upon spawning, resulting in the model becoming heavily distorted and disfigured until it dismounts the Kuva Guardian.
  • As with the Kuva Guardians, Kuva Jesters feature unique dialog and voices not heard anywhere else throughout the Grineer line of common units.


  • Nyx's mind control bug and deformed animations.
