Ratchet & Clank Wiki

The one-eyed tyhrranoid was a type of tyhrranoid encountered in Up Your Arsenal, with appearances in Deadlocked and Secret Agent Clank. Considered the weakest version, they rely solely on numbers to attack opponents. A slightly stronger tiger-striped variant, known as the one-eyed tyhrranoid v2,[1] replaces the normal version on Kavu Island and any other areas afterwards. Once Dr. Nefarious used his Biobliterator in Metropolis, the tyhrranoids were turned into robonoids, with the one-eyed tyhrranoid thus being known as the one-eyed robonoid.[2]


Up Your Arsenal

Ratchet and Clank first encountered tyhrranoids on Veldin during "Save Veldin!". They appeared both as combatants, and co-pilots of the tyhrranoid attack ships. After this battle, they repeatedly encountered the one-eyed tyhrranoids during every battle with the tyhrranoids, sometimes were warped in by tyhrranoid saucers.

Ratchet uses the Tyhrra-Guise.

On Annihilation Nation, Ratchet won the Tyhrra-Guise, a device that allowed him to speak Tyhrranese.[3] He then used this to converse with one-eyed tyhrranoids in "Find Nefarious' Office", in which many of them were doorkeepers around Nefarious' base. Ratchet convinced these one-eyed tyhrranoids to let him past with several lies, including lying that he was sent to repair the holo-vid in the break room and offering to give one of them his sister's phone number, and often reassured them by simply saying he was not a lombax. Additionally, in order to raise a girder for Clank to use as a bridge to progress further, he fooled a tyhrranoid by claiming he had hid five bolts underneath it.[4]

One-eyed tyhrranoids appeared during the ambush at Holostar Studios. In addition to ambushing Ratchet, several of them would attack Ratchet by falling from a grav-ramp tower to try to knock him down, preventing him from reaching a titanium bolt.

After the one-eyed tyhrranoids were transformed into robonoids using the Biobliterator, they became more intelligent, and fought Ratchet in every battle against the robonoids. On Mylon, though one-eyed robonoids did not fight Ratchet, two of them appeared as doorkeepers in secure areas, blocking his path forward. To get past them, Ratchet had to use the Tyhrra-Guise. He tried unsuccessfully to convince the first to activate an elevator by claiming it was a fire drill, before instead saying he was there to give Dr. Nefarious a massage, frightening the robonoid into letting him past. He then tried to convince the second to deactivate a forcefield and let him through as Lawrence did not like its color. The robonoid was utterly unconvinced, but was persuaded to let him through as Ratchet offered to loan him the director's cut copy of an Amoeboids Gone Wild holo-vid disc.[5]


A one-eyed tyhrranoid appears to be getting married to another one in the holovision show, Queer Eye for the Tyhrranoid. However, the male tyhrranoid turns out to be a psy-tcopus.

Secret Agent Clank

Secret Agent Clank is in-universe fiction.
Secret Agent Clank is an in-universe holofilm in the Secret Agent Clank fictional series. Its events are a fictional movie within the Ratchet & Clank universe. Please see Project:Bulletin board/Canon for the wiki's coverage of canon.

Some of the standard one-eyed tyhrranoids were incarcerated on the Prison Planet. These tyhrranoids were fought by Ratchet in prison, ganging up with other inmates (including Thugs-4-Less, Megacorp gladiators, and reapers) to attack him. These one-eyed tyhrranoids also brought a three-eyed variant with them, though the three-eyed variant was a purple and larger variant of the basic one-eyed tyhrranoid, rather than the typical humanoid three-eyed tyhrranoid that Ratchet had fought during the events of Up Your Arsenal.


Concept art of the One-eyed tyhrranoid from Up Your Arsenal

The one-eyed tyhrranoids are the smallest variant of the tyhrranoids. They are blue and round with a short pair of legs and arms, and a mouth making up most of their torso. One eye extends from the top of their torso from a stalk. Their advanced counterparts, the one-eyed tyhrranoids V2, were tiger-striped and have a slit rather than a pupil in their single eye. The one-eyed robonoids were made out of metal and had orange eyes. A type of bluer one-eyed tyhrranoid that lack teeth appear as doorkeepers.

Tyhrranoids also seemed to have developed their own verbal language, heard while using the Tyhrra-Guise, consisting of burps and farts, and numerous hand movements, which was notorious for being rather easy to use as a variety of odd insults with only minor differences in the use of 'words'.


Being the weakest type of tyhrranoid, they are effectively dispatched with a single OmniWrench swing or with the use of any weapon, though preferably one more capable of defeating multiple weaker enemies at once, such as the Shock Blaster, Plasma Whip, or Lava Gun. They are also very useful for providing ammo for the Suck Cannon. Their attack is a short-ranged bite, which can be countered by dodging. Notably the tyhrranoid saucers are sometimes seen warping in new one-eyed tyhrranoids on the ground below them, but this is disrupted by damaging them.
